Agreed - are you diffusing? I too need to get fluffy type curl formation and hopefully without frizz.
What products are you using? How are you putting them in? What is your whole routine??
After scrunching in my products, I diffuse dry on low. Now, I have not touched my hair at all during the drying process. Once dry, I'll VERY gently go underneath my hair with my fingers and shake out. I'll do one side and then the next and then the back. When I do the sides, I get the top too by leaning over to the side. If that made sense.
IF I need to do a bit more fluffing.... I'll put a tiny amount of pomade on my hands and rub onto my hands and fluff hair on the outside (not underneath). About 99.9% of the time, I'm frizz free. If I do anymore than that, I'll get frizz OR lose curl formation.
