Dry And Itchy Skin: Causes, Treatment, And Prevention

Types And Causes Of Dry, Itchy Skin

Dry skin can happen to anyone at any age. It looks rough, scaly, or flaky. In some cases, it may lead to itching too. From the weather to the amount of moisture present in the skin, many reasons can lead to dry and itchy skin.

Dry skin may also lead to skin inflammations and rashes when scratched. This often leads to skin irritation or dermatitis. Let’s look at the most common causes of dry, itchy skin:

1. Contact Dermatitis

This condition is also called contact eczema. It develops when your skin comes in contact with an allergen, leading to an allergic reaction. Irritants like friction, occlusion, detergents, nickel, fragrance mix, chromium, shampoo, jewelry, hearing aids, and formaldehyde can cause contact dermatitis. Poison ivy is considered the most common cause of allergic contact dermatitis in the United States (1).

2. Atopic Eczema

This condition is a result of abnormalities in the epidermis and immune system. It leads to dry and itchy skin. People with atopic eczema have sensitive skin. Environmental factors, genetics, and food hypersensitivity may be the cause of atopic eczema (2). It most commonly occurs behind the ears or the area of the ear that meets the face.

3. Seborrheic Dermatitis

This condition occurs in areas with sebaceous glands that produce oil, including the ears. Usually, the lesions appear on the ears, face, scalp, upper chest, and back (3). The skin may turn red and crusty. This type of eczema in and around ears results in scaling, redness, and even crusty cracks.

4. Asteatotic Dermatitis

This condition results in dry and fissured skin. It occurs due to epidermal water loss (4). It appears mainly in the winter months due to dry conditions. It is also common in the elderly.

5. Athlete’s Foot

This fungal infection turn your feet dry and scaly. It is characterized by itching, flaking, and fissuring of the skin (5). The skin between the toes and all over the foot may turn soggy, red, dry, and white. Wearing occlusive (non-breathable) shoes for long periods can result in athlete’s foot. Even sharing washing facilities (like the showers at the gym) increases the risk of infection.
