The bathroom shelf

Foams, gummies, shampoos. And a routine that never sticks.

It starts with a second look in the mirror. Then the shelf fills up: a foam that goes on twice a day, gummies you forget by week two, a shampoo that mostly smells nice.

A red light cap is a different kind of routine. Nothing to rub in, nothing to swallow, nothing to rinse off. You wear it for 20 minutes while you do something else, and the hard part is keeping at it for months. So we made a cap that is easy to put on every evening.

How it works

Cap on. Button. Twenty minutes.

  1. Put it on

    Pull the soft cap over the top of your head like a beanie. Plug the USB cable into a wall adapter, a laptop or a power bank.

  2. Hold the button

    Hold it to switch on, tap it to pick a mode: steady red and infrared light, or a 10 Hz or 40 Hz pulse.

  3. Get on with your evening

    Read a chapter, watch the game, answer email. After 20 minutes the cap switches itself off.

Nothing to apply, nothing to swallow, nothing to wash off.

Inside the cap

120 LEDs, two wavelengths.

Red and infrared

120 LEDs line the six panels on the inside: red at 660 nm and infrared at 850 nm, as the maker specifies.

Three modes

Steady light, or a pulse at 10 or 40 flashes a second. One button switches between them.

A 20-minute timer

Every session ends by itself, so it sits next to a book or a show without anyone watching the clock.

USB power

5 V over USB, from a wall adapter, a laptop or a power bank. Wear it on the sofa, at the desk or at the kitchen table.

An evening routine, not another bottle.

Who it is for

For men who want a routine they can keep.

  • The reader

    Twenty minutes is a chapter. Put the cap on with the book and it is done before you look up.

  • The busy one

    Wear it through email or the first half of the game. Hands free, nothing to rinse.

  • Two caps

    One for you and one for a brother, a partner or your dad. Two caps are $299.

90 days. Keep the cap.

Email support@thatchlight.com within 90 days of delivery with your order number. We refund the full price you paid to your original payment method. You do not send the cap back: keep it or pass it on. One refund per customer.

This comes on top of any rights the law of your state gives you.

Questions

Straight answers.

What does the cap do?

It shines red (660 nm) and infrared (850 nm) light from 120 LEDs on the inside of a soft cap, for 20 minutes at a time, steady or pulsed. Every scalp is different, so instead of promises you get 90 days to try it.

Is there research on red light and thinning hair?

Yes. Researchers have published sham-controlled trials, for example a 24-week randomized trial of a home-use red light helmet in Dermatologic Surgery (2013). That study tested its own device, not this cap.

How do I use it?

Pull it on like a beanie, plug the USB cable into a wall adapter, a laptop or a power bank, hold the button to switch it on and tap to pick a mode. It switches off after 20 minutes. The manual in the box has the details.

Does it have a battery?

No. It runs over USB while it is plugged in, at 5 V / 2 A. The cable is in the box; a phone adapter rated 2 A, a laptop or a power bank does the job.

Will it fit me?

It is one size, in a soft stretch fabric, and pulls on like a beanie.

Why $179?

Laser hair helmets cost over $1,000. Ours is a different, simpler thing: a soft LED cap for $179, with free tracked shipping and 90 days to try it.

When will it arrive?

It ships within 3‑10 business days and arrives within 7‑19 business days of your order, with tracking the whole way. For Christmas, order by November 27 for the best chance.

Why does it ship from China?

Our fulfillment partner's warehouse is in China, close to where the cap is made. That keeps the price down. Every parcel is tracked the whole way.

Will I pay customs or duties on delivery?

No. Import costs are paid with the shipping, which is on us. The price at checkout is all you pay.

What if it is not for me?

Email us within 90 days of delivery with your order number. We refund the full price and you keep the cap. If it arrives faulty or damaged, we replace it or refund you. See the returns and guarantee policy.

Can I change or cancel my order?

Yes, until it ships. Email support@thatchlight.com with your order number and we cancel it for a full refund.

How can I pay?

Visa, Mastercard, American Express, Apple Pay, Google Pay, PayPal and Link, through Stripe's secure checkout. We never see your card number.

Are there reviews?

They will appear here once our first customers write them. Until then the guarantee carries the risk: if the cap is not for you within 90 days, we refund you and you keep it.

Who is behind this

A note from us.

Thatchlight is a small brand of Codext GmbH, a company in southern Germany. We wanted a red light routine that feels like part of a calm evening, not a trip to a clinic: a soft cap, one button, twenty minutes, done.

We are new, so here is what we can promise instead of reviews: plain specs, honest delivery times, a reply from a real person within one business day, and a 90-day guarantee that does not make you ship anything back across the world.

If something is not right, write to support@thatchlight.com. Codext GmbH, Frankenstraße 10, 74549 Wolpertshausen, Germany. Phone +49 7904 5203106.
