Alopecia areata is an autoimmune disease of the hair follicles that cause an unpredictable hair loss. The disease prevalence is estimated about 2% in general population though the lifetime. The disease is associated with various other concurrent disorders such as depression, thyroid diseases, and anxiety. Cannabis receptors especially (CB2Rs) are found on immune cells, including lymphocytes, macrophages, mast cells, natural killer cells, peripheral mononuclear cells, and microglia.
In this Case, a 15 year-old girl had Alopecia Universalis and multiple psychiatric diagnoses. She was self-medicated for her symptoms by using Cannabis and as coincident her hair stated to grow back. In this case, I would like to grab attention for cannabis as a possible cure with eliminating its side effect
