Is it easier to lose hair in winter?

The reason for the increase of hair loss in winter should start from the hair growth cycle. Hair can be divided into three stages, that is, from growth period, rest period to shedding period, and then new hair grows in the next growth period. In other words, hair grows and stops periodically, but all hair is not in the same cycle. It grows and falls off at any time. The speed of hair growth and shedding varies with gender, age and season. The increase of hair loss in winter can be traced back to summer. In hot summer, strong ultraviolet rays will have an adverse effect on hair health. If skin cells are overexposed to sunlight, it will cause different degrees of congestion, inflammation and other adverse reactions. Mild injuries can be repaired naturally within a few days, while severe injuries can cause edema or necrosis of the skin, degeneration of collagen fibers and elastic fibers in the dermis, reduce the toughness and elasticity of the skin, and affect hair and nutrient supply. Hair in hibernation is exposed to the hot sun, and it is easy to fall off after 40-70 days. Therefore, the hair that has been "fried" by the summer sun will fall off in autumn and winter. This has led to an increase in hair loss in winter.

To reduce the increase of hair loss, we should try to avoid or reduce exposure to the hot sun in summer. Wear a hat for outdoor activities and a swimming cap for swimming. Wash immediately after swimming and use moisturizing conditioner.

Now because the climate is relatively dry, the hair will appear drier and more fragile than usual, so it is advisable to use conditioner and moisturizing shampoo. You can also do some hair massage frequently to promote the growth of new hair. The method is to open your fingers and press them on your head, and massage the whole scalp from front to back and from top to bottom in turn. At the same time, we should eat more foods with high protein content, such as egg yolk, milk, beef and bone marrow.
