Brittle nails and dry skin

Frequent handwashing, sanitiser, detergents, cold air, and low humidity can remove protective oils from the skin and nail surroundings. Cracked skin, itching, redness, or blisters may indicate hand eczema or contact dermatitis, especially after a new product or workplace exposure. A nail that becomes thick, crumbly, yellow, or detached may have a fungal infection; these changes are covered in [Nail Fungus](/conditions/nail-fungus/). Dry skin alone does not explain every nail change.

Use lukewarm water and a mild, fragrance-free cleanser. Apply a thick moisturiser immediately after washing and again before bed, working it over the fingertips, cuticles, and nail edges. Wear lined gloves for wet or chemical work, but replace damp gloves. Avoid cuticle cutting, nail picking, and fragranced products that sting. If inflammation continues, a clinician can identify the trigger and prescribe treatment suited to the skin rather than relying on moisturiser alone.

Seek an assessment if cracks bleed repeatedly, sleep is disturbed by itching, the rash spreads, or nail changes continue after irritants are reduced. Get prompt care for increasing warmth, swelling, pus, severe pain, or fever, which can signal infection. A new or changing dark streak in a nail also needs examination.

Ask whether this looks like eczema, contact dermatitis, infection, or another nail disorder; which cleanser and moisturiser to use; whether patch testing is relevant; and how to protect your hands at work.
