Clinical Study - Microneedling - shocking how much more regrowth you can get - Numbers don't lie

Most people know that microneedling in conjunction with topical minoxidil has a higher efficacy in promoting hair regrowth than topical minoxidil alone.

But how much better?

Here we have a study published in the International Journal of Trichology.

The study involved a hundred cases of norwood 3 and norwood 4 test subjects broken into two groups.

Group 1 was given weekly microneedling treatment with twice daily 5% topical minoxidil.

Group 2 was given 5% topical minoxidil only.

After a period of 12 weeks, it was shown that hair regrowth in the microneedling group was statistically superior than the minoxidil group.

Specifically, the mean change in hair count at week 12 for the Microneedling group was 91 vs 22 for the Minoxidil group, more than 4 times more effective!!

I knew the improvement would be statistically significant, but I did not expect it to be more than FOUR FOLDS !! A very welcoming surprise.

ok i am sold. Are they all the same ? do they come in different types? is one brand more effective than the other?
