Issue: Hair that is dry and has lost its luster 头发干燥并失去光泽
­
"Hair becomes dry when the cuticle starts to break down and the inner fiber is exposed," Dr. Mirmirani says. Excessive heat can cause this--especially heat applied to wet hair. She recommends air-drying your hair partially before blow drying, and using a daily conditioner. Remember that hair fiber with color is more prone to damage, so be extra cautious if you color-treat your hair.
马诺莫尼医生说：“当头发角质层开始破坏，内部纤维暴露的时候，头发就会变得干燥。”过度加热将导致这种情况发生，尤其是对湿发加热。她建议在用电吹风吹干头发之前，先采用自然风干，并且使用日常护发素。请记住，毛纤维的颜色更容易损坏，所以染发的时候要格外小心。
