β-catenin signalling in dermal papilla cells leads to a hairy situation.

Dermal papilla (DP) are specialised mesenchymal cells that activate the formation of new hair follicles. In this issue of The FEBS Journal, Zhang and colleagues show that enhancing the β-catenin signalling pathway in DP cells allows faster and denser hair growth, providing a potential target for hair loss treatments and for improving hair regeneration techniques.
