Something that I like to do for my hair once a year or so is a vinegar hair rinse. A vinegar hair rinse is a conditioning treatment suitable for hair that has not been chemically colored. Henna-colored hair is fine. A vinegar rinse helps to remove build up from shampoo and other hair care products, and helps smooth and slightly straighten the hair. I like the bounce that my hair gets from using my bar shampoos, but I recently gave my hair a treatment in between testing new shampoo bar formulas. It was a bit over due, the last time I did it was over 2 years ago. During that time I had been testing a few new shampoo bar formulas, so it was nice to have a fresh start. I suggested this treatment to a customer who was new to shampoo bars and was having trouble with the transition. She really liked the result and I have been meaning to share it. I hope if you try it you like the results. It is very simple:
Mix 2 Tablespoons of Vinegar (Apple Cider Vinegar is best) with 2 cups of warm water. Wet the hair completely in the shower, then pour the rinse completely through the hair. Allow it to sit on the hair for a couple minutes and then rinse with fresh water.
