    TLDR Combining micro-needling, LED therapy, and growth factors with Finasteride® significantly improves hair growth.
    The study evaluated the effects of combining micro-needling (MND), low-level LED therapy (LLLT), and growth factors (GFs) on hair regrowth in 20 patients with androgenic alopecia (AGA) already taking Finasteride®. Over a 20-week period, the treatment led to a statistically significant improvement in hair density by 19 ± 2 hairs/cm². Both physician and patient assessments indicated high satisfaction, with 75% and 85% reporting good results, respectively. The combination therapy appears to enhance nutrient delivery, promote angiogenesis, and cell regeneration, effectively boosting hair growth in patients not fully responsive to Finasteride®. Further research and large-scale trials are needed to standardize protocols and confirm these findings.

      The post discusses frustration over the limited and not always effective treatments for hair loss, mainly Minoxidil and Finasteride. The conversation includes mentions of potential new treatments like GT20029, HMI-115, CosmeRNA, KX-826, and microneedling, but also highlights the challenges of funding and prioritizing research in this area.

      Finasteride may take over two years to show results and can cause side effects like sexual dysfunction and emotional changes. Alternatives such as dutasteride and minoxidil are discussed, with varying effectiveness and side effects.
