I might have to try the GF stuff.

Magnesium sulfate works really well for me, which is in Jessicurl stuff, among others. I've heard some say it's drying for them, but I've never had this problem with it.

I have used other products which encourage clumping in my hair, and therefore sort of indirectly enhance my curls [Re:Coil, Boots]. But for actual increased curl creation, it's Jessicurl for me.
