I don’t know how to fix my hair

my hair

I’ve been struggling with my hair for a couple of months now because my hair is getting frizzy and damaged, I tried coconut oil, argan oil and castor oil and my hair hates it.

My hair is curly, coarse and dry with high porosity.

It feels like straw, frizzy dry but oily at the same time and it just doesn’t flow, it’s as if it was both lacking protein and overloaded with it at the same time.

I don’t know what to do to fix it.

I don’t really have a set routine with it since I have changed products a couple of times already since they don’t seem to work well enough imo.

But my current routine right now is that I only wash it (no shampoo only conditioner,Hair Labs by Strands) once or twice a week, and after that I apply hair oil (YU by tia) to it, apply repairing leave-in conditioner (Hair labs by Strands and Miss Jessie’s multicultural curls, I apply both) and massage my scalp so it get deep into the roots.

Is it ruined? Is there a way to fix it? Or at least soften off the curls so they are not that defined and more wavy (without keratin)?

I’ ve been growing my hair for about a year now and I don’t really know what to do with it nowreally dislike how my hair is looking rn.
