Seborrheic Scalp – Symptoms and Treatment

Seborrheic dermatitis (seborrhea, seborrheic scalp) is a common scalp condition caused by overactive sebaceous glands and an imbalance in the scalp’s microbiome. It can lead to itching, flaking, and an oily scalp sensation.

Causes of seborrheic scalp:

Excess sebum and yeast overgrowth: Malassezia yeast thrives on sebum, causing inflammation and irritation.
Genetics: A tendency for an oily scalp and seborrheic conditions can be hereditary.
Hormonal changes: Puberty and stress can worsen symptoms.
Wrong hair care products: Harsh shampoos or overly heavy treatments can trigger flare-ups.

Symptoms of a seborrheic scalp:

Oily and quickly greasy scalp
Itching and irritation
Yellowish, sticky dandruff
Red, flaky patches along the hairline, eyebrows, and sides of the nose
Scalp imbalance: a mix of dryness and oiliness

How to treat seborrheic scalp:

Balancing shampoo – Use a gentle yet purifying shampoo that controls excess oil and soothes the scalp.
Regular exfoliation – A mild enzyme or mechanical exfoliation removes excess sebum and flakes.
Lightweight hydration – The scalp can be both oily and dry, so a lightweight serum can help restore balance.
Avoid overwashing – Washing too often can further stimulate sebum production.
Diet and lifestyle – Reducing sugar and dairy intake may help some individuals.
