I have been dyeing my hair hazelnut blonde for two years using another brand but the color fades too quickly. I saw Tints of Nature at a local health food store and decided to try it. I bought the 6N Natural Dark Blonde formula which looked similar in color to my old brand. Even though my old color had faded to a medium blonde, this product dyed my hair DARK BROWN to almost BLACK. The conditioner was thick and lumpy, and not sufficient even to cover my fairly short hair. Maybe I purchased outdated product? To make matters worse, by the time I used the charcoal shampoo and the after-coloring shampoo (shampooing twice each time according to directions), my scalp was very dry and itchy even though I had no reaction to the skin test. The color does seem to be reasonably resistant to fading as I have been using non-color safe shampoo for several washes to lighten the color and it is still darker than I wanted. With my old brand I could color twice with one box. The Tints of Nature is a smaller amount, so there is too much for one application but not enough for two. I probably won't try Tints of Nature again.
