ACV is drying for some, yes. It is also what protein sensitivity looks like. And AVG acts like protein. Also, the suave coconut has protein. Tresseme does not, but I am not sure on the L'Oreal stuff. Honestly, I would probably start there - the protein issue. Do you know your hair's properties?
remember, with all advice or suggestions for your hair, YMMV!!
My hair:
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
My routine:
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)

Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
