How much hair loss is normal?

Normally, they serve as an ornament and a full head of hair is a sign of vitality and health. On average, every person has around 100, 000 hairs. These "live" for about 4-6 years and grow one centimeter per month - in spring but also more. But that does not happen continuously, because every hair has its time. Meaning, it has growth (anagen phase), transition (catagen phase) and resting phases (telogen phases). When the resting phase is complete, the hair finally falls out.

Hair loss: normal or not?

First of all, it can be assumed that a hair loss of up to 100 hairs is normal. Since the spontaneous impression can be deceiving especially with long hair, one should definitely make the effort of recounting. Morbid hair loss should also be distinguished from the plant-related, androgenetic alopecia. It is the typical hair loss in men, which can start at a young age, but increases from middle age but more and more.

When to the doctor in case of hair loss?

In addition, the hair loss can occur suddenly - almost overnight - and in a circular shape. In technical terms, this phenomenon is called alopecia areata and mainly affects children and young people. The cause is an inflammation of the hair follicle, which is probably caused by a reaction of the immune system to the own body. In addition to a number of other disease-related causes, there is also occupational alopecia, which can be caused by persistent pressure (headgear) or pull (eg ponytail) If all natural causes can be ruled out, you should go to the dermatologist for examination. There are several methods of investigation available, such as the trichogram used to assess hair root status. For this, a tuft of about 50 hairs is plucked and examined microscopically. In addition, microscopic examination of skin samples or blood tests can be performed.
