Shaun Pulfrey pitched the Tangle Teezer on BBC's Dragons' Den.
Pulfrey appeared on the programme in 2007 and presented his design for a detangling hairbrush. The product used flexible teeth intended to remove knots while reducing pulling and discomfort, distinguishing it from many conventional brushes.
Although Pulfrey did not secure investment on the show, Tangle Teezer later became a successful international brand. The company expanded its range with brushes for different hair types and styling needs.
A common mix-up is confusing Tangle Teezer with professional hair-tool brands such as GHD or Denman. Those companies have different origins and product lines; Tangle Teezer specifically grew from Pulfrey's Dragons' Den pitch.
