I think this used to happend to me when I washed my hair. I think what is was just like Bailey422 said. I stripped all of the natural oils out and my salp reproduced a lot to make up for what I had lost. My hair used to get a lot greasier back when I washed my hair. That fact totally baffles my family that doesn't understand curlygirl.lol

Back on Cones,so now my routine is,wash with Deva No-Poo every other day or so. Occasionally use 365 sulfate free,maybe use low sulfate shampoo mixed with conditioner once every two weeks are longer. I condition with Aussie Moist or HEHH. I style with a little GF TN,and finish up with tons of GN Pure Clean Smoothing Cream. No frizz...slippy, happy hair.
