Why the shower
In one study, 90% of new mothers first noticed their hair loss while washing their hair. The drain is where it starts. Now it's where you fight back, with clinical-wavelength red light, every single shower.

How it works
Stop the damage. Start the growth.
Two clinical wavelengths and a filter, working on your scalp while you shower like you always do.
660nm red light, at the surface
The wavelength range used in double-blind clinical hair studies, aimed straight at your scalp.
850nm near-infrared, deeper
Invisible light that travels further into the skin, toward the follicle where hair grows.
Hold it where you're thinning
It's handheld. Hold it over your part, crown or hairline for a few minutes, then shower like normal.
One shower, three rituals
Hair. Skin. Sleep.
Red and near-infrared light have been studied for all three. Now they're part of the shower you already take.
01 · HairThicker-looking hairLess shedding in the drain, a calmer scalp and fuller-looking hair at the part and crown.
02 · SkinA softer glowFiltered water that's kinder to skin, plus red light, the wavelength skincare devices are built on.
03 · SleepThe dark showerLights off, red on. A warm evening wind-down without the blue light that keeps you up.

Does red light in the shower actually work?
Red light therapy at 650–660nm has been studied in double-blind trials, where it increased hair counts compared with sham devices. The Shower Kit Pro puts the same red wavelength range, plus 850nm near-infrared, right above your scalp. Results depend on consistency, and you shower every day.
How long until I see results?
Softer hair and a calmer scalp come first. In clinical trials, hair gains were measurable from around 8–12 weeks, with the biggest results at 16 weeks and beyond.
Will it fit my shower?
It twists onto any standard 1/2" shower hose, the same fitting used by almost every handheld shower. Only have a fixed showerhead? [Hose + holder included / hose kit, confirm with supplier].
Why handheld instead of a fixed showerhead?
Because your scalp is the target. A fixed head lights you from across the shower. Handheld, you hold the light a few centimetres from where you're thinning, then hang it back up.
How often do I change the filter?
Every [X] months. Your first filters are free, and refills can be delivered automatically.
What if it doesn't work for me?
You're covered by our 60-day money-back guarantee. No restocking fees, no photo diaries, no hoops.
