I dont' know if the ACV gets it out. It's supposed to in theory but I have terrible water so I can't seem to make that work for the A cone. I do use DevaCurl products and they have that cone in it also and I can get it out with the no poo. You can use a cocobetain product like for instance beauty without cruelty makes a shampoo with that as the cleanser, no sulfates. So technically it's CG.
I'd try the ACV and see first. I'll watch for pics, good luck!
2c/3a?
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
