What Actually Works for Hair and Nail Problems Dr. Chris Adigun practices both general and cosmetic dermatology. We wanted to ask her about nail problems in particular because they are very common and she maintains a specialty in treating them. We asked her about the most common nail problems she sees, and she named simple onycholysis (pronounced Oh-nick-oh-LYE-sis). In this condition, the nail begins to lift away from the nail bed. You can identify it because the white area at the fingertip becomes much more extensive than usual. Usually, this is due to exposure to acids such as citrus juices or cleaning solutions. Having your hands in and out of irritants or even water (with or without soap) could lead to onycholysis. An overactive thyroid gland could also lead to onycholysis. To prevent it, try to avoid putting your hands into that sort of liquid. If you must do so, use gloves. And of course, a good hand cream to bolster the skin barrier is a very good idea. If these approaches don’t do the trick, especially if there are other symptoms, the doctor may want to test for thyroid function. Another common problem is allergic contact dermatitis. This could be caused by some of the same irritating substances responsible for onycholysis, but cosmetics are common culprits here. Nail polish and remover, especially nail polish remover, can cause nail problems for some people. If you are one of them, what actually works best might mean finding a less irritating product or, even better, leaving the nails unadorned. White Spots on Nails Many people have noticed white spots on their nails. We asked Dr. Adigun what causes these, and she replied that usually they are not worrisome. If you bang your fingertip, as you might if you slammed it in a door or a drawer, the trauma may show up several weeks later as a white spot. (More serious trauma could show up as a dark spot due to blood pooling under the nail; we discussed that with podiatrist Jane Anderson here,  but not with Dr. Adigun.) What About Ridges on the Nails? Nail ridges are very common, and the ones that run lengthwise along the same axis as the finger are due to aging. Just as our skin develops wrinkles, so do our nails. Consequently, there are no effective treatments. Nail ridges in children are a different story. They might show up as nails having the texture of sandpaper, or they could be horizontal ridges. Such nails should be seen by a physician, as they could signal an inflammatory condition called lichen planus or even an early sign of psoriasis. While we don’t have cures for these conditions, there are effective medications to manage them. Hangnails and Cuticle Problems Are you surprised that dermatologists have a fancy term to describe cuticle problems and other trouble affecting the skin around the nail? They call it paronychia (PEAR-oh-nick-ee-ya). If it is caused by an infection, it might be treated with an antimicrobial compound. The best preventative is not to pull, bite or clip off hangnails or rough spots in the cuticles, the skin near the nails. Instead, moisturize and possibly cover the spot with a bandage to remove the temptation while it softens and heals. Instant glue is another simple remedy t
