Is it true that amino acids moisturize your skin and hair?
氨基酸滋潤皮膚和頭髮是真的嗎？
Skin has a natural moisturizing factor to prevent it from drying out and protect it from irritation. More than half of this natural moisturizing factor comes from amino acids and other related factors. Amino acids are important for moisturizing skin and also help to moisturize hair. Shampoos and treatments that are made with certain amino acids have been shown to promote moisture retention and make hair easier to brush.
