“It is really no overstatement to say that Zoltan has revolutionised my look. Blowdrying is now something I can do myself rather than having to book in to a salon twice a week. And even if I don’t have time for that and have to leave it to dry naturally, my hair is now richly curly rather than impossibly frizzy.” — Sasha Slater, Deputy Editor, Town & Country and Harper’s Bazaar
