Julian Perlingiero is a precision haircutting educator who helps stylists turn “I think this will work” into “I know this will land.” Based in Brooklyn, New York, he’s known for teaching geometric fundamentals in a way that feels practical behind the chair—clean sections, clear guides, and the kind of refinement that makes a bob look expensive from every angle.

His story runs through the serious rooms: after apprenticing at Vidal Sassoon, he moved from successful stylist to full-time educator at the Sassoon Academy, rising into Creative Director while helping reinvent the geometric cutting system many hairdressers still rely on. That background shows up in everything he teaches—control and discipline, balanced with suitability (because a perfect shape still has to fit the person wearing it).

Julian’s education lives in multiple formats: online courses through Hairbrained Live Academy (including Precision Cutting: Bobs and The Comprehensive Cutting Program) and hands-on sessions with brands and academies. If you want tighter technique, cleaner results, and a cutting framework you can build a whole career on, his work is an easy “start here.”
