Shaun Pulfrey pitched the Tangle Teezer hairbrush on the British show Dragon's Den.
Pulfrey was a professional hairdresser who developed the Tangle Teezer after working on a design intended to remove knots without pulling hair in the same way as conventional brushes. He presented the product on Dragon's Den, but the appearance did not produce an investment deal.
The brush later became a major commercial success and was sold internationally. Its flexible teeth and distinctive shape became central to the product’s identity, helping it stand apart from ordinary flat brushes and combs.
The story is often remembered because it illustrates that a Dragon's Den rejection is not a final verdict on a business. Television investors assess a pitch at a particular moment, while later manufacturing, branding, distribution and customer response can change a product’s prospects dramatically.
