I have tried to do the all one length thang and I get triangle head. So I've gone back to a few layers. I get better curl definition - especially in the back/crown area - and less frizz.
No more PJ tendencies. Tigi Curls Rock Curl Amplifier is the best thing to make my curls rock all day! Next best are KCCC and Re:Coil +HE TT Gel.
