Yellow Toenail Treatment: What's Causing It and How to Fix It

Not All Yellow Nails Are Fungus

Yellow toenails are alarming — but they're not always toenail fungus. Understanding the cause determines the treatment.

Cause 1: Toenail Fungus (Most Common)

Fungal infection is the most frequent cause of yellow toenails in adults. Signs it's fungus:

  • Yellowing started at the tip or side and spread inward
  • The nail is thickening or becoming brittle
  • There's debris under the nail
  • Other toes are starting to change color

Treatment: Daily application of an antifungal like CamoToe (which also conceals the discoloration) or prescription medication for severe cases.

Cause 2: Nail Polish Staining

Dark nail polishes can leave a yellow residue on the nail plate. This is cosmetic, not an infection.

Treatment: Buff the nail surface gently, apply a whitening base coat, and let the stain grow out (2-3 months for toenails).

Cause 3: Aging

Nails naturally yellow and thicken with age, especially after 50. Reduced blood flow and slower growth contribute.

Treatment: Regular trimming and filing. CamoToe can conceal age-related discoloration even without fungal infection.

Cause 4: Trauma or Injury

A stubbed toe or tight shoes can cause bruising under the nail that appears yellow or brown.

Treatment: Time. The damaged nail grows out in 6-12 months. Concealment with CamoToe in the meantime.

Cause 5: Medical Conditions

Rarely, yellow nails can indicate diabetes, thyroid issues, or lymphedema. If yellowing is accompanied by other symptoms, see a doctor.

When to See a Doctor

See a dermatologist if: the nail is painful, separating from the bed, you have diabetes, or the discoloration is spreading rapidly.

Conceal it today. Treat it over time.
