Molecules on a keratin
chain bond, or link to each other, and the kind of bond they form determines whether hair is curly or straight.
At the high melt temperatures in the injection molding press, when moisture is present, each available water molecule can cleave a main
chain bond, leading to significant reductions in molecular weight.
