Potrebbe essere la volta buona: arriva la pillola anticalvizie, la cui commercializzazione è stata autorizzata negli Stati Uniti. Il farmaco, garantiscono i produttori, è in grado di far ricrescere una folta chioma a chi è affetto da alopecia areata, patologia caratterizzata dalla perdita parziale, spesso a chiazze, o totale dei capelli.
Come riferisce la rivista Nature Medecine, lo studio pilota condotto presso il Columbia university medical center ha dimostrato l'efficacia della cura: nel giro di 4-5 mesi, i pazienti sottoposti a terapia hanno visto la loro capigliatura riformarsi completamente.
L'alopecia areata, che colpisce sia uomini che donne, è malattia di origine immunitaria relativamente diffusa ed è causata da cellule "impazzite" che attaccano il follicolo costringendolo a uno stato di dormienza. Non va confusa con la più comune "pelata".
