If you’ve never done it before, don’t do it. You can easily damage your hair if not done correctly. If you just have to, visit your stylist regarding this and ask about their opinion regarding the products you’re using. Do not bleach your already bleached ends, they might even break off.
Olaplex helps protect your hair from damage. Bleaching damages your hair to a greater degree so make sure to ask your hairstylist to use it.
Wash your hair less frequently. Your hair could use some natural oil build up after getting stripped from that after bleaching. The more you wash your hair, the drier would they get and the colour would wash out more as well. On top of that, if you use hot styling tools, they would not help your hair either.
Your damaged hair after bleach need extra care and love, not burning and frying with styling tools.
Use oils to give your hair the extra nourishment that they need. Argan oil, coconut oil and olive oil are fantastic for dry and damaged hair. Oil your hair once in a week before washing your hair. Don’t forget your serums and hair masks.
Dry hair are prone to entangling, be gentle when trying to untangle them. Use a wide-toothed comb. Do not brush wet hair and let them air-dry whenever possible.
