染发经验大总结 (2)

(有点健忘了,本来想很快就写出来续集,结果昨天才想起来,第一集在这里。)


1. 发质好染发: 一根头发外层是像瓦片一样排列的鳞片。直发的鳞片排列的比卷发更密更整齐,所以亚洲人发质普遍都比较好。永久染发剂染发时有两个过程,第一是让鳞片张开并去除原有的色素分子;第二是把新的色素分子引入到鳞片里(非永久染发剂没有去除原有色素分子的功能,而且色素分子比永久性的大,所以容易洗掉而且不能把头发染成浅色)。这两个过程中鳞片难免会出现丢失或重新排列不齐的现象(头发就这样损伤了)。密集而整齐的鳞片很难张开,这就是为什么很多亚洲人染发效果不好。Sally’s Beauty Supplies 有卖L’Oreal Hi-Color,是专门给深色头发的人染浅发用的


2. 染损伤的头发: 头发损伤的人有正好相反的问题。损伤的头发染色很容易,但褪色更容易。经常染发后洗一次颜色就全洗掉了。头发损伤不是非常严重的可以用非永久染发剂,大粒的色素分子比小粒的色素分子更容易嵌入在头发鳞片的缺口里洗不掉。如果头发损伤非常严重就需要一种产品叫 protein filler。Protein filler 的作用是坚固的补充在头发鳞片的缺口里避免色素分子脱落。


3. 去除以前的染发色:染成浅色的头发用深色掩盖一下就行了 (建议用非永久性染发剂避免损伤头发),但染成深色的头发想变浅很难。市场上有几种“漂白剂”,唯一一种不特别损伤头发的是 L’Oreal Color Zap 。如果是最近染的头发可以马上用热水和廉价香波(比漂白剂柔和多了)多洗几次头大部分染发剂就可以洗掉了。


4. 抠人染发用品:


漂染:喷瓶装一些双氧水,均匀的喷在头发上。用热夹板,卷发器,电吹风等加热头发。重复几次就有效。注意千万不要喷在皮肤上,弄完一定洗手。


鲜艳颜色:容器里挤1/2 cup 护发素,倒入2-3袋无糖 Kool-Aid (速溶人造色素人造香精饮料,黑樱桃口味效果最好,接近酒红色)拌匀。如果想让颜色鲜艳可以先用双氧水漂染。不漂染的话只有在光下才能看见颜色。带上胶皮手套,均匀的把拌好的护发素敷在头发上,不要接触头皮。弄完以后把头发盘在头上,包上塑料(可以用一个方便袋), >1个小时以后洗头,不要用香波。呆的时间越长颜色越鲜艳,
