The researchers from the University of Manchester, UK, have found the drug that had a great effect on hair follicles in the laboratory, stimulating them to grow. The drug contains a compound targeting a protein that acts as a brake on hair growth and plays a role in baldness.
For the study, held in the laboratory, samples containing scalp hair follicles from more than 40 male hair-transplant patients were taken. The scientists used an old immunosuppressive drug, cyclosporine A, used for prevention transplant organ rejection and reduce symptoms of autoimmune disease.
The researchers concluded that this drug reduced the activity of a specific protein responsible for growth regulation in many tissues including hair follicles.
