I believe it's because very few people have actually replicated the results of those studies. Sure, there are a lot of regrowth cases here,
but most of those are also minoxidil starters so they are not isolating needling'a effect. Those who tried needling that were already on minoxidil for years hasn't fared so well, so given that, we are trying to tweak on the details to see what works best. The daily needling thing is based on a few anecdotes of a couple of dudes (one of them is
@chen ). Sadly, there are still no controlled studies testing daily needling, and we still don't have enough people doing it daily to conclude anything robust.
There's nothing to lose trying the daily regime, as at least there are no reports on daily needles who have increased hairloss on such method.
