Alopécie expliquée : 8 causes et types d'alopécie

Alopecia Explained: Diving into 8 Different Causes and Types

Posted by Crüe Cosmetics on

Alopecia, a broad term for hair loss, is a condition that spans various types, affecting individuals globally. 

While alopecia is recognized, its nuances and the diversity of types may not be as widely understood. 

In this article, we'll delve into the different categories of alopecia and their causes.



Androgenetic Alopecia:

Commonly known as male-pattern baldness or female-pattern baldness, androgenetic alopecia is hereditary and affects both men and women. A sensitivity to the hormone DHT is the cause.

Men may experience a receding hairline and baldness at the crown, thinning in a christmas tree like pattern. 



Alopecia Areata:

An autoimmune disorder, alopecia areata occurs when the immune system mistakenly attacks hair follicles, resulting in hair loss in small, round patches. 

In severe cases, it can progress to total hair loss on the scalp (alopecia totalis) or the entire body (alopecia universalis).



Traction Alopecia:

Caused by tension and pulling on the hair, traction alopecia often stems from hairstyles that exert constant stress on hair follicles. 

Styles like tight ponytails, braids, or extensions can contribute to hair loss, particularly along the hairline.



Cicatricial Alopecia:

Also known as scarring alopecia, this type occurs when inflammation and scarring damage hair follicles. 

Cicatricial alopecia is irreversible if left untreated and may result from various sources, such as infections, autoimmune diseases, or physical trauma from heat or harsh chemicals.



Telogen Effluvium:

Characterized by diffuse thinning rather than specific bald patches, telogen effluvium occurs when a significant number of hair follicles prematurely enter the resting (telogen) phase of the hair growth cycle. 

Stress, illness, or hormonal changes are common triggers.




A psychological disorder where individuals compulsively pull out their hair, trichotillomania leads to noticeable hair loss. Treatment often involves behavioral therapy and support.



Chemotherapy-Induced Alopecia:

A side effect of certain cancer treatments, chemotherapy-induced alopecia results from the toxic effects of chemotherapy drugs on rapidly dividing cells, including hair follicles. 

Hair loss can vary, but it is often temporary.



Post-Partum Hair Loss:

Unique to women who have recently given birth, post-partum hair loss is a common occurrence. Hormonal fluctuations during pregnancy can prolong the growth phase of hair, but after childbirth, many women experience shedding. 

This type is usually temporary and resolves within a few months.



Understanding the different types of alopecia is crucial for individuals navigating hair loss journeys, and the diverse experiences people may have. 

Whether hereditary, autoimmune, or triggered by life events, seeking professional advice and support is key. 

A consultation with a certified trichologist can provide personalized guidance and solutions tailored to specific types of hair loss. Contact one of our hair specialists today and we will be happy to help you achieve your hair goals.
