Alopecia, or the loss of hair, can be transient or definitive. However, the different care available can only achieve something in the case of a transient alopecia. If the alopecia is definitive, the hair follicles have lost their activity and hair cannot grow back. There are 3 main causes of alopecia :

  1. Androgenetic alopecia
  2. Telogen effluvium
  3. Alopecia areata


It is cause of alopecia you’ll see the most frequently. Its occurrence is often hereditary and it appears in a limited area on the scalp. The first areas hit are the forehead and temples. Then, it expands towards the top of your the head, only leaving air unscathed on the sides and the back.

There are only two ways to fight this alopecia. A local treatment containing 5-α-reductase can slow down the loss of hair. The REDACTIV formula we provide is one of thos treatments. Secondly, it is possible to transplant hair follicles in order for the hair to be able to grow again.

The androgenetic alopecia is a phenomenon seen mostly among men. But it also exists among women. However, its progression is much slower and doesn’t happen on the temples or the forehead particularly.


This phenomenon consists in a large and acute loss of hair. It often appears in a caractéristic psychologic context. We count among those long periods of stress, the months following childbirth and the post-operative phase. Other situations can be responsible of a telogen effluvium but those are the main ones.

In such cases, the loss of hair applies on the whole scalp.

The evolution of this alopecia turns out ot be positive in most cases. Your hair grows back with time without leaving any permanent damage. However, we advise you to follow a psychological treatment in order to go through a tough time, when it’s a cause of alopecia.


It is a localized alopecia as it appears on a particular spot on your scalp. It can expand and eventually reach all the hair follicles, thus preventing any growth. The alopecia areata can be linked to autoimmune diseases, but the main triggering factor generally reveals itself to be stress.

In most cases, the hair grows back in a few months. But it is susceptible to recurrences after this alopecia.

The REDACTIV formula as well as topical corticosteroids favor the growth of hair after an alopecia areata. But a psycholical treatment will most likely be needed to help resolver the issue.



An iron deficiency or malnourishment are two other causes of alopecia.

Some endocrine disruption causes such as a thyroid disfunction can also be responsible of a production deficiency.

Toxic causes such as chemotherapy, radiotherapy and combined hormonal treatments can lead to a case of alopecia.


Autoimmune diseases such as the lupus erythematosus or scleroderma happen to be a cause of the destruction of the hair follicle.

Infectious causes can also be responsible like the folliculitis, HIV, syphilis or ringworm.

Physical causes also exist such as a trauma or a burn, which end up destroying the hair follicles on the concerned area.


The pituitary has a role in the delivery of hormones into the blood circulation.

It can be altered by a genetic cause such as a congenital cutaneous aplasia, which is a rare anomaly of the skin.

But it is also possible to acquire an anomaly from a physical cause like trichotillomania, a tell of pulling your hair out.
