That's what I've been using and find it's workign great! I'm just concerned about burning my scalp due to the prolonged use, or causing a fungal infection to set in (I've read a few other folks say that has happened to them when they've used ACV for a long period of time).
I'm diluting it half and half with water and using it every other day, and using Ponds Cold Cream daily on my face, neck and back, both of which seem to be very helpful in smothering the wee beasties (or whatever this is).
I bought some of the shampoo from demodexsolutions.com and hope that ends up being helpful (plan to use it on the rest of my family, too).
