Types of Nail Fungus and Treatment

Nail fungus isn’t just an inconvenience—it can affect your daily life, make you self-conscious, and even cause pain. So, if you’ve noticed thick, discolored nails or crumbling nail tips, it’s your cue to seek nail fungus treatment in Gilbert, Scottsdale, Chandler, Mesa, and Phoenix, Arizona. However, not all nail fungal infections are the same. Let’s break down the different types of nail fungus​ and explore which treatments work best.

Different Types of Fungal Nail Infections

Fungal nail infections come in different forms, and identifying the exact types of nail fungus with pictures or without them is key to successful treatment. Let’s explore them:

Distal Subungual Onychomycosis (DSO)

These types of nail fungus usually start at the tip of your nail and spread underneath. You may notice the nail turning yellow or brown, becoming thick, and eventually crumbling. The cause of this type is dermatophytes, specifically Trichophyton rubrum.

Treatment options:

• Oral antifungals, such as terbinafine or itraconazole, often provide the best results.
• Topical antifungals may work for mild cases, but they take longer.
• Routine nail trimming helps remove infected portions of the nail and enhances treatment.

White Superficial Onychomycosis (WSO)

These types of nail fungus affect the surface of the nail. You’ll see white, chalky spots that can spread and turn the nail powdery and brittle. It’s more common in toenails. The cause of this type is Trichophyton mentagrophytes or non-dermatophyte molds.

Treatment options:

• Topical antifungal solutions applied directly to the nail.
• Oral medications for widespread infections.
• Filing or scraping off damaged nail tissue before applying treatment can speed recovery.

Proximal Subungual Onychomycosis (PSO)

These types of nail fungus begin at the base of the nail, near the cuticle, and spread outward. It’s often a sign of an underlying health condition, such as a weakened immune system. The causes of this type are Dermatophytes or sometimes molds.

Treatment options:

• Oral antifungals are usually necessary due to the infection’s location under the nail.
• Laser treatment can be an option for stubborn infections.
• Address any underlying health issues to improve treatment success.

Candida Nail Infection (Yeast Onychomycosis)

These types of nail fungus affect fingernails more often than toenails. You may see swelling, redness, and separation of the nail from its bed. The nail often becomes yellow or brown and may thicken. The cause is Candida albicans yeast.

Treatment options:

• Antifungal creams or ointments work for mild cases.
• Oral antifungals may be needed for more severe infections.
• If the surrounding skin is inflamed, an antifungal and anti-inflammatory combination may help.

Endonyx Onychomycosis

This type directly invades the nail plate without causing thickening or detachment. It typically results in discoloration, usually white or yellow streaks, but the nail remains relatively intact. The causes are Dermatophytes or non-dermatophyte molds.

Treatment options:

• Oral antifungals are often necessary.
• Regular monitoring helps ensure the infection doesn’t spread or worsen.

What is the Most Common Type of Fungal Nail Infection?

Distal Subungual Onychomycosis (DSO) is the most common among the types of nail fungus. It affects over 60% of all people with fungal nail infections worldwide. Most cases begin with a slight discoloration at the nail’s edge and worsen over time if untreated. In addition, about 1 in 10 adults will experience onychomycosis at some point, and the risk increases with age.
