Pseudofolliculitis barbae (PFB) is an inflammatory condition of the face with a clinical presentation of papules in the beard area with occasional pustules or hypertrophic scarring, all of which develop in response to shaving. Prevalent in African American men, a limited amount of data have been published on the shave outcomes as they relate to clinically measurable responses and patient satisfaction scoring. The primary purpose of this study is to evaluate the impact of a daily shaving regimen and advanced shaving products on exacerbation of lesions and symptoms in patients with PFB. Ninety African American men were randomized to 1 of 3 treatment groups shaving 2 to 3 times per week with standard products (control group), shaving daily with standard products (daily standard group) or shaving daily with advanced products (daily advanced). The number of pustules, papules, ingrown hairs, and investigator's assessment of severity and subjective symptoms of itching and burning/stinging were assessed at baseline, week 6, and week 12. The response to treatment was also assessed by the investigator and the subject at weeks 6 and 12. Secondary measures including questionnaires regarding baseline shave practices were also correlated with outcomes variables. There were no significant differences noted between the 3 groups for papule (P=.32) or pustule (P=.46) count for the 12-week study. However, there was a significant mean papule reduction from baseline detected for both the control and daily advanced groups. In addition, compared to baseline, there was a significant reduction in ingrown hairs for the control group, and a directional reduction in ingrown hairs for the daily advanced group. There were significant group differences between the control group and both daily shaving groups, with the control group seeing significantly fewer ingrown hairs (P=.005 for control vs daily standard group and P=.04 for control vs daily advanced group). There were no significant group differences among the 3 groups for investigator-graded severity (P=.43) and response to treatment (P=.51). There was a significant perceived improvement in the response to treatment (P=.007) and itching (P=.002) for the daily advanced group vs the control group.
