Dry scalp is a common condition where the skin on the head becomes itchy and flaky due to a loss of moisture.

Dry Scalp

Dry scalp occurs when the skin on the head loses excessive moisture, leading to irritation and flaking. This condition can be uncomfortable and sometimes embarrassing due to visible flakes. The dryness can result from various factors, including hair care products, weather, age, and certain skin conditions. 

Possible Causes of Dry Scalp

Hair Care Products

Certain hair care products can strip the scalp of its natural oils, causing dryness and irritation. Ingredients in shampoos, conditioners, and styling products may provoke contact dermatitis, leading to an itchy and flaky scalp. It is essential to choose hair care products that are gentle and suited for sensitive skin to prevent this issue.

Weather Conditions

Environmental factors play a significant role in the health of the scalp. Low humidity levels and cold climates can dry out the skin, including the scalp. During winter, the combination of cold air outside and heated indoor environments can exacerbate scalp dryness.

Age

As people age, their skin tends to lose moisture more quickly. This natural aging process can contribute to a dry scalp. Maintaining proper hydration and using moisturizing hair products can help mitigate this effect.

Skin Conditions

Several skin conditions can lead to a dry scalp. Psoriasis is a chronic condition that accelerates the growth of skin cells, causing plaques of thick, scaly skin. Psoriasis can affect the scalp, leading to dryness and irritation. Treatment options include medicated shampoos, topical ointments, and light therapy, as recommended by dermatologists.

Tinea Capitis, also known as scalp ringworm, is a highly contagious fungal infection that can cause a dry, itchy scalp. It spreads through direct contact with infected people, animals, or contaminated objects. Oral antifungal medications and medicated shampoos are common treatments for this condition.

Actinic Keratosis (AK), caused by prolonged sun exposure, presents as rough, scaly patches on the skin, including the scalp. This condition is more prevalent in people with less hair coverage and those over 50. Dermatologists may recommend topical treatments, cryotherapy, or photodynamic therapy for managing AK.
