mnot really health but wondered if any manicure professionals could help me out ! My nails are usually pretty good but I have managed to split both thumbnails (making jewellery!) vertically. I've cut both very short inthe hope that the splits will grow out but they haven't as yet & keep catching them on things, so making it as bad again. Is there anything I could use to protect them whilst they grow (apart from false nails as I hate the idea of those !)
