Shaun Pulfrey created the Tangle Teezer after appearing on the UK show Dragon's Den.
Pulfrey developed the detangling hairbrush after working as a hair colourist and noticing how conventional brushes could pull and damage hair. The Tangle Teezer uses flexible teeth arranged to pass through tangles with less pulling than many traditional brushes.
Pulfrey presented the idea on Dragon's Den but did not secure an investment. He continued developing the product independently, and the brush later became an international beauty product. Its story is often cited as an example of a rejected pitch that nevertheless found a substantial market.
The product name refers to its intended use rather than to a person. Tangle Teezer later expanded beyond the original design into several brush types for different hair needs.
