Itching, flaking, and crusting of the scalp can be caused by various factors. Some common causes of these symptoms include:

• Dandruff: a common scalp condition that can cause itching, flaking, and crusting of the scalp. It is often caused by an overgrowth of yeast on the scalp, and it can be treated with medicated shampoos.

• Scalp Psoriasis: Psoriasis is a chronic autoimmune condition that can affect the skin and scalp. Scalp psoriasis can cause red, scaly patches on the scalp, along with itching, flaking, and crusting.

• Seborrheic Dermatitis: Seborrheic dermatitis is a common scalp condition that can cause itching, flaking, and crusting. It is often caused by an overgrowth of yeast on the scalp, and it can be treated with medicated shampoos and topical medications.

• Allergies: Allergic reactions to hair care products or other substances can cause itching, flaking, and scalp crusting. Common allergens include fragrances, preservatives, and hair dyes.

• Head Lice:  these are tiny insects that can infest the scalp and hair, leading to itching and irritation. They can also cause flaking and crusting of the scalp.

• Fungal Infections: Fungal infections of the scalp, such as ringworm, can cause itching, flaking, and crusting of the scalp. These infections can be treated with antifungal medications.

• Other skin conditions: such as eczema or contact dermatitis, can cause itching, flaking, and crusting of the scalp. These conditions can be treated with topical medications and other therapies.

Suppose you are experiencing itching, flaking, or crusting of the scalp. In that case, it is important to speak with a dermatologist to help evaluate the underlying cause of your symptoms and develop a treatment plan.

The scalp may experience uncomfortable sores, bumps, or blistering due to the following:

• Infection of the hair shafts (folliculitis) or the skin (such as impetigo).

• An allergic skin reaction (contact dermatitis).

• Viral infections, such as chickenpox and shingles.

•  Inflammatory skin conditions, such as acne.

• A cyst, such as an epidermal cyst.

• Skin cancer on the scalp can cause devastating damage to both skin cells and tissues, potentially even metastasising throughout the body. It often appears as a growth or mole, a change in a preexisting growth/mole, an open sore that won’t heal, or irritation of your skin’s appearance. Three common varieties include basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma- all of which could be life-threatening if left untreated.

• In the case of concern about hair loss or thinning, when did you last have what you consider a normal head of hair?

• Do you have a family history of hair loss?

•  What are your hair care habits, such as using hair dyes?

• Question for women: Are you using a hormonal birth control method?

• What non-prescription and prescription medicines, including vitamins, have you taken in the last 6 months?

• Have you had any recent illnesses or surgery?

• Do you have any skin disorders or chronic diseases?

• Have you been exposed to head lice or ringworm?

• Does anyone in your family have similar symptoms?
