There are many causes of hair loss and it is not necessarily due to vitamin deficiency. If the patient is now losing hair, blindly taking vitamin supplements may not necessarily have a good effect. However, taking some vitamins appropriately, such as vitamin B2 and vitamin B6, can promote lipid metabolism well, control oil secretion in the body, reduce scalp oil, and reduce hair loss to a certain extent. This method of vitamin supplementation is only an auxiliary treatment and cannot cure hair loss at its root. It is recommended that patients should go to the dermatology department of a regular hospital in time for examination and specialist treatment. Usually, we should pay attention to reduce staying up late, rest more, use good quality shampoo, avoid spicy and stimulating food and quit smoking and drinking in order to effectively prevent hair loss.
