The results were stunning.....
The improvement in total hair density from baseline to 24 weeks resulted in the following:
Group 1 (topical 5% minoxidil): 18.8 cm2
Group 2 (microneedling only every 2 weeks): 23.4 cm2
Group 3 (microneedling + minoxidil 5%): 38.3 cm2
It clear to see that microneedling with topical minoxidil 5% resulted in the best hair growth, but this study also confirms that microneedling by itself is more effective in regrowing hair than a standalone treatment of topical minoxidil 5%.
So you want average regrowth not maximum one. Sure, why not.
