Any advice/does anyone else struggle to maintain somewhat okay looking hair?

I went to a new stylist and got a balayage after not having any bleach on my hair for about 9 months (and even then it was minimal highlights/a partial balayage). Got my hair chopped to lessen the damage and this is what I’m left with about a month later and I’m so discouraged. This is blow dried with a light oil mist to try to lessen the frizz. My hair will somewhat curl if left to air dry.

Does anyone have advice? I try to avoid heat, use heat protectant, use olaplex shampoo sometimes, have pureology shampoo and conditioner, use olaplex no. 3, an argan deep conditioning mask… My fingernails grow incredibly well but my hair just refuses to be healthy.
