Your hair is afraid of sun

amino acids in hair are the key part to ensure the health of hair, but under the sun exposure, amino acids will absorb some ultraviolet rays and produce "photodegradation" effect. In this degradation process, "free radicals" that directly lead to hair aging will be produced, making hair dull, fragile and inelastic.

The process of hair pigment damage is similar. The color of hair comes from "Mailanin" pigment. If it is exposed to the sun for a long time, the content of "Mailanin" will decrease, making the hair pale or yellow, and it is easy to cause water loss and make the hair dry.

in addition, your hair will be hurt when you swim. Under the influence of ultraviolet rays, water will produce a chemical reaction similar to that of bleach. After swimming outdoors for a long time in summer, you will feel that the hair color seems to be pale and the hair quality is getting worse. In fact, it is not only when swimming that such a result will occur, as long as there is a certain humidity in the air, it is enough to cause this chemical reaction.

In the weather with moderate ultraviolet radiation, it is best to carry hair care and nourishing water with you and use it every 4 hours; In the weather with strong radiation, you must insist on using sunscreen shampoo and hair care products, and use hair care nourishing water every 2 hours when you go out; When the ultraviolet radiation in the weather reaches extremely strong radiation (ultraviolet index > 9), sunscreen nourishing water should be used at any time. When outdoors, you should wear a hat and sunglasses, put on a sunshade and wear light-colored clothes to avoid exposure to the sun. After sun exposure, the use of special flexible shampoo with the functions of moistening hair and supplementing oil in time can also reduce the degree of hair damage.

Apply anti-ultraviolet hair gel and hair cream before swimming, and then wear a swimming cap, which can reduce the adverse effects of sunlight on hair color and quality. Rinse your hair thoroughly with clear water after swimming to remove the salt and oxygen residues in hair loss, and use nourishing shampoo and conditioner to wash your hair, replenish moisture and nutrition in time, tighten the fur layer of your hair, and help your hair restore health and luster.

After being sunburned or damaged, hair is easy to lose its luster. Here are some tips to brighten hair:

1. When washing hair, add a small amount of protein into shampoo, and gently massage the scalp. After washing, mix the egg yolk with a small amount of vinegar, slowly smear it along the hair, wrap it in a towel for 1 hour, and then clean it with clear water, which will make it black for dry and hard hair.

2. After washing your hair, add 1/3 of the hair oil you usually apply to clean water, completely immerse your hair, and then use a dry towel to absorb water after soaking, which will make your hair bright and smooth.

3. Washing your hair with shampoo and then washing it with tea can remove excess dirt and make your hair black, soft and shiny.
