Thanks for the replies. I was actually just in Target and saw the Black Soap line, but I thought they would be drying and was kind of scared away by them.
As for the Neutrogena T-Sal, I have actually gone through an entire bottle of that. I thought it had a sulfate in it. I did pick up another bottle, but it did dry my hair out. I will try the scalp only wash method you've mentioned and see if that improves my hair any. My dermatologist did not mention discontinuing conditioner use, so I've still been using the Tresemme Naturals.
I have never tried any DIY gels, but I will check out some of the videos from that YouTube channel.
As an aside, what is the difference between the three Tresemme Naturals conditioners? I thought there was only one, but in Target I saw three kinds. I have been using the Nourishing Moisture one, but there was also a volume one and a bottle with a black label and cap.
