Thanks again for more help!
I started using the colorful neutral protein filler, once each week, but maybe I can put a few drops in my products or conditioner or something?

I'll try YT cucumber!

My hair is 2a/fine/thin density/normal porosity/likes protein (as far as i know), color treated once (went darker not lighter, not that it matters much, but no bleach) I'm living in San Francisco, so normal range dew points (dew point was 60 today). My hair cant hold any weight.
