Type of alopecia hair loss

Alopecia is premature hair fall or absence of one or more body parts. Its causes are many and the types of alopecia are classified as follows:

 Non-scarring alopecia:
They are very common and can be improved or cured through treatment and even some revert spontaneously without being treated. In this type of alopecia the hair follicle has a pathological behavior but still alive except alopecia extending over long periods (common or androgenetic alopecia).

Androgenic Alopecia:
 It is also known as androgenetic alopecia, or pattern baldness premature. It affects many men and women rarely.

 
If you suffer from androgenetic alopecia, like most of the men I recommend you take a look to the left and check the Norwood Scale what type / degree of alopecia have.
You will be very useful to know if a treatment can give results. If your degree is very advanced (5, 6 or 7) have to think about surgery or just accept that you are bald. There are no treatments that have proven effective in such advanced degrees.


Androgens are the hormones responsible for hair loss and that is why many current treatments inhibit the production thereof.
If progress continues baldness and hair follicles die, the process becomes irreversible and no treatment exists to restore the situation. It can only be repaired by transplanting living in other areas towards the crown follicles and entries; microfollicular capillary. Ideally, of course, is to fight the fall while the follicles are alive.
Women are luckier than men because androgenetic alopecia appears only on the front of the scalp, leaving hair thinning but rarely gets to have completely depopulated areas and in man. 

 Alopecia areata: the cause is unknown, but its symptoms are clear: round patches on the head of hair completely depopulated. Alopecia totalis (AT) is when the scalp hair is lost completely. In cases of Alopecia universalis (AU), the whole body hair is lost.
