I was going to ask a question on here, about yellow nails. But instead I did a yahoo search first...and I found a helpful tip (maybe you guys can tell me if it really works!)...that I thought I'd share... I had wondered why my nails sometimes look a little yellowed after taking off nail polish...and this was the answer I read: "Red, burgundy, and brown-based polishes contain dark pigments that can leave behind a yellow stain on nails, especially if you skip a protective base coat, says Mona Monaghan, senior vice president and general manager of Sally Hansen Group. To lighten your nasty-looking nails, pour three capfuls of hydrogen peroxide into one-third cup of water and soak your fingers for two minutes. Then dip a toothbrush into the solution and brush your talons for a superclean finish. Next, massage both cuticles and nails with a cuticle oil that contains vitamin E. Wait two minutes, then completely remove the oil with a nonacetone polish remover. Prevent those unsightly stains from recurring by applying a moisture-locking base coat before you paint your pointers again. Try Sally Hansen Teflon Tuff Base & Top Coat, $3.49." Problem is, I last used a pinkish beige color! But maybe the same thing could happen? I don't know. Anyway, I always skip the "base coat" application, because I figure...it's just another layer that I have to wait to dry! But it seems that it's actually worth applying to your nails!
