Among the many different laser cap/comb (low-level laser) treatments and combinations for hair loss, which works best, and is it as good as minoxidil?

Laser devices for hair loss (such as laser combs or caps) appear to help beyond placebo, and combining them with other treatments like PRP or minoxidil may boost results further -- though the specific 'best' combinations identified here are complex, specialist treatments rather than simple over-the-counter options.

What they did

Searched 7 databases through September 2024 and statistically ranked different low-level laser therapy (LLLT) treatments and combinations (laser alone, laser plus LED, laser plus PRP, laser plus botulinum toxin plus minoxidil, radiofrequency, etc.) against sham treatment and against each other.

What they found

For increasing hair thickness, red laser combined with LED and PRP injection ranked best (odds ratio 8.30 versus sham). For hair density, botulinum toxin plus red laser plus topical minoxidil ranked best (odds ratio 13.55). Nearly all laser-based treatments beat sham, except radiofrequency. No severe side effects were reported, though adverse events trended higher (not statistically significant) with laser-plus-PRP combinations.

Limitations

Full text could not be accessed (paywalled, payment required); findings rely on search-engine and secondary medical-news summaries. Network meta-analyses combine many small, heterogeneous trials through indirect statistical comparison, which is less reliable than a single large head-to-head trial; no India-specific or long-term (beyond study duration) data included.
