There are about 100,000 hair follicles on each person's scalp, and each hair grows for about 2-4 years, after which it enters a resting phase and falls out naturally after a few weeks. It's normal for people to lose dozens of hairs a day, just like animals shed their hair. In late summer and early autumn, a large proportion of hair is in the recuperation period, which is why hair loss is more severe in autumn.
Even if you lose more than 100 hairs a day, it is normal, but if you wake up in the morning and find more than 50 hairs on your pillow, and you lose a lot of hair when you comb your hair, it may be abnormal hair loss. Especially when you see the hair that has fallen out, if the tip of the hair is the same thickness as the root of the hair, and there is a small white spot at the root, it means that the hair is still healthy when it falls out, and its loss is not normal.

Race, also known as "race", is a group of people with certain common genetic characteristics (such as skin color, hair color, hair shape, eye color, head shape, nose shape, etc.) in physical morphology, and these characteristics are formed by long-term adaptation to the natural environment in a certain area. In the early days of human development, groups of human beings lived in isolation from each other in their natural geographical environments for a long time.
