Hair loss is a natural phase of the hair growth cycle. You can lose between 50-150 hairs per day. Even if it seems that you lose a multitude of hairs there is no need to worry. As long as it is a normal hair growth phase – its density remains stable.

Hair loss statistics
A healthy person can lose between 50-70, and even 150 hairs a day. If you lose more than 150 hairs you should consult a specialist. People have about 100,000 hairs on their heads. Each follicle produces a hair which grows within the range of a few to a dozen millimeters a month. A hair growth phase takes on average 2-6 years. Just before the hair falls out it is in a resting phase. It is quickly replaced with a new hair and the whole cycle starts again. A minimum of 85% scalp hair should be in a growth phase. Hair in a resting phase regularly falls out which is a natural physiological process. The majority of people observe that they lose about 50-100 hairs daily.
