If it's just to test it out, buy an affordable option! It may or may not work for you. I am someone (I have SD, aka seborrheic dermatitis) that *needs* to wash with sulfates. I wish it were different and that I could go sulfate free and even CO-wash, but my scalp is not having it, and I prefer a healthy scalp and for my scalp to decide over what I want. You can't force these things.
