What Capillus is and how it differs from other hair restoration devices
Capillus is a wearable cap that uses low-level laser therapy (LLLT) to treat hair loss. You wear it on your head for about 30 minutes a day, and it emits red and near-infrared light wavelengths designed to stimulate hair follicles. The company markets it as a non-drug, non-surgical option for pattern baldness in both men and women.
Capillus differs from topical treatments like minoxidil (Rogaine) and oral medications like finasteride (Propecia) because you do not explore anything to your scalp or take a pill. It also differs from hair transplant surgery, which physically moves hair from one part of your scalp to another. Instead, Capillus aims to slow hair loss and regrow hair by changing the environment around existing follicles.
The company makes several versions: Capillus272 (272 laser diodes), Capillus312 (312 diodes), and Capillus82 (82 diodes, the most affordable model). The number of diodes affects how much of your scalp the device covers and how long treatment takes.
Key Takeaways
- Capillus is a wearable laser cap you wear for 30 minutes daily; it is not a medication or surgical procedure.
- The device costs between roughly $800 and $3,500 depending on the model, and most insurance plans do not cover it.
- Clinical studies show mixed results: some users see slowed hair loss or modest regrowth, but results vary widely and take months to appear.
- You must continue using it indefinitely; stopping treatment typically leads to hair loss resuming within months.
- Capillus works best for early-stage hair loss and does not work for people who are completely bald.
How laser therapy is supposed to work on hair follicles
The theory behind Capillus rests on the idea that low-level laser light can energize cells in hair follicles. Specifically, the red and near-infrared light wavelengths (typically 630 to 1000 nanometers) are thought to be absorbed by mitochondria in follicle cells, boosting energy production and moving follicles from a resting phase back into an active growth phase.
This mechanism is called photobiomodulation. The FDA has cleared some laser and light devices for treating hair loss, which means the agency found them safe and that manufacturers presented evidence of effectiveness. However, FDA clearance does not mean the device works for everyone or that it works as well as prescription medications.
The evidence for LLLT in hair loss is real but modest. Some peer-reviewed studies show that people using laser caps experienced slower hair loss or modest hair regrowth compared to people using a sham (fake) device. Other studies show no meaningful difference. The variation depends on factors like the wavelength used, the power of the light, how long and how often you use it, and the stage of your hair loss when you start.
Cost, insurance coverage, and payment options
Capillus devices range from about $800 for the Capillus82 to $3,500 for the Capillus312, depending on which model you choose. The company sometimes offers payment plans through third-party lenders, allowing you to spread the cost over 12 to 24 months with interest. Some plans charge no interest if you pay within a set period.
Most health insurance plans do not cover Capillus because it is classified as a cosmetic device rather than a medically necessary treatment. Medicare does not cover it. Some flexible spending accounts (FSAs) or health savings accounts (HSAs) may allow you to use pre-tax dollars to purchase one, but you should check your plan's rules first.
The company occasionally runs promotions or discounts, particularly around holidays. You can also find used or refurbished models online at lower prices, though buying secondhand means you lose any manufacturer warranty.
What the clinical evidence actually shows
Capillus has funded or sponsored several clinical studies on its devices. In a 2017 study published in a peer-reviewed journal, men using the Capillus272 for 26 weeks showed an average increase in hair count compared to a control group using a sham device. However, the increase was modest — roughly 20 to 30 additional hairs in a small area of the scalp — and not all participants saw results.
A 2019 study on the Capillus312 showed similar patterns: some users experienced slowed hair loss or regrowth, but the effect was gradual and took at least 16 weeks to become visible. The studies also show that results are not permanent; when people stop using the device, hair loss typically resumes within a few months.
Independent research on LLLT for hair loss is more mixed. Some studies support the approach; others find no benefit over placebo. The variation makes it hard to predict whether Capillus will work for you personally. Factors that seem to improve outcomes include starting treatment early (when you still have most of your hair), using the device consistently, and having androgenetic alopecia (pattern baldness) rather than other types of hair loss.
Who Capillus may help and who it likely will not
Capillus is most likely to help people in the early to moderate stages of hair loss who still have active hair follicles on their scalp. If you are noticing thinning or a receding hairline but still have visible hair in those areas, you are a better candidate than someone who is completely bald in certain spots.
Capillus does not work for people with scarring alopecia (hair loss caused by inflammation that destroys the follicle itself) or for people who are completely bald in an area, because the device cannot stimulate follicles that no longer exist. It also may not work as well for people with very advanced pattern baldness where follicles have already shrunk permanently.
The device is marketed for both men and women, and the underlying mechanism should theoretically work for both. However, most clinical studies have focused on men, so the evidence base for women is smaller.
How to use Capillus and what to expect in terms of timeline
You wear the Capillus cap on your head for 30 minutes per day. The device is cordless and rechargeable, so you can wear it while reading, working, or watching television. The cap has a control panel that shows battery level and treatment time remaining.
The company recommends daily use for best results. Missing days or using it sporadically reduces effectiveness. You should not expect to see results quickly; most studies show that visible changes take 16 to 26 weeks of consistent daily use. Some people see results sooner; others see no change even after months.
If you do see improvement, you must continue using the device indefinitely. Hair loss will resume if you stop treatment. This means Capillus is an ongoing commitment and an ongoing cost, unlike a one-time hair transplant.
Comparing Capillus to other hair loss treatments
Capillus is one option among several for treating pattern baldness. Minoxidil (Rogaine) is available over the counter, costs less than $100 per year, and has stronger clinical evidence behind it than LLLT. However, minoxidil requires daily process to the scalp and can cause scalp irritation in some people. Finasteride (Propecia) is a prescription pill that also has strong evidence but carries the risk of sexual side effects in a small percentage of users.
Hair transplant surgery is a one-time procedure that moves hair from areas where you have it to areas where you do not. It costs $4,000 to $15,000 or more, but results are permanent. However, transplants do not stop ongoing hair loss in non-transplanted areas, so many people combine transplants with medications like minoxidil or finasteride.
Some people use Capillus alongside minoxidil or finasteride, reasoning that combining approaches might yield better results. The evidence for this combination is limited, but there is no known interaction between LLLT and these medications.
Common questions about Capillus safety and side effects
Capillus is generally considered safe. The FDA cleared it based on safety data, and the light wavelengths used do not penetrate deeply enough to damage brain tissue or cause systemic harm. The most common side effects reported in studies are mild scalp irritation or temporary itching, which occur in a small percentage of users.
The device should not be used if you have a history of skin cancer on your scalp or if you take medications that make you sensitive to light. You should also avoid using it if you have an open wound or active infection on your scalp. If you are pregnant, the company recommends consulting a doctor before use, though there is no known mechanism by which LLLT would harm a fetus.
The device does not cause hair to fall out faster or trigger a "shedding phase" the way some medications do. If you notice increased hair loss after starting Capillus, it is likely coincidental rather than caused by the device.
Frequently Asked Questions
Does Capillus work for everyone?
No. Studies show that some users experience slowed hair loss or modest regrowth, while others see no change. Results depend on the stage of your hair loss, how consistently you use the device, and individual factors that researchers do not fully understand. Starting treatment early gives you a better chance of seeing results.
Can I use Capillus if I am already taking minoxidil or finasteride?
Yes. There is no known interaction between LLLT and these medications. Some people use Capillus alongside minoxidil or finasteride hoping for better results, though research on this combination is limited. Talk to your doctor if you want to combine treatments.
What happens if I stop using Capillus?
Hair loss typically resumes within a few months of stopping treatment. Unlike a hair transplant, which produces permanent results, Capillus requires ongoing daily use to maintain any benefit. This makes it a long-term commitment and expense.
Is Capillus covered by insurance?
Most insurance plans do not cover Capillus because it is classified as cosmetic rather than medically necessary. Medicare does not cover it. You may be able to use pre-tax dollars from a flexible spending account or health savings account if your plan permits, but you should verify with your plan administrator first.
How long does a Capillus device last?
The device itself typically lasts several years with normal use. The battery will eventually degrade and may need replacement, which the company can arrange. If the device breaks, Capillus offers a limited warranty, though the terms vary by model and purchase date.
