This is a beautiful avant garde updo from www.hairstyletwist.blogspot.com! However, you would not try to comb this hair. After all the hair pins and detachable hairpieces that can be removed are removed, then rinsing this hair until all the gels run clearly out would be the first step toward manipulating this hair. A wide tooth comb to detangle any trapped hair would be your next step. Then shampoo and condition as usual.
Pictured here is a broken stick. Imagine if your hair is hard and brittle. If you bend this stick, then it is going to break because it is not soft. The same principle applies to your hair strand. Soft hair strands can withstand manipulation. It is pliable.
If your hair is hard, specifically look for moisturizing conditioners. Please see other articles on this site for moisturizing conditioner options. If it is soft but breaking, then look for a protein/moisture combination.
