This is my hair after I washed and dried it. I don't use shampoo but I use conditioner after I wash my hair I use flaxseed gel, which works good do define the curls.
I wash my hair like every three days because my scalp starts to itch if I don't wash it longer than that
So my problems are I always have lots of split ends even after I cut them I get new ones after a few days already. Also the day I washed my hair it looks good very defined and all second day is but on the second and third day I look like a hot mess because the curls aren't defined anymore and start to turn into one bush and like don't move individually anymore.
What could I do about that?
