Psoriasis is commonly known as a skin condition, but it can also affect the nails. In fact, up to 50% of people with psoriasis develop nail changes, and the risk is even higher in those with psoriatic arthritis. Nail psoriasis can impact appearance, daily activities, and quality of life if left untreated.
Common Signs of Nail Psoriasis
Nail psoriasis may affect one or several fingernails and toenails. Common changes include:
Small pits or dents on the nail surface (nail pitting)
Yellow-brown discoloration, often called the "oil drop" or "salmon patch" sign
Thickened nails
Crumbling or brittle nails
Separation of the nail from the nail bed (onycholysis)
White patches or streaks beneath the nail
Build-up of skin under the nail (subungual hyperkeratosis)
These changes are often mistaken for a fungal nail infection. A dermatologist can distinguish between the two and may recommend tests if needed.
How is Nail Psoriasis Treated?
Treatment depends on the severity of nail involvement and whether skin or joint psoriasis is also present. Options include:
Topical medications such as corticosteroids and vitamin D analogues
Intralesional steroid injections in selected cases
Oral medications for moderate to severe disease
Biologic therapies for extensive psoriasis or associated psoriatic arthritis
Since nails grow slowly, improvement may take 3–6 months or longer.
Nail Care Tips
Keep nails short, avoid trauma, wear gloves during household work, and avoid picking at the nails or cuticles. These simple measures can reduce worsening of nail disease.
Key Takeaway
Nail changes may be the first sign of psoriasis and should not be ignored. Early diagnosis and appropriate treatment can improve nail appearance, reduce discomfort, and prevent long-term damage.
