I know I've said it a gazillion times, but I really, really love DermOrganic's Intensive Hair Repair Masque
, it's got rice keratin and it is paraben and sulfate-free in addition to being vegan. I use it every time I shampoo my hair and it has helped my hair recover amazingly from bleaching.
I second this! Even better, you can find the salon sized bottles at TJ Maxx. Full price they're $20, which is $10 less than Ulta but sometimes they'll have them on clearance for $15 or even $10 if they've been there too long.
