In Dragons' Den, what product did Tangle Teezer founder Shaun Pulfrey pitch?

In Dragons' Den, Tangle Teezer founder Shaun Pulfrey pitched a detangling hairbrush.

Pulfrey developed the Tangle Teezer after working as a hair colourist and observing how conventional brushes could pull and damage hair. The product used flexible teeth arranged to move through knots more gently than many standard brushes.

He appeared on Dragons' Den in 2007 but did not secure an investment. Despite that rejection, Tangle Teezer later became an international success and was sold through salons, retailers and online shops.

The product is often mistakenly described as a hair straightener because of its distinctive plastic shape. Its primary purpose is detangling, not heat styling or changing the hair's texture.
