I know some have a problem from just one use but I wanted to try K-Pak at least 2 times before giving my 2cents. I'm Coarse/Med-High porosity.
I didn't notice any ill effects, this is the only product that I have containing mineral oil and I don't plan to use it more then a couple times a month. I figured if RCC could use it without issues then I could to and our hair is similar in texture/porosity. I also Low Poo once a week or so through my length.
