These are other conditioners that used to be favorite combing conditioners of mine. I'd noticed the newer bottles with the mottled-swirly pattern had Sodium Hydroxide in them, but I was hoping that would stay with the newer products. Then one day an alert follower of the site asked me if the ingredients had changed on my recommended combing conditioners. And when I looked, indeed they had. First on one bottle, then the next favorite. There may still be a bottle or two that doesn't have it in there. If you find it buy it up as a combing conditioner. However, I'm thinking in time they will all have Sodium Hydroxide. When it's mixed with water, it becomes neutralized, so it's fine to rinse out. But I don't feel comfortable recommending you leave it on your hair as the leave-in product.

That, and I guess it's the principle of it. I vowed never to use a lye-type chemical in my hair again after all those years of partially dissolving my hair with relaxers, and here it pops up in my conditioner I'm using in my natural hair. I know it's in there as just a pH adjuster, but still. It bugs me a bit.
