Don't rush to buy an anti-dandruff shampoo when you suddenly notice an increase in dandruff. Dermatologists point out that dandruff is often caused by unbalanced scalp oil caused by stress and affects keratin metabolism. It is recommended to relax and reduce stress. At the same time, you may wish to add nuts, whole grains, pumpkin and mushrooms, egg yolks and other foods, which can supplement biotin, vitamins B, D and zinc, and help to regulate fatty acids.

There are 3 main reasons for dandruff
Many people have discovered recently that white dandruff floats down just by ripping their hair. Zeng Depeng, director of the Department of Dermatology at Tai'an Hospital, said that there are 3 main reasons for dandruff. The first reason is Bacillus dandruff infection, the second is abnormal keratin metabolism, and the third is that weather changes and high pressure affect sebum secretion. These three reasons may exist at the same time, or cause and effect each other and affect skin desquamation.
Because Bacillus dandruff is nourished by triglycerides secreted by scalp sebum, free fatty acids are produced after catabolism. Free fatty acids are highly irritating to the skin, causing inflammation and redness of the scalp, which will slough off when the skin is damaged. These factors may affect keratin metabolism. The keratin that was originally metabolized in 28 days may shorten or prolong the metabolism time. Some will accumulate on the scalp and some will fall off.
And the weather changes or emotional stress, staying up late, etc. will cause excessive oil on the scalp. The human epidermis has dandruff spores, and the excessively secreted oil becomes the trophoblast of dandruff spores, and the colony increases.Abnormal metabolism of raw and keratinous cells leads to a vicious cycle of dandruff.
People with dandruff may have scaling problems all over the body
Although anti-dandruff shampoo works the fastest, many people actually have problems with keratin metabolism throughout the body. It's just because the scalp sebaceous glands are the most densely distributed and the scaling is the most obvious, but in fact the whole body has scaling problems. Zeng Depeng said that some products have promoted biotin nutritional supplements before, but he thinks it is not necessary because biotin can be obtained in many foods.
Food supplements biotin, and the whole body skin is maintained
Zeng Depeng said that biotin is commonly known as "vitamin H", and it is actually a member of the vitamin B group. Biotin is found in many foods, such as egg yolks, nuts, whole grains, mushrooms such as shiitake mushrooms, and visceral livers, kidneys, etc., which contain vitamin B and biotin. Mushrooms also contain vitamin D, and nuts, meat, and seafood contain zinc. Simply supplementing nutritional supplements, some people will have mild side effects such as nausea, it is better to take it from the diet and maintain the skin of the whole body.
Anti-dandruff shampoos have a variety of ingredients to choose from depending on the condition
but anti-dandruff shampoos are still the easiest to control dandruff. At present, there are many anti-dandruff shampoos with different ingredients on the market. Some of them mainly control scalp colonies, and some control scalp oil. However, because these functions can control the metabolism of scalp keratin, they all have the effect of removing dandruff. Unless the general anti-dandruff shampoos on the market have limited effects, you may need to choose ingredients with different effects depending on the situation. For example, if there are too many spores, you can choose ketoconazole, coke-containingThe oil component controls colonies. Or keratin metabolism disorders, to choose salicylic acid ingredients, and seborrheic skin, you can choose shampoo containing zinc ingredients.
