PTs can be overload for medium texture but I agree with the idea to try them in products, one by one. I find I get more volume from mousse & spray gel than heavier oil rich products, but I have fine thin hair too. Never hurts to try a variety of things though! I think your hair is pretty & yes I think 2c is right :-)
fine, thin, normal porosity. Non-CG, but I treat it with TLC. I can't co-wash more than 1x a week, & I have to use T-Gel in rotation due to scalp issues.
