The hairbrush business rejected on Dragon's Den later became famous as Tangle Teezer.
Inventor Shaun Pulfrey presented the product on the British programme, seeking investment to develop and market his detangling brush. The Dragons did not make an offer, but the televised rejection did not prevent the product from becoming commercially successful. Tangle Teezer subsequently developed into an international hair-care brand.
The brush uses flexible teeth designed to move through tangled hair with less pulling than many conventional brushes. That product description helps distinguish Tangle Teezer from ordinary salon brushes and from unrelated hair-tool brands such as Denman and GHD.
The story is often cited as an example of television exposure not necessarily depending on a successful deal. A pitch can be rejected by the panel while still attracting public attention, customers and later business opportunities. Tangle Teezer's post-show growth made the rejected pitch one of the programme's most frequently remembered outcomes.
