I agree with Viv; I'm a big fan of two strand twisting. I only wash my hair once a week.I spritz my hair lightly each night to add moisture(I use a 1:1 mixture of water and KMS daily treatment but use whatever works for you),and then I make about 12 to16 twists and undo them in the morning. Once undone I apply a 15 to 20 second blast of heat while pulling the curls downward. I find this stretches the curls.
I've heard a lot of good things about fantasia IC Hair Polisher ice pomade and tonight I'm trying it for the first time, so far I'm really liking the way it feels. I find it weighs the curls down really well while clumping them. I'll know for sure tomorrow when I undo the twists. I hope this helps. Just think long and hard about relaxing, because once it's done, there's no going back!
