I use salon series quidad Mediterranean Bay leaf exfoliating hair and scalp treatment... wow that's long lol. I purchased it from sephora, but it last forever I'll check my past purchases to let you know just how long. I have a third left. It's great on my relaxed hair but during my stretch I put a tiny amount in a applicator bottle and mix with water so it can spread easier. Also there are lots of recipes for scalp scrubs on pinterest.
I use this to help refresh/clean my scalp kinda like cowashing but my length hates that. Crystal clear scalp and it rarely itches these days.
Hth
Ps: how is your relaxed hair coming along? I remember you were concerned with low porosity, I think. What moisturizer do you use if your don't mind? I'm on the hunt.
