TLDR Using growth factors with microneedling is effective for treating hair loss.

The document discussed the use of growth factors in microneedling for the treatment of androgenetic alopecia (AAG). AAG is a result of hair follicles being stimulated by male hormones (testosterone) that begin to be produced in adolescence. A change in the follicular cycle, with shortening of the anagen phase, is responsible for the process of hair miniaturization. Microneedling was presented as a safe, quick, and effective method for aesthetic treatments, either by permeation of actives or by stimulating collagen and neovascularization. Microneedling can be associated with growth factors, which have a significant angiogenesis action, increasing the local microcirculatory process, activating cell division, and growth of new cells.
