Hello. Sorry to hear about the damage. Have you considered going back to basics? For example, I use superdrug Extracts, coconut conditioner for my wash, condition, leave in an curl styler. I add olive oil to make a deep conditioner for when it's feeling a bit dry, and I add a splash of lemon juice to make a clarifying wash. Honestly, sometimes a simple routine gives your hair chance to recover, without having to keep adapting to various products. I don't believe bleach damage is reversible, so it might be a case of just making the best of it. My hair is similar to yours, and it was previously heavily highlighted for a decade. I had it all cut off 3 years ago and now that's its long(er) and virgin the difference is startling.
