头皮屑是怎样形成的?

作者: 编辑:admin

要清除头屑,先要认识头屑本质。头屑是头皮屑的简称,主要有两种形式,一种是分泌过多的皮脂和污秽尘埃等混在一起,干了以后就成了头皮屑;另一种就是头皮表层脱落的角质细胞。造成它的因素主要有:

细菌:如果头皮新陈代谢过快或细胞成熟过程不完全时,就会使角质堆积。此时,以头皮死细胞为生的糠秕孢子菌大量繁殖,造成角质剥落,雪花般的头皮屑也就产生了。

过多油脂:人体头皮分布的皮脂腺比面部的更多,分泌量更大,更值得你紧张。皮脂是头皮屑一个良好的培养基,头发不干净,油脂过多,是头皮屑产生的最得天独厚的环境,也是细菌、真菌生长的温床。

皮肤病患者:对于有些患湿疹、牛皮癣等皮肤病的人,头发上也比较容易产生头皮屑,而且这种头皮屑与一般细小的头皮屑不同,它是大块大块的。如果有类似情况的话就要检查一下是否有了某些皮肤病。

But one thing is for certain, the chance for diplomacy would not have occurred without strong voices against an immediate bombing campaign. If we had simply gone to war last week or the week before, as many advocated, we wouldn't be looking at a possible solution today."
