The wild, wooly world of laser hair growth. In this article we dive deep into the exciting new world of laser hair cap reviews, laser hair helmets and laser hair growth devices. Our goal is to identify the best laser hair growth device for hair loss to help you start growing thicker, more beautiful hair!

Let’s face it, losing hair sucks. When you look in the mirror and see nothing but scalp where you used to have dense, beautiful hair, it’s an understandably bad feeling. Nobody wants to lose their hair, but the unfortunate truth is that over 85% of men will suffer from hair loss by age 50, as will 25% of women, according to statistics provided by the AHA.

There are, of course, many different products, techniques, and regrowth treatments available in our modern world to prevent and slow hair loss. There are even surgical techniques used to implant hair, such as hair plugs and implants.

But with so many different products on the market, figuring out what really works and what doesn’t can be very intimidating. Who’s telling the truth? Who’s just trying to sell you something? Often, it is very difficult to tell.

That’s why we’re here. In this article, we’re going to go over the hair growth devices on the market today. They have been clinically proven to restore hair without the invasiveness of surgery. Without further ado, here are the 5 best laser caps we are looking at.

LLLT (Low Laser Light Therapy), Hair Loss, and You!

Low Laser Light Therapy, or LLLT, is a method of hair regrowth that uses lasers and LED lights targeted at specific wavelengths of red light (usually around 650nM) to target skin cells and hair follicles. It will then energize them, boosting their metabolic rate and helping you regrow hair.  Typically these treatments are performed at a frequency of 2-3 sessions per week depending on the device.

Controlled clinical trials demonstrated that LLLT stimulated hair growth in both men and women, according to Low‐level laser (light) therapy (LLLT) for treatment of hair loss published in a collaboration by 5 physicians.

It’s non-invasive, and uses “cold” lasers, meaning you will not feel any kind of burning or discomfort that are typically associated with other lasers. There is also no UV radiation involved in the process.

People have used this type of hair regrowth product in clinical settings for years. It used to require booking expensive sessions at a hair restoration clinic. But given the advancements in technology over the last couple years, LLLT therapy devices are now available for you to use in the comfort of your own home.

Does it work? The evidence of LLLT.

Yes, LLLT does work. According to a an evidence based review, low level laser therapy and hair regrowth is safe and effective. The treatment can treat both Male Pattern Hair Loss (MPHL) and Female Pattern Hair Loss (FPHL), the two most common causes of hair loss and thinning for men and women.

Results can vary from person to person, and research shows that LLLT is more effective in people with moderate hair loss. Similar with most treatments, it’s better to catch it early, and treat accordingly.

Can LLLT be combined with other topical and chemical treatments?

Yes! Because LLLT only focuses on stimulating your scalp and is non-invasive, there have been no reported negative side effects when combined with other topical hair restoration programs that we could find.

What is the safety record of LLLT? Are there dangers?

According to this article and the FDA clearance publishings for these devices, they are proven to be safe and effective for the market. There were however two important safety guidelines that were recommended.

Two notes of caution we came across in our research:

First, you should avoid using LLLT if you are taking medications (or using topical medications) that increase your skin’s sensitivity to light. Despite the “cold laser” energy used in these devices, they can have negative effects when combined with these medications.

Second, you should never look directly into the lasers used in LLLT. They are delivering large amounts of energy, and your eyes, which are very vulnerable to light energy, will be negatively affected.

Is LLLT worth the cost?

Well, that depends on your level of hair loss, your budget, and your personal inclination to regrow hair. Obviously, these answers will be different for everyone, and that’s a big factor when considering hair loss treatment.

Another thing to consider is that, over the long run, these products are a great value. Especially in comparison to visiting professional hair clinics that can cost you hundreds of dollars per session.

At home laser caps have shown to be durable and reliable. You can use them for extended periods of time, even years (laser caps can last upwards of 12,000 hours or more according to Kiierr International). This means that the long-term use of these products outweigh the costs.

What products should I be looking at if I’m interested in LLLT?

There are many products out there which share the same basic design principles. Readily available online, these products are easy to buy and easy to use.

However, some of them have important differences in aspects of their design. This includes the wavelength of red light used, portability of their design and efficacy, and recommended treatment time.

We have found the top 5 LLLT device sellers on the market today, and wrote a quick review on each one. These laser cap reviews should give you a better idea of what devices, manufacturers, and products are available in order to find the best one for you.

Before using the iGrow product (or any LLLT product), they recommend that you wash your head and hair thoroughly to rid yourself of and dirt, hair products, or other contaminants. These may cause the light of the LLLT not to fully energize your skin cells and hair follicles.

Used correctly and on the recommended regimen of 20 minutes every other day, you will see the difference in your hair within 3 months. You can continue the treatment indefinitely, until you’ve achieved the results you want.
