A man in a dark green t-shirt stands in a bathroom looking at his reflection, touching his hair wondering if a red light therapy cap could help his hair growth.

You Notice It Before
Anyone Else Does.

Maybe it's your hairline. Maybe it's the thinning around the crown. Maybe it's seeing more scalp than you remember.

Either way, once you start noticing it... it's hard to stop looking.

A Simple Way to Support Your Hair at Home.

The Grounded Kiwi Red Light Therapy Cap gives you targeted red and near-infrared light therapy for your scalp — without drugs, needles or a complicated routine.

What’s Happening Beneath the Cap

More Cellular Energy
Red light supports ATP production — giving your cells more energy to do their work.
feature-item-2
Better Blood Flow
Supports circulation to the scalp, helping deliver what your hair follicles need.
feature-item-3
A Calmer Scalp
Helps reduce inflammation, creating a healthier environment for your scalp.

Your Scalp Isn't One Layer. So Why Treat It Like One?

The Grounded Kiwi Red Light Therapy Cap combines two wavelengths—660nm Red Light and 850nm Near-Infrared Light—designed to reach different layers beneath the surface.

Frequently Asked Questions

Still Wondering If It's Right for You?

Does red light therapy actually work for hair?

Red light therapy is based on photobiomodulation — a growing body of published research into how specific light wavelengths interact with your cells and support processes like circulation and cellular activity.

Here's what the research points to:

Targets Cellular Function: Studies on photobiomodulation have looked at how red and near-infrared wavelengths interact with cells to support natural processes, including at the hair follicle level.

Wavelength Matters: Research in this space consistently focuses on specific wavelength ranges — like the 660nm and 850nm used in this cap — rather than any red-coloured light.

Consistency Is Key: The research points to consistent use mattering more than any single session — this isn't a one-off fix, it's a routine that builds over time.

We won't tell you it's guaranteed to work, because results vary from person to person — but it's a legitimate, actively studied approach to supporting your scalp routine at home.

Will it fit comfortably and work with the hair I already have?

Yes. A few things make it work across different hair types:

Adjustable, hands-free fit: designed to sit securely over the whole scalp regardless of hair length.

Works over any hair type: long, short, thinning or coloured hair doesn't change how the light reaches your scalp.

No holding required: once it's on, your hands are free — wear it while you relax, work, or watch TV.

How long until I notice a difference?

There's no single timeframe we can promise, because it depends on the person. Here's how it generally breaks down:

Some things are immediate: warmth or a sense of relaxation during a session, for example.

Other changes build over time: anything related to hair and scalp health tends to be gradual, developing over weeks of consistent use rather than overnight.

Consistency beats intensity: a shorter session done regularly is more useful than one long session done occasionally.

We'd rather set that expectation honestly upfront than have you disappointed a week in.

Is $289.99 worth it?

Here's how it breaks down:

Cost per day: around $0.79 a day over a year of regular use — less than a coffee.

What's included: certified components (CE, FCC, RoHS), a remote control, and a 12-month warranty.

What you're avoiding: repeat clinic appointments and the ongoing cost that comes with them.

It's a one-off cost for something built to be used for years, not a single session.

What if it doesn't work for me?

We'd rather you ask this before buying than feel stuck after. Here's where you stand if it's not the right fit:

Easy Local Returns: Returns go straight to our New Plymouth showroom — no overseas warehouses, no chasing a seller who's gone quiet.

Real People to Talk To First: Before you even get to that point, our NZ team is happy to talk through how you're using it, expected timeframes, and whether you're using it consistently enough to give it a fair shot — sometimes the fix is in the routine, not the device.

We'd Rather You Buy the Right Thing: If it turns out this cap genuinely isn't suited to what you need, we'd rather help you figure that out than have you stuck with something that doesn't work for you.

The Red Light and Heat Strap IS NOT a 'New Fad Gimmick', It Really Works!

I was really sceptical about this new 'Red Light' tech when I first started seeing it advertised on the internet - just another 'new fad gimmick stuff'. But after looking into it over the while, I decided to give it a try because of long term pain and aches in my knees and recently forming pain in my left elbow. It's my health so I've got to look at new ideas away from the big pharma industry. I used to use Castor Oil and it works, but it's messy. For me, the 'Red Light and Heat Strap' is as advertised - 'One Strap for Every Ache'. It doesn't 'make everything disappear' as yet. What it does do is give me a day or 2 pain relief in my knees, elbow and neck! And that's generally from the low setting on light/warmth mode and the vibrate/massage mode on low and sometimes without. When it aches, I strap it on and turn it on ANYWHERE I'm at. I'm surprised how long the battery lasts as well. It's making a huge difference to my life through the day and at nights, I don't have gnawing pain constantly keeping me awake through the night. I'm actually really impressed with this 'Red Light Tech' and so glad I made the move to invest in this product from GroundedKiwi! Sometimes, you've got to spend good money to get the results over buying cheap gimmick junk the breaks or was never going to work at all.

Thanks for such a detailed review, Max. Glad you took the time to look into it before buying, and that the red light and heat wrap has been easy to use on low with the massage mode when you want it. Battery life getting a mention is useful for other customers too. – Blake

Wonder strap

This is the second one I have purchased and I use both every day on my arthritic toes etc (and my horse).

A second strap, used every day by you and your horse, is a wonderful vote of confidence. Thanks for coming back to us for another one. We're glad it's such a favourite in your household. - Blake

It's wonderful to know it meets your needs for relaxation and therapeutic benefits. If you require additional wraps, we are happy to assist you with your next purchase. Thank you for sharing your positive experience with our product from GroundedKiwi.nz, and we look forward to supporting your wellness and equine care routines with our innovative therapy solutions.

heated massage strap

I have only been using this product going on 2 weeks, can't wait to feel the results 😊.
Each time when using it after 5 minutes I am having to turn it down as it gets very hot.

Hi Megan

Thank you so much for sharing your early experience with us. We are excited for you to start feeling those wonderful results as you continue your routine.

Our strap is designed with three distinct heat settings—High, Medium, and Low—so you can easily tailor the temperature to your comfort. High heat is brilliant for rapid initial warming, but because it penetrates deeply to boost circulation, it is very common to lower it after a few minutes once your muscles are warmed up.

Our Tip: To avoid having to interrupt your relaxing session, try cycling down to the Low or Medium heat setting after your first few minutes of use, or wear a thin cotton layer underneath to keep the heat feeling gentle and soothing throughout.

Thank you again for your support and feedback.

Warm regards,

– Blake

Another amazing product by GroundedKiwi

Another fantastic product from Grounded Kiwi. I've recently purchased their red light therapy belt to use on my ankle for tissue healing and inflammation, and again I'm very impressed with the quality and ease of use.

I'm a returning Grounded Kiwi customer because I absolutely love their products, and I've always found them to be a trustworthy, knowledgeable, and a reliable NZ-owned company.

I love supporting local businesses, especially ones that genuinely care about the quality of their products and customer experience. Highly recommended! 😊 Thanks again Grounded Kiwi Team

Hi Claire

Thank you so much for your loyal support and for sharing your experience with us.
We are delighted to hear that the red light joint wrap is providing targeted photobiomodulation to assist your ankle. Harnessing both red (660nm) and deep-penetrating near-infrared (850nm) wavelengths helps boost mitochondrial ATP energy, stimulate local circulation, and support deep tissue recovery right where you need it. As a proud NZ-owned business, hearing that you trust our quality and targeted cellular health tools means everything to our team.

Thank you again for choosing to support local and for being such a valued part of the Grounded Kiwi community.

Warm regards,

I really like the red light therapy joint wrap, I

I really like the red light therapy joint wrap, I love that it has infra red also, I haven't been consistent in using it , but today my knee was sore so I put it on and haven't had any problems, the only bad thing is it's not rechargeable and I have to sit and wait, so need a power bank to walk around with it otherwise I would've given 5 stars

Thanks for the honest review, Diana. It's good to hear you've been trying the red light therapy joint wrap, and fair point about it needing mains power rather than a rechargeable battery — a power bank is a practical workaround when you want to move about. We're a NZ family business and always happy to chat if you want a hand with setup, at hello@groundedkiwi.nz.

Wonderful sturdy pro version red light!

Wonderful quality sturdy pro version red light! Ordered on a Monday night was delivered to the South Island address Wednesday morning! Having purchased previous items I have no hesitation in recommending this NZ company.

What a nice review to read, thank you. Monday night to Wednesday morning in the South Island is about as quick as it gets, and it's great to hear the Pro panel feels as solid as you'd hoped. We really appreciate you coming back to a local Kiwi business, and if you ever want to chat about it, we're only an email or phone call away.

Great tool

Very versatile and easy to use. Battery time is about 2 hours on the highest settings.
If using highest settings be careful of burning the skin and do not use longer than 20min on one area without hours between.

Thanks, Linda, this is really useful for other customers. Knowing you get about two hours of battery on the highest setting helps people plan, and your reminder to go carefully with the heat on one spot is a sensible one. If you ever have questions about your red light and heat wrap, we're a Kiwi family business and always glad to have a chat.

I have a really painful knee

I have a painful knee. I’ve been using this for 3 days now and really notice the difference! My knee pain has improved by about 70%! I highly recommend this. It’s made such a difference in such a short period of time. I’ve been on pain relief, tried knee rubs and straps. I’m so pleased I decided to try this!

Thanks for writing, Julia. It sounds like you'd tried a few things before this, so we really appreciate you taking the time to share how you've been getting on with the strap. We're a family-run NZ business and always happy to chat, so drop us a line at hello@groundedkiwi.nz any time. All the best.

Bought the therapy pad for our ageing Lab he

Bought the therapy pad for our ageing Lab he loves it as soon as he sees it he stands ready for it to be put on. Have notice that he is walking freely.
And the humans love it too.

Thanks for sharing how your Lab has taken to the Red Light Therapy Pad, Barbara. We love the picture of him standing ready the moment he sees it coming out. It's good to hear the humans in the house have claimed a turn too.

So far so good it's a pretty good gadget just wish I'd remember to use it every night

So far so good is a fine start, Pete, and thanks for giving the heated shoulder massager a go. Remembering to use a new gadget every night is something plenty of us can relate to. Maybe keeping it by your favourite chair will help it become part of the evening.

Has helped with pain relief of my dogs injury and I also use it for my own back and hip pain. It works.

I swear the ringing in my ears is less and less

I swear the ringing in my ears is less and less and I'm hearing a lot better. I also use them when I have a headache and I believe they go very quickly. It could be a placebo effect but I'll take it because I am sure they have made a positive difference in the two weeks I have been using them

Thanks for taking the time to write about your first two weeks with the earbuds, Lani. We appreciate you sharing your experience so honestly. It's good to hear you're pleased with them.

Love this product

Love this product. It's so versatile, convenient and so simple to use. I use it to on my wrist, neck, knee ankle, just about anywhere. I pop it in my bag and take it with me to work or physio. Great for muscle recovery, sore joints and soft tissue injury recovery.

Wrist, neck, knee, ankle and off to work in your bag, Lani, the strap is certainly earning its keep. Thanks for sharing how you use your red light and heat wrap. It's great to hear you find it so simple and convenient.

Improved Mobility

I have been using every day for 20mins on my right hip & noticing a big relief from pain & stiffness. I also have a grounding mat on the bed, am taking herbal supplements & have better mobility most days. Highly recommend.

Twenty minutes a day is a good steady routine, Donna, and we're pleased the hip belt has fitted into it. Thanks for taking the time to share your experience. We appreciate you recommending the Red Light & Vibration Hip Belt.

Infer-red and vibration lumbar belt

I am very pleased with the lumbar heat and vibration belt. I have had a degenerative lower back issue for a few years now, and this product has given more relief than anything I have tried to date. Would recommend to anyone with lower back pain.

Hi Kevin,

Thank you so much for taking the time to share this. Dealing with a long-term lower back issue can be so challenging, so hearing that our recovery belt has provided more relief than anything else you've tried truly means the world to us.

Knowing it's making a real difference in your day-to-day comfort is exactly why we do what we do. We really appreciate your support and your recommendation!

Happy Grounding,

Not bad but no timer

Not bad but no timer. Difficult for us. Sometimes we forget to time and when we need to start. One more thing, I don't know, how many minutes actually to charge. According to the booklet, just 3 minutes. But it's last 5 minutes I think or less. The instructions not really complete.

Hi Norlela

Thank you for your feedback. We are glad to hear the strap is working well overall, but we hear you regarding the timing and battery instructions.

The strap features a built-in auto shut-off safety feature, but we understand having a visible timer display would make tracking your sessions much easier. Regarding charging, the unit requires a full charge—typically 2 to 3 hours via the USB cable until the indicator light changes—rather than 3 minutes. A full charge will then provide multiple full treatment sessions. We appreciate you pointing out the ambiguity in the manual so we can update it.

Our Tip: For consistent daily relief without the guesswork, plug the strap in to charge fully after every few uses, and use your phone's built-in timer or alarm to notify you when your desired session time is up.

Thank you again for helping us improve our instructions and product details.

Warm regards,

– Blake

I originally brought it for my knee, it gave some relief, but doesn't sit properly, it's really good on my wrist when hands get stiff and sore, I've recently seen the knee one and will purchase it when I can afford it, definitely helps ease the pain.

Hi Diana, thank you so much for your support and for sharing your experience! We're glad the strap helps with your wrist pain, and we look forward to assisting you with the knee one in the future.
