How this protocol works

In plain language

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.
