Nail Conditions

Also known as: fungal nails, brittle nails, ingrown nails

Thick, discoloured or painful nails, treated from the root cause, not the surface.

The short version

Thick, yellow, crumbling nails are usually fungus; pitted or discoloured nails often point to psoriasis or eczema. Dark streaks are usually benign, but always worth checking.

Nail fungus rarely clears with creams alone, so the right diagnosis first saves months of wasted treatment.

What it can look and feel like

  • Thickened, yellow or crumbling nails
  • White patches or surface pits
  • Nails lifting from the bed
  • Red, painful skin around the nail

Why it happens

  • Fungal infection, the most common cause
  • Psoriasis and eczema affecting nails
  • Bacteria from manicures or biting
  • Trauma and some illnesses

How we treat it

  • Nail sampling to confirm the cause
  • Oral antifungal courses with monitoring
  • Medicated lacquers and topicals
  • Minor procedures for ingrown nails
