Hi, I'm Sebastian, founder of Folliq, based in Zwolle, Netherlands. Folliq makes red light scalp care for women with thinning hair, mostly women 45 and over. Our Red Light Scalp Massager combines 660nm LEDs with gentle massage in a six-minute at-home session, and we publish the actual dose (about 12 J/cm2 per session). We're honest about the evidence: the studies we cite tested lasers, not our LEDs, and we don't claim to cure hair loss. Read our Hair Growth Journal or visit the store using the button above.
