After a lot of research, I did find that there is a small, rare possibility that those ridges can mean an underlying medical condition or possibly even nail trauma, but for most of us, it’s completely normal as we age to see them getting more noticeable, especially if you have dry skin or skin conditions such as eczema.
The best way to help lessen the appearance of those lines in the first place is to make sure you are moisturizing your hands and fingers throughout the day with a thick cream, oil or petroleum jelly, paying special attention to your cuticles. Basically, treat your nails like you would your wrinkles!
