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!
Low porosity, medium texture.

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