Makes sense as I assume muscles around hair shaft can get more erect due to secretion of PGD2Are you people really spatting over this? FFS.
Maybe the follicles are standing up a little straighter or more uniformly after a needling session. That would be a skin effect, not an effect on the hair shaft itself. But it could give the impression of healthier hair. This would explain it just fine.
The scalp skin would be reddened after a needling session. That might look darker, which would visually imply denser hair coverage. Maybe that's a contributing factor too.
