You know, I the whole time I was natural a few years ago, I had no idea what ACV was... I always saw it abbreviated and never thought to ask, because I thought it was some kind of powder ( don't ask) and I wasn't interested in that... of course not!
Anyway, I have added this to my hair care routine and I love it very much. It does a great job at clearing the residue off of my scalp. My scalp tends to get a layer of film, it doesnt seem flaky to me like dry scalp, but more dusty, and I see notice more when I take a fingernail and scratch my scalp... maybe it is dandruff I don't know.
So about every other week, after washing my hair, I will do my ACV rinse (about 3 part water and 1 part ACV) where I take two bowls, fill one with the mixture and pour it on my scalp, catching it in the other bowl in the sink. I will do this several times until it bores me (lol, maybe 8 times) then was my hair once more, with Dr. Bonner's peppermint castille soap for the smell and to pick up any left over residue. then afterwards I condition as usual. I never notice dryness from this, however feel free to check other forums and blogs, I have heard of other ladies saying too much ACV in the mix was a little drying.
Oh yeah..... Also!! ACV is very good with a lot of other things as well, such as balancing the skin's pH levels i.e. under your arms or down below, acne, etc. You can find more information here: http://www.homeremediesweb.com/apple_cider_vinegar_health_benefits.php . Its always interesting to discover more natural ways to take care of ourselves.
