In this study, nestin-expressing cells in the hairfollicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hairfollicle outer-root sheath.
In this study, hairfollicle-derived mesenchymal stromal cells showed potential for immunomodulation, with equivalent or superior responses compared to those from adipose tissue, suggesting a promising alternative cell source.
This study suggests that human DSCCs may aid in hairfollicle regeneration and reduce microinflammation, with potential applications in regenerative medicine evaluated through a new morphometric analysis.

This study reports the cloning and expression details of two new human type II keratins, K6irs3 and K6irs4, in the hairfollicle's inner root sheath, suggesting a distinct functional role related to hair structure.
A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.
Hair cell therapy and follicle cloning are still in experimental stages, with treatments like hair multiplication and regenerative hair therapy being marketed but not yet proven to create unlimited new follicles. There is skepticism about the effectiveness and legitimacy of these treatments, with some considering them scams.
David Barreto shared that a London-based research group is conducting a 12-month trial for a new nutraceutical treatment for pattern hair loss, designed with Dr. Carlos Puig. The trial aims to provide robust data, with results expected in 1-2 years, potentially representing a significant advancement since finasteride’s introduction in 1997.
Shiseido's S-DSC hair regenerative treatment in Japan focuses on improving existing hair by thickening miniaturized follicles, not creating new ones. There is limited patient feedback and long-term data available.
