312 Medical-Grade Laser Diodes Across Three Wavelengths
The first Capillus cap to deploy three distinct wavelengths simultaneously. 272 red lasers at 650nm activate hair follicle stem cells at 2–3mm. 40 near-infrared lasers split across 780nm and 808nm reach the mid-dermal vascular layer and subdermal tissue that red light alone has never been able to treat. Three depths. One six-minute session.
780nm — The Wavelength No Previous Capillus Device Has Included
Recent research has confirmed what the science has been pointing toward: the mid-dermal layer — between 3mm and 5mm — plays a critical role in whether follicles thrive. It's where the blood vessels and connective tissue that supply every follicle live. 780nm was selected specifically to reach this layer, improving microcirculation and structural support where it matters most. Paired with 808nm for deep subdermal treatment, the TriSpectrum addresses the full depth of the scalp for the first time.
Same 6-Minute Daily Routine. Three Times the Depth.
Sessions auto-program and shut off automatically — no timers, no watching the clock. The only thing that's changed is what happens during those six minutes. Three wavelengths treat three scalp layers simultaneously, in the same hands-free session you're already used to.

Capillus TriSpectrum
Science Meets Visible Results
Three wavelengths. Every layer treated.
The TriSpectrum uses clinically supported red and near-infrared laser light to activate follicle cells, improve scalp microcirculation, and reduce the deep inflammation that drives advanced hair loss, all in six hands-free minutes a day.
THE TECHNOLOGY
THE FOLLICLE ACTIVATOR
Red light penetrates to the follicle stem cells in the upper scalp. Absorbed by cytochrome c oxidase in mitochondria, it triggers ATP production, which is the cellular energy that keeps follicles in the growth phase longer, producing thicker, stronger hair.
THE VASCULAR BRIDGE
Near-infrared fills the biological gap between 650nm and 808nm, reaching the mid-dermal blood vessel networks that feed every follicle. Improves oxygen delivery, structural integrity, and the vascular scaffolding follicles depend on to survive. Unique to the TriSpectrum.
THE DEEP PROTECTOR
Deep NIR penetrates further than any visible light, reaching the subdermal vascular plexus. Reduces oxidative stress and the chronic low-grade inflammation that accelerates follicle miniaturization in moderate-to-advanced hair loss.
PENETRATION DEPTH MAP
See exactly where each wavelength works
650nm
Absorbed by mitochondrial enzymes in follicle cells. Boosts ATP energy production. Extends the active growth phase and reverses miniaturization.
780nm
Reaches the mid-dermal blood supply — the layer that 650nm and 808nm both miss. Improves oxygen delivery and structural support for every follicle.
808nm
Penetrates deepest of the trio. Targets the subdermal vascular plexus. Reduces deep inflammation that drives advanced hair loss.
Precision energy across the full scalp
Medical-grade laser diodes deliver precise, consistent energy at each wavelength, ensuring every treatment session reaches its biological target at therapeutic intensity, across your entire scalp.
- 272 × 650nm red light diodes for follicle activation coverage
- 20 × 780nm near-infrared diodes for mid-dermal vascular support
- 20 × 808nm deep NIR diodes for deep tissue protection
- Continuous output mode for maximum energy delivery
The only cap that reaches all three layers
Two-wavelength devices leave a biological gap in the mid-dermis between 2mm and 5mm, where blood vessels and connective tissue anchor every follicle. The TriSpectrum is the only cap that closes that gap at 780nm.
- Surface to deep: complete 0–6mm scalp coverage
- 780nm fills the gap that no two-wavelength cap can reach
- 808nm reaches the subdermal plexus deeper than any visible light
- Three mechanisms are working simultaneously in a single 6-minute session

Light Absorption
Photons at 650–808nm are absorbed by cytochrome c oxidase in follicle mitochondria, triggering the electron transport chain.
ATP Synthesis
Mitochondrial activity increases. ATP production rises, giving follicle cells the energy to divide and build hair proteins.
Anagen Re-entry
Dormant follicles return to the growth phase. The hair cycle extends. Shedding slows. Shaft diameter increases.
Vascular & Deep Support
780nm and 808nm improve microcirculation and reduce chronic inflammation, sustaining the scalp environment that allows long-term growth.
Clinical Integrity and Safety
The TriSpectrum is FDA-cleared and adds two additional wavelengths using technology validated by independent science, including a 2025 Journal of Biophotonics study confirming that the 680+780nm wavelength combination outperforms any single wavelength for hair regrowth. This drug-free, non-invasive approach has been shown to:
- Activate follicle stem cells and extend the active growth phase.
- Improve blood flow and oxygen delivery to follicles.
-Reduce the chronic scalp inflammation that accelerates hair loss.
- Promote natural regrowth of thicker, fuller hair.
There are no known adverse side effects, making Capillus Spectrum a safe and effective solution for long-term hair health.

What is the Capillus TriSpectrum?
The Capillus TriSpectrum is an FDA-cleared at-home laser cap that uses three wavelengths of light: 650nm red and both 780nm and 808nm near-infrared to support hair regrowth. Unlike single-wavelength devices, it treats hair loss at three different depths simultaneously: from the follicle surface down through the mid-dermis and into the deep scalp tissue. Treatment takes 6 minutes per day.
How is the TriSpectrum different from the Capillus Spectrum?
780nm near-infrared. This wavelength bridges the biological gap between 650nm (2–3mm penetration) and 808nm (5–6mm penetration), targeting the mid-dermis, where blood vessel networks and connective tissue structures reside. In independent comparative research, 785nm ranked as the second most effective wavelength for hair growth. The TriSpectrum is designed for patients seeking the most comprehensive photobiomodulation therapy currently available at home.
How do three wavelengths work together?
Think of your scalp as a three-layer system. The 650nm red light works at the top layer 2 to 3 millimeters deep, directly energizing the cells inside each follicle to produce more ATP, the biological energy that drives hair growth. The 780nm near-infrared reaches the middle layer, 3 to 5 millimeters, improving the blood vessel networks and structural tissue that feed follicles. The 808nm near-infrared light goes deepest, reaching 5 to 6 millimeters and targeting the subdermal vascular network, reducing chronic low-grade inflammation that accelerates hair loss over time. All three work simultaneously during your 6-minute daily session.
Why does penetration depth matter?
Hair loss is not only a follicle problem. Years before visible thinning, low-grade inflammation builds up in the tissue surrounding follicles. Blood vessels become less efficient. Connective tissue weakens. A device that only reaches 2–3mm can stimulate follicles directly, but it cannot address the deeper tissue environment driving those changes. TriSpectrum addresses both.
Is the TriSpectrum FDA-cleared?
Yes. The Capillus TriSpectrum is FDA-cleared for the treatment of androgenetic alopecia (genetic hair loss) in men and women. It has undergone FDA regulatory review and is approved as a Class II medical device for at-home hair restoration.
When will I see results?
Hair growth biology moves at the pace of hair growth cycles, which last 3–6 months. The TriSpectrum extends the active growth phase and may help improve the gradual, compound miniaturization changes that accumulate over time. Results vary based on degree of thinning, age, health status, and consistency of use.
Is this a laser or LED device?
Laser. The TriSpectrum uses medical-grade laser diodes that make direct contact with the scalp. LED panels emit broad-spectrum, non-coherent light held at a distance; power drops with every centimeter. For the stated penetration depths to be clinically meaningful, adequate power density at the scalp surface is required. Direct-contact laser diodes achieve this. Distance-based LED panels generally do not, regardless of the wavelength printed on the box.
Can I useit with minoxidil or finasteride?
The TriSpectrum is particularly well-suited for patients with moderate-to-advanced androgenetic alopecia, where single-wavelength approaches have plateaued; patients seeking the most comprehensive at-home photobiomodulation available; patients recovering from or planning hair transplant surgery; and patients combining laser therapy with other treatments who want the strongest biological foundation possible.
