What it is

➝ Seborrheic dermatitis is a chronic inflammatory skin condition that primarily affects areas rich in oil glands, especially the scalp.

➝ It presents with dandruff, redness, itching, and greasy or flaky scales. In more severe cases, it can cause inflamed plaques and secondary infection.

➝ Scalp rotation therapy is a treatment strategy that involves alternating medicated shampoos and topical agents to prevent resistance, reduce irritation, and improve long-term control.

➝ This rotation approach ensures that multiple mechanisms (antifungal, anti-inflammatory, keratolytic) are used against the condition, improving treatment effectiveness.

Why it’s done

→ To control chronic relapses, since seborrheic dermatitis often comes back after treatment.

→ To prevent the tolerance effect that can happen if only one type of shampoo or agent is used long term.

→ To reduce fungal overgrowth (Malassezia yeast) while also addressing inflammation and scaling.

→ To improve patient compliance, as rotation provides flexibility and reduces the chance of irritation from any single product.

→ In Korea, scalp rotation is a common dermatology protocol, often combined with advanced scalp care and hair clinic services.

Alternatives

→ Single-agent therapy: Continuous use of ketoconazole, zinc pyrithione, or tar-based shampoos (effective but may lose impact over time).

→ Topical corticosteroids: Short-term use to control inflammation, though not for long-term maintenance.

→ Calcineurin inhibitors: Tacrolimus or pimecrolimus for steroid-sparing use in sensitive scalp areas.

→ Systemic therapies: Oral antifungals (itraconazole, fluconazole) or isotretinoin for severe, resistant cases.

→ Lifestyle measures: Stress reduction, good scalp hygiene, avoiding harsh hair products.

Preparation

→ Dermatologist confirms diagnosis and rules out mimicking conditions like psoriasis, tinea capitis, or contact dermatitis.

→ Patients are educated about the chronic nature of seborrheic dermatitis and the need for maintenance therapy.

→ Scalp assessment helps determine rotation frequency and product selection.

→ In Korea, dermatology clinics may use trichoscopy (scalp dermoscopy) for a detailed scalp evaluation before starting treatment.

How it’s Done

→ A rotation cycle typically includes:

• Antifungal shampoo (ketoconazole, ciclopirox) → reduces Malassezia yeast.
• Zinc pyrithione shampoo → antimicrobial and anti-inflammatory.
• Tar-based or salicylic acid shampoo → keratolytic, reduces scaling.
• Selenium sulfide shampoo → antifungal and anti-seborrheic.

→ Example rotation (weekly schedule):

• Day 1: Ketoconazole shampoo.
• Day 3: Zinc pyrithione shampoo.
• Day 5: Tar-based shampoo.
• Repeat cycle.

→ In flare-ups, topical corticosteroid lotions or foams may be added for 1–2 weeks, then tapered.

→ In Korea, dermatologists often integrate medicated shampoos with scalp spa treatments, such as deep cleansing, cooling therapy, or herbal scalp packs, to improve comfort and compliance.

Recovery

→ Symptom relief (less itching, flaking, redness) is often seen within 1–2 weeks.

→ Scalp rotation therapy helps maintain control and prevents frequent relapses.

→ Long-term patients report less severe flare-ups, easier management, and healthier scalp appearance.

→ With consistent use, the need for steroid rescue treatments decreases.

Complications

→ Scalp dryness or irritation from overuse of medicated shampoos.

→ Contact dermatitis to ingredients like tar or fragrance additives.

→ Steroid-related side effects (if overused): thinning skin, folliculitis.

→ With rotation, these risks are minimized because exposure to any one product is reduced.

Treatment Options in Korea

→ Korean dermatology clinics commonly use structured scalp rotation protocols, often personalized based on severity and scalp type.

→ Many hair and skin centers in Korea combine medical shampoos with scalp scaling treatments (professional exfoliation and cleansing).

→ Clinics frequently recommend adjunct K-beauty scalp products, such as soothing tonics with green tea, centella asiatica, or herbal extracts, to complement medicated rotation.

→ Patients often receive customized rotation schedules and follow-up visits to fine-tune the protocol.

→ For resistant cases, Korean dermatologists may add oral antifungal therapy or recommend low-dose isotretinoin for seborrhea control.

→ With Korea’s integrated approach, scalp rotation therapy is seen not just as medical treatment but also as part of comprehensive scalp and hair health management.
