I am getting my hair fully bleached but I am concerned about the damage. People who have experienced bleaching?

Well when I bleached my hair blonde it damaged my hair soooo much and i was a light brown color and never did anything to harm my hair and I couldn't take a shower or swim without it getting very knotted and tangled took about an hour to brush my hair out. So I had to strip my hair and dye it instead of bleach it. My suggestion is to just get it dyed rather than bleaching it.. But if you have your heart set on it just make sure you do it very carefully and take care of it(:
