People, especially women, want black and shiny hair. However, with time passing away, many women find that the hair has gradually lost its brilliance and been becoming yellow and dry. According to the research, it is important for women to protect the hair carefully when they are 30 years old. In order to help women protect their hair effectively, three pieces of advice are introduced here for women to take into consideration. 

The first advice is that women should not be too thin. According to the research, the hair is composed of hair squama and hair cortex. The former is on the surface of hair and the latter is at the center. The trace elements like protein, zinc, iron and copper are very important to the human hair. If the content of fat on the body surface is very low and the supply of protein and fat inside the human body is inadequate, the hair can easily fall off and lose brilliance. Therefore, if the body mass index of women is lower than 18.5, it is difficult for women to have brilliant hair. Therefore, women should not lose weight blindly, or the normal health of body including hair can be threatened. It is essential for women to maintain the balanced nutrition and keep their bodies healthy as far as possible.

The second advice is to prevent the hair from being get sunburnt. The experts say that the water contained in hair can be lost if the hair is always irradiated by the sunlight. Thus, hair can become dry. The ultraviolet rays in the sunlight can strongly decompose protein so as to cause the hair squama to become warped and fall off. Therefore, it is important to prevent the hair from getting sunburnt. Women can use water-base jelly to preotect the hair.

The third advice is to supplement vitamin B for the hair. If women find that the hair loss become serious, they should often eat the foods containing vitamin B, protein and omega-3 fatty acid. What’s more, women can also accelerate the healthy growth of their hair by supplementing vitamin H and zinc, a kind of trace element.

Three pieces of advice mentioned above can effectively help women grasp the skills of protecting their hair. Therefore, it is beneficial for women to follow these three pieces of advice so as to repair and protect their hair more effectively. Women should remember that to maintain the balanced nutrition is an important key to maintain the healthy growth of hair.
