I tried three Capillus laser caps: Here's my honest take
- Only takes 6 minutes a day
- Three models to choose from
- Offers different wavelength options depending on the model
- Very expensive
- Easy to forget daily sessions
Hair loss is a tough subject for many people. It can impact your confidence, but its effects are often overlooked.
Since so many people deal with thinning hair, it makes sense that at-home wellness devices are getting more attention. Red light therapy (RLT) is becoming increasingly popular, and there are now plenty of laser and LED caps on the market to support hair growth.
One of them is Capillus, a well-known brand that offers everything from a basic single-wavelength cap to the advanced TriSpectrum model. Naturally, I got curious, and I wanted to see how all three Capillus caps stack up in real life, so I tried them out.
Stay tuned, because I’ll share my thoughts on their design, comfort, and technology. I’ll also explain the differences between the models and whether spending more is actually worth it.

A closer look at the Capillus cap models
The most obvious difference between the three Capillus models is their price.
CapillusPRO is the most affordable at about $1 019.40. Capillus Spectrum comes in second place at $2 159.20, and TriSpectrum is the most expensive one at $3 299.
That’s a big price difference, especially since you’re buying a high-priced hat. But price isn’t the only thing that changes. The models also differ in their wavelengths and the number of laser diodes, which are the reasons you might splurge more.
Wavelengths
The easiest way to compare the three models is by looking at their wavelengths.
CapillusPRO has one wavelength, Spectrum has two, and TriSpectrum has three. PRO uses 650nm red light. Spectrum adds 808nm near-infrared light, and TriSpectrum adds 780nm as well. So, as you move up, you’re not just paying for a different name. You’re getting a more advanced mix of light wavelengths.
Diode count
The number of laser diodes changes too, but not as much as the price. CapillusPRO has fewer diodes, while Spectrum and TriSpectrum have the same amount.
More diodes help spread the light more evenly across your scalp, so no area is missed. However, TriSpectrum has another benefit: its diodes are divided among three wavelengths. This means you get the same number of diodes as the Spectrum, but with a more varied wavelength setup.
What is the Capillus laser cap, and how does it work?
Usually, RLT cap/helmet brands use low-level laser therapy (LLLT), also known as photobiomodulation, to potentially support hair follicles. That said, there are a few ways these devices deliver light.
The most common approach combines lasers and LEDs. The idea is that lasers may provide more focused support, while LEDs offer broader coverage. Together, they work for a more even application across the scalp.
Capillus takes a different approach here. It uses laser diodes exclusively, with no LEDs. The company argues that medical-grade lasers deliver more consistent energy to the follicles. And because of that, some experts favor lasers.
Research papers suggest lasers may perform better in some cases, although the scientific community has not reached a conclusive answer.
But if we are talking specifically about Capillus, there is one thing to keep in mind. Lasers are generally more expensive to manufacture. This may explain why laser-only devices like Capillus have a higher price tag.
First impression
The Wareable team has reviewed a lot of laser caps and helmets, so when I got the Capillus collection, nothing really surprised me.
The packaging was simple. Inside, you’ll find the cap, a battery pack, a charging cable, instructions, and a protective case for storage.
What actually caught my eye was how similar all three caps look. I tried Capillus PRO, Spectrum, and TriSpectrum, and at first glance, they look almost the same. The main difference is the brand name placement on the Capillus PRO cap. I wish there were more variety between the models because it’s easy to mix them up. But maybe that’s just me.
Can you walk around while wearing it?
One of the main questions is whether you can wear the cap while doing other things. Because not everyone has time to sit on the couch for six minutes every day and do nothing else.
The good news is that Capillus made this possible. The cap connects to a small battery pack, so you don’t have to stay near a wall outlet. If you remember you left dinner in the oven, you can get up and take it out without stopping your session.
But how long does the battery last?
When I tested the cap, I had to charge the battery about every six days. Sometimes five days.
With the recommended six-minute daily sessions, that adds up to around 36 minutes of use before it needs charging again. And, being honest, I wish the battery lasted longer. I noticed that on busy days, it was easy to forget to charge it, especially when I had a lot going on.
My 6-minute daily routine
It's been a while since I wrote about laser caps. The last one I tried was the Kiierr laser cap back in May, so I was glad to test out another device.
Right away, what I liked most about Capillus was the six-minute daily session. With Kiierr, I had to sit for 30 minutes every other day. So, hey, that's a real improvement.
But that being said, I found myself forgetting to use it every day. For RLT, it really needs to become part of your daily routine. And even though I used the Capillus cap for two months, I still missed a few days here and there. It wasn't much, just a couple of days each month, but since consistency matters, I wouldn't recommend doing what I did.
Does the Capillus laser cap actually work?
This is a really tough question. After two months of trying the Capillus cap, I still can't say for sure how much it can change your hair.
Personally, I did notice less shedding, though. When I brushed my hair, there were fewer hairs left in the brush. That feels like a good sign to me, even if it's not the dramatic change some people might want.
But that is not the case for everyone. You might experience a shedding phase, where weaker hairs fall out as their follicles move back into an active growth phase. After getting through this period, you should notice that your hair feels stronger and your scalp looks healthier overall.
How long does Capillus take to work?
If you're hoping for bigger changes like thicker hair or new growth, you'll need to be patient. These things take time.
According to Capillus, you might need to check your progress after 12 months, but more obvious results could take 24 months or even longer. So, this isn't a quick fix. Since hair grows slowly, it's important to stick with it for many months.
What do Capillus users say?
People have different experiences with Capillus. Some notice their hair looks thicker and fuller after using it daily for a few months. Others say they didn't see much change, even after months of use.
Because of that, it's important to keep this in mind before spending a lot of money on a laser cap. Results aren't the same for everyone.
That's why I suggest talking to a trichologist or another hair-loss expert first. They can help you figure out what's causing your hair loss and if LLLT is right for you. They might also help you create a better treatment plan instead of just relying on one device.
Capillus vs. other laser caps
I was curious to find out how Capillus laser caps stack up against the other cap-style devices. Since the Wareable team already used several laser caps, I have a sense of what to expect.

Final verdict: Which Capillus model makes the most sense?
Everyone’s experience with hair loss or thinning is unique, so what works for one person might not work for another. I suggest seeing a specialist first. They can help figure out the cause of your hair loss and guide you before you invest in a laser cap.
But if you’re still interested in which Capillus model could work for you, here’s a simple overview.
Use Capillus PRO if:
- You don't need multiple wavelengths.
- You don’t want to splurge.
- You're happy with a six-minute daily routine.
Use Capillus Spectrum if:
- You want more than one wavelength.
- You don't want to pay the highest price for TriSpectrum.
- You want something between the basic PRO and the most advanced model.
Use Capillus TriSpectrum if:
- You want all three wavelengths Capillus offers.
- You're looking for the most advanced cap in the range.
- You don't mind spending more.
FAQ's
Results are different for everyone, so a Capillus cap might not work the same way for each person. That said, LLLT, which Capillus uses, has shown some promise in supporting hair growth. Think of it as something that may help over time rather than a quick fix for hair loss.
Capillus laser caps are FDA-cleared, not FDA-approved. These terms mean different things. FDA clearance means the device has been reviewed and found similar to another legally sold device for a specific use. FDA approval is a tougher process that looks closely at safety and effectiveness. So, FDA clearance doesn’t guarantee that the cap will work for everyone.
Hair growth is a slow process, so you probably won’t see big changes in just a few weeks. Capillus says some people notice less shedding in the first few months, with more visible results between six and twelve months.
Capillus suggests using its laser caps for six minutes each day, following the instructions for your model. It’s important to be consistent, so making those six minutes a daily habit works better than using the cap less often for longer sessions.
It depends on what you want and how much you're willing to spend. CapillusPRO is the simplest option, while Spectrum adds a second wavelength. And if you’re looking for most advanced model, TriSpectrum should be your option.
