This review discusses the potential of human induced pluripotent stem cells for regeneratinghair follicles and developing cell-based therapies for hairloss, but it reports no new clinical results.
In this study, severe hairloss occurred in PKC epsilon transgenic mice treated with DFMO during skin tumor prevention, highlighting a link between polyamine biosynthesis, hair follicle maintenance, and metastasis suppression.

This review discusses the potential of adipose-derived stem cells for hairregeneration and suggests that these cells and their conditioned media may offer a promising strategy for treating hairloss.
Intermittent fasting may suppress hair follicle regeneration, but opinions vary on its impact on hairloss. Some users report no negative effects or even hair improvement while using treatments like finasteride and minoxidil.
Norwood 7 hairloss is often excluded from trials to ensure treatments appear more effective and to reduce costs. Some believe treatments effective for Norwood 5 could work on Norwood 7, but companies prioritize market readiness.
Pelage Pharmaceuticals announced positive Phase 2a trial results for PP405 in hairloss therapy. The conversation discusses the delay in publishing full results and the need for further trials and approvals.
Hairloss treatments like finasteride, minoxidil, and hair transplants have side effects and limitations. There is hope for future advancements in stem cell therapy and hair follicle regeneration, though skepticism about their effectiveness and timeline persists.
Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hair follicle regeneration and repair. Exosomes, which are not stem cells but products of them, contain bioactive chemicals and specific growth factors that promote new blood vessel formation, increase cell proliferation, reduce inflammation, and improve tissue repair, all crucial for hair health.
Can a hair transplant be combined with other treatments?Clinics commonly say a transplant is combined with other treatments, most often minoxidil, finasteride or PRP, but the evidence behind each add-on differs. Some of the add-ons offered, such as stem-cell or exosome products, are not approved treatments for hair loss.
When should I consider a hair transplant?Clinics generally consider a transplant when hair loss is stable and there is enough donor hair. Ask about the risks and about treatment for hair loss that continues.
What is follistatin, and how does it influence hair follicle growth and regeneration?Follistatin blocks activin and related growth-inhibiting proteins, which mouse studies link to hair follicle development and cycling; the only verifiable human evidence is a single small 2011 phase 1 injection trial, so follistatin remains experimental and is not an approved hair-loss treatment.
