The Main Causes of Scalp Itching

Dandruff and Seborrheic Dermatitis: The Usual Suspects

Dandruff—those pesky white flakes—often appear due to excess oil or overly harsh hair products. They cause an itchy, irritated scalp, and the more you scratch, the worse it gets.

Seborrheic dermatitis takes things further. It’s a chronic inflammation that causes red patches with thick, yellowish flakes. It doesn’t just affect the scalp—it can also show up on the eyebrows, behind the ears, and around the sides of the nose.

How to treat it:

• Use specialized shampoos containing ketoconazole, salicylic acid, or zinc pyrithione.
• If symptoms persist for more than two weeks, see a dermatologist for a tailored treatment.

Psoriasis: When the Body Attacks Itself

Scalp psoriasis is an autoimmune condition that causes thick, red, scaly patches. These plaques are itchy, and scratching them can lead to bleeding.

Effective treatments include:

• Topical corticosteroid lotions and medicated shampoos
• Oral medication for severe flare-ups
• Managing stress, which often worsens symptoms

Pityriasis: Dry, Scaly Patches

Less well-known, pityriasis rosea can also affect the scalp. It usually starts with one large dry patch followed by several smaller ones.

How to soothe it:

• Use soothing, hydrating lotions
• Avoid scratching to prevent further irritation
• In most cases, pityriasis resolves on its own within a few weeks

Fungal Infections: When Redness Lingers

Fungal infections like ringworm (tinea capitis) cause itching, redness, flaking, and sometimes patchy hair loss.
