Microneedling for Hair Growth: A Comprehensive Review of Its Efficacy in Androgenetic Alopecia
Dr. Kumar’s Take:
A recent systematic review and meta-analysis highlights the potential of microneedling (MN) as an effective adjunctive treatment for androgenetic alopecia (AGA). The findings suggest that combining MN with conventional treatments like minoxidil, finasteride, or platelet-rich plasma (PRP) leads to superior hair density and diameter improvements compared to monotherapy alone. Moreover, the therapy appears to be well-tolerated with minimal adverse effects.
Brief Summary:
This study reviewed 13 randomized controlled trials (RCTs) involving 696 AGA patients to compare the effectiveness and safety of MN therapy combined with other treatments versus monotherapy. Results showed that combined MN therapy led to statistically significant improvements in hair density, hair diameter, and physician-reported efficacy compared to monotherapy. However, patient satisfaction ratings did not differ significantly between the groups. Safety outcomes revealed no significant difference in adverse effects between combined and single therapies.
