1. You can pad the hair on the top of your head and roots, and you usually need a perm. Only perm the inner layer, outer layer or your hair. The effect is the same as not burning. The hair on the inner layer of the top of the head bulges after perming, and it doesn't look too sharp.

2. You can put your hair higher, so that the hair on it is shorter and more broken, and it will be fluffy after bulging, and it will not look too sharp.
