Professional Laser Hair Growth Comb for Androgenetic Alopecia Treatment - 650nm Wavelength Therapy Device

Basically you're getting 9 Gaaias semiconductor diodes firing at 650nm into the scalp, and the comb's teeth part the hair so the light actually reaches the follicle rather than just bouncing off — it's FDA cleared for androgenetic alopecia in both men and women, which is the main reason we ordered this over cheaper LED caps that don't have teh same regulatory backing.

650nm sits right in the sweet spot for stimulating follicular metabolism, and with 9 diodes you're looking at about 15-30 minutes per session depending on the pattern you're treating. It's non-invasive, no pain, no side effects, and Fitzpatrick skin types I through IV — so most of our lab's subjects will be covered, though we usually have stock but confirm lead time if you need more than 20 units or so.

What it does in practice is increase microcirculation and ATP in the dermal papilla cells, which pretty much kicks stalled follicles back into anagen phase. We've used it alongside minoxidil in a few studies and the combination works better than either alone, but it's not suited for scarring alopecia or patchy autoimmune hair loss — just androgenetic patterns, Norwood IIa to V for men and Ludwig I-4 or II-1/2 for women.

Each unit ships with a COA and the CE/ROHS/ISO13485 docs are included — the input votage is 100-240VAC at 50/60Hz so no step-down transformer needed. The 9 diodes (usually 5mW or 10mW depending on your batch) have a tighter tolerance than most consumer units I've seen, and the housing is comfortable for 30-minute holds, though it's a bit heavier than the cheaper plastic combs.
