Causes of dry, scaly skin

Dry air, long hot showers, and harsh cleansers can strip the skin barrier and leave rough, tight scale. Eczema often brings itch and irritated patches, while psoriasis can produce thicker, well-defined scale. Seborrheic dermatitis tends to affect oilier areas such as the scalp, face, or chest. Ringworm may form an expanding scaly patch with a more active edge. Tinea versicolor can cause fine scale with lighter or darker patches, commonly on the trunk. These conditions can overlap in appearance, so location and examination matter.

Keep showers short and lukewarm, use a fragrance-free cleanser where needed, and apply an emollient soon after bathing while the skin is still slightly damp. Do not share towels or clothing when a fungal infection is possible. Avoid applying steroid or antifungal products to large areas without advice, particularly on the face. If plaques keep returning, a clinician can match treatment to the cause; options may include emollient therapy, topical antifungal treatment, or specialist treatment for psoriasis.

Arrange medical advice when scaling is widespread, painful, cracked, oozing, rapidly changing, or not settling with gentle care. Seek prompt help for facial or eye involvement, fever, or signs of infection such as warmth and pus. A review is also useful when colour change remains after scale improves, since pigment can take time to return.

Could this be eczema, psoriasis, seborrheic dermatitis, ringworm, or tinea versicolor? Which moisturizer and cleanser fit my skin? Would I need a skin scraping or a treatment aimed at fungus or inflammation?
