Nope! I drink Bragg's Raw ACV (the stuff with the 'mother' in it) every single day, and it has a lot of great health benefits and gives me a lot of energy! however, eating it won't have any effect on your hair, and if I sweat I don't smell any of it. The ACV treatment for you hair is when you actually wash with it? I believe that acts almost like a conditioner if i remember correctly when you use it with the baking soda, it pretty much makes your head feel like a 4th grader's volcano science project (10x more fun than regular shampoo in my opinion :P) and to be honest it makes my hair feel even cleaner and softer than normal shampoo ever did before i started dreading.
The oil and water mixture melanie rose was talking about also works wonders for the itchies!! good luck ^_^
