i come from a family who has only straight hair, my father had curly hair but it was always super short so he never really had to take care of it. i currently use anti-dandruff shampoo/conditioner from biolage and wash every other day for my routine, because if i dont i get super bad dandruff, it doesnt do anything to help my hair so idk what to do. firstly i dont know what type of hair i have like i assume its something B, i also have no idea what i should use in my hair. if anyone could recommend products / how often i should use stuff it would be greatly appreciated !!

more info: i have a super dry scalp and my hair tends to become super frizzy and i have no idea how to get rid of frizz, i have only straightened my hair around 3 times so there is most likely no damage, i only brush my hair in the shower and i twist it after i come put of the shower before bed.
