Causes of dry, itchy skin
- Contact dermatitis
Contact dermatitis is a skin condition caused by an allergic or irritant reaction to substances that come into contact with the skin. When a person with contact dermatitis comes into contact with an allergen or irritant, their immune system reacts, causing inflammation and irritation. This inflammation can lead to dry, itchy skin, often accompanied by redness, swelling, and sometimes blisters, according to dermatologist and cosmetician Dr. Sowmya M.
- Atopic eczema
Eczema is a skin condition that typically causes red, inflamed, scaly, or oozing patches of skin. Constant scratching can damage the skin's protective barrier, leading to a vicious cycle of dryness, itching, and inflammation, according to a study published in the Journal of the American Medical Association.
- Seborrheic dermatitis
Seborrheic dermatitis is a skin condition characterized by red, scaly patches of skin that cause excessive flaking and dryness due to seborrheic dermatitis, leading to severe itching and discomfort.
- Psoriasis
Psoriasis is a chronic autoimmune condition that causes the skin to grow too quickly, leading to the buildup of thick, scaly patches. These patches can be itchy, painful, and disrupt the skin’s natural barrier, leading to dryness and irritation, says Dr. Sowmya.
- Environmental factors
Environmental factors play a major role in causing dry, itchy skin. Cold, dry climates can contribute significantly to dry skin. Heating and air conditioning systems also dry out skin. Too much sun exposure can damage the skin’s protective barrier, leading to dryness and irritation, says dermatologist Dr. Nitu.
- Lifestyle factors
Bathing in hot water can strip your skin of its natural oils, leading to dry skin. Using harsh soaps and detergents can irritate your skin and strip it of essential moisture. Certain medications, such as diuretics, corticosteroids, and retinoids, can also cause dry skin as a side effect, says Dr. Nitu.
