03 — HOW IT WORKS

How to use it

Three things happen at once, so there is nothing to put down and nothing to wash off.

  1. 01

    FILL THE DISPENSER

    Your oil, your serum, your tonic — whatever you already use. It sits inside the brush, not on your palms.

  2. 02

    BRUSH FOR FOUR MINUTES

    Sonic vibration works it down to the scalp while you brush. The red light is on the whole time.

  3. 03

    THAT’S IT

    No rinse, no towel, no second sink trip. That is the entire reason it survives past week two.

04 — SAME SESSION

Before, and four minutes later

One sitting. No weeks, no waiting, no filter. Tripod locked — same light, same angle, same part-line in both frames.

07 — STRAIGHT ANSWERS

The questions people actually ask

What does it actually feel like?

Like a scalp massage with something buzzing behind it. Most people describe a tingle that lasts a few minutes after you stop.

What does the red light actually do?

We describe the light, not its effect. The published research on red light and hair was run on FDA-cleared medical devices that cost several hundred dollars and put out far more power than any brush at this price. Ours is not one of those, so we do not quote those studies at you.

Is it safe to use on my scalp?

Yes. Start on the low setting. If your scalp is sensitive, shorter sessions are fine — there is no benefit to pushing through discomfort.

Can I use my own oil or serum?

That is the point of it. Thin heavier oils like castor 50/50 with something lighter first, or the dispenser will clog.

Will it work on my hair type?

The bristles are long enough to reach the scalp through thick, curly and coily hair. It is the scalp it is designed for, not the lengths.

How do I clean it?

Rinse the bristle head under warm water after every use. Do not submerge the body.

How long does a charge last?

[Add your measured runtime here before publishing.]

Can I use it on wet hair?

Yes, on damp hair. Do not use it in the shower.

What if I don’t like it?

Tell us inside 30 days and we refund you in full. You do not need to post it back — we cannot resell anything that has touched a scalp.

Four minutes a night. That’s the whole ask.
