I'm only about 4.5 months in, but I also had a fairly itchy scalp before dreading. Good to know things may be less itchy in my future.
I just did an acv rinse this morning and it feels like it got all of the baking soda residue out, yay!
I think I'll end up trying plain water and maybe occasional salt water if I haven't been in the ocean in a while. :)
