Alopecia Femenina: Causas, Tratamientos y Rebrote

La alopecia femenina se caracteriza por la pérdida anormal de cabello en las mujeres. Las causas son diversas y el diagnóstico permite la adopción del tratamiento adecuado (Minoxidil, fármacos, tratamientos naturales...).



¿Qué mujer no ha encontrado un poco de cabello suelto en el baño? Si esta pérdida de cabello en general no es un problema, deberás llevarlo a consulta cuando ya no se compense con el crecimiento natural. 

La alopecia ocurre en las mujeres por varias razones. ¿Qué tratamientos para favorecer el pleno crecimiento? ¿A quién consultar? 

Definición: ¿qué es la alopecia femenina?

La alopecia es una pérdida de cabello anormal y generalizada que ya no se compensa con el crecimiento natural. "Distinguimos la alopecia crónica, cuando la pérdida de cabello es continua y el cabello nuevo se adelgaza, de la alopecia transitoria", especifica el Dr. Pascual Reygagne.

¿Qué explica esta caída del cabello?

El ex primer ministro apareció sin cejas, sin barba, sin bigote y con menos cabello durante una entrevista con BFM-TV el 2 de febrero. Confirma que tienes alopecia. ¿Qué es eso? ¿Cuáles son las causas de esta caída del cabello? ¿Tratos?

¿Qué tan común es la alopecia en las mujeres?

La alopecia afecta tanto a mujeres como a hombres (patrón de calvicie). A las mujeres les cuesta más aceptar. Pero, en general, es un poco menos probable porque las hormonas femeninas protegen contra la caída del cabello. “Se estima que el 40% de las mujeres desarrollan alopecia difusa después de la menopausia, que suele ser leve y discreta y solo requiere una consulta médica en los casos más evidentes”, especifica la dermatóloga.

¿Qué causa la alopecia femenina?

La alopecia transitoria ocurre dentro de los dos meses posteriores al episodio desencadenante, que puede ser:

El posparto.

Menopausia.

Una dieta inadecuada.

Operaciones quirúrgicas.

Una infección por covid-19.

Fiebre alta.

Pérdida de peso.

Una infección grave.

Tratamientos contra el cáncer (quimioterapia).

Caída del cabello después del parto: ¿cómo evitarlo?

Aunque el cansancio y el estrés suelen acompañar las primeras semanas de vida de una madre joven, la bajada de hormonas tras el parto también puede provocar alopecia posparto. ¿Qué hacer y cómo evitar esta caída del cabello tras el nacimiento del bebé?

La alopecia crónica, por otro lado, puede estar relacionada con:

Falta de hierro.

Desequilibrio hormonal, como el síndrome de ovario poliquístico (sop).

Un problema de tiroides.

La herencia, la causa más común.

Síndrome de ovario poliquístico (SOP): síntomas, tratamiento

El síndrome de ovario poliquístico (SOP o síndrome de Stein-Leventhal) afecta del 5 al 10 % de las mujeres y se manifiesta por la presencia de numerosos quistes o pequeños tumores benignos no cancerosos en los ovarios. Detiene la ovulación y puede complicar el deseo de embarazo.

¿Cuáles son los síntomas de la alopecia en la mujer?

“La alopecia en la mujer se manifiesta por la pérdida de cabello en la parte frontal del cráneo y en la parte superior de la cabeza, pero en general el cabello es denso en la parte posterior (región occipital)”, especifica la dermatóloga. 

“En el caso de la llamada alopecia androgenética, el diámetro del cabello es irregular, es decir, parte de la fibra capilar se adelgaza, pero no todo el cabello. Lo que se llama anisotrichia”, continúa el especialista. En este tipo de alopecia, el ciclo del cabello es muy rápido, es decir, crece y se cae muy rápido. “Un ciclo capilar normal dura unos 5-6 años, mientras que en este caso se reduce a 2-3 años, lo que cansa más rápido las raíces”, explica la Dra. Pascual Reygagne.

Alopecia androgénica: causas, diagnóstico, tratamientos

La alopecia androgénica es una forma de alopecia, es decir, la pérdida de cabello que puede ocurrir en hombres (calvicie) y mujeres, especialmente a partir de los 50 años. El tratamiento es posible dependiendo de las causas. Explicaciones.

¿Cómo combatir la alopecia en la mujer?

El tratamiento depende de la causa y el tipo de alopecia. En general, la alopecia en mujeres se trata con una loción tópica de Minoxidil al 2% aplicada tópicamente por la mañana y por la noche todos los días. 

"Si la alopecia es reactiva a una causa, se puede suspender el tratamiento cuando el cabello vuelva a crecer".

"Si la alopecia es crónica, se debe mantener el tratamiento, de lo contrario se reanudará la caída del cabello".

“Este tratamiento no requiere receta médica, pero no se recomienda tomarlo durante el embarazo”, indica nuestro interlocutor.

La alopecia también se puede tratar con métodos anticonceptivos adecuados, es decir, “con pastillas antiandrogénicas que permiten un menor crecimiento del vello, una piel menos grasa, menos acné y que favorecen el alargamiento de los ciclos de crecimiento del vello”, explica la dermatóloga.

En caso de deficiencia de hierro, se prescribirá un suplemento dietético.

Para la alopecia inducida por medicamentos, se debe suspender o cambiar el tratamiento.

Si la mujer sufre un desequilibrio hormonal, prescribiremos pruebas hormonales que se realizarán entre el segundo y el quinto día de la menstruación: "Tendrá que esperar de 1 a 2 meses después de suspender la píldora", recomienda el Dr. Reygagne.

Minoxidil para la alopecia, ¿cuándo usarlo?

La pérdida de cabello androgénica (relacionada con la edad y, en particular, con los efectos hormonales) afecta más comúnmente a los hombres, pero también puede afectar a las mujeres. La alopecia puede ser muy incómoda en la vida diaria, pero existen soluciones como el minoxidil.

“No existen tratamientos naturales realmente efectivos”

¿Existen curas naturales?

“No existen tratamientos naturales realmente efectivos para curar la alopecia (los masajes y los aceites esenciales no curan)”, dice la dermatóloga. “Sin embargo, podemos promover una dieta equilibrada. Una dieta vegetariana puede provocar deficiencias de hierro y vitamina B12 y, en este caso, será necesario recomendar suplementos”, especifica la especialista. 

La frecuencia de lavado no importa. “Es importante lavarse el cabello tan pronto como se ensucie, no debe obligarse a espaciar los champús porque las secreciones sucias tienen un lado irritante y pueden promover la inflamación”, explica el Dr. Reygaña. 

En este caso es necesario confiar en champús delicados de uso frecuente. “Pero los champús para la caída del cabello no existen. Debes saber que ningún champú tiene poder sobre la caída del cabello o su prevención”, insiste el Dr. Pascal Reygagne.

¿Vuelve a crecer el pelo después de la alopecia?

El cabello vuelve a crecer por completo en casos de alopecia, a menos que el desencadenante persista. “En el caso de la alopecia crónica, el tratamiento con Minoxidil permite que aproximadamente la mitad de los usuarios recuperen el crecimiento del cabello en unos 3 meses. 

Al inicio del tratamiento y durante las primeras 6 semanas puede producirse la caída del cabello, pero esto se debe a la eliminación de los cabellos muertos. El cabello que será reemplazado por cabello más grueso y fuerte, desarrolla nuestro especialista. 

"Este efecto puede molestar al paciente, pero es temporal y significa, por el contrario, que el tratamiento es efectivo", garantiza el Dr. Pascal Regagne. Para la alopecia transitoria, las mujeres generalmente tienen que esperar un año completo para recuperar el volumen y la calidad del cabello antes de la caída del cabello.

¿Las mujeres negras tienen más riesgo de alopecia?

“La alopecia afecta a todos los tipos de cabello por igual, independientemente de la naturaleza o el color de la piel”, responde enseguida la dermatóloga. La única peculiaridad del cabello rizado o muy rizado es que la alopecia suele denominarse "tracción". 

“Es decir, la alopecia se produce por peinados demasiado apretados, como trenzas y trenzas, o por técnicas de alisado”. Los dispositivos de calentamiento (llamas, planchas, rulos, etc.) debilitan el tallo del cabello y pueden promover la caída del cabello. Tienes que dejar de arrancarte el pelo, quemarlo, dejarlo solo. Minoxidil puede volver a crecer el cabello si deja de tirar de él antes de tiempo.

Cuidados en el Hogar: ¿Cómo Tener un Cabello Hermoso?

Algunos tips que te ayudarán a cuidar tu cabello casi como una profesional.

¡El primer paso es romper ciertos tabúes intransigentes! Los champús infantiles son más adecuados para nuestro cabello adulto, es decir, no contienen ningún principio activo curativo ni cosmético, solo activos desenredantes y ligeramente supergrasos, pero sobre todo no son adecuados para nuestro cabello adulto. 



¡Lavarse demasiado el cabello lo rompe o lo daña, falso, arco falso! Luego, debes dominar el arte del lavado para tener un cabello hermoso y saludable (¡sí, es un arte!). Porque el cabello y el cuero cabelludo limpios son esenciales para la buena salud de tu cabello, ¡sobre todo porque lo lubricas todos los días!

Todo comienza con el cabello limpio, y para ello es necesario lavarlo con frecuencia para que sea más fácil de peinar, aportar brillo, lucir más bonito y sobre todo más flexible. 

Por lo tanto, en promedio, debe lavarse el cabello al menos una vez por semana (idealmente dos veces por semana) y luego elegir el champú y acondicionador ideal para su tipo de cabello, para cabello tratado químicamente (decolorado, teñido, alisado) seguido de una mascarilla para el cabello.

El arte del lavado para un cabello hermoso

¿Cómo hacer un champú que no dañe el cabello y estimule su crecimiento? Primero hay que mojar bien el cabello antes de aplicar el champú, luego no lavar directamente en la cabeza, sino verter una nuez grande con la mano antes de aplicarlo de raíz a puntas. Cuando te lavas el cabello, es imprescindible lavarlo al menos dos veces. 

El primero para quitar toda la suciedad, grasa y demás residuos y el segundo para lavar de verdad, además verás que el champú quedará más espumoso en este segundo lavado.

Si es posible, lávese el cabello, inclínese sobre el lavabo o la bañera, para activar la circulación sanguínea en el cuero cabelludo y la línea del cabello. Use las yemas de los dedos para frotar o masajear el cuero cabelludo, nunca use las uñas ni ningún otro objeto (como un peine) porque esto irrita el cuero cabelludo. Masajee suavemente en el cuero cabelludo con movimientos circulares (no en el cabello), comenzando desde el cuello y avanzando.

Hazlo durante unos minutos para activar la eficacia de los principios activos que contiene el champú y darle tiempo de actuar. Cuando llegue a la línea del cabello, aplique un poco más de presión, mientras usa los pulgares para masajear las orejas hacia las sienes, luego enjuague.

Emplea acondicionador

Usa siempre un acondicionador o tratamiento post-champú después de cada champú, suavizan las micropartículas que recubren cada mechón de cabello y protegen tu cabello de todo el clima y otra suciedad que se acumula allí y daña tu cabello. 

Aplicar el acondicionador sobre el cabello secado con toalla, masajear y dejar actuar unos minutos (5 a 10 minutos dependiendo del producto y estado del cabello). Tómate tu tiempo para realizar este ritual que, si se hace bien, convierte tu champú en un gran momento de descanso y relajación, cuyos beneficios sentirás al final.

Enjuague bien el cabello después, ya que el residuo del champú deja las hebras opacas y también estresa el cuero cabelludo al enjuagar, ya que este mismo residuo provoca la caspa. 

Terminar de enjuagar con agua fría, lo más fría posible para tensar las escamas de las cutículas, refrescar y tonificar el cuero cabelludo. Un pequeño consejo de la esteticista Sandrine Jeanne-Rose (Kanellia) es añadir al agua de aclarado un poco de vinagre de sidra o de zumo de limón, que tienen grandes propiedades suavizantes y antical.

Usa loción protectora

Ate su cabello en una toalla caliente para absorber el exceso de agua. No seque el cabello con una toalla enérgicamente, pero déle palmaditas suaves para evitar que se quiebre. 

Pero muy importante si vas a utilizar un secador de pelo para secarte el pelo, primero aplica una loción protectora que envolverá tu cabello en una película protectora, ya que el calor del secador es muy dañino para tu cuero cabelludo.

Si tienes la suerte de que un amigo lo haga por ti, sería aún mejor. De lo contrario, regocíjate, no es tan difícil y siempre estamos mejor servidos a nosotros mismos. 

Siempre lave sus peines y cepillos después de cada lavado y asegúrese de que todos en la casa tengan su propio peine para que todos mantengan alejados los gérmenes. Use un peine de dientes anchos con puntas romas para desenredar el cabello. Si usa un cepillo, asegúrese de que sea de cerdas naturales (las cerdas de jabalí son las mejores), ya que desenredan el cabello con menos desorden y no lo rompen.

Update: Meet Everything New in MacOS Monterey

Officially available for almost two weeks, the new version of macOS is packed with a ton of new features. If you're still hesitant to install it, these five new features should win you over quickly.





On October 25, Apple officially released macOS Monterey, the latest version of their Mac operating systems. After nearly four months of beta testing, Mac users with an eligible machine can now choose to install the new version of macOS on their computer. by going directly to "System Settings" in the "Software Updates" menu.


While the more adventurous will likely have already installed this major macOS update, the more savvy might wait to get feedback from new users first before deciding to take the plunge.


Because, in addition to the likelihood that some commonly used programs will still not work on Apple's new operating system, some Mac owners simply "ditched" their computer after installing macOS Monterey.


Which dampens the enthusiasm a bit, although these problems are still fairly rare on the scale of the number of users worldwide.


Note, however, that some new features available in beta versions of macOS Monterey are not yet available in the stable version of the operating system. This is the case, for example, with SharePlay or the Universal Command function that allows you to use the Mac keyboard and mouse on a nearby iPad.


But if you're still one of those doubters, some new features in macOS Monterey may quickly convince you to cross the line.


🎞️👇VER PELICUL4S🎞️👇

Direct text


Since iOS 15 does it so well, macOS now knows how to find and extract text from your images. With Monterey, you can very easily interact with all the text that appears in images, whether they are stored on your Mac or displayed in the Safari web browser. macOS Monterey automatically recognizes text displayed in images and lets you choose to copy and use it in another application after pasting.


the text. Even better, when the selected text is a phone number, address, or email address, macOS offers directly to make a phone call, find your location on a map, or send an email.


iCloud private streaming


Currently available in beta as of iOS 15, iCloud Private Relay is a new service implemented by Apple to protect your Safari browsing by hiding your IP address.

All data sent from your Mac is encrypted and passes through independent Internet streams, preventing the websites you visit from learning your IP address, DNS activity, location, and web activity to build their profile of advertising to target ads to you.


To enable it, go to System Preferences, then under your Apple ID, check the Private Broadcast (beta) setting.


Note, however, that iCloud Private Relay is only available to iCloud+ subscribers, meaning paid iCloud subscribers who signed up for at least $0.99 for the 50GB storage offer. iCloud.


Facetime


This is one of Apple's best projects in macOS Monterey. FaceTime, the audio and video calling app is getting a lot of new features.


All you have to do is start the call by selecting from the application Create a link, which you can then send to your correspondents. They just need to open it in their regular web browser to join your FaceTime call.


Quick note


Quickly taking several notes with a single click, just like you would a small note, without the risk of losing content, is now possible.


With Monterey, Apple introduces a Sticky Note feature that, as the name suggests, lets you quickly create a note, which then automatically syncs with the Notes app to make sure it's backed up.


To quickly take a note, hold the mouse pointer in the lower-right corner of your Mac screen and click the small gray square that appears. A new blank note will open so you can quickly type whatever you need.


Sticky notes are also available under "Add to Sticky Note" from the right-click context menu in Safari after text is highlighted.


In theory, the annotation contains the selected text, as well as the URL of the page in question where you can add your comment. If this feature sounds appealing, it actually, at least for now, still seems a bit wonky as we haven't consistently been able to get it to work properly.


Aerial game


With macOS Monterey, your Mac can become an AirPlay receiver. Specifically, you can now stream your presentations or mirrored videos from your iPhone to your Mac display. It's also possible to use it as an AirPlay speaker: Start a song on your iPhone and play it through your Mac's built-in speakers.


Be warned though, AirPlay on Mac is not available on some older machines. To qualify, you must have a MacBook Pro or Air 2018 or newer, iMac 2019 or newer, iMac Pro 2017, Mac Pro 2019, or Mac mini 2020 or newer. 


As for the iPhone or iPad, it will be essential to have an iPhone 7 or later, an iPad Pro of the second generation or higher, an iPad Air of the third generation or higher, an iPad of the 6th or higher, or an iPad mini 5th generation or higher.

We absolutely hate computer viruses. But do you know exactly how viruses can harm your computer?


Simply put, a computer virus is simply a type of program that causes your computer to behave in an unwanted way. It could be a dangerous infiltration designed to crash your computer, delete important files, track your habits, or give hackers access to your personal information... 


A virus is a big nuisance. Some viruses such as Locky virus and CryptoLocker, also known as ransomware, delete computer files, encrypt them or even change the file extension to .locky or .encypt. Other viruses hide files and do not allow users to hide them.


It's certainly true that a virus is something you want to remove as soon as you find it. Among the many options, many users try to remove viruses using CMD.


Why can you remove a virus using CMD?


In fact, using command lines does not scan or remove viruses directly from your computer or external storage device. CMD helps you achieve your virus removal goal by displaying hidden viruses on a partition or disk. 


You can then delete the suspicious files. Since viruses are always hidden, you should expose them and then delete the virus files. So how can you see potentially hidden virus files using CMD? All you need is the attrib command.


The attrib command is a command line command used to view, set, or remove attributes for files or folders in the selected location. And then you will know where to find it and delete it.


How to remove a virus using CMD


Now follow the steps below to remove the virus from your computer or storage device using CMD.

R – Represents the "Read Only" attribute of a file or directory.

S: The "System" attribute transforms the selected files or folders from user files to system files.

H - "hidden" attribute.


Syntax of "attribute":


ATTRIBUTE [+ attribute | – attribute] [pathname] [/S [/D]]


'+ / –': To enable or disable the specified attribute.

'attribute': As explained above.

"pathname": The path where the destination file or folder is located.

'/S' - Search the entire path, including subdirectories.

'/D': includes all active directories.


Here is the correct syntactic order for the attrib command:


ATTRIBUTE [+R | -R] [+A | -A] [+S | -S] [+H | -H] [+i | -I] [drive:][path][filename] [/S [/D] [/L]]


If you get the "Access Denied" message:


Make sure you have started the command prompt as an administrator

Make sure the file/folder is not in use

Check the checking account permission and make sure you have full control over the file/folder (right click on the file/folder/partition and go to "Security")

Use the CHKDSK command to check for file system errors (start the command prompt and type chkdsk /f [drive letter] :)

Besides using CMD, there are other methods to remove a virus from your computer or storage device, such as using antivirus software, Windows Defender, and formatting the storage device.


Method 1. Run Antivirus


Almost all computers are equipped with antivirus software. If you find that your computer is infected with a virus, it may be worth using antivirus software.

Free Antivirus: Which is the Best to Protect your Computer?

With all the malware that is spreading today, it is unthinkable to have a PC without protecting it with an antivirus. In particular, there is a free software. 




But how do you know which antivirus is better than another when you know nothing about computers? Experience our tips and a selection of the best freeware right now.


In the age of connected everything, malware is not to be taken lightly. Especially since these now take many forms, so it is important to adopt a good defense. 


Of course, not everyone can afford to pay for their antivirus. In this case, free antivirus seems to be the ideal alternative. It doesn't offer all the features of its paid counterpart, but it still provides effective protection for your PC.


Let's just say that the best free antiviruses are equal in terms of malware protection and impact on computer performance. So much so that it's hard to pick one. Here are some ways to find the shoe that fits you.


What are the best free antivirus?


In this folder we have added the latest evaluations from independent laboratories AV-TEST in Germany, AV-Comparatives in Austria and SE Labs in England. Each lab regularly tests leading antivirus products to assess their ability to detect zero-day malware and other threats. 


They focus on specific criteria (performance impact, behavior against recent threats, ergonomics, protection index, number of malware blocked, number of false positives). Summarizing your tests allows you to assign overall averages and rank them as follows.


Avast: 99.1

AVERAGE: 98.9

Avira: 98.6

Windows Defender: 97.2


Important details: Kaspersky Security Cloud Free ranks highly in our comparison. But we decided to remove it after it was blacklisted by the Federal Communications Commission. 


This means that US authorities can no longer use the Russian publisher's security packages. This decision was taken in response to the conflict in Ukraine, the scene of a series of cyber attacks orchestrated by Moscow.


We have also removed Bitdefender Antivirus Free Edition from this comparison as the publisher simply decided to remove their free solution.


Avast One Essential


In the small game of scores collected by the three labs, Avast achieves an excellent overall average of 99.1/100. The publisher now offers a free solution called Avast One Essential. This effectively detects and neutralizes malware, particularly relying on its extensive threat database. It also detects unsafe websites and phishing attacks.


Several additional features are included to ensure the security of your online banking and transactions, as well as your privacy on WiFi networks that are open to everyone. But that's not all. 


A tool tells you if your bulk words have been compromised. For streaming, Avast One also has a VPN, but limited to 5 GB / week and a website.


You can also have a firewall that blocks any unauthorized access via Wi-Fi and the Internet. Harmful websites and downloads will also be blocked. And tracking files can be removed, a good way to see advertisers.


What about system load? In a May-June 2022 test, AV-Test reports that the slowdowns caused by Avast One are 9% for web browsing, 1% for downloads and 11% for running software (on a standard PC). Nothing alarming really. 


As mentioned at the end of the article, the data collected by Avast is usually encrypted, but distrust is still justified after the controversy involving its former subsidiary Jumpshot.


AVG Antivirus Free is software that also stands out for its imperviousness to malware. Proof of this is its very high score obtained in the last independent tests (overall average 98.9/100). 


In addition to its proven ability to block a wide range of malware thanks to its six layers of protection, this free version also reserves extensions for your browser. These are meant to protect you from phishing attacks, suspicious websites and dangerous downloads.


An email agent is also available to block fake attachments and phishing links that can steal your personal data. In addition, a tool is provided to analyze the performance of your computer. This free version does not include other features as these are reserved for paid suites. Slowdowns caused by the security product are particularly noticeable online (19% on a high-end PC), according to AV-Test.


When we tested the antivirus, we didn't mind the invasive ads. However, AVG Secure Browser was installed automatically. 


Finally, note that Avast Software publishes AVG, so it is also involved in the controversy over the collection of potentially anonymized data. What to suspect about respecting user confidentiality. However, as of July 2019, a clear option to accept or decline the collection has been created.


Avira Free Antivirus


On the third step of the podium we find Avira Free Antivirus, which is not at all worthy with its final average of 98.6/100. In particular, Avira Free Antivirus offers you good protection against malware. The software receives regular updates to recognize new malware signatures.


But this free edition also has some great features to boast about. Password manager, performance optimization tool, browser tracking blocker... A free VPN is also included. However, it only allows you to enjoy 500 MB per month of encrypted traffic and a different server location. An interesting game, but necessarily too easy compared to the paid unlimited VPN versions.


In terms of performance impact, this antivirus causes a 23% slowdown in web browsing (17% on a standard PC), according to AV-Test. In terms of privacy, Avira is very clear: "As a German company, we do not track your activities and do not sell data to third parties."


Alternative free antivirus: Windows Defender


While Windows Defender can't beat Avast or Avira in malware protection, it's starting to take the lion's share. Combining all of its scores, we gave it an average of 97.2/100. For basic free protection already installed on Windows PCs, Windows Defender does the trick.


It also offers other features to increase your security, such as an anti-intrusion firewall and a parental control system. SmartScreen also helps fight phishing and online malware. And this in both Microsoft Edge and Chrome (via an extension). Based on a database of reported phishing and malware websites, SmartScreen will automatically block the malicious website or downloaded files.


Despite efforts in recent months, Microsoft's original solution still causes some delays. Thus reaching the second-to-last position in the ranking based on the performance established by AV-Comparatives with an impact score of 24.6. 


AV-Test, for its part, reports that slowdowns occur mainly during the installation of programs (17%).


Please note: Windows Defender updates are downloaded automatically, so your computer is always protected. The software is disabled if you enable other antivirus software. And it comes back if you uninstall its competitor.
