1, first of all, don't wash your hair. Many men rely on short hair. If they are not washed for a long time, they won't smell strange. Women, on the other hand, don't like to wash their hair because of their long hair, but what they don't know is that if they don't wash their hair often, the oil secreted by the scalp and some dust in the air will slowly accumulate on the scalp, and the hair follicles will gradually block, and the growth rate of hair will be slower and slower, and the nutrition of hair will not keep up, and more and more will slowly fall off.

Secondly, the hair is often dyed. Nowadays, many young people often change their hair styles in pursuit of individuality and fashion. In fact, dyeing hair is very harmful to hair, which not only affects hair quality, but also makes hair lose nutrition and become thinner and thinner, eventually causing a lot of hair loss.

3. Then there is the hair caused by long-term dieting. Nowadays, many female friends have started dieting and losing weight early in order to wear beautiful skirts in summer. In fact, this way of losing weight not only hurts the stomach, but also causes the loss of protein in the body, and the nutrition absorbed by the hair will become less and less, gradually becoming soft and dry, growing slowly, and there will be hair loss.
