I used it, and saw immediatly that i had more frizz...used it again, like an idiot, and my frizz is crazy..I have a lot of reversion at my roots, genrally frizz all over...my hair is still very soft and all, but I def need a new BKT to get rid of the frizz...so in case you were looking for natural BKT safe products, this ain't it. Giovanni tea tree does have sodium chloride in it, you just have to google all of the ingredients because some of them are super difficult to read through...
