Androgenetic alopecia and microneedling: Every needling is not microneedling
August 2019
in “Journal of The American Academy of Dermatology”
TLDR Microneedling improves hair growth in androgenetic alopecia when combined with minoxidil.
The authors of this letter to the editor disagree with a previous study's contention that microneedling is ineffective as a treatment for androgenetic alopecia (AGA). They clarify that microneedling should not be confused with needling, and that microneedling has been shown to improve hair growth in patients with AGA when used as an adjuvant to minoxidil. They also note that the number of dermal pricks inflicted by microneedling is much greater than the number of subcutaneous injections used in the previous study. The authors suggest that the previous study's argument on microneedling being ineffective in the treatment of AGA is premature and lacks evidence.
