The "cure Brotzu" for baldness starts from Cagliari: "Thousands of signatures to market it" baldness CAGLIARI. It is called "Brotzu Lotion" and is a cure against alopecia discovered by Giovanni Brotzu, professor of vascular surgery at the University of Cagliari. Years of studies and research with appearances in important magazines, until the purchase in 2015 by Fidia Farmaceutici, which holds the patent. Yet the lotion has not yet entered the market and thousands of patients are waiting for the treatment. Delays and silence of the Venetian company led to the launch of a petition on the Change.org portal to request the commercialization of the cure for baldness, a pathology that affects more than 11 million people in Italy. A discovery that dates back to 2010 and was made by a native of Cagliari, son of art (the father Giuseppe, discoverer of a new class of antibiotics, the cephalosporins, which is called the hospital of the Sardinian capital, one of the most important Island).
