A
2002 study from the Orentreich Foundation for the Advancement of Science transplanted both balding and non-balding human hairs into the backs of mice. 22 weeks later, what were the findings?
The balding human hairs had regenerated just as well as the healthy non-balding hairs… and this regeneration happened in a
single hair cycle.
In fact, those balding hairs
continuedthickening through the duration of the study… whereas the non-balding hairs, for reasons unknown, plateaued after 17 weeks.
Even odder – the balding hairs regenerated in a single hair cycle – much
faster than hair recoveries seen from finasteride in humans. To the researchers, this suggested the influence of non-androgenic factors in the recovery of those hairs. Yet that was as far as they could extrapolate.
