By combining lineage tracing with intravital microscopy, the position of a stem cell within its extended mouse hair follicle niche is shown to control its long-term fate and behaviour; laser ablation to remove restricted cell populations shows that bulge stem cells are dispensable for hair regeneration, and non-hair epithelial cells may change their fate to compensate and sustain hair growth.
