Shaun Pulfrey founded Tangle Teezer before pitching his detangling brush on the UK show Dragon's Den.
Pulfrey developed the product after working as a hairdresser and noticing the difficulty of removing knots without damaging hair. The brush used flexible teeth arranged to separate tangles, giving it a distinctive design compared with conventional hairbrushes.
He pitched the business on Dragon's Den in 2007. Although the televised pitch did not produce an investment deal, Tangle Teezer later became a successful international brand and expanded into several brush designs.
The company is often confused with WetBrush or Denman, established hairbrush brands that were not founded by Pulfrey. Tangle Teezer is the brand name, while the detangling brush is the product category.
