Vitamin D deficiency may occur at a higher rate in these patients. Alopecia areata has had new developments in treatments. Clinical reports have shown that Allegra antihistamine as well as Zocor, the cholesterol drug, may be helpful. Topical steroids and intralesional injections have been the mainstay of treatment .
