How much hair is normal to lose after washing your hair

When washing their hair, many people will find that they are losing a lot of hair. Under normal circumstances, each person loses 60 to 80 strands of hair every day. If the number of hair loss exceeds 100 or even more each time, it is a pathological phenomenon of hair loss.

1. Under normal circumstances, each person can lose 60 to 80 hairs a day. More hair loss often occurs when combing or washing the hair. This is because the hair that is in the resting phase and has not yet fallen out is pulled and falls off, so there is no need to be overly nervous. However, if a person loses more than 100 hairs a day, causing hair thinning, it becomes a disease called alopecia.

2. 70% of patients suffer from seborrheic alopecia. There are two main types of hair loss: one is seborrheic alopecia, which accounts for about 70% of all hair loss patients. One is neurotic alopecia, which accounts for about 29% of patients with alopecia, and hair loss caused by other reasons, such as tinea versicolor, syphilis, etc., accounts for only about 1%. With the development of society and the accelerated pace of people's life, work and study, the psychological pressure people bear is increasing, and the incidence of hair loss among the population is also increasing.

3. The scientific name of seborrheic alopecia is androgenic alopecia, which is a multi-gene genetic disease that is more common in men. The disease process of seborrheic alopecia progresses slowly, usually starting at the age of 20 to 30, and is characterized by gradual thinning and loss of hair. For men, it usually starts from the sides of the forehead and gradually extends to the top of the head. Moreover, due to excessive sebum secretion, some people have greasy hair, which will become dry and dull in the long run.

4. Neurotic alopecia includes alopecia areata, alopecia totalis and alopecia universalis. This disease is characterized by rapid progression, and complete baldness can occur within a few months, days or even overnight. Neurotic alopecia is hair loss caused by excessive mental stress.
