Brief Summary

It has been postulated that Alopecia Areata (AA) is, at least in part, a neurologically mediated disease. Research supporting this theory includes the finding that nerves surrounding the hair follicles are collapsed. We want to take this research a step further and show that not only are these perifollicular nerves collapsed, but that their function is also impaired.
