Best Laser Cap for Hair Loss Reviews + Buying Guide

While hair loss is a common issue among men and women, it can have a detrimental effect on your self-esteem. It may also affect your social confidence in profound ways and even to depression, anxiety, and social phobia.

The good news is that it’s possible to reverse your hair loss in most cases or at least slow it down. And the best part is that there are so many hair growth supplements and treatments available to choose from.

Unfortunately, not everyone likes popping pills and taking supplements. If you’re one of them, you might want to try out laser caps for hair loss. These are easy to use and offer a convenient way to stop hair loss.

But can a cap with a bunch of tiny light bulbs help you regrow thicker, fuller hair? And what is the best laser cap for hair loss? Below is a list of some of the best FDA approved laser caps on the market and how they work.

What Are Laser Caps for Hair Growth & How Do They Work?

Best Laser Cap Article

Before we take a look at the best laser caps, let’s find out what these devices are and how they work. For starters, a laser cap is a device that features laser emitting diodes. And the best part is that it is FDA-approved to be safe.

So, these devices usually work on the concept of Low-Level Laser Therapy (LLLT). Apparently, the caps work by stimulating your hair roots with low-level laser energy that permeates the skin cells.

According to a 2015 study, controlled clinical trials showed that LLLT stimulated hair growth in men and women. The same study also demonstrated the LLLT therapy to be safe and effective.

However, results often take time (probably a few months), and they may differ from one individual to another.

Buying Guide – What To Look Out For?

With so many laser helmets for hair loss on the market, knowing which one is the best can be difficult. For this reason, there are a couple of things to consider to ensure you buy the right device for your needs. These include:

Number of Diodes

The number of diodes available in a laser device typically determines the overall effectiveness of the system. More number of diodes means better coverage, while fewer diodes provide lower coverage.

For instance, a device with 82 diodes will be less effective compared to one with 282 diodes. So, the more diodes, the better the laser cap.


Laser caps are built to emit lasers in wavelength. Generally, the ideal wavelength for laser helmets is between 630 and 680 nanometers, which are optimal for hair growth. Therefore, for best results, you should choose a device that uses lasers between the above range.

FDA Approval

Another factor to consider is whether the device you want to buy is FDA-cleared to be safe and effective. Luckily for you, all the above products are FDA-approved to be safe for use by both men and women.

Money-Back Guarantee

Additionally, you might want to consider if the laser cap comes with a 100% money-back guarantee for your peace of mind. You see, it may take a couple of months to notice any real results when using these caps.

So, a money-back guarantee ensures you can use the device risk-free. However, if you’re not completely satisfied, you can request a refund. Some of the best products usually come with a 6 or 7-month guarantee and some even include a warranty.


Laser helmets are either corded or cordless. Corded units usually restrict your movement because they only work when connected to a power outlet.

Cordless devices, on the other hand, are designed to be portable as they are built to use rechargeable batteries. This means you can run your errands or go for a walk while still undergoing the treatment. However, you must choose a unit that uses a long-lasting battery.

Comfortable Fit

Last but not least, you must consider if the cap you want to buy offers a comfortable fit. Some products are designed to provide you with a flexible fit, while others are one size fits most. The important thing is to ensure the laser helmet you choose provides a secure and comfortable fit.
