Fungal Nail Infections: What Causes Them, Who’s Affected, and How to Treat Them

Fungal nail infections, also known as onychomycosis, are incredibly common—yet often misunderstood. At Fixation Skincare and Laser Clinic, we know how frustrating and persistent fungal nail issues can be. The good news? With the right treatment and advice, you can restore healthy, clear nails.

In this blog, we’re breaking down what causes fungal nail infections, who’s most at risk, and how we treat them effectively.

What Is a Fungal Nail Infection?

A fungal nail infection occurs when fungi invade the nail bed, nail plate, or surrounding skin. These infections can affect both fingernails and toenails, but are far more common in the toes due to the warm, enclosed environment of footwear.

Signs of a fungal nail infection can include:

• Discolouration (yellow, white, or brown)

• Thickened or brittle nails

• Nails that lift or separate from the nail bed

• A distorted shape or texture

• Crumbly or rough edges

What Causes Fungal Nail Infections?

Fungal nail infections can develop for several reasons. The main contributing factors include:

1. Moisture and warmth
Tight or non-breathable footwear creates the perfect breeding ground for fungi to thrive.

2. Poor foot hygiene
Not drying your feet properly or wearing damp socks can increase the risk of infection.

3. Cross-contamination
Fungal infections can spread from person to person or from other fungal conditions, such as athlete’s foot.

4. Nail trauma
Cracks or damage to the nail can allow fungi to enter and multiply.

5. Frequent salon treatments
Regular use of gel or acrylic nails without proper breaks can weaken the natural nail and increase the risk.

6. Health conditions
People with diabetes, weakened immune systems, or circulation issues are more prone to fungal infections.

Who Is Most at Risk?

While anyone can develop a fungal nail infection, certain groups are more likely to experience them. These include:

• Adults over the age of 50

• Athletes or those who regularly use communal changing areas and swimming pools

• People with athlete’s foot

• Individuals who wear tight, enclosed footwear for long periods

• Those with underlying health conditions, such as diabetes

• Anyone with a history of nail damage or poor nail hygiene

Is It Contagious?

Yes - fungal nail infections can spread easily, particularly in shared spaces such as gyms, nail salons, and swimming pools. They can also spread from one nail to another, so early treatment is essential to stop the infection progressing.
