Right, this is a tip in the category “learn from my fail”. My beauty fail of 2012 was getting paint thinner on my hands. (More or less an ADHD moment! I figured it wouldn’t happen…)
Apart from thinning the paint, irritating the skin and quite effectively removing nail polish; it also thinned my fingernails. This was about 6 months ago and you can see the difference between healthy and desperately damaged nails. There is a palpable thickening where the healthy nail starts, and I have to keep my nails polished because the tips are so brittle it tears and keeps on snagging everything!
