Here are products you can use to help your hair grow at top speed. They have everything for Afro America Women. I'm also a user of this line. Got my two little sisters to use this and they don't experience Breakage or dry dull hair and got 1 1/2 inches new growth in a month. They've got everything for our type of hair.

Sponge rollers come in different sizes to give a variety of curls.
I have curls. Use alot of conditioner and not so much shampoo. to make curls in ur hair wet it and put ur finger around a piece of ur hair and gently twist it. and u have loose ringlets.
