About this video

Gillett and James O’Hara review an investigational hair-loss candidate described as targeting scalp stem cells, contrasting it with existing approaches that, they explain, either reduce DHT or stimulate growth. They stress that the available results come from an early-phase trial and amount, in their view, to a teaser rather than proof. Gillett argues headline density gains are hard to interpret without baseline hair counts, warns that follicles with no remaining stem cells cannot be reactivated by this mechanism, and questions whether any early gain will be durable. Their conclusion is cautious interest, not readiness for clinical use, pending larger and longer trials.

Key takeaways

  • Judge early-phase hair-loss results as preliminary, not as proof of efficacy
  • Percent density gains mean little without knowing the starting baseline
  • Gillett theorizes stem-cell approaches need a stem cell still present to work
  • Short trials can reflect hair-cycle shifts rather than lasting regrowth
  • Wait for later-phase data before comparing a candidate to established treatments
