im mixed too half black half white. i use garnier fructis anti frizz serum (silk) and la bella lots of curls gel to style it. (if you do this before bed your roots will probably be more curly) when you mix the two, you get the hold of the gel but it wont be crunchy cuz of the silk i condition it everyday but only shampoo on sundays (if you do it more than once a week you risk drying your hair out and damaging it) hope this helps girl
oh and if you want your hair to grow "faster" you can use Mane 'n Tail shampoo and conditioner (get it at walmart in the pet section or go to a pet store they prolly have it)
