It was awhile ago and you can read my posts about it. I do remember that I think I made it almost a week without washing. Then I starting washing every 3 days and I used vinegar/water 1/1 ratio to rinse of the grease in between. I was doing it because alot of hair was falling out. Recently I have been working out intensely and have been washing my hair every morning again. I use healthy paraben free shampoo. I still rinse with vinegar on occasion. I take hair vitamins. My hair seems to be stronger after the no washing phase. I don’t remember how many months that lastest. Since I gave up all artificial sweetners and sugar and I’ve gone organic my hair seems to returning to a fuller lusher state. I think it’s all about inside out and alot less washing. Also, since I’m washing my hair everyday now, I’m really gentle…one lather cool water to warm water and lots of conditioner seems to work. Good Luck!!!
