Definitely. Although this makes me wonder if it masks the itching which some associate with sebum production/miniaturisation...
Depending on the level of wounding, you do get some itch during the wound recovery, then it becomes difficult to tell whether it is the wound healing process or some nasty miniaturisation doing its thing. Either way, I do think it improves the scalp health (provided you're able to keep scalp from infection).
Can we simply think of microneedling as a way of 'scratching the itch' as well as providing the wounding needed for potential growth?
