Scalp burns can be caused by hair bleaching with excess procedures such as unnecessary heating and excessive treatment with bleaching agents. The aim of this study was to investigate the morphological and histological changes of the hair and skin after bleaching. Ammonium persulfate and hydrogen peroxide (6% or 9%) solution mixed at a ratio of 1:2 (weight ratio) were sufficiently applied to human hairs and rat skin. ⋯ The rat skin bleached with 9% hydrogen peroxide exhibited epidermal thinning and subepidermal vesicle formation. The extracellular matrix of the skin was seriously disrupted after bleaching. Therefore, the use of only suitable bleaching procedures is suggested in order to avoid injuries.

Brachioradial pruritus (BRP) is a mysterious entity characterized by localized pruritus of the dorsolateral aspect of the arm. The precise etiology of BRP remains unknown, but sun exposure and/or cervical spine lesions seem to be triggering or at least aggravating factors. ⋯ Recently, gabapentin, an antiepileptic agent, has been reported to be an effective therapeutic agent in BRP. Herein, we report a 64-year-old man with BRP who showed good response to gabapentin therapy.
