Should such genes be identified I am sure several research groups will attempt to develop gene therapy for alopecia areata. This is perhaps the most likely area for development of new treatments in the near future. Several pharmaceutical companies are hard at work developing drugs with immunosuppressive properties. One or more of these drugs could be effective in alopecia areata. What exactly the pharmaceutical companies are developing is unknown.
Industrial science is very secretive about new drugs.
As new drugs are brought to market they will probably be tested for their effectiveness as alopecia areata treatments.
