@Ogoma, I haven't tried yet to, yet. I Judy use the conditioner I made as a co-wash, or just use shampoo on my roots only. But your recipe looks good. I had also given thought to adding a bit of Castile soap to some conditionerLet me know how it turns out!

I will attempt it sometime in the new year and will keep you posted. If you try it before I do, please let me know.
