Four Wavelengths. One Considered Scalp-Care Routine.

Introducing the RoseLume H-MAX, a wearable light-based scalp-care device designed to bring advanced optical technology into your everyday routine.

Combining red light, blue light, laser light and near-infrared light in a lightweight cap, H-MAX provides a convenient way to incorporate dedicated scalp care into your lifestyle.

Whether you’re relaxing at home, reading or taking a break, its comfortable design and built-in automatic timer make regular use straightforward.

Light technology

Four wavelengths, working side by side

Each wavelength has different optical characteristics. H-MAX brings four of them together in one cap so that the whole scalp area is covered during a single session.

430 nm
Blue light · LED
Visible blue light at the short end of the H-MAX range. Shorter wavelengths are absorbed closer to the surface than red or near-infrared light.
630 nm
Red light · LED
Visible red light, one of the bands most commonly used in low-level light devices.
650 nm
Laser · Laser diode
Laser diodes emit a narrower, more directional beam than LEDs. The source lists a beam angle below 30° for the laser sources.
850 nm
Near-infrared light · LED
Invisible to the eye. Near-infrared has a longer wavelength than visible red light.

Technology

100 laser diodes and 100 LEDs

Inside the cap, 100 laser diodes at 650 nm sit alongside 100 three-wavelength LEDs covering 430 nm, 630 nm and 850 nm.

They are arranged in a radial, high-density pattern across the crown so that light is spread across the scalp area rather than concentrated in a few spots.

Coverage

Designed to cover the whole scalp area

The light unit follows the shape of the head, with emitters running from the front hairline to the crown.

Comfort

Light enough to forget you’re wearing it

The H-MAX light unit weighs about 195 g, or about 300 g fitted in the supplied baseball cap.

It is designed to sit inside everyday hats, including baseball caps and bucket hats, so your routine can fit around your day.

Everyday use

Wear it while you work, read or rest

Because H-MAX is hands-free, a session can run while you get on with something else.

The source listing also describes running it from a power bank. We are confirming the supported power-bank output with the manufacturer.

Automatic timer

Twenty minutes, then it switches itself off

Every session is timed. After 20 minutes, H-MAX switches the light off automatically. There is no need to watch the clock or remember to turn it off.

Getting started

How to use H-MAX
