The hairbrush company founded by Dragons' Den contestant Shaun Pulfrey was Tangle Teezer.
Shaun Pulfrey developed the original Tangle Teezer after working as a hairstylist and looking for a better way to remove knots. The brush's flexible teeth were intended to glide through tangled hair without the same level of pulling as many traditional brushes.
Pulfrey pitched the invention on Dragons' Den and secured backing from Theo Paphitis. The company then moved beyond the original product, introducing different shapes and designs for wet hair, thick hair, children, and styling. Its name became closely associated with detangling brushes in the British market and internationally.
Tangle Teezer is the company and brand name, not merely the generic description of the product. Another common confusion is to credit the invention to a Dragon: Paphitis invested in the business, but Pulfrey created it.
