發(fā)質的類型由頭發(fā)的天然狀態(tài)決定，即由身體產生的皮脂量決定，不同的發(fā)質有不同的特性，那么應該如何判斷自己屬于何種發(fā)質呢？
1、中性發(fā)質：如果頭發(fā)不油膩，不干燥，那么這種頭發(fā)屬于中性發(fā)質，是光澤、柔順、健康的發(fā)質。軟硬適度，油脂分泌正常，只有少量頭皮屑。
If the hair is not greasy, not dry, then the hair is neutral hair is shiny, supple, healthy hair. Softness and hardness, oil secretion to normal, only a small amount of dandruff.
2、干性發(fā)質：如果頭發(fā)無光澤、干燥、容易打結，特別是在浸潤的情況下難于梳理，且通常頭發(fā)根部頗稠密，但至發(fā)梢則變的稀薄，有時發(fā)梢還開叉，那么這種頭發(fā)屬于干性發(fā)質。干性發(fā)質是由皮脂分泌不足或者頭發(fā)角蛋白缺乏水分，經常漂染或用過熱溫度洗發(fā)，天氣干燥等造成。
If the hair dull and dry, easy to tie, in particular, is difficult in the case of infiltration comb and the hair root is usually quite dense, it tends to become thin to the tips, and sometimes hair has split ends, which are dry hair hair. Dry hair is a shortage or lack of hair keratin sebum secretion of water, often dyeing or shampoo with hot temperatures, dry weather and other causes.
3、油性發(fā)質：如果頭發(fā)細長、油膩、需要經常清潔，那么這種頭發(fā)是油性發(fā)質，缺乏光澤。由于皮脂分泌過多，而使頭發(fā)油膩，大多與荷爾蒙分泌紊亂、遺傳、精神壓力大、過度梳理以及經常進食高脂食物有關，這些因素可使油脂分泌增加。發(fā)絲細者，油性頭發(fā)的可能性較大，這是因為每一根細發(fā)的圓周較小，單位面積上的毛囊較多，皮脂腺同樣增多，故分泌皮脂也多。
If the hair is thin, greasy, require frequent cleaning, then the hair is oily hair, lack luster. Due to excessive secretion of sebum, leaving hair greasy, mostly related to hormonal disorders,genetic, mental stress, excessive combing and frequent consumption of high-fat foods, and these factors can increase oil secretion. Hair fine person, the larger the possibility of oily hair, this is because each of the smaller circumference of fine hair, the hair follicles per unit area is more, the same increase in the sebaceous glands, it is also more sebum secretion.
