Shampoo strips your hair of natural oils that keep it healthy. Since bleached hair naturally has less oil, you should wash it less. Aim to shampoo your hair once per week if possible.  If shampooing once per week is not enough, try slowly cutting down to about 2-3 times per week instead.

Ask your stylist for a suggestion, or browse the options at your local drug store. A clarifying shampoo will also remove chlorine from your hair. Experiment with low-maintenance styling options. Let your hair air dry when it’s wet, and embrace your hair’s natural texture so you don’t have to use a curling iron or straightener.  Bleached hair is already brittle, and adding heat will make it more prone to breakage. If you must occasionally use heat for styling, spray your hair with a heat protectant and keep your styling tool on the lowest heat setting.
