【化】 natural light

1. 頭發(fā)的自然光澤來自它自身的護(hù)發(fā)素：油脂，它含有蠟和脂肪，還含有抗感染的自然抗菌劑。油脂含量過多會(huì)導(dǎo)致油性發(fā)質(zhì)，相反，油脂含量過少則會(huì)導(dǎo)致干性發(fā)質(zhì)。
   Hair's natural shine is supplied by its own conditioner, sebum, an oil composed of waxes and fats and also containing a natural antiseptic that helps fight infection. Too much sebum results in greasy hair and conversely, too little sebum makes dry hair.
