Worse than before
I was so excited to use Nailkale. I've seen it on several round-up lists as being one of the best products for splitting/peeling nails. I did notice that it hardened nicely and looked smooth. Unfortunately, within a week my nails were peeling and splitting worse than before. I continued use for another month with the hope they'd get better, but they only got worse. It's taken me six months to grow out the damage. Back to OPI Nail Envy for me.
