Xtrallux is a family-owned medical device company founded in Miami by Carlos Piña, his wife Maria, and daughter Frances — the same family team that introduced the very first FDA-cleared home-use laser therapy cap for hair loss more than a decade before launching Xtrallux in 2021. Built on the philosophy that real, clinically-validated red-laser therapy belongs in your home rather than behind a clinic door, Xtrallux has created what hair restoration surgeons and dermatologists across the United States now describe as the most powerful and most laser-dense at-home hair regrowth device available anywhere in the world. Every Xtrallux device is FDA-cleared under 510(k) clearance K222364 as a Class II medical device for the treatment of androgenetic alopecia, uses true 650nm coherent red laser light with zero LEDs or mixed wavelengths, and is rated Class 3R safe per IEC 60825-1 international standards — meaning genuinely cold laser with no heat, no pain, and no side effects from daily use. The science is established and well-understood: Photobiomodulation Therapy at 650nm penetrates the scalp to reach hair follicle cells where cytochrome c oxidase in the mitochondria absorbs photonic energy and triggers increased ATP production, stimulating dormant follicles back into the active growth phase and producing thicker, more visible hair over months of consistent 6-minute daily sessions. The Xtrallux lineup spans three tiers of laser density: the Alpha with 136 VCSEL lasers providing essential scalp coverage, currently on sale at $699 (was $1,099, saving $400 in the America's 250th Anniversary Sale); the SuperPlus with 276 lasers for enhanced density treatment, now $1,099 (was $1,999, saving $900); and the flagship Turbo Pro with 316 VCSEL lasers — the most powerful at-home hair regrowth laser device on the market, delivering professional-grade scalp coverage for just $1,599 (was $2,999, saving $1,400). All devices ship free, include a travel case, universal AC adapter, and 4 international plug blades, and are backed by a 6-month money-back guarantee when the device is registered within 30 days of receipt.
