What Is Nail Fungus? And What Causes It?

Nail fungus is a common condition that begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper into your nail bed, the fungus may cause your nail to discolor, thicken, and crumble at the edge. But even after successful treatment, nail fungus often returns. Nail fungus can affect your fingernails but it's more common in toenails.

Nail fungus is caused by various fungal organisms (fungi). The most common is a type called dermatophyte. Yeast, bacteria, and molds can also cause nail infections.

Nail fungus is also called onychomycosis (on-ih-koh-my-KOH-sis). When fungus infects the areas between your toes and the skin of your feet, it's called athlete's foot (tinea pedis). Athlete's Foot can also spread to your toenails and cause nail fungus.

Are You at Risk of Developing Nail Fungus?

Factors that can increase your risk of developing nail fungus include:

  • Older age
  • Wearing shoes that make your feet sweat heavily
  • Having had athlete's foot in the past
  • Walking barefoot in damp public areas, such as swimming pools, gyms, and shower rooms
  • Having a minor skin or nail injury
  • Having a skin condition that affects the nails, such as psoriasis
  • Having diabetes, blood flow problems, or a weakened immune system

Identifying Nail Fungus

Whitish-yellowish or brownish discoloration of the nails is a sign of nail fungus

If your nails become brittle or change color, it might be caused by a fungal nail infection



  1. Wet the bar of soap and create a generous lather.  
  2. Wash thoroughly around nail beds and up and under around nails and fingers or toes.
  3. Use Naturasil Nail Fungus Medicated Soap* at least twice daily for 4-10 days.
  4. The nail will ultimately have to grow out for the fungus to be removed.

*Remove jewelry before use.
