OK, I've tried this so many times and had all kinds of results. I gave up many many times, and I think the first time I tried it was more than 2 years ago! I've finally got it!!! My big mistake was I was using to much of the borax liquid soap!
Here are my basic directions:
About 2 TBS Borax Powder in 1 quart jar of Water, for the Borax liquid soap. OK, My hair comes about to my shoulder blades and I use about 1-2 TBS of the liquid/water soap! I just pour it in my hand, rub my hands together as if I am lathering it, then rub it into all of my hair and scalp. Wash it out really well, then fill a different quart jar with water and 1/4 tsp of Vitamin C power (Ascorbic Acid) and rinse my hair slowly with it, making sure to get everything out. Then, rinse really well again with water. - I used to get confused about whether I should rinse out the ascorbic acid rinse! Any way, this has been working really well for me, and I'd just like to encourage you to try it. Everyones hair is different, and your water is different, so you may need more or less. Try different things!
The biggest improvements I've notices the times I've been using this soap instead of the normal shampoo and conditioner, is my skin is way healthier!
