Shaun Pulfrey founded Tangle Teezer after appearing as a contestant on BBC's Dragon's Den.
Pulfrey developed the Tangle Teezer, a hairbrush designed to detangle hair with reduced pulling and snagging. He presented an early version of the product on Dragon's Den, but the appearance did not result in an investment from the Dragons.
The business later grew outside the programme. Tangle Teezer became an internationally sold personal-care brand, and its distinctive flexible teeth became the central feature of its product identity. The company’s later success is often cited as a reminder that a televised refusal does not determine whether a business will succeed.
A common mix-up is to credit a Dragon with inventing the brush because the product became associated with the programme. The inventor and founder was Pulfrey, while the Dragons were potential investors rather than creators of the product.
