Suffused with the sting of hair spray and the scent of Herbal Essences, “Medusa Deluxe” swaggers onto our screens, all cigarette smoke and mirrors. From its playfully inventive opening to its flash-forward finale, Thomas Hardiman’s wild — and wildly impressive — first feature, set during a British regional hairdressing competition, is a proudly indelicate, painstakingly structured pleasure. Playing out in real time and shot to suggest a single, continuous take, the plot circles the sudden death of the show’s star stylist, who has been found backstage, minus his scalp. As his competitive rivals and their models await questioning by unseen detectives, everyone is under suspicion, not just the creepy security guard with the urgent requests for wet wipes. There’s the mouthy Cleve (Clare Perkins, whose opening monologue is a doozy), a stylist with barely controlled anger issues; the devout Divine (Kayla Meikle), who works part-time for an undertaker and is hence no stranger to dead heads; and the scheming Kendra (Harriet Webb), who may have fixed the contest in cahoots with its silver-pompadoured organizer (Darrell D’Silva).
