What Nail Psoriasis Looks Like—and Tips to Manage It
August 04, 2023
![More than 8 million Americans are living with psoriasis, an immune-mediated disease that affects the skin. It can appear anywhere on the body, including your ears, eyelids, lips, and even the nails on your hands and feet.
How Common Is Nail Psoriasis?
50%
of people living with psoriasis have nail involvement.
90%
of people living with psoriasis will experience nail psoriasis at some point or another.
And up to 90% of people living with psoriatic arthritis notice nail changes, as well.
Symptoms of Nail Psoriasis
Psoriasis typically presents as raised, scaly, silvery patches of skin. But it appears differently on the nails.
Symptoms of nail psoriasis:
Pitting
Crumbling
Thickening
Separation from the nail bed
Discoloration or “oil droplets”
Changes in shape or size
Buildup or blood under the nail
Diagnosing Nail Psoriasis
Nail symptoms may be one of the first clues leading to a diagnosis of psoriasis. However, sometimes nail psoriasis doesn’t show up until years after skin symptoms begin.
It’s more common in the fingernails than in the toenails.
It typically affects several nails at once.
Nail involvement can also be a sign of psoriatic arthritis,
a joint condition that affects around 30% of people who have psoriasis.
(Nail psoriasis can occur before or after joint pain begins.)
Nail psoriasis is commonly misdiagnosed as:
Onychomycosis (nail fungus)
Anemia
Thyroid issues
Deficiencies in biotin, calcium, protein, vitamin A, or zinc
If you notice nail changes, see your dermatologist for diagnosis and treatment. Consider also meeting with a specialist known as rheumatologist to evaluate for psoriatic arthritis.
Nail Psoriasis Treatment Options
Many treatments for psoriasis skin lesions also target nail involvement. These can include:
Phototherapy
Retinoids
Immunosuppressive drugs, like cyclosporine
Phosphodiesterase inhibitors, like apremilast
Traditional systemic drugs, like methotrexate
Newer, targeted systemic drugs, like biologics
These treatments are used primarily for nail psoriasis:
Corticosteroids (topicals or injections)
Calcipotriene or calcitriol
Topical retinoids like tretinoin or tazarotene
Laser therapy
Treating nail psoriasis can be tricky and take time because nails tend to grow slowly.
On average for most people, it can take up to 6 months to grow out fingernails and up to 12 months to grow out toenails.
Work with your doctor to find the right treatment (or combination of treatments) for you.
Lifestyle Tips
Nail psoriasis-related pain and tenderness can affect daily activities. These tips may help.
Keep Nails Short
Clip them regularly to prevent separation from the nail bed and to avoid buildup.
Don’t Bite Them
Biting your nails can lead to nail infection and skin injury, which may worsen psoriasis.
Be Careful at the Salon
A typical manicure involves pushing back or cutting the cuticles and removing buildup underneath the nail—both of which could lead to an infection and worsen symptoms. Applying artificial nails can also lead to separation.
Consider bringing your own tools to the salon to reduce the risk of contamination, and tell your nail technician how to be extra careful. Or care for your nails gently at home instead.
Wear Gloves
From washing dishes to gardening, wearing gloves when working with your hands can help limit the risk of infection and prevent unnecessary irritation and moisture that may worsen nail symptoms.
Wash Your Hands
Keeping your nails clean (and dry) may help prevent nail infections, like green nails or onychomycosis, that can develop in moist environments.
Moisturize Regularly
Apply an emollient such as petroleum jelly after washing your hands to hydrate the nails and surrounding skin.
Choose Proper Footwear
Shoes with the right fit should not cause friction on your toes. Always pair your shoes with clean, dry socks.
Stick with Treatment
Be sure to follow your treatment regimen as prescribed for best results, and check in with your dermatologist regularly to monitor how well it’s working.
