Suz, I think that you and I have similar coloring, and I have been waiting impatiently for my hair to whiten naturally! We Summer-type ash blondes tend not to be afraid of going gray--on us, it just looks silvery and blonder--but it is very difficult for hair dressers to understand that; their instinct is to "warm up" hair color for women of a certain age. Because my gray hair is awkwardly centered in a band along the top of my head, I've been having my hair highlighted for years. The highlights blend in with the darker ash and cooler silver gray for a very natural look for me. But every time I have the highlighting done, I must repeat, "No gold. No yellow. Paler, please, ash blonde." The last time I went to the hair dresser, he talked me into adding taupe lowlights for depth. It sounded reasonable, but the results felt brown and drab to me, and like you, I found my thoughts straying to . . . platinum. Not all-over platinum, but platinum highlights, fairly chunky ones (which is actually what I think Sharon Stone has--so gorgeous) that will again blend with my natural dark blonde and silver, but in a frostier way, avoiding yellow. If your hair is strong and bleaches quickly, as mine does, I think this could work for you, too, while avoiding that period of all-over color, which tends to be harsh and draining on Summers. I actually think that a few high-contast platinum streaks can look more sparkling and dramatic on us than either one-color or "woven" effects. Not sure I'm making myself at all clear about this, but I empathize and wish you luck!
