One of the most harmful behaviors to hair quality is that the hair scales are still open after washing your hair. At this time, if the hair is combed too many times, it will cause obvious damage to the hair scales, and the hair quality will deteriorate in this way.
Don't blow the air conditioner when your hair is wet.
Hair will swell with heat and shrink with cold. I just washed my hair and it is swollen in hot shampoo. At this time, blowing cold air will shrink rapidly. Such a cold and hot stimulus will deform the elasticity of hair, make it difficult to return to the previous elastic state, and damage the hair quality.
Eat more black sesame seeds.
There is sufficient evidence that black sesame improves hair quality. Both Chinese medicine and western medicine believe that black sesame can increase the luster of hair, promote hair growth and regeneration, and also have the effects of dandruff removal, anti-drying and deep conditioning. The experimental results also confirmed that the black sesame extract can significantly increase the production of melanin in B 16 melanoma cells and promote the blackening of white hair. In short, this kind of food is of great help to improve hair quality!
4. a cup of soybean milk every day
Soymilk is also a particularly good food for hair! Soybean isoflavone in soybean is a rare phytoestrogen, which can slightly reduce the metabolic level of human androgen, and has a positive effect on preventing prostate diseases and reducing DHT content. As we all know, DHT is the killer of male hair loss. Soymilk is also rich in water-soluble vitamins and dietary fiber, which can reduce the secretion of head oil and resist aging. Soybean milk and black soybean milk are very good hair care foods, especially suitable for women.

Several reasons for poor hair quality:
1, just wet my hair with shampoo.
Many people pour shampoo on their heads as soon as their hair is soaked, but as everyone knows, they can't wash their hair clean at all. Before using shampoo, rinse hair and scalp with warm water for more than 1 min to remove 70% to 80% dirt. Then, pour the shampoo into the palm of your hand, add water to make foam, and then apply it to your hair, so that the foam is richer and you can wash your hair thoroughly.
2. The water temperature is overheated
Many girls know not to let the hair dryer overheat, but they don't care about the water temperature and think it's cool to wash their hair with extremely hot water. But the fact is that the disulfide bonds of hair will be hydrolyzed in hot water with high temperature, and the strength and elasticity of hair will be damaged. So don't let your hair be at an overheated temperature, including washing your hair with overheated water and drying your hair by heat.
3, braid, ponytail is too tight
Bright ponytails are a common hairstyle for models walking on the runway. Girls also like to wear a tall ponytail in their daily life. In fact, wearing a long braid or ponytail will cause scalp tension and lead to hair breakage. It is often easy to lead to traction alopecia. Therefore, the usual hairstyle can be changed more, mainly distributed.
4, the hot sun exposure
Hair exposed to the sun tends to become fragile, dry, rough and fragile. Especially when the hair is dyed with chemical products or light colors, it is easy to yellow, fade and appear dull after a long period of sun exposure. If it is black hair, it will turn red after sunburn. So it's best to wear a wide-brimmed hat or an umbrella when traveling in summer.
