New Drugs for Alopecias

The new drugs in the development of AGA include PGF2 analogs, a PGD2 receptor antagonist, Wnt pathway activators, an androgen receptor antagonist, a topical JAK inhibitors, and topical finasteride. While many of these have already shown efficacy compared to placebo, none have shown superiority to topical minoxidil; however, they may still have future as an adjuvant treatment with topical minoxidil. For AA, oral JAK inhibitors are a promising new development, although other new drugs are in development as well. A particularly interesting one is BNZ-1, which has the potential to suppress the autoimmune response without causing systemic immunosuppression

Role of Oral Supplements: When and How to Choose

People commonly inquire about vitamin and mineral supplementation and diet as a means to prevent or manage dermatological diseases and, in particular, hair loss. Answering these queries is frequently challenging, given the enormous and conflicting evidence that exists on this subject. There are several reasons to suspect a role for micronutrients in non-scarring alopecia. Micronutrients are major elements in the normal hair follicle cycle, playing a role in cellular turnover. The role of nutrition and diet in treating hair loss represents a dynamic and growing area of inquiry. This chapter summarizes the role of vitamins and minerals in non-scarring alopecia. Micronutrients such as vitamins and minerals play an important, but not entirely clear role in normal hair follicle development and immune cell function. Deficiency of such micronutrients may represent a modifiable risk factor associated with development, prevention, and treatment of alopecia
