My results were good with the Roux Porosity Control pH 4.5 Conditioner. I tried because I felt my hair was more porous than usual, and I wanted to see if the conditioner would close most of the cuticles, and it did. My hair was softer and had less tangles. I followed with a leave-in afterward since I have very dry hair.
I have since found two conditioners that I use as DT that give me the same result, so I'm using them instead.
I would recommend this product for natural curlies if you have hard water or overly porous hair (leave in for twice the time mentioned on the bottle). But be sure to follow with a leave-in.
Mod CG-Naturally Highly Porous and Dry
This list is not exhaustive...
Pre-treatment: Creamed Coconut

*experimenting and loving it!
The two conditioners that give me the same results are:
Aquage Healing Conditioner and Mixed Chicks Deep Conditioner. I've also used Ion anti-frizz solutions Extreme Moisture Nurturing Creme (Sally's) with the same results. I use heat with the products, and then let my hair cool down. The whole process takes 45 minutes.
