Which product inventor pitched the Tangle Teezer on Dragon's Den?

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

Pulfrey is a British hairdresser and inventor who developed a handheld detangling hairbrush designed to reduce pulling and discomfort when brushing wet or tangled hair. He presented the idea on the programme during its early years, but the Dragons did not invest in the business.

The rejection became part of the product's well-known commercial story. Pulfrey continued developing and selling the brush, and Tangle Teezer later became an international beauty brand. Its success is often cited as an example of a Dragon's Den pitch that did not receive investment yet ultimately built a substantial business.

The product is sometimes confused with conventional paddle brushes or with later celebrity-backed hair tools. Its distinctive feature is the arrangement of flexible teeth intended to move through tangles rather than forcefully pulling them. The inventor's name, rather than a Dragon's name, is the key identifying fact in this story.
