Hi! I noticed that many had problems with dry scalp...
There is something called no-poo, which is something I discovered for naturally curly hair. Basically, you wash your scalp with conditionner, instead of shampoo.  I alternate between shampooing and a conditionner cleanse. You massage your scalp all over with conditionner and rinse completely.
It's similar to removing makeup with a cleansing milk, and really works cause it keeps the moisture in your scalp/hair.
