What causes sticky fluid discharge from the scalp?

Under normal circumstances, sticky fluid discharge from the scalp may be caused by excessive sebum secretion, improper cleansing methods, seborrheic dermatitis, folliculitis, or scalp eczema. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. Specific analyses are as follows:

1. Excessive sebum secretion: During puberty or due to hormonal changes, sebaceous glands become overactive, producing excess oil that mixes with sweat, resulting in a sticky, fluid-like discharge. Use an oil-control, silicone-free shampoo, wash hair 2–3 times per week, avoid frequent perming or dyeing, and reduce dietary intake of high-fat and high-sugar foods.

2. Improper cleansing: Over-cleansing or using harsh shampoos can damage the scalp’s protective barrier, triggering reactive sebum production; inadequate cleansing leads to buildup of oil and dirt. Switch to a mild, nourishing shampoo, keep water temperature around 37°C when washing, gently massage the scalp, and avoid scratching with fingernails.

3. Seborrheic dermatitis: Associated with Malassezia infection and abnormal sebum metabolism, this condition often presents with scalp itching and light red patches. Patients should follow medical advice to use medicated shampoos such as ketoconazole, selenium sulfide, or coal tar preparations, and maintain a dry,清爽 scalp.

4. Folliculitis: Bacterial infection of hair follicles causes inflammation, with red papules forming at follicular openings. When ruptured, these lesions release sticky exudate. Patients should apply topical medications such as mupirocin ointment, fusidic acid cream, or compound polymyxin B ointment as directed, and avoid squeezing the papules.

5. Scalp eczema: Inflammation triggered by allergies or environmental irritants manifests as redness, blisters, and oozing of sticky fluid when blisters break, accompanied by intense itching. Patients may use corticosteroid creams such as hydrocortisone butyrate, desonide, or mometasone furoate under medical supervision, and avoid allergens like pollen and dust mites.

In daily life, choose loose, breathable cotton hats to prevent prolonged scalp sweating. Dry hair thoroughly after washing and avoid sleeping with wet hair. Consume more vitamin B-rich foods such as brown rice and nuts to help regulate scalp metabolism and maintain scalp health.
