What are the causes of hair loss?

Typical hair loss may of course have different causes. It can be triggered, for instance, by psychological stress, incorrect diet or disease. However, up to 80% of cases are affected by a hereditary predisposition.

Hereditary hair loss? (androgenetic alopecia)

In the case of hereditary hair loss, generally the hair disappears from the scalp. The most rapid advance is found on the crown. The hair follicles are no longer adequately supplied with nutrients, so that they atrophy. As time goes on the process is repeated and the follicles shrink ever more until eventually no more hair is visible.

What is this cycle and what happens then?

Due to lack of nutrients, normal hair growth does not take place. Between each phase of growth there are so-called rest periods which become ever longer as a cause of this.

So after a certain cycle, the hair that is brittle and poorly supplied with nutrients breaks off and it is followed by a rest period. In the next growth phase, the hair cannot draw up enough nutrients to grow strongly. Its strength decreases and it grows at a slower rate. After the hair has broken off again, the rest period continues until the next growth cycle can begin. This cycle repeats itself over many years, until finally the hair is no longer visible to the naked eye. The result is selective or complete baldness.

Eventually the scalp encloses the hair root and further growth is stopped completely.

What happens to the hair root?

Even after a very advanced process of hair loss with visible baldness, up to 99% of all hair roots are still in existence. It is just that they are covered and encapsulated by the scalp.
