Description

The Red Light Hat harnesses 650nm red light, a wavelength clinically studied to support hair growth, to increase microcirculation to the scalp. More blood flow means more oxygen and nutrients reaching your follicles, creating the optimal environment for stronger, fuller, healthier hair.

We took a "bad hair day" hack and turned it into a hair growth device. 120 medical-grade LED diodes are built into a stylish, cordless baseball cap with zero EMF and flexible sizing. No bulky helmet, no wires, no setup, no cleanup. Throw it on while you answer emails, walk the dog, or make your morning matcha. Ten minutes later, you're done.

And the results speak for themselves: in our consumer testing, 93% noticed overall hair and scalp health improvements, 86% noticed hair growth, and 83% saw growth in sparse or balding areas, all within 16 weeks.*

Whether you're navigating postpartum shedding, stress, menopause, genetics, or simply protecting the hair you have, the Red Light Hat makes professional-grade scalp care as easy as getting dressed.

*Based on a survey of 28 Red Light Hat users over a 16-week period.

How to Use
  1. Fully charge the battery, then click it into place on the magnetic dots at the back of the hat.
  2. (Optional) For the ultimate “DOSE,” apply our Light-Activated Scalp Serum directly to your scalp and massage it in. The formula’s copper peptides and botanicals amplify red light results.
  3. Press and hold the power button until you hear a beep and the lights turn on.
  4. Place the hat on your head and go about your day. The battery will beep when your 10-minute session is complete.
  5. Repeat daily for 16 weeks, then maintain your results with sessions 3–4 times a week.

Very convenient and effective device!

The HigherDOSE Red Light Hat is an amazing product for hair thinning. I love that it looks just like a regular baseball cap, so I can wear it around the house or even outside. The device is fully cordless, light, and comfortable on my head. A quick 10-minute session every day is so easy to fit into my morning routine. My scalp feels energized and healthy, and I can see that my hair is shedding much less than before. This premium cap is a great investment for better hair growth. I am truly satisfied with the results!

A must have

What I like most is how simple it is. I can put it on while I’m getting things done around the house or just relaxing, so it doesn’t feel like I have to make a whole separate appointment with myself to use it. It’s also really comfortable and feels like a quality product. I’m still being consistent with it and know these things can take time, but I’m happy I decided to give it a try. Its worth the price and it really does what it says! The best thing ever!Definitely something I plan on keeping up with!

I’ve been using the red light hat daily for a month and I’m starting to see noticeable results. I had thinning of my hair in the front left side and this is the area I’ve seen the greatest improvement. I also find my hair is much softer, although I also use the red light shower head. So the combo of the two has been great for my hair.

Help for hair loss.

I love this red light cap. While I combine my treatments with minoxidil, the red light really seems to help maintain my new growth when I don’t apply the topical medication.It’s an affordable option to other red light caps.The timer shuts off at exactly 10 min. I can use it 5 or 6 times per charge.

Great fit

This hat is comfortable and after 3 weeks of use I have little baby hairs coming in all along my hairline. I have a large head, but the hat is adjustable and fits well.

Red light

As a licensed master cosmetologist with over 35 years experience, I am always on the lookout for something that can improve my customers hair and my own hair since I have always had struggles with fine hair that needs extra TLC. I was super excited to try this red light therapy hat, and have been faithfully using it every night for the past month. I can honestly say as of right now I have not seen a difference. I’m going to continue to use it. See if it just takes longer than the 30 days but I have high hopes that with continued use I might start getting some results. I have read that it is not strong enough as a medically approved red light therapy device, but like I said, I will give a more honest review after I have some more time. I love the concept and I think it’s easy to wear, I haven’t had any negative side effects. I just haven’t had any new hairs showing up anywhere as of right now.

Red light therapy

I’ve been using the HigherDose red light hat for about two weeks now, mainly targeting the front of my head where the hairline has been… let’s call it “on vacation. ” I wasn’t expecting miracles this fast, but I’m already seeing little sprouts popping up in spots that were previously smooth as a freshly waxed bowling lane. It’s honestly kind of wild. Full disclosure: I do cheat a little. The second I take the hat off, I hit the area with minoxidil like I’m stacking buffs in a video game. But between the two, something is definitely happening up there, and I’m not complaining. The hat itself is easy to use, comfortable, and makes me feel like I’m doing something futuristic for my hair, like my follicles are getting VIP access to a wellness spa. If you’re trying to give your hairline a comeback tour, this thing is worth a shot.

Very easy to use

I wasn’t sure what to expect when starting my red-light regimen, but I was definitely looking forward to trying the HigherDose hat, as I suffer from hair thinning.   I find the hat is very simple and easy to use.   It’s recommended to use it for 10 minutes per day for 16 weeks, and then 3-4 times per week thereafter.   So far, it is easy to incorporate into my nighttime routine.   I see it as “me” time to sit back and relax while I let the LED lights work their magic.   However, since this is a “baseball hat” type of device, I can also multitask and do other things while this is on my head.   The timer is automatically set for 10 minutes, and beeps when done.   So, no need to worry about setting an alarm.   It has a long battery life, as I’ve only had to recharge once in the last 3 weeks. HigherDose really does make it easy and foolproof for you to use. Occasionally, I do find that the lights make my head feel warm.   However, it is not something that will alter my use of the hat.   Also to note, I do use it in conjunction with other hair growth methods (supplements, growth serums, etc. ).  So far, I haven’t seen an impactful change in my hairline, however, with the recommended usage, I hope to see less shedding and my part filled in. Overall, I am optimistic and look forward to a lot of hair growth!

Good job!

Over the past year, I have tried various hair growth treatments, and this red light cap is one of the most convenient options I have used so far. I really like that it doesn't tie you to a charging station and doesn't force you to stay in one place. I can wear it while walking around the house, doing chores, or even going outside to run my daily errands. When using it, you feel a light, pleasant warmth, which makes the process comfortable and soothing rather than distracting. The cap itself is lightweight and comfortable, and it doesn't feel uncomfortable or heavy on your head!!! The design is similar to a regular hat, so it doesn't attract attention or cause embarrassment when worn outside. It fits well and is easy to use, which makes it much easier to stick to the treatment regimen. Sooo it's a practical addition to my hair growth routine, especially for those who value flexibility and comfort.

Wow

I’ve been using the HigherDOSE red light hat for a couple of weeks now, and I’m so impressed with the results. I started using it to support hair growth and improve scalp health, but it has exceeded my expectations in so many ways!The hat is comfortable to wear, easy to use, and fits seamlessly into my routine, which makes it super easy to stay consistent. The biggest change I’ve noticed is how much new baby hair I have now. I can clearly see so many tiny new hairs growing along my hairline and throughout my scalp, and my hair looks fuller and healthier overall. It honestly feels like my hair is getting stronger and seeing visible new growth has been so exciting and motivating. I also love the design and overall quality of this device. It feels premium  it gives me a little self-care moment every time I use it.

Highly recommend

I was excited to try Higherdose Red Light Hat for hair growth to help combat my thinning hair! At one point on was on a certain medication that unfortunately caused not only hair loss but also made my remaining hair weak. I have used this hat for a month now and I am already seeing results!! This hat is cleared by the FDA! It actually boosts scalp circulation and energizes hair follicles. The first thing I noticed was I had less fall out and a lot less breakage. My hair looks healthier and has more shine. Hair grows on average a half an inch per month. When I measured my baby hairs after a month and I delighted to see my hair had grown 3/4 of inch! The treatment time is 10 minutes and the hat has an automatic timer so you know when you're treatment is done. It's easy to clean because the red light panels easily snap off. I have been so impressed with my results so far and I am excited to continue to see results! This product was received as part of a promotion.

So relax to wear especially in winter

As a beauty educator and blogger, I’m always looking for hair tools that combine science-backed technology with real-world usability, and the HigherDOSE Red Light Hat has been a standout in my routine. From the first use, I appreciated how thoughtfully designed it is , lightweight, flexible, and comfortable enough to wear while reading, working, or relaxing, which makes consistency much easier to maintain. The hat uses red light therapy to support scalp health and encourage the appearance of fuller, healthier-looking hair. I focused on using it a few times a week, and over several weeks, I noticed reduced shedding and my hair feeling stronger at the roots. My scalp also felt more balanced and less dry, which I believe helped create a better foundation for growth. What I really love from an educational standpoint is how simple and non-invasive this approach is. There’s no heat, no pulling, and no complicated setup , just a clean, easy-to-use device that fits naturally into a self-care routine. The quality of the materials feels premium, and the portability makes it practical for both home and travel use.

I'm seeing a difference

I have been incorporating the HigherDOSE Red Light Hat into my daily routine for a few weeks now, and I’m happy with how it’s going so far. I’ve always been curious about the science behind red light therapy, specifically how it uses 650nm wavelengths to stimulate the mitochondria in our hair follicles to boost ATP production. Essentially, it’s giving your scalp the cellular energy it needs to keep hair in the growth phase longer. While I know that seeing significant new growth is a marathon, not a sprint, I’ve already noticed a difference in how much hair I’m losing. Usually, I see quite a bit of shedding in the shower, but that has slowed down considerably. It feels like the device is doing its job of stabilizing my hair follicles and strengthening them from the root. What I love most is how low-maintenance it is. It looks and feels just like a regular baseball cap, so I can wear it while I’m working or hanging out at home without feeling like I’m doing a "treatment. " The fact that it’s cordless makes it so much easier to stay consistent, which is the most important part of seeing results with this kind of technology.

Easy to use and seeing results

Over the past year or so I’ve been noticing that my hair has been shedding a lot more than usual. I was completely new to red light therapy but I’d heard great things about it, so I was excited to give the HigherDOSE Red Light Hat a try. I’ve been using it for a few weeks now, and I’m seeing some good results so far. I usually wear it in the morning while I eat breakfast, which makes it so easy to fit into my day. It feels just like wearing a regular hat and isn’t bulky or heavy. I like that it has an automatic timer so I don’t have to think about how long I’m using it. I can just put it on, relax, and go about my morning. Since using it, my hair feels a bit stronger and I’ve noticed less shedding when I brush it. I know results take time and consistency, but it feels promising so far. Overall, if you’re curious about red light therapy and want something that’s easy to use and doesn’t require a big setup, this hat is a great way to start. I’m excited to keep using it and see how my results improve over time.

Love!

I am absolutely obsessed with this red light hat from HigherDose. I have been using red light therapy on my face for quite some time so I was incredibly excited to try red light to improve my head and scalp health. It is super simple to use and you only need to wear it for ten minutes a day to notice such a difference in my hair strength and have noticed more growth and less shedding. It is also super simple to attach the battery to the hat as well as recharging it- it even comes with an adapter for every single type of outlet which is such a nice and luxurious touch. I love that it also just wears like a normal baseball cap while delivering all of the amazing red light benefits. I now absolutely could not live without this- would also make an absolutely fabulous gift for someone who is working on improving their overall hair health.

I’m so happy with the results!

I am so happy I am using HigherDose Red Light Therapy Hat to help my hair look healthier, promote new hair growth and reduce hairfall. I have incorporated the hat into my daily hair care routine and so far so good! My hair feels stronger, I have noticed lesser hair shedding in my hair brush and drain. Perimenopause takes a toll on hair health…off late I was noticing more hair fall than usual and thinning in some areas, which can be a big dent to one’s confidence and can make you self conscious. I have tried the Red Light Therapy hat and I am quite impressed the scientific reason behind how it promotes new hair growth. The red light stimulates hair follicles and increases blood circulation which helps in reduction of hair shedding, strengthen existing hair follicles and also reactivate hair follicles that are dormant. I have been using it for almost a month…though there is significant reduction in hair fall, I have also noticed very tiny new hair sprouting…although I am yet to see drastic improvement. I am sure that is also possible with continuous use. What makes it so awesome is that , I can carry on with my daily tasks while using the hat without any disruptions. I just put it on and since it is cordless, I don’t need to be stationed at one place. The hat is a winner in every possible way…just 10 minutes of use everyday and such impressive results, I am excited for better, thicker and more glorious hair!
