Photobiomodulation Therapy in a wearable cap. Clinically proven to treat androgenetic alopecia in men and women. 6 minutes per day.
From the family that introduced the very first FDA-cleared home-use laser therapy cap for hair loss.
Photobiomodulation Therapy (PBM), also called Low-Level Laser Therapy (LLLT), is a clinically validated form of light medicine. The light is non-thermal: it doesn't heat or burn. It stimulates.
A clinically-proven form of low-level laser therapy. The light is non-thermal: it doesn't heat or burn. It stimulates the cells beneath the skin.
At a wavelength of 650 nanometers, red light penetrates the scalp and is absorbed by the mitochondria of the hair follicle cells, increasing cellular energy (ATP) at the root.
Restores weak follicles, extends the anagen (growth) phase, and produces thicker terminal hairs in place of miniaturized vellus hairs caused by androgenetic alopecia.
For Hair Growth: ~630–660 nm (Red Light)
For Other Purposes: ~808 nm (Infrared, non-visible)
Yes. FDA-cleared for hair regrowth using red light (~650 nm). 510(k) K222364.
Core wavelength range: ~630–660 nm (most commonly ~650–655 nm). This is the core wavelength range used in predicate devices and the clinical foundation behind FDA clearances for treating androgenetic alopecia.
TipLook for the number of true red lasers (~650 nm) used for hair growth.
Xtrallux laser devices are FDA-cleared as safe and effective for the treatment of androgenetic alopecia, using red light in the 640–660 nm range: the clinically established standard in FDA-cleared laser hair growth therapy. That's why every diode in our caps operates within this proven range for consistent, targeted energy delivery.
The wavelength behind the clinical foundation of androgenetic alopecia treatment. FDA-cleared at-home laser devices in this category are based on predicate technologies using red light in the 640–660 nm range: delivering targeted energy to the follicle without heating the scalp.
A search of the FDA 510(k) database for hair-regrowth devices (Class OAP) does not show 808 nm lasers as part of the clearance pathway. 808 nm is near-infrared light: a different region of the spectrum used in other medical applications, separate from the visible-red technology used in FDA-cleared hair-growth devices.
Built for one purpose: hair regrowth. Every Xtrallux device is FDA-cleared for it, and every diode delivers true 650 nm red.
A growing body of randomized controlled trials and systematic reviews support 650 nm low-level laser therapy for androgenetic alopecia.
RCT n=42 women, 16 weeks, 655 nm device → 37% increase in hair count vs sham (48% active vs 11% control). No side effects.
Read on PubMed →RCT n=41 men, 16 weeks, 655 nm helmet → 39% increase in hair counts in active vs placebo. No adverse effects.
Read on PubMed →Meta-analysis of 11 RCTs → LLLT significantly increased hair density vs sham (SMD 1.316, 95% CI 0.99–1.64). Effective in both genders.
Read on PubMed →Review of 10 RCTs → all sham-controlled studies showed statistically significant increase in hair diameter or density (p<0.01). Minimal adverse effects.
Read on PubMed →Xtrallux's latest-generation devices use an advanced design and manufacturing approach that places each VCSEL laser flat onto a flexible circuit. The result: a slimmer profile, more uniform placement, and consistent, targeted delivery of clinically established 650 nm light—with fewer connection points for dependable performance over time.

Hair regrowth follows a biological cycle, not a marketing one. Here's what's actually happening at each phase, and what you'll start to see.
Early activity begins beneath the scalp as the hair-growth cycle starts to shift. Some may notice increased shedding, which is normal: weak, miniaturized hairs are being replaced as the cycle resets.
Shedding may begin to slow. Fine new hairs may appear at the hairline and crown, an early sign that follicles affected by miniaturization are starting to produce new growth.
Hair may feel thicker and fuller. Areas of thinning may begin to show early improvements in density and coverage, though changes may still be subtle.
Results may become more noticeable over time. Discontinuing treatment may lead to a gradual return to baseline, with continued progression of hair loss over time. Continued use is necessary to support ongoing hair growth and maintain results.

The best type of cap is based on how many diodes the cap actually has. The more diodes, the more energy; the more chances you're going to be able to stop your hair loss.
This is by far and away the most powerful laser on the market today. The Xtrallux has been our device of choice because of the additional diodes.
I see it as effective in patients with early thinning, and very effective for female patients with diffuse thinning. One of the best treatments we can offer that is FDA-Cleared.
The Xtrallux laser hat is very easy to wear. Only 6 minutes every day. It's flexible, light, and you don't feel any heat or cold when you're wearing it.
Physicians are independent practitioners. Statements reflect their professional opinions and clinical experience. Individual results vary.
All three models are FDA-cleared. The difference is density: more diodes mean more coverage and more visible results, faster.

Xtrallux is a family-owned medical-device company founded by Carlos Piña alongside his daughters Frances and Maria. More than a decade before Xtrallux launched in 2021, the same family team introduced the very first FDA-cleared home-use laser therapy cap for hair loss.
From our Miami headquarters to clinics across the United States, Xtrallux was built on a single belief: that real, clinically-validated red-laser therapy belongs in your home, not just behind a clinic door.
