Which company founder pitched the Tangle Teezer hairbrush on Dragon's Den?

Shaun Pulfrey founded Tangle Teezer and pitched the hairbrush on Dragon's Den.

Pulfrey appeared on the programme seeking investment for his detangling hairbrush design. The pitch is notable because the Dragons did not invest, yet Tangle Teezer later became a major international beauty brand. Its flexible teeth were designed to separate knots while reducing pulling and breakage.

The episode is frequently cited as an example of a business that succeeded without receiving a deal on the programme. A television rejection does not necessarily mean that a product lacks commercial potential; in this case, the company continued developing, manufacturing and selling the brush independently.

Shaun Pulfrey is the founder's name, while Tangle Teezer is the company and product brand. Those are related but different answers, which makes the founder the canonical response here.
