For most of us, losing hair can be distressing. The good news is a laser hair growth cap helps mitigate this problem.

LLLT (Low-Level Laser Treatment) uses a  laser cap for hair growth to reverse or prevent hair loss in users. The available devices can come in the form of combs and caps (which tend to look like baseball caps or helmets). When one wears the cap and turns it on, it glows with a red light. Some of the best devices claim they can help the user gain fuller and thicker hair in just over 3 months.

With so many different devices available on the market, choosing the best laser hair growth device can be challenging. One has to go through a lot of research (which might take hours or days) to come up with a few choices. 

This is where this guide and product round-up comes in. We have thoroughly researched and compiled a list of the best laser caps for hair growth currently available.

What Is Laser Hair Growth? 

This therapeutic procedure utilizes low-level laser rays to stimulate the user’s hair follicles and scalp to encourage hair growth and reduce male and female baldness pattern hair loss. Low-level lasers offer the following benefits:

  • Extends the anagen[1] period – the growth phase of the user’s hair cycle. This means the user will have a longer anagen timeline than they would otherwise have without the treatment.
  • Excites follicles in telogen[2], the transition phase, enabling them to enter into this prime phase to improve hair growth and promote fuller and healthy hair strands.
  • Reduces the speed of catagen[3], the phase that causes hair follicles to transition from active to regression. This is especially important to individuals experiencing pattern hair loss early in life.

The FDA currently approves using laser combs, helmets, laser caps, and other laser growth devices to treat androgenic alopecia or pattern hair loss.

Who Should Use Laser Hair Growth Devices?

Laser hair growth caps can be used by anyone experiencing hair loss. They can be effective for individuals with androgenic alopecia to stimulate hair growth.

It is important to note that androgenic alopecia may present differently in females and males. For example, males with the condition will usually lose hair in areas close to their hairlines or the top of the head. On the other hand, hair loss in females will present as a wider parting of the center of the hair.

While much research still needs to be done to ascertain the effectiveness of laser hair caps, combs, and other laser hair growth devices, there are enough positive results to justify additional studies.

For instance, one review[4] indicated that low-level laser systems did improve hair regrowth, including in cases where individuals had pattern baldness. Another review[5] indicated that laser hair growth device users noted improved hair regrowth after prolonged usage. A recent scientific review[6] evaluating evidence from moderate and high-quality research studies indicated that hair growth laser helmet devices were effective for pattern baldness cases and are deemed safe.

How Do Laser Hair Regrowth Systems Work?

Laser hair regrowth devices are designed to treat hair loss and encourage hair growth by improving circulation in the scalp.

The devices emit red light, low-level laser light, which penetrates the scalp and is responsible for improving blood circulation, thereby stimulating hair follicles. The result is that the follicles transition to the growth phase, leading to new hair growth. The new hair grows out healthier and thicker with this laser light therapy treatment.

This is a tool for treating pattern baldness (androgenic alopecia). The Kiierr hair growth laser helmet looks like a normal baseball cap, with the major difference being that it has a medical-grade laser diode underneath. The diodes emit laser rays that penetrate the user’s scalp to promote hair regrowth, eliminate hair loss or keep it at a minimum.

The cap is lightweight, making it easy to carry with you and use. The user can utilize it anytime, anywhere –  at work, at home, in their car, or even while running errands.

On top of this, it is cleared by the FDA as a treatment for thinning hair and hair loss. The Kiierr laser cap comes in two varieties – one with 148 medical-grade laser diodes and the other with 272 diodes. While they are the same in function, the latter has more diodes and thus is larger, covers a bigger surface area, and is pricier.

illumiflow 272 Pro Laser Cap

The Illumiflow 272 Pro cap comes with an industry-best 5-year warranty speaks volumes of the manufacturer’s confidence in the product. Apart from its durability, the automatic shutoff with voice alerts makes it a device that those with disabilities can use.

The diodes in the cap are arranged to ensure optimal laser energy output to stimulate the scalp. This ensures that the laser cap provides noticeable and good results if used correctly.

The manufacturer has a solid foundation in the LLLT industry, leading to Illumiflow caps becoming the first to be approved by the FDA. Illumiflow Pro is also approved and clinically tested as a laser device for treating pattern baldness in both females and males.

Furthermore, the treatment sessions require the user to wear the laser cap for only 6 minutes per day.

The LaserFlex inserts not only provides comfort but also conceal the cap’s internal circuitry. It also keeps the diodes clean in addition to protecting them. Thorough cap cleaning is easy because it is lined with a waterproof silicone liner.

It offers the user an option between two laser treatments. One is a constant laser light treatment for 15 minutes, and the second is a pulsating laser treatment for 30 minutes. To get the best results, the user must use one of the two treatment options three times each week.

Additionally, the cap comes with a satisfaction guarantee of one year and a limited lifetime warranty. However, it is important to note that the warranty will cover the first three years after purchase. Any repairs required afterward incur a nominal fee.

Benefits Of Lasers For Hair Loss

  • Noninvasive: – No incisions are required when using laser caps, and they do not leave scars or marks on the scalp.
  • Promoting Hair Regrowth: – The laser’s light waves from the diodes in the caps stimulate follicles to facilitate growth.
  • Preventing Hair Thinning and Loss: – Laser treatments stimulate the hair follicles and help prevent them from regressing hence helping to prevent thinning and hair loss.

How To Choose The Best Laser Hair Growth Product

Some of the factors a person should consider before buying any laser hair growth devices or products include:


The market is full of laser hair growth devices with varying price ranges. No matter a person’s budget, a good option is bound to be available.

Also, most device manufacturers offer financing options to help you purchase their products if you cannot afford to pay a one-time cash payment.


As is the case when purchasing any device, a warranty is very important. Compare the warranty of various devices on the market to choose the best. Also, ensure you read the terms of both the return policy and product warranties.

FDA Clearance And Clinical Studies

Any best laser hair growth device will have FDA clearance certificates and is clinically proven. This means that they are safe to be used, and there are studies and clinical trials providing claims that the manufacturer is making.

User Reviews And Feedback

Perhaps the single most important factor to consider is user reviews. In addition to feedback and reviews left on the manufacturer’s site, look for reviews on other third-party websites such as BBB and TrustPilot.
