Thank you for both of your replies.
I've never heard of Auromere soap before, I'm going to go look that up now.
Alas, I think I am done with my shampoo bars for now. Hopefully, I can revisit them when my hair is in better shape. They seem to leave my hair dull-looking. Maybe I need to up my acv ratio.
Also, I have noticed a ton more halo frizz. Is it new growth or breakage? Can't tell. If it is breakage, I guess it could be from plopping, I think I started doing that about the same time I started using the poo bars. My hair is so fine and fragile!
