Psoriasis Nails
Psoriasis Nails occurs when psoriasis affects the nail matrix and bed, causing distinct changes. Key signs include pitting (small dents), onycholysis (nail separation), yellow-brown discoloration ("oil drop" spots), subungual hyperkeratosis (chalky buildup under nails), and crumbling nails.
Treatment focuses on managing inflammation and preventing damage:
Topical treatments: Corticosteroids or vitamin D analogs
Injections: Steroids directly into affected nails
Systemic medications: For severe cases (methotrexate, biologics)
Lifestyle care: Gentle nail trimming, moisturising, avoiding trauma
Since nail psoriasis often accompanies skin or joint psoriasis, early dermatologist consultation helps prevent permanent nail deformity.
