Tips for growing 4b/c Hair down to waist length

I have been trying to grow my 4b/c hair down to waist/butt length and I seem to be stuck at collarbone length. My hair is all natural, I usually do two strand twists, braids, or wear wigs over flat twists. I try to avoid using heat on my hair and keeping it moisturized with oil.

I use shea butter, sweet almond oil, hemp seed oil, caster oil and other oils to keep my hair moisturized. But it’s still gets dry very quickly especially in the winter.

I have been looking for a hair stylist that can do my hair consistently, but I don’t trust people with my hair (to many hair stylist have damaged my hair or skin previously/recently) so I been learning how to style my own hair, but it always ends up frizzy.

I’m allergic to coconut oil, pineapple, and sesame seeds - which has been limiting the products I can use in stores.
