What is a laser cap?
A laser cap is a scalp-worn device that is made of a diode laser panel that emits red and infrared lasers.
Laser caps for hair loss treatment use low-level light therapy to increase blood circulation into the affected area providing more nutrients for the hair follicle and reducing any existing inflammation. They are worn on the head for 30-60 minutes daily. Laser therapy may help delay or even prevent further hair loss.
Laser hair regrowth devices are available for purchase in a variety of formats, including helmets, caps, combs, and headbands.
How does a laser hair growth device work?
Our hair follicles pass through a hair growth cycle that consists of 3 phases: anagen, catagen, and telogen. Where the anagen phase is the active growing phase of the hair, catagen is the transition phase and telogen is the resting or the shedding phase.
Hair loss is a disrupted hair cycle, where some hair follicles pass through the telogen phase too quickly resulting in sudden hair loss, or many hair follicles that become weak and inactive leading to slow or absent hair growth.
Low-intensity laser therapy (LLLT) can reverse thinning hair by delivering low heat energy (hence the name cold laser) to your hair follicles. It stimulates cellular metabolism and increases energy production within the cell leading to better cellular health resulting in less hair loss and more hair growth. This biochemical process counteracts hair loss by prolonging the phase of the growth cycle, which reactivates dormant follicles and promotes regeneration.
Benefits of laser hair loss treatment
Laser hair loss treatment can slow down or stop hair loss in various types of thinning hair, such as androgenetic alopecia (male pattern baldness), diffuse thinning, and hereditary thinning. Benefits, including:
- Increase hair density;
- Grows new hair;
- Get rid of itching and redness on the scalp;
- Reduce inflammation and promote blood circulation in the scalp;
- The low-level laser can be used for both men and women;
- No side effects were reported;
- Low-level laser hair therapy is relatively inexpensive.

Kiierr272Premier-MD Laser Hair Cap reviews
Since I started using the laser cap and the blocking vitamins the hair loss stopped
“I have been suffering from hair loss for years and it had become a major problem. Every time I showered, there were large clumps of my hair falling out onto the floor. Thankfully after getting laser cap treatment as well as some blocking vitamin supplements this has started improving drastically. I’m happy about these results.”Thomas, MD

Hair Max — PowerFlex Laser Cap 272 reviews
Worth the money
“The device is great! It’s handheld so you can use it when you do your household chores. The flex-fit design of this product makes all the difference in comfort over other brands, especially when compared to their hard plastic counterparts which caused me pain after wearing them for too long at a time. My only complaint would be recharging, but since we’re avoiding big heavy battery packs on our devices anyway I think that’s an acceptable trade-off between power efficiency and portability.”Jeremy, AR
High-quality and comfortable product
“The PowerFlex 272 is a high-quality product that provides a comfortable head treatment. I’ve seen other devices and they don’t come close to comparing in terms of comfortability, ease-of-use, or design detail with this one. The silicone liner on this machine is so soft you’ll forget that you have a cap on your head. I’m really impressed.”Kare, NJ

iRestore Professional reviews
It works but takes time
“I was getting fed up with my thinning hair. I found out later on that it was due to PCOS and stress. After months of reading reviews online about iRestore laser therapy treatment plans, I decided to try it on myself. And I’m so glad — after just three months of use, my hair looks fuller at the top!”Kathy, TN
I found the cure
“I bought the iRestore laser cap only about 3 months ago, and the results are great. My family has noticed some changes in my appearance. The back of the head is beginning to fill in nicely with thickness returning as well. I’m so impressed.”Steve, VT
CapillusPro is a hair loss treatment that combines a laser attachment with topical products. Similar to a baseball cap, it delivers low-level laser therapy (LLLT) to the scalp to treat genetic hair loss (androgenetic alopecia) and stimulate hair growth. Laser diodes built into the inner surface of the cap provide maximum coverage of thinning areas.
These devices come in a standard size (up to 24 inches), but if you need a larger one, the company provides devices individually for a specific person.
The device should only be used for 6 minutes a day, which is much less than the aforementioned laser caps. Exceeding the recommended time or frequency will not enhance the effect of CapillusPro, and can cause negative effects (this applies to all devices). However, due to the built-in timer, you don’t have to worry about overexposure.
Getting my hair back!
“I thought it was impossible to stop hair loss, but this cap gave me hope. My thick locks are now growing back thanks to the device that doesn’t irritate my scalp. It’s like a magic cure-all for me — well worth every penny.”Barry, ND
“I’ve always known that I had thinning hair, but it wasn’t until my early thirties that the first strands started falling out. After trying every product on Drugstoreideas for weeks with little success other than making things worse instead of better, I finally decided to invest in an expensive medical-grade device. I’m happy to say after 2 years of using the device my hair loss has stopped!”Paula, CA
Are laser caps really to regrow hair? Based on scientific research
Most laser hair growth devices emit light into the scalp. Although scientific research is limited, proponents of laser therapy believe it can improve blood flow and stimulate hair growth.
Studies on the effectiveness of low-level laser therapy (LLLT) in the treatment of hair loss are presented below.
A study  was involving 100 patients with androgenetic alopecia. All participants were randomly assigned to receive LLLT on one side of the head and simulate light exposure on the other side 3 times a week for 30 minutes each over 24 weeks. After the treatment period, significantly more hair coverage was observed on the LLLT-treated scalp than on the sham-treated side. Also, a significantly greater improvement from baseline was observed in hair thickness.
The next 16-week study  involved 40 patients suffering from genetic hair loss and hair thinning. 20 people were randomly selected to receive a real LLLT system and another 20 were given a placebo system. Placebo systems were specifically designed for research. They looked identical to the real device from the outside but were built using conventional incandescent lamps instead of lasers and clinical power LEDs (650 nm wavelength) in real devices. As a result, those who used the real LLLT system experienced an impressive increase in hair growth of more than 43% on average, compared with an increase of more than 5% for those who used the fake system in the placebo group.
The following study  involved 47 women with androgenic alopecia. Two groups were created: the first was treated with red light (655 nm), the second was a placebo. Patients received treatment at home every other day for 16 weeks. The results showed a 37% increase in hair growth in the active treatment group compared to the placebo group.
The last study  included 40 patients with androgenetic alopecia. They were treated with a helmet-type home use LLLT device emitting wavelengths of 630, 650, and 660 nm, or a dummy device, for 18 minutes a day. The study lasted 24 weeks. As a result of the treatment, the LLLT group showed significantly greater hair density than the simulated device group.
Drawbacks of laser hair loss treatment
- In most cases, laser therapy is not a stand-alone approach to hair loss treatment.
It usually requires instruction in good skin and scalp care as well as a healthy diet rich in protein and vitamins.
- Individuals who opt for laser therapy must be willing to make a long-term commitment to this treatment option, as it is time-consuming (4-5 times per week for 30 minutes).
- Some patients find that the heat of the laser therapy causes discomfort during their sessions.
- Patients who are taking medications that must be taken orally (i.e., anticoagulants, antidepressants) or topically (i.e., certain acne creams) may not be suitable candidates for this treatment because it can interfere with the effectiveness of these drugs.
- Patients with scalp problems can not use laser caps. This includes psoriasis and seborrheic dermatitis. Your dermatologist must clear you for laser cap use.
Does laser cap therapy work for everyone?
Not everyone is a candidate for laser therapy. People who should avoid laser cap use include:
- Anyone under the age of 12.
Children and adolescents should not wear a laser cap for therapeutic purposes, regardless of the benefits that may be offered by treatment, because their skulls are still developing.
- Women who are pregnant or breastfeeding.
The effects of using infrared light on unborn children and infants have not been studied, so it is best to avoid laser therapy while pregnant or trying to conceive and during the first six weeks of nursing.
- People with metal implants in their heads, such as mesh from a cranioplasty or shrapnel.
Although manufacturers claim that caps are safe for these patients, anyone who has had surgery involving the brain or skull should consult with a medical professional before using a laser cap.
- People who wear a cardiac pacemaker.
Thehas not approved the use of laser therapy if you have a cardiac pacemaker, so it is best to avoid caps until further studies have been done.
- Anyone with epilepsy or other nervous system problems.
Patients with active seizure disorders should not use laser therapy because it may increase the possibility of seizures.
- Anyone who has a urinary catheter or colostomy bag in place and anyone unable to take a shower and clean the scalp area daily.
Without proper hygiene and regular cleaning, your risk of developing scalp infections increases dramatically.
- Anyone with any kind of skin disorder, such as psoriasis or acne, affects the scalp area.
Patients with skin problems should consult with their dermatologist before using a laser cap.
How to safely use laser caps?
The following precautions must be taken when using a laser cap:
- Do not look directly into the beam. It is best to put on goggles or other protective glasses.
- Use laser caps only on dry skin, and avoid contact with soap residues because these can cause unwanted fumes or accidentally burn your skin.
- It is advisable to keep the laser caps away from pets and avoid using them if you have a pet in your home.
- Never use hair growth laser caps while operating machinery, driving, jogging, or cycling.
- Keep out of reach of children and pets at all times.
Laser caps are an effective way to fight hair loss.
A laser cap with a diode laser is placed directly on the scalp, where it emits low-intensity light at a predetermined wavelength, which penetrates deep enough into the skin. This light energy stimulates the natural healing process for your hair follicles, increasing circulation around your roots and stimulating healthy hair growth.
This leads to an increase in the supply of oxygen and nutrients to your hair follicles, which boosts healthy hair growth; preventing thinning and shedding by strengthening your roots.
🧢 What are laser caps?
Laser caps that use low-level Light therapy (LLLT) in the form of red and infrared lights, lasers, and LED devices are used to stimulate hair growth. They’re intended for men and women experiencing thinning hair or bald spots on their scalp, but not total hair loss/baldness.
🤔 Are laser caps effective for hair loss?
Laser cap with 630 nm diode laser is the most effective tool because it targets the dormant hair follicle which causes hair loss and regrow new healthier hairs. This technology cures 80% of androgenetic alopecia cases. It also reduces inflammation and stimulates blood flow to the scalp.
📌 Do laser caps have side effects?
Side effects of laser caps have been studied but these are not a concern. As with any device, there is a chance of skin irritation, however, this is rare and should resolve within 24 hours if it does occur. Some users report temporary reddening or mild flaking of the skin in areas where hair loss treatments are being used. In some cases, using a product to protect the skin can help prevent these side effects.
🔎 Can you use a laser cap too much?
No, this is not recommended. The most common problem that you may notice is the appearance of red spots on your scalp. This phenomenon occurs when the device is used for a long time without stopping or short pauses between applications. In some cases, the problem may be more serious and you can get an infection in your head. It is therefore advisable to use a laser cap for hair loss treatment, not more than 60 minutes a day.
🗓 How long does a laser cap take to work?
The treatment time per day is 10 to 60 minutes, depending on the device. The first noticeable results will be visible in a few months. But keep in mind that results vary from person to person, so don’t expect a miracle from a few sessions. You will need to have regular sessions as directed by your doctor/clinic for any positive changes to be noticed.
