TB-500 Support Hair Regrowth Research: Rodent vs Human Comparison
Cycle Duration 21–28 days (full cycle) 2–7 years (anagen alone) Effects observable in weeks in rodents may require years in humans Synchronization Highly synchronized across dorsal skin Mosaic pattern. Each follicle on independent cycle Rodent studies measure
This comparison does not assign a generated winner or score.
- Cycle Duration
- 21–28 days (full cycle)
- 2–7 years (anagen alone)
- Effects observable in weeks in rodents may require years in humans
- Synchronization
- Highly synchronized across dorsal skin
- Mosaic pattern. Each follicle on independent cycle
- Rodent studies measure cohort transitions; human trials must measure per-follicle density changes
- Dermal Papilla Depth
- 200–400 µm below epidermis
- 3,000–5,000 µm below epidermis
- Topical penetration far more challenging in humans
- Androgen Sensitivity
- Minimal DHT influence on cycle regulation
- DHT drives miniaturization in genetically susceptible follicles
- TB-500 may improve vascularization without reversing androgen-driven miniaturization
- Vascular Density Baseline
- High capillary density in anagen follicles
- Reduced microvascular density in androgenetic alopecia
- TB-500 support hair regrowth research effects may be larger in androgen-affected human scalp
- Bottom Line
- TB-500 shortens telogen and increases anagen entry rate in rodent models with statistical significance (p < 0.05 in published studies). Whether this translates to increased terminal hair density in human androgenetic alopecia or telogen effluvium remains entirely speculative without Phase 2 trial data.
