Expert-Backed Tips for Revitalizing Dystrophic Nails

LAS VEGAS — After antifungal therapy for fungal nail disease, some dystrophy may persist, which can be addressed by several available treatments. 

“With the fingernails, we don’t often see onychomycosis, but with toenails, we certainly do,” Tracey C. Vlahovic, DPM, a professor at the Samuel Merritt University College of Podiatric Medicine, Oakland, California, said at the Society of Dermatology Physician Associates (SDPA) 22nd Annual Fall Dermatology Conference. “But toenails are subject to a lot of forces beyond just fungal [infections]. We have the wear and tear of wearing shoes, gait, and other physical activity.”

For example, she continued, some runners develop second-toenail dystrophy “because there’s constant repetitive trauma to the toenail, and [poorly fitting] shoes can contribute to that. Biomechanical issues are a unique consideration when you’re dealing with toenail issues.”

Vlahovic highlighted several options that can help improve the appearance of dystrophic nails as they recover or grow back:

• Urea nail preparations: To temporarily soften the nail.
• Genadur (hydroxypropyl chitosan): This product “is used mainly for psoriatic nails, but I use it for all different kinds of nail dystrophy,” she said.
• DermaNail (acetyl mandelic acid solution): This can be used for brittle nails and fingernails. Vlahovic said she recommends it be used on toenails “in addition to the onychomycosis and other nail dystrophy treatments that I’m doing because it really helps to hydrate the nail unit.”
• Kerasal Fungal Nail Renewal (ingredients include propylene glycol, urea, glycerin, and lactic acid): This product is used “for smoothing out the appearance of the nail,” she said.
• KeryFlex: Applied in an office setting, this resin-based product restores the appearance of an individual’s natural nails. “It comes in two colors [and] absorbs the shock of what is going on mechanically with the feet,” Vlahovic said. “So, if I’m treating a ballet dancer performing en pointe, or a soccer player, it’s something I can use to protect the nail, but also to make it cosmetically more acceptable.”
• NECPro: A nail reconstruction method that involves the use of a composite used mainly by podiatrists, it “helps you not only create a barrier, but to create a natural-looking color that matches your own nail color,” she said.

In Vlahovic’s experience, KeryFlex and NECPro last 6-8 weeks. “You can use nail polish on top of them if you’d like, but they’re basically cosmetic barriers to protect the nail unit,” she said.

Vlahovic has disclosed being a consultant and investigator for Ortho Dermatologics and Sagis Diagnostics.
