Shaun Pulfrey pitched his detangling hairbrush company, Tangle Teezer, on Dragon's Den.
Pulfrey developed the product after working as a hair colourist and noticing that conventional brushing could pull and damage tangled hair. The Tangle Teezer uses flexible, differently sized teeth designed to separate tangles with less tugging than a traditional brush. Its distinctive shape and bright colours helped it stand out in the hair-care market.
Pulfrey appeared on the programme in 2007 and accepted an investment offer from Theo Paphitis. The company later expanded internationally and sold the brush through salons, retailers and online channels. The pitch is often cited as an example of a specialist product finding a much larger consumer audience.
Tangle Teezer is the company and brand name, while Shaun Pulfrey is the inventor and entrepreneur behind it. It is therefore more precise than answering with “hairbrush,” which describes the product category rather than the named business.
