Home remedies for nail psoriasis

Nail psoriasis reflects inflammation in the nail matrix or nail bed. It may produce pits, grooves, colour change, thickening, lifting, or debris beneath the nail. The appearance can overlap with fungal infection or injury, so a discoloured nail is not automatically psoriasis. Nail growth is slow, meaning visible improvement may take time even after inflammation settles.

Keep nails short and file rough edges gently in one direction. Wear gloves for prolonged contact with water, detergents, soil, or chemicals, and dry hands and feet carefully afterward. Avoid biting, picking beneath the nail, cutting cuticles, artificial nails, and aggressive buffing. Apply a plain moisturiser to the nails and surrounding skin. Record changes with occasional photographs and ask a dermatologist whether an injectable steroid treatment or biologic therapy is suitable for the pattern and severity.

Book an appointment if nail changes spread, several nails become involved, the nail lifts, or daily tasks become difficult. Seek prompt care for increasing pain, warmth, swelling, pus, or a dark streak that changes or extends onto nearby skin. Joint stiffness, swollen fingers or toes, or persistent heel pain also deserve discussion because psoriasis can involve more than the nail.

Does this look like nail psoriasis or infection? Should the nail be tested? Which home products should I avoid, and would local injection or whole-body treatment help?
