You poor thing...a few years ago I went to the salon and highlighted my hair. Chunks broke off and fell out. I had hair that was an inch long in some spots and the rest was straight and frizzy. I couldn't comb it because more hair would break off. So I used a reconstructor and lots of deep conditioning. It was almost waist length and I ended up cutting a lot off. It is finally recovered but a lot shorter. The only thing that helped was time and lot of conditioner, avocado oil, no heat and gentle treatment. Good luck.
