Light source
Know the light source
Cold Laser, Daily LED and dual-wave configurations give each product its own role and format.
Masters of Light
The Science Behind NuGROWS
Light science can feel technical. NuGROWS keeps it practical, showing how each light source, product format and documented routine fit into a personal-care ritual at home.
Designed around how light is used
A clear path from light to ritual
A light-care experience is more than a wavelength. Product format, placement, session time and care rhythm help make the routine clear and natural to use.
Start with the choice that fits your day: a hands-free cap, a flexible band, a full-size or compact brush, or a personal body-care format.
Product format
Choose your way to care
Caps, flexible bands, brushes and compact pods make the routine easier to understand before you choose a model.
Care rhythm
Find a rhythm you can keep
Clear, timed sessions turn product details into a practical routine you can bring home.
Viva care system
Two light-source groups, clear routines
Choose the light-source group first, then look at the format and documented routine that fit your day.
Viva Cold Laser
A model-specific laser source
Cold Laser identifies the laser light sources used in VivaDome, VivaFit, VivaBrush Pro and VivaBrush Go.
Each model has its own format, placement and timed routine. The shared light-source name does not mean that the products have the same coverage or use instructions.
- Dome and Fit: 15 minutes, three sessions per week
- Pro and Go: 5 minutes, three sessions per week
- At least one day between scalp-care sessions
Viva Daily LED
A clear daily light routine
Daily LED identifies the LED-only VivaBrush group: VivaBrush Glow and VivaBrush Air.
Both use visible red and near-infrared LED sources in a familiar brush format with one five-minute daily session.
- Glow: 32 red LEDs + 4 near-infrared LEDs
- Air: 10 red LEDs + 2 near-infrared LEDs
- One five-minute session each day
Form follows ritual
Different formats, one considered design approach
NuGROWS pairs each light source with a format and routine chosen for the way the product is used. Compare placement and timing before you choose.
Full-coverage format
VivaDome
A hands-free cap format that brings the documented mixed-source scalp-care routine into one dedicated setup.
Flexible placement
VivaFit
A flexible band format for selected-area placement with the same clear, model-specific timing and care rhythm.
Familiar brush format
VivaBrush
Full-size and compact brush formats use parting teeth and a deliberate placement routine for scalp care.
Compact body care
AuraMacaron
A separate dual-pod format for a personal body-care and relaxation ritual, with its own documented session guidance.
Research-informed design
Research helps us design with care
Published research helps NuGROWS ask better questions about light sources, formats and everyday routines. It is one part of a considered design process.
Category research does not establish that a result reported for another device or study applies directly to a NuGROWS product or to every individual.
