In their press release last year they mentioned
“In the sub-group of subjects (5 in total) whose scalp was pre-stimulated at the time of injection all subjects showed substantial and visible increased hair counts at 6 and/or 12 weeks (13-105%). We believe this increased hair production is attributable to the interaction between the injected DP cells and the stimulated resident hair producing cells.”
so I sent an email and here is the response. Not much info but gives an idea of baseline.
“All subjects in the study undergo serial hair counts in a defined region of the scalp. The percentage increases in hair count refer to the increase seen over the baseline hair count, as measured prior to treatment. Within the subset of five subjects who underwent pre-stimulation of the scalp prior to treatment, and who showed an increase in hair count of 13-105% at either 6 and 12 weeks, their baseline hair counts ranged from 85-247 hairs. The hair counts for individual subjects cannot be disclosed at this stage.”
