Microneedling is a minimally invasive dermatological procedure in which fine needles are rolled over the skin to puncture the stratum corneum. This therapy is used to induce collagen formation, neovascularization and growth factor production of treated areas. It has been used in a wide range of dermatologic conditions, including androgenetic alopecia (AGA) and alopecia areata, among others.
The use of microneedling has been most extensively studied in AGA and has been found to have positive therapeutic results, particularly when combined with topical treatments. It is thought that microneedling facilitates penetration of such first-line medications, and this is one mechanism by which it promotes hair growth.
