Abstract : Pediculosis Capitis (PC) is a parasitic infestation of the hair and scalp caused by Pediculus Humanus Capitis (PHC). Risk factors for transmission include direct contact between the hair and scalp of patients and direct contact with fomites, such as using personal items together with individuals with PC. Alopecia is baldness or hair loss in areas where hair normally grows. A 40-year-old male complained of very annoying itching on the scalp and baldness in several locations of the head since 3 months ago. The patient only used anti-dandruff shampoo, but there was no improvement. Then he visited a general practitioner and was given zinc 20 mg tab 1x a day and vitamin B complex 1x daily, but there was still no improvement. Physical examination of the capitis region showed multiple alopecia patches, nits (+), and excoriation (+). A dermoscopic examination revealed several grey hairs, translucent and firmly attached to the hair shaft and found broken hair. On a 10% KOH examination, PHC eggs were found. The patient was diagnosed with pediculosis capitis with multiple alopecia patches. The management was given permethrin 5% cream twice with an interval of 1 week and cetirizine 10 mg once a day. The patient controlled 2 weeks after the beginning of treatment and the itching was greatly reduced. Dermoscopy and KOH examination found no PHC eggs or nymphs. Clinical symptoms of pruritus are caused by a delayed hypersensitivity reaction resulting from sensitization to lose salivary antigens or faecal antigens and generally occur about 2 to 6 weeks after exposure to PHC. Chronic scratching caused by inflammation associated with relatively prolonged pediculosis may result in hair loss. Treatment with permethrin 5% topical cream may be a PC therapy option that can eradicate PHC at all stages of life.
