Does anyone know what’s up with my hair?

I was born male and I’ve been growing my hair out since about 2023. I’ve had it maintained and trimmed a bit since then and it’s currently around my shoulders.

It got wavy when it started growing, but the ends don’t look right. Most of it is thick and wavy and even a bit curly, but some tendrils (idk what to call them lol) look thin, frizzy and they aren’t curling together if that makes sense. I thought they were dead ends so I had them cut, but they’ve just come back. It looks awful and I hate it.

Is this heat damage? Is my hair just generally damaged? Should I change up my routine? I have a theory it has to do with my iron levels or some other nutrient, but I’d love some advice.

Thanks!
