Introduction
In general, inflammation of the scalp with yellowish discharge may be caused by inadequate scalp hygiene, friction-induced scalp injury, folliculitis, secondary infection of seborrheic dermatitis, or scalp abscess. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition through general measures and medication under a doctor's guidance. In daily life, avoid frequent hair perming and dyeing to reduce irritation from chemicals on the scalp.
Under normal circumstances, inflammation of the scalp with yellow discharge may be caused by improper scalp hygiene, friction-induced scalp injury, folliculitis, secondary infection of seborrheic dermatitis, or scalp abscess. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through general care, medication, and other treatments. A detailed analysis is as follows:
1. Improper scalp cleaning: Long-term accumulation of oil and dirt on the scalp can clog hair follicles, leading to inflammation and yellow discharge. Use a mild, non-irritating medicated shampoo, wash hair 2–3 times per week, gently massage the scalp with fingertips (avoid scratching with nails), and dry the scalp thoroughly after washing to prevent bacterial growth in moist environments.
2. Friction-induced scalp injury: Wearing tight hats or brushing hair too vigorously may damage the scalp, leading to secondary infection, inflammation, and yellow discharge. Immediately stop wearing irritating hats; switch to loose, breathable cotton hats. When combing, use a comb with rounded tips and gentle motions. Clean injured areas gently with normal saline.
3. Scalp folliculitis: Infection of hair follicles by *Staphylococcus aureus* causes inflammatory red papules. When these rupture, they release yellow pus. Patients should apply topical medications such as mupirocin ointment, fusidic acid cream, or compound polymyxin B ointment as directed by a physician. Avoid squeezing the lesions to prevent spreading the infection.
4. Secondary infection of seborrheic dermatitis: Excessive sebum production triggers dermatitis; scratching causes skin breaks and subsequent bacterial infection, resulting in erythema and exudation. Patients may use antifungal shampoos such as ketoconazole or selenium sulfide, and oral antibiotics like cefaclor capsules as prescribed. Reduce intake of high-fat and high-sugar foods to help control sebum secretion.
5. Scalp abscess: Inflammation spreads and forms a localized abscess, which softens centrally and becomes fluctuant. After rupture, it discharges large amounts of yellow pus accompanied by significant pain. Once mature, the abscess requires incision and drainage surgery to remove pus and promote healing.
In daily life, avoid frequent perming or dyeing of hair to reduce chemical irritation to the scalp. Maintain a regular sleep schedule and avoid staying up late, which can weaken immunity. Eat more fresh fruits and vegetables to supplement vitamins, drink plenty of water to enhance metabolism, and support the resolution of scalp inflammation and skin repair.
