Review of treatments for pseudofolliculitis barbae

Abstract

Pseudofolliculitis barbae (PFB) is a chronic inflammatory condition characterized by follicular and perifollicular papules and pustules primarily affecting the beard and neck area. PFB is a condition that predominantly affects patients with skin of colour. The objective of this paper is to review the epidemiology, pathogenesis and presentation of PFB, and assess the most recent evidence-based treatment options and recommendations for PFB. This is important to increase the quality of care given to target patient populations and to address the prominent disparity in healthcare management of patients with skin of colour. A literature review was conducted utilizing PubMed and Cochrane Library. The key term 'pseudofolliculitis barbae' was used. Search parameters were set to search from 1987 to the present. Results were further narrowed by limiting the literature review to published observational studies, case studies, case series, randomized control trials and case-control studies. Effective treatment for PFB requires a multifaceted approach that targets various aspects of the pathogenesis. Current treatments include preventive measures, antibiotics, corticosteroids, keratolytics, chemical depilatories and/or laser treatments. Topical therapies are currently the mainstay treatment. However, laser hair removal has become a potential long-term treatment option, and additional studies are warranted to understand its long-term efficacy and permanency.
