I have been using Natural Jenesis Black Love Wash and it has black soap as the base. I love it! I get great results but this morning I watched Zipporah Beauty's channel on YT and she mentioned black soap has a very high ph of 9 and shampoos are not safe at that high level, which is I guess the reason why it is highly porious? I'm not all into that stuff, I do think it's important but I look at my results too. If my hair is in love, so am I!
