Common questions
How is GlowRoot different from other scalp brushes?
It does 4 things at once: red light, blue light, tonic right at the roots through 7 metal tips, and gentle vibration. The tonic is water-based, so your hair doesn't get greasy. And the brush is covered by our 1-year warranty.
How soon will I see a difference?
Your scalp can feel fresh after the first use, and your hair stays light, not greasy. Give the routine a fair try: you have 90 days to decide. Results vary.
What's in the tonic?
A water-based tonic with rosemary leaf, pumpkin seed, tea tree and lavender. The full ingredient list is printed on the bottle label.
Will it work on all hair types?
Yes: straight, wavy, curly, fine or thick. On long or very curly hair, lift the brush and move it section by section instead of dragging it.
Can I use it with my other products?
Yes. You can use your own light, water-based tonic in the tank. Don't put thick oils in the tank. If you use a medicine like minoxidil, ask your doctor about timing.
What happens if I stop using it?
It works like any routine: the look lasts as long as you keep it up.
Is there a money-back guarantee?
Yes. 90 days from delivery, even if used. Email us. In the US we send a free prepaid return label for devices and items of US$50 or more. In Canada, Australia and New Zealand you pay the return shipping (we email the address after approval). Items under US$50: no need to send them back. The tonic is covered even if it's open, and you keep it. Full refund. One guarantee refund per customer per product. It's a one-time purchase, so there's nothing to cancel.
How long does the battery last?
It's rechargeable, and the guide in the box shows how many sessions you get per charge. Keep it out of the shower. Only the tank gets rinsed, once a week.
Who should not use it?
Skip it if you are pregnant, have a light-sensitive condition, a pacemaker, or broken skin on your scalp. Don't shine the lights into your eyes.
When will my order arrive?
We ship to the US, Canada, Australia and New Zealand, with tracking. Orders ship in 1–3 business days. United States: arrives in 7–12 business days (Alaska and Hawaii: up to 5 extra).
