1. Current Scientific Consensus

A randomized evaluator-blinded study of 100 men by Dhurat et al. (2013) demonstrated that weekly microneedling combined with topical therapy resulted in a significantly greater increase in hair count (+91.4 hairs/cm² vs +22.2 hairs/cm²) and superior patient satisfaction.

2. Major Unanswered Scientific Uncertainty

Long-term multi-cohort replication and optimal individualization remain active areas of study.
