Tangle Teezer, created by Shaun Pulfrey after Dragon's Den, is a hairbrush.
The product was designed to detangle wet or dry hair with flexible teeth that move through knots. Pulfrey developed it from his experience as a hairdresser and presented the invention on the British television programme in 2007.
Although the televised pitch did not produce a deal, the product found customers through continued development and marketing. Tangle Teezer later expanded into multiple brush designs for different hair types and styling needs.
The product is sometimes misidentified as a styling appliance because it became a well-known beauty brand. It does not generate heat like a hairdryer or straightener, and it is not a cosmetic liquid like shampoo. Its basic category is a hairbrush, specifically a detangling brush.
