What do you all use in your hair?

A year ago, I bleached the absolute shit out of my hair and toned it down to almost white. That was....not the best idea. My hair has always been dry but now it's like...break off if it's not wet dry.

I used to take really good care of my hair and it was down to my knees.....but since I cut it all off at 17 it's refused to grow past my shoulders. I am never sure what to use. I am interacial...and advice? I was doing twists for awhile because it really helped my hair grow back in after the bleach...but it's out for now because it's just so damned dry...

Editing to add: I am almost 40 now, I haven't...really done anything with my hair since the 17..
