A randomised trial in 40 women with pattern hair loss: adding weekly microneedling to 2% minoxidil nearly doubled the response rate. The full plain-language report.

A three-arm randomised trial in 60 men: microneedling alone beat minoxidil alone on hair density, and the combination beat both. A follow-up study tied the effect to the Wnt gro...

The newest meta-analysis pools 12 randomised trials and 631 patients: adding microneedling to minoxidil produces a large, significant hair count gain, and needle depth mattered ...

A 120-woman randomised trial compared minoxidil alone, minoxidil plus microneedling, and minoxidil plus oral spironolactone. The microneedling arm gained the most hair density w...

A blinded randomised trial in 68 men added weekly microneedling to 5% minoxidil. Hair count gains were several times larger with the combination. The full plain-language report.

A randomised trial gave 30 men four monthly scalp microneedling sessions with no topical treatment. Hair density did not improve. What that means, and what to combine needling w...

Three device types, one variable that actually has trial evidence behind it. Which at-home microneedling device suits you — and what none of them has been proven to do.

Microneedling does regrow hair — but the evidence is strongest alongside a topical, not on its own. Depth, frequency, what to pair it with, and a realistic 12-week timeline.

For scalp use a derma stamp beats a derma roller on depth control and safety — but the landmark clinical trial used a roller. We compare needle entry angle, depth and the actual...

Independent comparison of the top 5 at-home hair mesotherapy kits. EMS technology, needle depth, serum compatibility, and which delivers the most clinically validated results.

Key Takeaways Shallower needles (0.6mm) outperformed deeper needles (1.2mm) — this randomised controlled trial found that 0.6mm microneedling combined...

Key Takeaways Combining microneedling with minoxidil significantly increases hair count — this meta-analysis of 10 randomised controlled trials (466 p...

Key Takeaways Combined microneedling is better than any single treatment — pooled data from 13 randomised trials (696 patients) shows significantly gr...

Key Findings at a Glance Microneedling + minoxidil significantly outperforms minoxidil alone: Across 8 RCTs with 472 patients, the combination produced significantly mor...

Key Findings at a Glance Microneedling alone beats minoxidil 5%: Microneedling monotherapy produced significantly more hair growth than the gold-standard topical treatme...

Key Findings at a Glance 4× more hair growth: Microneedling + minoxidil produced +91.4 hairs/cm² versus +22.2 hairs/cm² with minoxidil alone — a fourfold improvement (p ...

Key Findings at a Glance A combination treatment of minoxidil, dutasteride, and copper peptides delivered via "tattooing" microneedling produced a median 26.5% hair regrow...
