What type of product did Shaun Pulfrey pitch when he appeared on the BBC programme Dragon's Den?

Shaun Pulfrey pitched a detangling hairbrush when he appeared on the BBC programme Dragon's Den.

Pulfrey invented the Tangle Teezer, a brush designed to remove knots from hair while reducing pulling and breakage. His appearance brought attention to a product based on a simple but specific consumer problem: detangling hair more comfortably.

The Tangle Teezer uses rows of flexible teeth with different lengths and spacing. That design distinguishes it from ordinary rigid brushes and combs, although the product is still commonly described in everyday language as a hairbrush.

A frequent mix-up is to call Pulfrey's invention a styling tool such as a curler or straightener. Its defining purpose is detangling, not heating or reshaping hair. The company later developed several versions for different hair types and grooming needs.
