What are the causes?

One of the first reason for hair loss resides in the seborrhea, a phenomenon that can be explained by the following way: the sebum invades the whole bulb of the hair follicle resulting in the thinning of the hair and eventually death by asphyxia. Besides, it is not rare that an important seborrhea comes with an increase in activity of the sudoriferous glands, shortening the life span of the hair.

There exist many other factors that contributes to the acceleration of hair loss especially:

• genetics;  
• the food;
• stress;
• some medical treatments and poisonings.
