Minoxidil has become an increasingly popular treatment option for hair loss disorders including androgenetic alopecia, cicatricial alopecia, and alopecia areata. There are various minoxidil formulations available including topical, oral, and injectable minoxidil. While injectable minoxidil may offer certain advantages, potential risks and costs should also be considered. First, we explore the enhanced bioavailability of injectable minoxidil in comparison to topical and oral formulations, as well as the variability in sulfotransferase enzyme levels and its role in the activation of minoxidil at hair follicles. Furthermore, we expand upon the potential adverse effects associated with injectable minoxidil given its widespread systemic distribution. We also highlight the importance of considering cost, access, and availability of injectable minoxidil given that injections are significantly more expensive than oral minoxidil tablets and involve the additional obstacle of frequent dermatology visits. Depending on geographic region and socioeconomic status, many patients may not live in sufficiently close proximity to a dermatologist for this level of care. Finally, we emphasize the need for ongoing research efforts to compare the efficacy, access, and tolerability of injectable minoxidil, alternative minoxidil formulations, and other alopecia medications.

Premature hair graying (PHG) is the early loss of natural hair color, influenced by genetic, biological, and environmental factors. This review discusses the significant psychological impacts of PHG and explores its underlying mechanisms, related health conditions, and available treatments. The review examines the roles of genetics, oxidative stress, and lifestyle factors such as smoking and diet in premature graying. It also considers associated medical conditions and current and emerging treatment options. This overview aims to improve understanding of PHG and its broader implications.
