This is a picture of my thumb nail but it happens to my other nails too.
As soon as they are any length, they start to split low down and I have to cut them down really short again. The little white bit at the edge of the nail was almost invisible yesterday. By tomorrow it will be big enough to start catching on fabric.
I use a heavy moisturiser on them several times every day and I don't have to wash my hands more than normal for work or anything.
The split runs through the area where the nail is attached to my skin so it gets messy and painful. Any ideas of how I can prevent them?
