Nail conditions
Medically reviewed by Mitchell J. Mandel, M.D., F.A.A.D., Board-Certified Dermatologist. Last reviewed .
Nails can show signs of infection, skin conditions and sometimes other health problems. Dermatologists are trained to diagnose and treat conditions of the nails as well as the skin and hair.
Common nail conditions we treat
- Nail fungus
- Nail psoriasis, with pitting, thickening or lifting
- Brittle, splitting or peeling nails
- Infections around the nail, called paronychia
- Ingrown toenails
- Dark streaks or spots under the nail
When to see us
Have a new dark streak in a nail checked, especially if it is widening, has blurry edges or the color spreads to the skin around the nail. In rare cases, this can be a sign of melanoma.
How we treat it
Treatment depends on the cause. It may include creams, oral medicines, injections, draining an infection or a nail biopsy. Nails grow slowly, so it can take months to see a healthy new nail grow in.
Where it is offered
Offered at all of our offices.
