Treatment for Scalp Folliculitis

Initial Management

Gentle pH-neutral soaps and tepid water should be used for cleansing the affected area, pat the skin dry after showering, and wear loose-fitting clothing to reduce friction and moisture 1
Topical clindamycin 1% solution/gel should be applied twice daily for mild cases 2
Greasy creams in the affected area and manipulation of skin should be avoided to reduce risk of secondary infection 1

Oral tetracycline 500 mg twice daily for 4-12 weeks is recommended for widespread disease or cases with inadequate response to topical therapy 2
For suspected or confirmed Staphylococcus aureus infection with systemic symptoms, antibiotics active against MRSA may be necessary 1
Pseudomonas aeruginosa can cause folliculitis, and fluoroquinolones offer an effective oral treatment option 3

A 5-day decolonization regimen with intranasal mupirocin, daily chlorhexidine washes, and decontamination of personal items should be considered 1, 2
Culture recurrent lesions and treat with a 5-10 day course of an antibiotic active against the isolated pathogen 1
Combination therapy with oral clindamycin 300 mg twice daily plus rifampicin 600 mg once daily for 10 weeks can be considered for non-responders to tetracycline 2

Topical corticosteroids of mild to moderate potency can be used short-term to reduce inflammation 1, 2
For localized lesions at risk of scarring, intralesional corticosteroids can provide rapid improvement in inflammation and pain 2
Incision and drainage is recommended for large furuncles or abscesses 1

Topical acne medications should not be used without dermatologist supervision as they may irritate and worsen the condition 2
Prolonged use of topical steroids should be avoided as they may cause skin atrophy 1, 2
Folliculitis is a common side-effect of treatment with potent topical steroids, so monitor closely when using these agents 4
Differential diagnoses such as tinea capitis should not be missed, as it can present with diffuse pustular lesions resembling folliculitis 5

Laboratory investigations to confirm the diagnosis are advisable to isolate the causal organism and direct the choice of systemic therapy 5
