yes, apple cider vinegar is great. It should be organic
and unpasteurized, which means buying it in the natural foods
store. I also use it on my skin and hair. I mix it with
filtered water in a spray bottle and just spray it on. Between
shampoos it keeps my hair fresh and healthy, and of course it can
also be used as a rinse after shampooing. And, the fruit acids
play a role in keeping skin clear and youthful.
