What should you know about brittle finger nails causes?

Frequent wetting and drying can strip oils from the nail plate, while detergents and solvents can make the surface more fragile. Biting, picking, manicures, filing in both directions and repeated impact may create splits. Eczema or psoriasis can affect the nail surface, and a fungal nail infection can present with thickening, colour change, crumbling or separation. A single altered nail may reflect local trauma; several nails changing together can point to an exposure, skin condition or a broader health issue. A brittle nail is a symptom, not a diagnosis.

Wear gloves with a cotton lining for wet housework, then dry hands and nails well. Apply hand cream or a nail moisturiser after washing, keep nails at a comfortable short length, and file gently in one direction. Do not pull off peeling layers or cut cuticles, which can injure the protective seal. Take a break from extensions, glue and harsh removers while the nail recovers. If nails are thick or discoloured, read about Nail Fungus and arrange an examination instead of masking the change.

Seek medical advice if changes persist, involve many nails, or come with pain, swelling, pus, bleeding or lifting from the nail bed. A new dark streak, a rapidly changing mark or pigment on the surrounding skin should be assessed promptly. Urgent care is appropriate for spreading redness, severe throbbing pain or fever.

Ask: Does this pattern suggest exposure, trauma, infection or a skin condition? Should a sample be tested? Could my manicure routine or medicines be contributing? What protection and follow-up should I use while the nail grows out?
