Weird nail issue (pic) - ridges on thumbs

I've had this issue for as long as I remember. I have it on both nails of my thumb. It's never caused any problems but anyone know what it is and how to treat it?

The type of disorder in your nail looks to me like it was caused by some type of injury to the matrix of the nail. The white half-moon you can see at the cuticle of the nail is the leading edge of the matrix which is where the nail plate cells are born. If this area receives an injury, it can be seen in the emerging nail as permanent damage. Since you say you have had this for many years, it could possibly have been a 'childhood' injury.

The nail plate will always grow in this manner as there is nothing you can do to change the way the matrix produces nail plate cells.

I have also seen this in clients with a 'nervous tic' habit of 'scratching' at the cuticle line, which damages the cells as well.

You say you have it on both thumbnails, so it's unlikely to be from an injury. Also, running down the middle of the nail, and extending out even further at the tip of the nail, is a yellowish looking strip, almost like a fungal or bacterial type infection. Have you seen a doctor about this?

This is the first time I have heard anyone else having this same problem as me. I was pregnant in 2001 when I started to notice my thumb nails growing different. They were Horizontal grooves or wavelike patterns going throughout both thumbnails. They don't hurt but I have noticed that I have a hard time growing those nails out. My thumbs cuticles are always dry and are always pushed back. My guess is that my cuticles never sit onto my nail so my nails grow groovy. That is the only guess that I have. After having my daughter they are exactly the same horizontal grooves from the beginning. I hate it because when I wear nail polish those thumb nails look all bumpy and I hate that. I hope someone out there has some ideas to care for these nails of mine as well.
