Hair loss may be due to a lack of various vitamins such as vitamin A or vitamin B2. There are many reasons for hair loss, and it may also be caused by insufficient Qi and blood. It may be due to a lack of nutrition or anemia.

Hair loss is a normal physiological process in medicine. When the hair falls to a certain extent, the hair becomes sparse, and it is obvious that it cannot cover the scalp, which is a pathological disease.

A lack of vitamin A can lead to dry hair, more dandruff, and thinning hair. A deficiency of vitamin B2 can cause hair loss and excessive sebum secretion.
