Fingernail question

[daughtersrus]

I noticed the other day that line between the white part of my fingernail and the bed of the nail is not a sharp, crisp line but blurred. This is on my middle, ring and pinky finger on both hands. The pointer fingers and thumbs on both hands look normal.

I've read about bruising, anemia...but none of the pictures similar

My aunt has soft lines but mine are very sharp. I have long nails, so when I wash my hands I always run my fingernail underneath to keep them clean. Do you use anything to push the nailbed back under the nail? Maybe tgat would help give it a more solid line.
