Is there a way for ultra damaged hair to get back to health ? My hair is really dry !

So my hair is really messed up now, thanks to all the ironing, dying, and all the extentions i’ve done to it….... Is there any way for my hair to come back to it’s natural healthy way ? Will conditioning it everyday help ??

What about leaving olive oil or using eggs for the protein?

Does anyone know any natural remedie ? Or good beauty hair products that will restore it?

It’s dry to the point where it breaks off
