On Dragon's Den, which entrepreneur founded the hair-styling company Tangle Teezer?

Shaun Pulfrey founded the hair-styling company Tangle Teezer.

Pulfrey, a British hairdresser and inventor, developed the detangling brush after working on a design intended to remove knots without pulling hair as harshly as ordinary brushes. He appeared on Dragon's Den to seek investment for the product, but the pitch did not produce a deal with the dragons.

Despite that setback, Tangle Teezer grew into an international brand. The company later sold brushes in many markets and expanded its product range, demonstrating that a televised rejection does not necessarily predict a product's commercial future.

Tangle Teezer is sometimes confused with products that received investment on the programme. Its connection to Dragon's Den is especially notable because Pulfrey's business succeeded after leaving the den without the funding he had requested.
