I finally decided to give this trick a try...and I love it! I use all natural shampoo bars, and the most recent batch I got from Apple Valley Natural Soap Company suggests this, as well hearing it from some of my followers. It helps to strip away buildup and leaves your hair SUPER soft and shiny.
Use about 1 Tbsp per cup of water, then pour it over your hair and scalp every 3rd or 4th shampoo. Rub in gently and rinse. I was surprised how well it worked. The smell is not overbearing and fades quickly.
A couple of notes: 1. Close your mouth when you pour it! 2. Don't shave the day you do this (or shave afterwards)...as it ran down my leg, I felt the sting! (Although I did have too much vinegar in my solution this time around).
Anyone else try this!?
