First post, so I hope I am doing this right!
I have noticed that when you trim your nails, the profile of the nail’s edge is pretty much squared off, but as the nail grows it seems to sharpen. Could this be due to simple wear and tear, do different layers of the nail grow at different rates, or is it something else?
For clarification, I am not talking about a top view of the nail. I am talking about the perspective of the end of the nail as viewed from the side.
