I have 3b/3c hair, am Caucasian and I've been able to make the twist out work, though I have had mixed results based on big or small I make my twists. I really just use my same old leave in conditioners and gel when doing it.

I find that if I focus on making my hair smooth before twisting -- meaning taking a section if hair, smoothing the product on and perhaps even combing it through my hair -- I get less frizz when I take my twists out.
