Cold Laser at the core. LED for everyday care.
A useful scalp-care choice starts with the role a product will play in your week. NuGROWS puts Cold Laser at the core of its technology story and complements it with LED formats for everyday care. Across Viva, that means a choice of caps, a flexible band and brushes, each with its own documented routine.
NuGROWS brings laser technology into purpose-built personal-care products by considering optical output, operating parameters, timing and product format together. LED adds different formats and usage occasions within the same collection.
Which models use laser, LED, or both?
In the Viva catalog, Dome and Fit combine laser diodes and LEDs. Pro and Go are laser brushes. Glow and Air are LED-only brushes with red and near-infrared sources.
| Model | Format | Light sources | Session | Frequency |
|---|---|---|---|---|
| VivaDome PRO272 | Hands-free cap | 200 laser diodes + 72 LEDs | 15 minutes | Three times weekly; at least one day between sessions |
| VivaFit FLEX80 | Flexible band for a selected scalp area | 60 laser diodes + 20 LEDs | 15 minutes | Three times weekly; at least one day between sessions |
| VivaBrush Pro BRUSH32 | Full-size laser brush | 32 laser diodes | Five minutes | Three times weekly; at least one day between sessions |
| VivaBrush Go BRUSH12 | Compact laser brush | 12 laser diodes | Five minutes | Three times weekly; at least one day between sessions |
| VivaBrush Glow BRUSH32LED | Full-size LED brush | 32 red + 4 near-infrared LEDs | Five minutes | One session daily |
| VivaBrush Air BRUSH12LED | Compact LED brush | 10 red + 2 near-infrared LEDs | Five minutes | One session daily |
The laser diodes in these Viva models are specified at 655 nm ยฑ 10 nm. Dome and Fit also have LEDs at 660 nm ยฑ 10 nm. Glow and Air use 650 nm red and 850 nm near-infrared LEDs. Read these numbers as model specifications when comparing products.
Why are there 15-minute and five-minute sessions?
The session belongs to the exact model. Dome and Fit have a 15-minute standard session; Pro and Go have a five-minute standard session. All four are used three times per week, with at least one day between sessions. Glow and Air each have one five-minute daily session.
Laser models themselves have different session lengths, so the word laser alone does not tell you how long to use a product. Choose the format, then follow the timer, frequency and placement instructions for that model.
Do laser and LED support each other?
Yes. Laser and LED play complementary roles within the Viva collection. Cold Laser is the core technology story; Daily LED adds a five-minute daily-care format. The cap, band and brush choices give the range different ways to fit personal-care habits.
There are two distinctions to understand: Dome and Fit already combine laser and LED sources within a single product, while Pro/Go and Glow/Air are separate brush families with different source configurations and schedules. For a routine involving more than one device, follow the instructions applicable to the exact models and combination.
