I don't know if you have ever seen such a situation, not long after washing your hair, you swept your hair and it was "snowy" again, and dandruff was flying all over the sky. Is there anyone who also has such troubles, even though they wash their hair frequently, but they always have dandruff ......
What should we do?How to scientifically maintain scalp health?Today, Lotus Leaf Health will talk to you about these contents.
We know that the scalp is made up of the dermis and epidermis during metabolic processesThe basal cells of the scalp absorb nutrients directly from the dermis, and continue to proliferate to form new cells, which move to the epidermis to form epidermal cells, and eventually the keratinized and necrotic cells fall off on their own, which is dandruff.
In a healthy state, the shedding and regeneration of cells are in dynamic equilibrium, and keratinocytes shed slowly and very little, and the diameter is 0Around 02 mm, we can rarely see it with the naked eye.
ButWhen the scalp is dysfunctional, there is a noticeable flaky flake between our scalp and hair, which is usually white or off-white, scattered in the hair.
The causes of dandruff tend to be concentrated in the following two directions.
1.Physiological dandruff
The metabolism of the scalp is disrupted due to external factors, and the defense function becomes poor. For example, the moisture of the scalp decreases, the hair is not nutritious, etc., and the changes in external temperature and humidity will affect the blood circulation of the scalp and cause the increase of dandruff, which is often affected by the autumn and winter seasons.
