9 Nail Changes that Should be Seen by a Dermatologist

Color changing

Some nail color changes are innocuous, while others indicate illnesses, infections, anemia, or poisoning. Unexpected changes to blue, white/pale, greenish-black, yellow, or red might affect the whole nail or just portions of it.

A dark streak

Dark streaks on a fingernail or toenail could mean melanoma, so if you notice any, it s a good idea to get them checked out by a dermatologist right away as they re easier to treat when diagnosed early.

Nail lifting

It is important to see a dermatologist if a portion of the nail becomes detached and pulls away from the nail bed. This might be an indication of an infection, damage, or psoriasis, and it should be treated as soon as possible.

Redness and swelling

If the area surrounding your nail is red and swollen, it might be an indication that you have an infection, which is treatable if it is detected at an earlier stage.


It could be a sign of psoriasis, atopic dermatitis, or alopecia areata if your nails have holes that look like they were made by a small, pointed item. Going to a dermatologist can help fix these conditions.


If you smoke or wear red nail paint, your nails might be yellow, but it could also be a sign of rheumatoid arthritis or lung disease. If you can't figure out why your nails are turning yellow, you should see a doctor right away.


You should see a physician if your fingernails are bending down. Curvy nails could be a normal natural trait, or they could be a sign of a disease in the lungs, heart, liver, or stomach or intestines.

Grooves or gaps

If your nails have a deep, parallel groove, it means that your nail growth slowed down or stopped for a while. You should see a doctor or dermatologist about this so they can figure out what's wrong and treat it.

Ram s horn nails

If your nails get thick and grow out in the shape of a ram's horn, you might have a disease like psoriasis or ichthyosis. A podiatrist or dermatologist is needed to treat and take care of these.
