how can I go natural for good

Okay so I’m a classic hated my curls as a kid and damaged the life out of my hair since 16. Currently I’m somewhere between 2c and 3a right now BUT I had blonde in my hair last year and fried a few peices completely to the scalp and now that I have about an inch of regrowth it’s clear I’m a true curly 3a just like when I was a kid. I’m mixed but I have soft fine hair. I want to start going natural but my hair is so damaged that some pieces don’t even curl at all anymore. Because of that + my fine hair I get the best results after diffusing (and usually have to take a hot iron to help some lifeless pieces curl) I’m in this bad cycle of using heat and it’s not helping anymore than blowing out and flat ironing! Im still doing blow outs like 4 days a week because it’s just faster and easier most days…

help meeee where do I start, how do I get out of this cycle of heat tools but feel good and look good with out shaving my head and starting all over… Right now getting my best results with oui shampoo and conditioner, I deep condition 2-3x a week, I use heat protectant, gel, medium hold mousse, and usually a denman brush before diffusing - in that order. with that amount of product I have to diffuse or it’s too heavy for my hair. I’d love to air dry but my curl pattern looks so bad air dried from the damage.

I really don’t have pictures i’m sorry I looked ha.
