In Dragon's Den, inventor Shaun Pulfrey pitched Tangle Teezer without securing a deal.
Pulfrey developed the detangling hairbrush after working as a hair colourist and becoming interested in reducing hair breakage and discomfort during brushing. He initially called the product Hair-Bruce, but later renamed it Tangle Teezer. The brush uses flexible teeth arranged to move through tangled hair, and it became a notable example of a product that attracted substantial public attention despite leaving the programme without investment.
Pulfrey appeared on Dragon's Den in 2007. The Dragons declined to invest, but the product later achieved commercial success through retail sales and international distribution. This is why the pitch is often cited in discussions of businesses that did not receive a television deal but went on to thrive.
The product is sometimes confused with other detangling brushes such as WetBrush or Denman. Tangle Teezer is the specific brand created by Pulfrey and associated with this Dragon's Den pitch.
