I've been trying to grow out a badly split nail (index finger, dominant hand). I've tried polishes, serums, wraps, and another brand of semi cured gel nails, none of which have been really effective. The split didn't seal properly, and the nail kept snagging and splitting further. The previous brand of gel nails never stayed on for more than a few days. So I decided to try Personail Super Jellies, and I can't believe the difference: the gel stays in place, and I don't have to be careful with it....
