Bacillus dandruff can make sebum secretion exuberant and produce dandruff.
Fourth, scalp cell dysfunction.

After the cells in the basal layer proliferate, they gradually mature and push out, and finally the stratum corneum becomes lifeless and falls off. If there is a problem with this process, it is that the maturation process of scalp cells is incomplete. In other words, it will peel off. For example, the elderly, malnutrition, chemotherapy or psoriasis patients, the increase of dandruff is caused by this.
