Hair Regrowth Research

Androgenetic alopecia (AGA) is the most common form of hair loss in adults, which is generally progressive in the absence of treatment. As a head full of healthy hair adds to the cosmetic appeal of the individual, the consequences of AGA are predominantly psychological. Currently, topical minoxidil is the first-line treatment for AGA. Many adjuvant treatment modalities have been used synergistically with minoxidil. Microneedling is one among such adjuvant treatments, which works by various mechanisms to stimulate the dermal papillary cells that play a key role in hair growth.

Alopecia areata is an autoimmune disorder characterized by transient, non-scarring hair loss and preservation of the hair follicle. Hair loss can take many forms ranging from loss in well-defined patches to diffuse or total hair loss, which can affect all hair bearing sites. Patchy alopecia affecting the scalp is the most common type. Alopecia areata affects nearly 2% of the general population at some point during their lifetime. Skin biopsies of alopecia areata affected skin show a lymphocytic infiltrate in and around the bulb or the lower part of the hair follicle in anagen (hair growth) phase. A breakdown of immune privilege of the hair follicle is thought to be an important driver of alopecia areata. Genetic studies in patients and mouse models showed that alopecia areata is a complex, polygenic disease. Several genetic susceptibility loci were identified associated with
