thanks for the info everyone. I just started using ACV rinses about 3mos ago in an effort to be more 'all natural', but i wasn't sure of the ratio to use. I use 1/4cup to 3/4 cup of water. I poo, then rinse, then i pour the ACV mixture over my head and let it sit for 1min, then i rinse and deep condition my head. Its amazing! When i am stretching, i can literally feel the bulk/frizz of my hair detangling. It makes my hair easy to detangle, i also believe it deep cleanses the hair so the conditioner can penetrate better. I notice that I do not get dandruff, itchy scalp or even product buildup on my scalp anymore. I can go like 3 weeks with a clean scalp, no flakes or nothing. I also use it on my face as a toner. It feels sooooo refreshing and it softens my skin. after i wash my face, i dab a few drops on a cotton ball, i wipe my face with it, then i apply my moisturizer. ME LIKEY!!!!
