If you look through some research data, you will find that it is commonly thought that the process of hair whitening starts from the hair follicles in the scalp. Generally speaking, there are about 100000 hair follicles on a normal person's scalp. In a person's life, each hair follicle can grow several hairs. At the bottom of the hair follicle is the hair "processing factory", where cells work together to produce colored hair. Melanocytes produce melanin and transfer melanin to hair in the form of melanosomes. Previous researchers did not pay attention to the role of Wnt signal protein in melanocytes but generally believed that the life of melanocytes was relatively short. When the hair lost part of melanin, it would turn grey. If it lost all of the melanin, it would turn white completely. Now, the secret hidden behind white hair is about to be revealed. Understanding how the cells in the hair cooperate is helpful for scientists to study the regeneration of hair tissue.
