How It Works

Nail fungus (onychomycosis) is a fungal infection of the nails, most commonly affecting toenails. It causes thickened, discolored, brittle nails.

SYMPTOMS:

•Thickened nails

•Yellow, brown, or white discoloration

•Brittle, crumbly, or ragged edges

•Distorted shape

•Separation from nail bed

•Foul smell

RISK FACTORS:

•Age (more common over 60)

•Sweaty feet

•Walking barefoot in damp areas (pools, gyms)

•Minor skin/nail injury

•Diabetes

•Poor circulation

•Weakened immune system

•Athlete's foot

MEDICAL TREATMENT (most effective):

•Oral antifungals (terbinafine, itraconazole) - most effective

•Topical antifungals (efinaconazole, tavaborole) - milder cases

•Laser treatment - mixed evidence

•Nail removal - severe cases

PREVENTION:

•Keep feet clean and dry

•Wear breathable shoes

•Change socks daily

•Wear flip-flops in public showers/pools

•Don't share nail clippers

•Keep nails trimmed short

* Medical treatment is most effective.

* Tea tree oil may help as adjunct.

* Treatment takes months (nails grow slowly).

Expected timeline: Nail fungus treatment takes 6-12+ months due to slow nail growth. New healthy nail grows from base - complete replacement takes 12-18 months for toenails.
