Well I personally don't no of a website but when u go to your salon to get your hair retouched or wat ev jus ask em how. Or go to google and type in "how to take care of african american hair" and I'm sure ull find something. Usally the 1st thing result that pops up is the best 1. Anika hair striaghtner works very good on all sorts of hair. I gotta friend that has that kinda hair and it works 4 her, it looks pretty:) and I LOVE when people braid they're hair and leave the ends like not braided but curly. ITS SOOO PRETTY! :P
