One of the most harmful behaviors to hair quality is that the hair scales are still open after washing 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 like this.

Don't blow the air conditioner with wet hair.

Hair will expand with heat and contract with cold. Just after washing hair, it is in an expanded state in hot shampoo. At this time, blowing cold air will shrink rapidly. With such a cold and hot stimulation, the elasticity of hair will be deformed, and it is difficult to return to its previous elastic state, and the hair quality will be damaged.

Step 3 eat more black sesame seeds

There is sufficient evidence for black sesame to improve hair quality. Both Chinese medicine and western medicine believe that black sesame can increase the luster of hair, promote hair growth and regrowth, and also have the effects of anti-dandruff, anti-dryness, deep regulation and so on. The experimental results also confirm that black sesame extract can significantly increase the melanin production in B 16 melanoma cells and promote the blackening of white hair. In short, this food is very helpful 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 male hormones, 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. Soybean milk 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, put shampoo on your hair as soon as it is soaked.

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 applying shampoo, rinse your 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 thoroughly wash your hair.

2. The water temperature is overheated

Many girls know not to overheat the hair dryer, but they don't care about the water temperature, and they think it's cool to wash their hair with extremely hot water. However, the fact is that the disulfide bond of hair will be hydrolyzed in hot water with higher 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 at overheated water temperature, hot hair drying, etc.

3, braid, ponytail is too tight

A bright ponytail is a common hairstyle for models walking on the runway. Girls also like to wear a tall ponytail in daily life. In fact, wearing a tight braid or ponytail for too long will cause scalp tension and lead to hair breakage. Often, it will easily lead to traction alopecia. Therefore, the usual hairstyle can be changed more, mainly distributed.

4, the hot sun exposure

Hair exposed to the sun easily becomes weak, dry, rough and brittle. Especially when the hair is dyed with chemical products or light color, it is easy to yellow, fade and look dull after being exposed to the sun for a long time. If it is black hair, it will turn red after "sunburn". Therefore, it is best to wear a wide-brimmed hat or an umbrella when traveling in summer.
