If you are experiencing a receding hairline or thinning hair, it’s a good time to try the best laser hair growth devices. These at-home systems use the energy emitted by low-level lasers to heat the scalp tissues and target the hair growth process. This triggers biochemical changes within body cells, encouraging follicles to produce more hair. In other words, laser devices can make hair to grow faster, increase hair count, strengthen existing hair, and prevent further hair loss. And it’s all proved by science!

Laser hair growth devices are an effective alternative for those whose condition hasn’t been improved by standard treatments — even researchers state the same. Since lasers work deep in the skin layers, they are more likely to stimulate the hair follicles, especially in people suffering from androgenic alopecia. Now keep scrolling to find the best laser hair growth devices out there. But first, let’s break down some facts.

How do laser hair growth devices work?

A laser hair growth device uses low-level laser therapy (LLLT) to stimulate the scalp and support hair follicles to produce stronger hair. More precisely, LLLT devices feature low-intensity lasers or light-emitting diodes (LEDs) that emit photons into the scalp, targeting and supporting the hair growth process. Here’s how they do it:

First, when the laser light penetrates the scalp, is absorbed by the hair follicles, encouraging them to become active and produce hair. This study found that laser therapy stimulated hair growth in both men and women by shifting the follicles from the resting phase into the growing phase. In turn, this made the newly grown hair thicker and denser.

According to another research, laser hair growth treatment boosts the scalp’s blood flow, increasing the amount of oxygen and nutrients received by hair follicles. Consequently, this nourishes the hair, making it grow faster and healthier while reactivating the dormant follicles. 

Do laser hair growth devices work?

Yes, LLLT devices can regrow your hair back, and in the right circumstances, they truly work. Multiple clinical studies have been done in this matter, and most of them determined at-home laser systems to be among the most effective non-ablative hair regrowth treatments.

What should I look for in an at-home laser hair growth device?

Most importantly, you should check whether or not the device you intend to buy is FDA cleared. This means that the system’s safety and efficacy have been approved in clinical trials.

Another major concern people have is the helmet’s circumference. Although most laser systems are built to fit everyone’s head, we’ve seen some reviewers complaining about the device’s size. This happens quite often with helmets rather than caps as they lack flexibility.

Finally, choose the device according to your goals. If you only want to target specific balding or thinning spots (like the top of your head), a laser comb device is enough. A helmet or cap that covers all your head may be more appropriate for those aiming to make their whole hair grow faster and increase its density and thickness.

What you should know before buying a laser hair growth device

This is everything you need to know if you want to buy the best laser hair growth device for you.

Do more lasers grow hair faster?

No. Thinking that more lasers will work more effectively is just a delusion. So far, it hasn’t been shown that more lasers can stimulate faster hair growth than fewer lasers. However, a hair growth device with extra lasers provides wider scalp coverage, meaning lasers can reach more balding areas, working more effectively for advanced hair loss conditions.  

How long does it take to see results with a LLLT device?

It’s believed that laser hair growth devices can increase hair density and reduce hair loss within 12 to 24 weeks if used regularly. Most studies were performed on periods of 6-24 weeks, and the first visible results were usually reported after eight weeks. 

Do lasers work for young and aged people?

The short answer is yes! A laser hair growth device works for both young and aged people. Nevertheless, the process may be slower in elders as they usually have less active hair follicles than youngers.

Quick questions

  1. Is it safe to apply finasteride or minoxidil while using a laser cap?

    It's not uncommon to use LLLT in conjunction with other hair growth treatments. Although it's not required, using a laser device and supplements, hair products, or drugs may induce a faster recovery rate and boost the results.

    Besides, it's considered safe to use finasteride or minoxidil while following laser hair growth therapy. This study published by the International Journal of Trichology found that “combining LLLT with topical minoxidil solution and oral finasteride may act synergistically to enhance hair growth.” Another research suggests that using LLLT with 5% minoxidil provides a higher recovery rate upon the lost hair than using a laser device alone. 

  2. Is it too late for me to start using a hair growth device?

    It depends entirely on your hair loss condition. But as long as you still have hair, even if it's thin and rare, laser therapy may help you. However, in severe cases of baldness, most likely, it won't work. The hair follicles must be still alive so that laser therapy can energise and boost them. For this reason, it's better to start using a laser device in the early stages of hair loss. 

  3. Do I need to use a targeted shampoo before following a laser hair growth treatment?

    Not necessarily. Using a targeted shampoo is not mandatory. However, it would be better if you do so. Compared to regular ones, hair growth products can support LLLT and improve the results in the long term.
