Microneedling can improve scar tissue outcomes on the scalp and skin by eliciting an inflammatory response that reduces scar tissue and improves hair counts.

“the way that micro needling works is for anybody who doesn't know what these devices are they basically look like tiny medieval torture devices they're little rollers with a bunch of spikes on them that are medical grade needles and you roll them on your skin to elicit an inflammatory response that's acute but in that elicitation of inflammation you send signaling proteins that not only help to reduce scar tissue long term or at least attenuate and partially reverse that scar tissue but you also initiate antigen signaling that improve hair counts over time and we've seen this over and over in the research”
