Role of Dermaroller-Mediated Microneedling in Hair Follicle Stimulation and Hair Growth

This review analyzed three studies on the use of dermaroller monotherapy for hair loss, revealing inconsistent efficacy and significant variability in needle length, frequency, and technique. The potential risks associated with this treatment include follicular damage, inflammation, and infection due to repeated trauma. The review emphasizes the urgent need for standardized protocols to guide clinicians and patients in the safe and effective use of dermarollers for hair growth stimulation.
