I think this study should have been posted here before… I am not sure anyway here it is again just in case:
basically it is a study with 100 trialists (half with minox only and half with minox + dermarolling).
The dermaroller trail group was treated with a dermaroller once a week, after which 24 hours were waited until reapplying a two times daily dose of minoxidil.
A very significant increase in hair growth (with pictures) was observed in the dermaroll group at 12 weeks. Roughly 4x as effective as rogaine alone. I do not know if the results would have continued beyond the 4 month mark. It is possible however. Also the study concluded that the results were sustainable even after 8 months.
40 of 50 trailists went up 2 to 3 points on the NW scale.
It appears the skin wounding pushes follicles excretes alot of growth factors and pushes follicles into growth mode which is further supported by minoxidils rather unknown mechanisms of hair growth promotion.
I’m going to try to buy a 1.5mm dermaroller today and start testing this asap. Anyone interested in joining?
