I can't say enough good things about Natural Instincts Linen Medium Cool Blonde. There simply aren't enough ash shades on the market, and even colors rated as 'neutral' come out very brassy and fake-looking on my hair. Not this, though... no orange tones at all. It gives a beautiful, cool, pearly-looking blonde tone. It looks very natural, it blends grey well (although it doesn't completely cover them, but the areas of light and dark that show through give my hair more dimension and make it look more natural.) It's close enough to my natural hair color that I can go a long time without coloring without really visible regrowth (the only difference I really see is that the colored hair is shinier and reflects more light than the regrowth.) My only two caveats are that, unlike a cream product, this can be messy. I've wrecked more than one old t-shirt using this product. I also wish that there were more ash shades available... from past experience I've learned that if it doesn't say ash/cool on the box I will come out looking like a clown, but I would certainly try, say, a 'light ash blonde' color if there was one available. That said, this stuff is great and is the only color/shade I will use at this point. If it's discontinued at some point, I will probably just let myself go grey instead of switching to another shade!
