hair is dry and brittle - what treatment works?

[m0therofdragons]

I have had high lights for about a year then went pretty blond with bleach (at hairdresser). Didn't get used to it so after 4 months went back to brunette. Now my hair is brittle but I want to try to avoid cutting it. Anything I can use. So far I have 3 minute aussie hair conditioners but need something more intense.

Be been using coconut oil. I put it on dry then leave overnight and wash in the morning. It's also good to use a bit when styling after drying.

Kerastase - expensive products but worth it.
