I've never had nice nails in my life - and I have a vertical split in one thumb-nail, the result I think of bashing it into a handrail without an end-cap in House of Fraser, talking to my DD instead of looking what I was doing! I've tried everything and they will get just over the end of my finger (or thumb) then they'll snap, or I'll get a split way down at one side, or something. I use a Leighton Denny crystal file, and have tried every treatment under the sun - at the mo it's Jessica oil and Nail Drink and hand cream several times a day, intensive sort at bedtime and cotton gloves - but I have never, and no doubt WILL never, have a set of nails that I can feel proud of! :sad:
