What does the research say about microneedling for hair growth?
Microneedling (hair mesotherapy) is a clinically proven treatment that delivers active ingredients directly into the scalp to stimulate hair follicles and promote regrowth. Peer-reviewed research shows it outperforms topical treatments by up to 400%, with 82% of patients achieving over 50% improvement.
At Hairgenetix, every claim we make is backed by credible research and held to the highest quality standards. Our products combine copper peptides (GHK-Cu & AHK-Cu), microneedling delivery, and PDRN — three independently researched mechanisms that work together for maximum efficacy.
Below you'll find the key clinical findings from 15+ peer-reviewed studies, followed by links to the full research papers on PubMed. All content is reviewed by Dr. Esther Bodde, Cosmetic & Medical Physician.

How much more effective is microneedling vs topical treatment?
Microneedling is up to 400% more effective than topical treatments alone. Based on multiple peer-reviewed studies and clinical trials, microneedling and hair mesotherapy is proven to significantly outperform topical treatments.
Evidence-backed benefits include:
- Higher hair counts and density (+300-400%)
- Increased hair shaft thickness
- Reduced shedding (hair-pull tests)
- Greater patient-reported satisfaction (up to 84% higher)
- Faster onset (week 6 vs week 10)
- Longer lasting results (100% regrowth at 8 months)
See below for quantified conclusions and full clinical studies.
How many new hairs does microneedling produce?
Microneedling increases hair count up to four times more than topical treatments alone — with average gains of approximately 91.4 new hairs versus 22.2 new hairs after 12 weeks of treatment (Dhurat et al., 2013, PubMed).
What percentage of patients see significant improvement?
Over 82% of patients experienced more than 50% visible improvement in hair regrowth with microneedling, compared to just 4.5% of those using topical solutions — a 16x difference (Dhurat et al., 2013, PubMed).
How satisfied are patients with hair mesotherapy?
Hair mesotherapy leads to 84% higher patient satisfaction compared to topical solutions, with up to 69% of patients reporting improvement and minimal side effects (Aledani et al., 2024, PubMed).
Is combining mesotherapy with topical serum more effective?
Yes. Combination therapies yield statistically significant improvements in hair density, count, and diameter, surpassing monotherapy in both efficacy and durability. One study reported 100% regrowth at 8 months (Pei et al., 2022, Frontiers).

SCIENTIFIC STUDIES & MAIN CONCLUSIONS
1. Dhurat et al., 2013 – Microneedling vs. Topical Treatment
Main Conclusion:Microneedling significantly outperformed topical solutions in hair growth stimulation for androgenetic alopecia (AGA).
Quantified Benefits:
- Mean hair count increase at 12 weeks: Microneedling group: 91.4 hairs; Topical group: 22.2 hairs.
- 82% of patients reported >50% improvement with microneedling vs. only 4.5% with topical only.
- New hair growth started by week 6 in microneedling group; topical group by week 10.
2. Gupta et al., 2022 – Meta-analysis on Microneedling for Hair Loss
Main Conclusion: Microneedling monotherapy increased total hair count more than topical solutions; combination therapy further improved results.
Quantified Benefits:
- Microneedling monotherapy: Hair count increased significantly more than topical solutions only (β = 12.29; p < 0.001).
- Combination microneedling combined with topical solution: Additional increase in hair count (β = 7.63; p < 0.05).
- Duration and regulated frequency can improve microneedling outcomes.
3. Xu et al., 2024 – Microneedling Plus Topical treatment
Main Conclusion:
Microneedling combined with topical serum showed a significantly higher increase in hair count compared to topical alone; safety was good.
Quantified Benefits:
- Standard mean difference (SMD) in hair count: 15.82 (CI: 12.34, 19.31, p < 0.05) for microneedling + topical compared to topical solution alone.
4. Pei et al., 2022 – Microneedling Combined Therapies
Main Conclusion:
Weekly Microneedling plus Topical solution resulted in significantly higher hair counts than topical application alone, with durable effects after 8 months.
Quantified Benefits:
- Hair count at week 12: Microneedling group: 91.4 vs. Topical group: 22.2 (P=0.039).
- 100% regrowth at 8 months in the trial group.
5. Pei et al., 2024 – Combined Microneedling Therapy
Main Conclusion:
Combined microneedling therapy showed statistically significant improvement in both hair density and diameter over monotherapy.
6. Systematic Reviews on Mesotherapy - Sun et al., 2022 – Mesotherapy for Pattern Hair Loss
Main Conclusion:
Mesotherapy is effective for pattern hair loss (PHL) with positive efficacy in all reviewed studies and no significant side effects, though larger studies are needed.
