Instant purchase OK! I've lowered the price because the spa sold out. My recommended method is to first condition your hair with the treatment before wetting it, then rinse, and then shampoo and re-apply the treatment. I heard that applying the treatment to dry hair helps the color and moisturizing effects to penetrate better, so I've been doing that. I used it about 1-3 times a week, quite casually, but my hair was beautifully colored, and I didn't have any stray white hairs shining! Please give it a try!!
