Any recs for regrowing my hair?

Heyy, so ive had a rollercoaster of a hair journey. My hair is 3b, i bleached it 3 times in about a year and dyed it too. Ive been growing it out and trying to get rid of all the damaged ends but scared of getting a big chop. Ive used deep conditioners, hot oil, protective styles, ect. Any advice on what to do to help my hair?
