Yep. The "average" head of Asian hair can withstand the highest temperatures. They have done stress tests with hair strands from "average" individuals from "each" ethnic group. The have found Black hair to be the weakest, caucasoid hair to vary widely but the average being somewhat durable, but the Asian hair samples held many more times the weight than any other hair. Of course, studies like this make several assumptions:
1) That all Asian hair is naturally bone straight, which of course we all know is not true.
2) That all Black people have the same type of hair, and that all Black hair is naturally kinky, which of course we all know is not true.
3) That all scalps produce the same amount of sebum to lubricate the hair, which of course we all know this is not true either.
When it comes down to strength though, many East Asians have the best end of the deal. Slightly thicker hairs, more lubricated strands, perfectly aligned straight glossy cuticles, longest growth phase, fastest growth during the growth phase.
In lace costume wigs for theatre, Asian or Indian Remy hair is preferred hands down over any other hair type, regardless of the final color, for the above reasons.
