Dry and itchy skin: what should you know?

Dry air, hot showers, frequent washing, harsh cleansers, and friction can strip surface oils and leave skin tight, flaky, or cracked. Atopic dermatitis and asteatotic eczema can cause recurring dryness and itch. Contact dermatitis follows exposure to an irritant or allergen. Psoriasis, lichen planus, hives, scabies, and a yeast infection have different patterns and may need targeted care.

Describe where the itch occurs, whether it is worse at night, and whether you see scale, plaques, rings, bumps, burrows, wheals, cracks, or oozing. New medicines, products, travel, and itching in close contacts can also help identify the cause.

Keep showers brief and lukewarm, use a gentle fragrance-free cleanser on areas that need it, and apply a plain moisturiser soon after patting dry. Wear soft fabrics, avoid scratching, and keep nails short. Stop products that sting or were introduced before the rash began.

Do not assume every itchy rash needs an antifungal, steroid, or antibiotic. Treatment depends on the pattern and site; a clinician can distinguish eczema, infection, scabies, hives, and psoriasis and advise the correct product.

Arrange medical advice for widespread, persistent, recurrent, or sleep-disrupting itch, or for skin that cracks and repeatedly bleeds. Seek urgent help for trouble breathing, swelling of the lips or tongue, faintness, rapidly spreading hives, fever with a painful rash, pus, or rapidly worsening redness. New widespread rash after a medicine needs prompt review.

Ask: Is this mainly dryness or a specific skin condition? Which ingredients should I avoid? How often should I moisturise? Could a medicine, product, infection, or household exposure be contributing? What changes require prompt review?
