What are the causes + 4 ways to treat
Vertical ridges, on the other hand, can occur for a multitude of reasons, not all of which are preventable. First point: aging. Unfortunately, these ridges might just be a byproduct of the natural aging process, especially if they are very subtle and seem to be persistent. It makes sense: our fingernails are vulnerable to the same harmful actors that cause our skin texture appears dimpled (things like sun exposure, loss of collagen, and oxidative stress).
Your tips can also experience your regular drought; if you notice that the edges of your nails are starting to split with these vertical lines, your fingernails might just be trying to tell you that they are dry. Like Amy Lin, the founder of Sundays– a wellness nail care brand with New York studios – explains, “Dry skin can cause ridges on your nails because it’s how your body tries to communicate with you. Especially if you tend to use drying products on these tips or wash your hands a lot (which can very well be all of us right now), you might start to see these grooves appear.
And because beauty always has an internal moment, these peaks could signify nutritional imbalances as well. If you’ve recently embarked on a new diet, check with your fingernails – these divots could be important signs that the new diet might not be working for your body. “Nails are made mostly of hardened protein,” says Lin. (Namely, a protein called keratin). “When we lack protein, calcium, or other vitamins, it can sometimes show up on your nails with vertical lines.” And at a similar pace, stress can also come into play: just as stress can lead to temporary hair loss, your fingernails can also become streaky and brittle, according to Lin.
