What elevated Denman was an endorsement from hairdressing legend, Vidal Sassoon, who popularised Denman brushes through his revolutionary new blow-styling techniques in the 60s. The Denman brush was a perfect tool for creating smooth bobs and demand was such that production doubled in six consecutive years, requiring a second Denman factory to be built in Northern Ireland. Now, over 70 years since Jack Dean patented his first brush, Denman continues his company values of engineering excellence and innovation. The fact that Denman brushes are the first choice of professionals means they truly are the hairdressers’ hairbrush.
