We won't tell you that, because no honest brand can. The GX1 is a scalp device — it supports circulation, helps your serum absorb, and keeps the scalp clear. That's the environment hair grows in. What happens on top depends on your age, genetics and how far along you are.

Scalp comfort and less flaking usually within a few weeks. Anything visible in your hair is three to six months, because that's how fast hair grows.

Once a day, five minutes. Twice a day isn't better — consistency beats intensity by a wide margin here.

Yes. The chamber takes any lightweight serum or oil. If you're on a prescription treatment, check with whoever prescribed it first.

630nm red light at this intensity is non-thermal — it doesn't heat or burn, and the device shuts off after ten minutes. Don't use it on broken skin, active infections or sunburn.

Rinse the head under a tap. It's IPX7 rated through the whole body, so there's nothing to unclog.

Two or three times a week, not daily, and clean it with isopropyl alcohol before and after. Replace it every three months.

Thirty days from delivery for a full refund. Email us and send it back — we won't ask you to prove anything or photograph anything.

No, and we won't pretend otherwise. These are grooming and scalp-care tools, not medical devices — they aren't intended to diagnose, treat, cure or prevent any disease. If you have a diagnosed scalp condition or take light-sensitising medication, check with a doctor first.
