Fungal Nail Infections
Fungal nail infections (onychomycosis) are one of the most common nail problems. They cause thickened, brittle, and discoloured nails, often starting in the toenails but sometimes affecting the fingernails. These infections can be persistent and difficult to treat with over-the-counter remedies. At DermLab, our Dermatologists provide accurate diagnosis and targeted treatments that work, including access to prescription medications and advanced options.
Why Diagnosis Matters
Not all thick or discoloured nails are caused by fungus. Psoriasis, trauma, or other nail disorders can look very similar. That’s why a Dermatologist diagnosis — often confirmed with a lab test — is essential before starting treatment.
