Which product did Shaun Pulfrey pitch on the UK television series Dragon's Den?

Shaun Pulfrey pitched the Tangle Teezer on the UK television series Dragon's Den.

Pulfrey presented his detangling hairbrush invention on the programme in 2007. The product used flexible teeth designed to remove knots while reducing pulling and discomfort. The Dragons did not invest in the business during the pitch.

Despite the lack of a deal, Tangle Teezer later became a successful international brand. Pulfrey continued developing and marketing the product, and the company expanded its range to include brushes for different hair types and styling needs.

The story is frequently cited as an example of a business gaining publicity even when the entrepreneur leaves without investment. It also illustrates that a televised rejection is not the same as a verdict on a product's long-term commercial potential. Tangle Teezer is a brand name, not the name of Pulfrey's company or the television programme.
