The Gut and Skin Microbiome in Alopecia: Associations and Interventions.

Objective: This review examines the current literature on the gut-skin connection in alopecia and summarizes interventions that impact hair growth by modulation of the gut or skin microbiome.

Methods: PubMed searches were done to assess studies of the gut and skin microbiome and forms of alopecia including, alopecia areata (AA), androgenic alopecia (AGA), alopecia universalis (AU), central centrifugal cicatricial alopecia (CCCA) and lichen planopilaris (LPP). Filters were applied for human and animal studies.

Treatment of Frontal Fibrosing Alopecia in Black Patients: A Systematic Review.

Frontal fibrosing alopecia (FFA) is a progressive cicatricial alopecia that can affect patients with skin of color (SOC); however, patients with SOC often are underrepresented in clinical trials and scientific publications on FFA. To better understand the management of FFA in patients with SOC, we sought to assess the clinical evidence for the efficacy of FFA treatment modalities specifically in these patients. This systematic review discusses studies on FFA characteristics and treatment outcomes in Black patients.

An update on cosmetic procedures in people of color. Part 1: Scientific background, assessment, preprocedure preparation.

Increased life expectancy, focus on appearance, and readily available and accessible cosmetic procedures have served to drive an increase in the number of nonsurgical cosmetic procedures performed in the last 20 years. Demographic shifts in the United States, with increases in diverse populations that seek nonsurgical cosmetic procedures, have resulted in the need for a better understanding of cultural preferences as well as structural and biological differences in the skin of people of color (POC). Although many advances in the form of cosmeceuticals, cosmetics, and photoprotection have been made to address the aesthetic needs of and minimize complications in POC, nonsurgical cosmetic procedures are required to address common aesthetic concerns.

An update on cosmetic procedures in people of color. Part 2: Neuromodulators, soft tissue augmentation, chemexfoliating agents, and laser hair reduction.

Recent years have brought forth the undeniable practice gap in dermatology concerning knowledge and experience of cosmetic procedures in people of color (POC). A paucity in the literature regarding evidence-based recommendations for the management of POC undergoing cosmetic procedures and the rise of cosmetic procedures in dermatology serves as a call to action to provide education regarding differences in skin of color that may impact the cosmetic outcomes. To mitigate the current practice gap on the safety, use, and benefits of cosmetic procedures in POC, part 2 will discuss the authors' recommendations and clinical pearls, as well as evidence-based management for neuromodulators, soft tissue augmentation, chemexfoliating agents, and laser hair reduction in POC undergoing cosmetic procedures.

Telemedicine Alopecia Assessment: Highlighting Patients With Skin of Color.

Alopecia has been one of the more common concerns reported at teledermatology (TD) visits during the COVID-19 pandemic. In light of the growing use of TD, a team of experts were consulted to develop workflows for virtual hair and scalp examinations, with particular consideration for skin of color patients.
