WHY CHOOSE LASER OR LED? WE DIDN’T.
300 LASER DIODES + 200 LED LIGHT POINTS. 4 WAVELENGTHS. 12 MINUTES. Most hair caps stop at one or two wavelengths—or make you choose between laser and LED. PlasmaGLO™ Hair+ Cap combines both LED and Laser in one flexible, cordless system.
300 laser diodes at 680 nm
140 red LED light points at 625 + 655 nm
60 blue LED light points at 422 nm
500 TOTAL LIGHT SOURCES
Together, these technologies are designed to support hair density and fullness for individuals experiencing concerns such as thinning hair, reduced hair density, and a receding hairline. A flexible light panel built into the cap contours to your head for a comfortable, cordless treatment. Use for 12 minutes every other day; the cap shuts off automatically.
FDA-CLEARED FOR ANDROGENETIC ALOPECIA IN MEN AND WOMEN

LED + LASER TECHNOLOGY
WHY THIS SYSTEM IS DIFFERENT
Most caps make you choose between laser or LED. PlasmaGLO™ Hair+ Cap combines both technologies across four wavelengths in one flexible, cordless system.
- 300 LASER DIODES + 200 LED LIGHT POINTS
- TRIPLE RED: 625 / 655 / 680 nm
- 500 TOTAL LIGHT SOURCES
- BLUE MODE: 422 nm
DUAL-MODE TECHNOLOGY
TWO MODES. DISTINCT PURPOSES.
MODE 01
LASER + RED LIGHT
The PlasmaGLO Hair+ Cap begins in this mode when powered on. 300 laser diodes at 680 nm run alongside 140 red LED light points at 625 nm and 655 nm. The lasers start automatically 30 seconds after power-on, so put the cap on your head first. Designed to combat pattern hair loss by supporting thicker, fuller hair.
625 + 655 + 680 nm
MODE 02
BLUE LIGHT
A separate second mode using 60 blue LEDs at 422 nm. No laser is emitted in this mode, so you can put the cap on at your convenience. Switch modes with one short press of the control button. Designed to support overall scalp wellness.
422 nm500 TOTAL LIGHT SOURCES
See Every Wavelength
300 laser diodes and 200 LED light points work across four targeted wavelengths.
12 MINUTES. EVERY OTHER DAY.
HOW TO USE
CHARGE
Charge the device fully before first use with the supplied dual USB-C cable.
PREP AND PLACE
Make sure your scalp and hair are completely dry. Place the cap firmly and comfortably on your head, like a typical ball cap with power box at back of head.
ADJUST
Put the cap on and adjust the Velcro strap at the back until it fits snugly. The panel is already inside and held by magnets, no assembly.
START
Press and hold the control button for 1.5 seconds. One beep means the cap is on, in Mode 1.
MODE 2
For Mode 2, short-press the button once. The blue light turns on.
SESSION TIME
Each session runs 12 minutes and ends automatically with two beeps.
USAGE
Use every other day, and keep going after 16 weeks to help maintain results.
First-time users should complete the light-sensitivity test in the User Manual before a full session.

THE SCIENCE OF LIGHT
GROWTH, ILLUMINATED
How red light helps support the natural hair-growth process.
01
CELLULAR SUPPORT
Light therapy supports blood flow to the scalp, helping hair follicles get the oxygen and nutrients they need to grow.
02
GROWTH CYCLE
Combined Red Light LEDs and Lasers help stimulate and extend the follicle’s hair growth cycle, promoting thicker, fuller, healthier hair.
03
FULLER-LOOKING HAIR
Consistent use supports hair density over time, offering a non-invasive pathway to long-term results.
Consistency is key. Results vary.

Frequently Asked Questions
Most caps make you choose between laser or LED. PlasmaGLO™ Hair+ Cap combines both in one cordless system: 300 laser diodes at 680 nm, 140 red LED light points at 625 nm and 655 nm, and 60 blue LEDs at 422 nm in a separate second mode.
Mode 1 combines 300 laser diodes at 680 nm with 140 red LED light points at 625 nm and 655 nm, so you do not have to choose an all-laser or all-LED device.
Twelve minutes. The cap ends the session automatically and signals with two beeps.
Every other day. Sessions were every other day for 16 weeks in the study. Continue every-other-day use beyond 16 weeks to help maintain results; using it more often than every other day is not recommended.
Mode 1 is Laser + Red Light: 680 nm laser with 625 nm and 655 nm red LED. Mode 2 is Blue Light: 60 LEDs at 422 nm, with no laser emitted.
It is an eye-safety delay. In Mode 1 the lasers activate automatically 30 seconds after power-on, giving you time to put the cap on your head first. Never look into the inside of the pad while it is powered on.
Yes. PlasmaGLO™ Hair+ Cap is FDA-cleared for the treatment of Androgenetic Alopecia in men with Norwood-Hamilton classifications IIa–V and in women with Ludwig-Savin I-1 to I-4, II-1, II-2 or frontal patterns, in Fitzpatrick Skin Types I–IV. 510(k) NUMBER: K262183
Yes. The pad has a built-in rechargeable battery and charges over USB-C in 3 to 4 hours. You do not need to be plugged in during a session.
No. This is a single-user device and should not be shared.
No. Hair and scalp must be completely dry before every session. Follow the User Manual for all preparation and safety instructions.
Turn the device off, then spot-clean the pad with a clean cotton cloth lightly dampened with cold water. Stubborn stains can be removed with 70% alcohol. Never immerse the device, and never use acetone, solvents or abrasive cleaners. Allow it to air dry.
Anyone under 22, anyone who is pregnant or preparing for pregnancy, and anyone with the contraindications listed in Important Safety Information above. If you are unsure, speak to your physician first.

LIGHT THERAPY RESEARCH
BACKED BY SCIENCE
Published studies support low-level light therapy for pattern hair loss.
2024 | Cellular Activation & Follicle Growth
Supercharging Cellular Energy & Hair Follicle Density
5.88x Increase in Hair Follicles: In vivo studies demonstrated near-infrared light therapy significantly increased active hair follicle counts by up to 5.88-fold compared to control light sources. Boosts ATP & Cellular Bioenergy: Near-infrared light absorption by mitochondrial cytochrome c oxidase significantly stimulates ATP synthesis and reduces oxidative stress (ROS), delivering vital energy directly to hair follicles to stimulate new growth.
Choi et al., Lasers in Medical Science
2014 • Clinical Proof & Hair Regrowth
Clinically Proven Hair Density Increase in Men & Women
Significant Hair Density Boost: Multicenter, randomized, double-blind, sham-controlled trials confirmed a statistically significant average increase of 18.4 to 25.7 terminal hairs per sq. cm across tested device models after 26 weeks. Reverses Follicle Miniaturization: Macrophotographic and quantitative analysis verified the conversion of fine vellus/dormant follicles back into thick, active terminal hair follicles in both male and female pattern hair loss.
Jimenez et al., American Journal of Clinical Dermatology
2021 • Growth Cycle Extension & Gene Pathways
Prolonging the Active Growth Phase at the Molecular Level
Delays Hair Regression (Catagen): Ex vivo human hair follicle organ cultures treated with 650 nm red light remained in the active growth phase (anagen) significantly longer, delaying the regression phase (catagen). Activates Key Growth Signaling: Comprehensive RNA-sequencing (transcriptome) analysis revealed 650 nm light directly stimulates Wnt/b-catenin and cell cycle pathways, reversing the hair follicle miniaturization process.
Yang et al., Annals of Dermatology
2025 • Red + blue LED cap
Wavelength-Matched Evidence: Red + Blue LED Cap Trial
Multicenter, randomized, double-blind, sham-controlled 26-week trial of an FDA-cleared LED cap in 160 adults with AGA. Three active versions were tested: 625 + 660 nm red, 425 nm blue, and red + blue combined, with 10- minute daily treatments. Individual arms did not reach significance on the primary endpoint, but the pooled active arms showed a statistically significant increase in hair density vs sham at week 16 (p = 0.033; +28.5 hairs/cm²). Well tolerated.
