PRODUCT DESCRIPTION
Serious hair therapy, disguised as your favourite cap. Ten minutes a day is all it asks.
The Infraredi Hair Growth Hat uses a unique hybrid blend of 44 LEDs and 46 laser diodes. Both provide 650nm red light from a single wearable module. It is ARTG Listed, medical grade, zero EMF and delivers high-powered irradiance. Sessions run for 10 minutes and end automatically, so it fits into the part of your day when you are already sitting down.
The user guide describes it as designed to address hair thinning and loss, weakened follicles, slow growth, poor scalp health and androgenetic alopecia. Results vary with consistency and cause of thinning — see “Is it right for you?” below.
- 44 LEDs + 46 laser diodes, 650nm (±10nm)
- Class 1 laser
- 10-minute session with automatic shut-off
- USB-C rechargeable, 2–3 hour charge
- 197g, removable light module

How light interacts with your follicles.
Red light therapy is also called photobiomodulation: using specific wavelengths of light to influence biological activity. Light is absorbed by light-sensitive molecules in the scalp, initiating cellular responses.
Light reaches the scalp
90 sources sit inside the cap, close to the scalp. Because the cap holds them in place, the light is delivered for the full ten minutes.
Follicle cells absorb it
Light-sensitive molecules in the cells around the follicle absorb 650nm red light. Researchers study how this affects mitochondrial activity and other cell signals.
Energy for the hair cycle
ATP is the usable energy cells need for normal function. Increased energy in follicle cells is one proposed mechanism for supporting the growth phase of the hair cycle.
From cells to what you see
Hair grows slowly, so changes show over months rather than weeks. Consistent daily sessions are what the studies measured — and what the cap is designed to make easy.
LEDs + Lasers. Both at 650nm.
The Hair Growth Hat combines 44 LEDs and 46 laser diodes in one wearable module. Both provide 650nm red light.
44 LEDs — red light
LEDs spread light broadly, so 44 of them arranged across the inside of the cap bathe the whole scalp in 650nm red light — crown, temples and hairline — in a single ten-minute session.
46 laser diodes — red light
Laser diodes deliver a focused, concentrated beam of the same 650nm light. 46 of them sit alongside the LEDs, so every session combines broad coverage with targeted intensity — two light sources working together, instead of settling for one.
Wavelength, output, coverage and session time all matter — which is why the module holds all 90 sources against the scalp for the full ten minutes, every session.
The device you forget you’re wearing.
Most hair-growth devices are helmets. Hard shells, cables, ten minutes on the couch. The Hair Growth Hat is a cap. 197 grams of cotton, a light module inside, and a routine that fits into your day instead of interrupting it.

Built for wearing every day — the details that decide whether a hair device becomes a habit.
*Based on selected alternative LED and laser hair devices reviewed in September 2026. Light-source counts, session timers, inclusions and warranty terms vary by model.
A simple routine. Ten minutes a day.
Cordless sessions. Automatic shutoff. Recharges in 2–3 hours.
Put it on
Adjust the cap for a comfortable fit, with the light module sitting close to your scalp. Use on clean, dry hair.
Press and hold to start
Hold the power button for approximately three seconds. Enjoy your morning coffee, read or catch up on emails during your session.
Ten minutes. Then you’re done.
The hat switches off automatically after ten minutes. Use consistently as directed in the user guide — daily or every second day, at least 12 hours apart, no more than 7 sessions a week.
Real people. Real routines. Real hair.
This is based on an initial test group that we piloted before launch.
Hair around my crown has started to fill in. Nobody at work has any idea it is anything but a cap — I wear it on the commute and it is done before I get in.
I have tried foams and serums for years and hated the mess. Ten minutes with this on while I make breakfast is a routine I can actually keep, and my hairline looks fuller in photos.
Shedding in the shower dropped noticeably after about six weeks. Build quality is great, the battery lasts a week of sessions and the auto-off means I never overdo it.
Bought it for my husband, borrowed it myself. We alternate days. His thinning patch is less visible and my part looks less wide. Worth it for two people.
Support answered my suitability questions before I bought, shipping was two days and the 60-day trial made it a no-brainer. Kept it.
Lightweight, comfortable, and honestly looks better than most of my caps. The lights are bright but you cannot feel a thing. Photos at 12 weeks show real density difference.
Reviews are collected and verified by Okendo. Individual results vary; hair growth takes time and depends on consistent use as directed.
Honest about results. Serious about the science.
Red light around 650nm has been studied for hair growth in independent trials of LED and laser devices. The Hair Growth Hat uses that same wavelength from all 90 sources, with high-powered irradiance at the scalp.
Individual results vary.
Take a baseline photo
Same light, same angle, dry hair. This is what you compare against.
Follow the schedule
A 10-minute session daily or every second day, no more than 7 a week.
Re-take the photo
Hair grows slowly. Compare over months, not week to week.
Keep going
Continue using consistently for best results over time.
Designed for thinning, weak follicles and slow growth.
Whether your hair is thinning at the crown, receding at the front or simply not growing back the way it used to, the Hair Growth Hat is built for exactly this. Red light at 650nm, delivered to the whole scalp, ten minutes a day.
Fit. One-size cotton cap with an adjustable rear strap. Wear it so the light module sits in close, direct contact with your scalp.
