Scalp Microneedling

Scalp microneedling is most often discussed for androgenetic alopecia—the gradual thinning at the crown, part line, or hairline seen in male- and female-pattern hair loss. It is typically offered as one part of a broader plan that includes medical therapy, rather than as a stand-alone fix. Depending on the device, needling may be done with a roller, a stamp, or a motorized pen; deeper needling in particular is a medical procedure and belongs in a licensed medical setting.

The approach targets follicles that are miniaturized but still alive, so its realistic goal is to support density and hair thickness in thinning areas. It cannot revive follicles in areas that have been smooth and bald for years, and it does not relocate hair the way a hair transplant does—transplantation is a separate surgical procedure with its own entry. It also differs from scalp injection treatments such as mesotherapy, which deliver solutions into the skin; with microneedling, the needling stimulus itself is central.
