This is a personal (but not terribly invasive) question: Do you paint your fingernails? I go through phases of painting and not painting mine. Currently I'm in a pro-painting phase, and the clear base coat I'd been using had gotten old and gunky. That just won't do, so when I was in Kroger the other day I decided to check out the Sally Hansen display. And look what I found!
For a week now I've been using this Green Tea and Bamboo Nail Strengthener, and I like it a lot. It goes on neat and clean, dries fast and does indeed appear to be working on strengthening my nails. So if you want to "wear" your tea habit from (nail) tip to toe, this might be worth a look!
