发型师的思维：大脑左半球和右半球在思维上有什么不同？如题 谢谢了

发角就是 后脑附近的头发向上剃 还有就是 耳朵前的头发向上剃
反正就是这两处地方剪得很短很短

My Hero
My hero she is, and she loves me, as all other mothers would their children. I remember the time when I was struck on my bed by severe illness, and she used to pick up the coursework for me, journeying from her workplace to school, from school to home. My tears nearly ran out of control when I saw bruises on her knees. She got thoses bruises when retrieving my homework. I feel regret for having said nothing to her; an adolescent sense of rebellion kept me silent. Perhaps to others my mother is merely an ordinary hairdresser and stylist, but she is of the most beautiful and elegent style in my mind.

I have a dream,dreaming to be an excellent woman hair dresser.

正好我是学化妆品的.
染发剂中不只是含有色素物质,还含有氧化、还原剂.染发过程其实是让头发和染发剂发生反应的过程,散发出的味道应该是苯的一些功能性衍生物.例如苯二胺等.氧化还原过程对头部皮肤伤害很大,使头皮变薄,更容易吸收有毒物质.所以有的人在染发、烫发后,会有轻度的头晕症状.
对人体的危害主要是考虑重金属离子,例如高含量的铅容易导致白血病.但是目前没有确切的证据.
其它具体的危害,你可以再查询一下相关的报道.详细介绍起来,还有很多.
