Tangle Teezer is the company that makes the Tangle Teezer hairbrush promoted on the British show Dragon's Den.
The product was created by British hairdresser Shaun Pulfrey, who developed a flexible-bristled brush designed to remove tangles while reducing pulling. Pulfrey presented the idea on Dragon's Den, and the product later became an international success in the hair-care market.
The name can refer both to the original brush and to the company that developed the brand. That overlap is why questions about the pitch can seem to invite either “Shaun Pulfrey” or “Tangle Teezer”. The entrepreneur is Pulfrey; the product and company name are Tangle Teezer.
Tangle Teezer is also easy to confuse with other detangling brands such as Wet Brush or Denman. Those are separate companies and products. The Dragon's Den connection specifically concerns Pulfrey's flexible, distinctive brush and the brand that grew from it.
