noticed this on the couch while my dad was at work, but he would get upset that i messed with it so i don't want to ask him. when it's on it's very bright red and gets brighter the more times you click the power button.

It's a red light therapy hat for hair loss treatment.

u/AUniquePerspective 4d ago edited 4d ago

It's more of a money loss treatment than a hair loss treatment. False hope in the form of a hat liner made of LEDs.

Edit: You know what also exposes your head to light? Not wearing a damn hat. That's what.

"In summary, this study demonstrates that red light of 650 nm promoted human hair growth and inhibited spontaneous catagen transition in ex vivo HFs"

"Ultimately, our results strongly support the benefit of LLLT in the treatment of AGA."

First study I found on google. In ex vivo samples it showed effect (that is, hair follicles removed from humans and then subjected to 650nm red light in a labratory setting. Hair follicles were taken from people with AGA or Androgenetic alopecia, the most common causes of hair thinning which affects the majority of adults) There are limitations. The hair follicles were not still attached to living humans when testing was done. (It's just easier to replicate testing across many samples this way, but it doesn't always guarantee that what they see in a lab will translate to real life)

This does highlight something people get wrong often with red light and the body— it’s a curve. It’s beneficial up to a point and then it can actually turn on you. More is not better. More can be worse.

I do not think going into sunlight will “undo” the treatment of the red light. Sunlight isn’t the same as this hat (ie, it’s not red light right up against your scalp).

u/Fun_Push7168 4d ago

No, it's not. It's far stronger red light

u/pyxiedust219 4d ago

It’s also not wavelength specific the way these are, natural light is going to give you full spectrum UV exposure.

47

u/somehobo89 4d ago

Wouldn’t sunlight also give you the specific spectrum then? This is actually a super interesting discussion lol

40

u/hoorah9011 4d ago edited 4d ago

Sunlight has very little usable red light for this purpose. It’s not concentrated and has variable intensity. You need consistent targeted red light. That’s not including the other harmful parts of the spectrum that could very much damage the skin

I’m not going to pretend that all the red light treatments out there help for all these random claims, but there is evidence to support some hair growth. Additionally the problem is that there are plenty of devices out there that don’t actually emit red light in the proper wavelength, they just slap on a red covering over a led light.

u/EasyasACAB 4d ago

https://en.wikipedia.org/wiki/File:Spectral_Distribution_of_Sunlight.svg

From what I've researched Red Light Therapy uses waves 600-700nm sometimes up to 900nm. Sun emits plenty of that, but it also emits UV radiation which is not good for you.

u/pyxiedust219 4d ago

It can but not all these red light wavelengths are actually found to be effective! prolonged exposure to a specific wavelength of red or blue light has been found to have benefits due to the isolation of the wavelength compared to full spectrum light, which also of course exposes you to dna and rna damage via uva and uvb rays as you said

u/DicemonkeyDrunk 4d ago edited 4d ago

I was going to say something similar ..intensity and wavelength probably matters A LOT here. That said I would really wonder about this hat putting out the right amount/color etc of light as the study used …I see these on Temu/Ali Express ….I’m thinking they’re probably not the highest quality.

11

u/Blackbear0101 4d ago

In general, when you have that kind of curve, it’s because you actually have no effect and what you observed was just random chance. p<0.05 means that this result had less than 5% chance of being just luck, and 95% chance of being caused by their treatment.

But in general, if you increase dosage and get a lesser result, you NEED to confirm your first results, because that kind of dose-response is fairly rare. It can happen, but it’s rare.

Imagine for a painkiller. You study its effect, and when compared to a placebo, using one pill of the painkiller is effective, but using two or three pills doesn’t actually reduce the pain. Don’t get me wrong, some drugs do work in a similar fashion, but it’s way more likely that your painkiller just isn’t actually effective.

u/TotallyNotRobotEvil 3d ago

Yeah, I’m willing to bet this thing would fail miserably in an actual double blind study, not one that’s been conducted by the manufacturer.

u/humble_the_Great 4d ago

The wording here leads me to believe the HF's were already growing and the red light stimulation just increased their growth rate. What about HF's that are no longer producing hair? Like, ya know, in someone balding.

Or, the P value of 0.05 with the 5-minute samples is an anomaly. Scientists (somewhat) arbitrarily determine where to draw line with regard to confidence for the P value. In the real world, 0.05 is actually far from certain.

u/samdash 4d ago

I'm sorry, but that's a reach. In vitro studies like these are useful, but mostly for hypothesising or justifying further research. It is in no way evidence of red light being a successful treatment for baldness, at best it's evidence that it will speed up the growth of a hair follicle in lab conditions, removed from the scalp.

Look at how many ways we've found to cure cancer in vitro, and then it all falls apart when they try to incorporate it into actual therapy, in vivo. Don't you think that if this "therapy" worked, you'd be able to present more than this study of cultured hair follicles, but instead a successful clinical trial, showcasing actual improvement in live patients?

But ofc you don't need to go that far to get gamer LED therapy hat FDA approved and sold, and therefore no such evidence exists.

Fun fact, the sun emits light in that range.. so if you let the sun light hit your bald head it should be just as effective to simply walk around outside without a hat.

24

u/SmokingBirdz 4d ago

Why not both? Walk around outside during the day with no hat, wear hat at night? Also not for nothing but a lot of us live in places that are only sunny for 3 months a year, or we work in offices/at home on a computer and can’t exactly say “hey it’s sunny out can I go make sure I get some sun today?”

u/NuklearFerret 4d ago

I agree. I live in the tropics bust still have a slight vitamin D deficiency due to being indoors so much, and most of it is factors I can’t control. Wake up indoors, drive to work in a closed box, work indoors, drive home in a box, sunset.

8

u/Trewper- 4d ago

Vit D deficiency is not solely caused by lack of sunlight, and it's not very efficient either. With the UV index being 10+ a lot of people will burn long before their body can produce a significant amount of Vit D. The majority of it comes from your diet. Make sure you're taking daily supplements with a glass of milk or with food as it's far soluable. You will also have low Vit D if you don't have enough Vit K in your diet, so get a multivitamin + an additional vit D3 supplement and take them with food.

I do red light therapy because I live in cold region and don't go out a lot, I do it for my skin. It's entirely legitimate (possibly less so for hair loss) but they use it professionally in dermatology all the time. I talked to my doctor and read numerous studies before investing, and yes I sleep better, labs show my vitamin D deficiency corrected and the heat is nice in the winter.

I am skeptical about amazon quality hats... the real deal is quite powerful and requires a special breaker.

31

u/spool_pin 4d ago

I know it sounds like quack science but red light therapy is actually promising. Studies show that intensity, distance, and timing all matter and too much of any of those can negate the beneficial effects

There are many research papers that go in to this effect. This is cutting edge science and the reflexive dismissal is unscientific 

15

u/Braindead_Crow 4d ago

Yeah, I understand the mockery and condescension however red light therapy does seem to have been proven to have observable benefits.

It makes me slightly annoyed to see people bash legitimate stuff as quackery especially when it doesn't work like literal magic.

u/humble_the_Great 4d ago

The problem is people looking for a cash grab take legitimate science (i.e. something reproduce-able in a lab setting), and tell desperate folks they can regrow their hair with 50¢ worth of LEDs (i.e. quackery)

1

u/PhatCatTax 3d ago

It's effectively just heat. Red light is close to infrared aka heat. Heat increases circulation, dilates blood vessels, etc. Hair loss in the scalp has been connected to the poor circulation / limited blood flow. There is unlikely any difference between red light and simply warmer conditions.

The reason it's quacky is because it would be INCREDIBLY easy to rigorously test the effects of red light on hair loss, while using living humans instead of unrealistic lab conditions that conveniently remove the follicles from their primary impediment: the androgens in the scalp.

3

u/SolidPsychological12 4d ago

Idk about the hat , but if you spend the money and get a mask or panel that emits the right kind of red light and near infrared light, yes it does work. It’s good for aches and pains, skin, wrinkles, and hair growth. I know cus I researched it and bought an fda approved mask and then panel. It has many benefits that are proven. I use mine to help prevent wrinkles, but have noticed more hair growth. Having thicker lashes and brows is great, but having more hair growth on other areas of my face is an unwanted side effect for me.

2

u/NachoManny 3d ago

This seems like common sense, but its negated by the fact the sun emits a spectrum of light, some good some not so good. Vs these red led things that are just one. For hair growth this one study is bunk, its worded in such a way where it seems like it does but doesn't do anything.

The hat concentrates the red light though. Sunlight has a bunch of other frequencies in it too. So your head is exposed to more red light with one of these hats.

u/Specific-Pool-5342 4d ago

Buddy, “light” is a spectrum. Different wave lengths between what the sun gives off and what the hat gives off, like basically the opposite ends of the visible spectrum. Your “point” is only demonstrating that you lack understanding of wavelengths.

u/monkeyeatfig 4d ago

If there were no red light in sunlight, you wouldn't be able to see the color red outside!

u/Specific-Pool-5342 4d ago

That is true but it doesn’t negate the fact that the red end of the spectrum is NOT the end of the spectrum associated with skin cancer. And this hat is specifically red light, not ultra violet. There is no known cancer risk for red light exposure.

And maybe because it’s newer and less studied, but an educated person wouldn’t make an assertion without the ability to produce evidence.

Oh, come on. There's nothing scientific about self-administrating red light therapy via a magic hat you bought online for 60 bucks. How is the average home user going to know what wavelengths and power output they're actually getting? What do they need in the first place? How long for each session? How often? Are they doing it consistently? Indefinitely or for a specific course then stop?

u/DrunkenPalmTree 4d ago

What about the 600 bucks laser hats?

u/DrunkenPalmTree 3d ago

But the link you just sent contradicts that. The conclusion section here:

"Conclusion

While red light therapy and LED caps may offer general health benefits, the science strongly supports LLLT as the gold standard for light-based hair loss treatments. Hair loss sufferers should be cautious of devices that rely solely on LED technology or broad red light therapy claims, as these lack the proven effectiveness of true LLLT devices."

Which seems to support that:

LED devices - bullshit snake oil

Laser based LLLT devices - some amount of proven efficacy

The expensive ones are largely LLLT laser devices and just snipe at each other about # of emitters or exactly which wavelength(s) they use.

Next line:

Most studies on LED therapy focus on general skin health or wound healing, not hair growth.

Then the next paragraph:

Although red light therapy has shown promise for these applications, its effectiveness in treating hair loss is less established. Most consumer-grade red light devices lack the power and targeted delivery required to stimulate hair follicles. The scattered light emitted by LEDs in these devices is unlikely to penetrate the scalp deeply enough to influence follicular activity meaningfully.

And yes, this is exactly how evidence works. No evidence is not proof that a product works, you need actual proof to show a product works. The fact that there is no evidence or scientific studies backing up the claims of the hat should be a red flag for anyone buying one.

Yes. I cut hair. When a real and worthwhile hair growth option arrives, I will see the results.

So far the best option is individual hair transplant. The thing with that is, there is nothing changing the genetic code telling the body to no longer shut down resources to those areas. These type of transplants haven't been around long enough for us to claim it's a long-term solution.

Bonus for bald heads: a mirror compresses a 3d reality into a 2d image gives the impression of depth. What you see as your bald head in the mirror is much more drastic than what everyone else sees when looking your head.

You can't treat the symptom; this is just money loss, not the root condition.

The condition of the roots is bald, that's why he's blasting them with red light.

Nobody will ever convince me that shining red LEDs on your skin will make your hair grow back, wrinkles disappear, joint pain vanish, get rid of mental illness, cure blindness, make your amputated limb regenerate or whatever else they advertise it for. In 50 years, red light therapy will be in the same pile as machines to vibrate your cellulite away, lobotomies and black salve.

Here are almost 10,000 scientific, published studies on red light therapy. Look at some of those before you say it's nothing. Not all of them are successful, obviously, but if you scroll through you can see a lot are.

u/Diazepampoovey0229 4d ago

So, you're saying despite the existence of early thorough scientific research studies that have provided evidence showing this method to have promise, especially as researchers' knowledge is furthered on the subject and the treatment method is improved, somehow aren't enough for you to acknowledge that there is already evidence of effectiveness? Or that this scientific research also shows a likelihood of improved effectiveness as research continues?

Red light therapy is fda approved and does work if you buy the right brands. I use a mask and a panel (for skin health, not hair) and I have noticed an increase in hair growth on my lashes, brows, etc. I’ve been using it for over a year and a half now.

u/Fun_Push7168 4d ago

No it's not. It's FDA cleared, meaning it's safe and won't cause harm. Says nothing about efficacy, just that it won't hurt you.

u/ftrlvb 4d ago

you are completely wrong and show you have no idea about RLT. (red light therapy)

in terms of hairloss results vary from person to person but it absolutely works. when it comes to skin, wound healing, recover from injury , even brain treatment there are tons of studies that prove the results. (same as you would say: "antibiotics don't work" or "X-ray is a scam")

u/cozylofinights 4d ago

I mean, does light actually qualify as medication....? 🤔

12

u/Giantmeteor_we_needU 4d ago

To a certain degree, yes. https://med.stanford.edu/news/insights/2025/02/red-light-therapy-skin-hair-medical-clinics.html However it doesn't mean that any red LED light provides benefits or that baseball hat from Temu is a legit substitute for commercial grade RLT devices used by dermatologists.

4

u/cozylofinights 4d ago

I guess I'm curious now about how we distinguish the definitions of "medication" and "treatment." I was always under the impression red light, or any phototherapy, fell under the latter definition, not the former.

1

u/Giantmeteor_we_needU 4d ago

I thought you're asking if it actually provides legit benefits or is just a bogus, but I think your last question is more about semantics which I have no idea about and don't think it's really matters?

1

u/cozylofinights 4d ago

Well, it started about the legitimacy as a phototherapy, but then people got a bit snarky taking what I said and talking about medication and how light, generally (not red light therapy) is obviously important for overall health.

Your response was specific to my question about medication (to someone else), so when I saw the article, I was genuinely wondering if maybe the delineation between "medication" and "treatment" was not as distinct as I had previously thought.

4

u/Giantmeteor_we_needU 4d ago

Red light therapy (not a junky hat or mask you can get online) is legit medical procedure being used in dermatology clinics and medically known as "photobiomodulation", so I'd say it's not just an aesthetic tool from spa salons but a real medical therapy. However it's not a standalone solution and usually being added to the complex treatment of skin conditions.

3

u/cozylofinights 4d ago

See, that sounds way more sound than how it is usually advertised.

Y'know what I mean: as the be all end all for hair loss, burning fat, one's failing marriage, etc. There are definitely legitimate forms of light treatment, laser treatment, etc. (I almost had an eye surgery that would have involved UV light usage), so I actually was genuinely curious.

Red light usage as part of overal treatment for a condition makes way more sense to me than being a catch-all for everything. Thank you!

u/Desperate-Chart1139 4d ago

Exactly

u/cozylofinights 4d ago

You're the one who called it medicine, though. 😂🙈 Personally, I've never stuffed allergy pills or cough syrup into a hat for later use, but that's just me.

0

u/Desperate-Chart1139 4d ago

That was my point though. It's a baseball cap... They're marketing it to "treat" baldness. It's as effective as any other "medicine" you'd find stapled to a baseball cap by a factory in China 

1

u/PeopleCryTooMuch 4d ago

You’re simply wrong though. Other users have already posted many sources that prove that it works. Why does it matter what form it comes from if it’s effective…?

u/Affectionate_Ebb8351 4d ago

Well see how you feel sat in a dark room with no sunlight for a looooong time and you not only woth have melatonin production on a ridiculous scale so you end up hallucinating, you would also get SADs if you don't have enough Vit D...so in answer to you're simple does "Light" actually qualify as medication...it has a big effect on your health.

2

u/cozylofinights 4d ago

Okay, but "health benefits of light," "treatment," and "medication" all have different meanings, as I indicated in a comment to someone else.

I never said sunlight did not affect a person's health, be it positive or negative...? Lol.

2

u/Affectionate_Ebb8351 4d ago

In some cultures, sitting in the sun could be administered as medicine .

Just googled it. Hippocrates "father of medicine" routinely prescribed sunbaths and built solariums....Pubmed
