What are some tips for healthier hair & what are some good shampoos to help repair breakage & help it grow?

My hair has broken off pieces & it looks layered but its not, I try not to put it up in rubber bands too much & have swichted to those claw clips instead when I want my hair out of my face. I used to color my hair at home a few times a year (its blonde) & I think that is what helped to damage it. I blowdry my hair & I dont use a straightener very much at all. Im curious if there are any health hair tips to repair my locks?
