When a receding hairline or thinning hair affects you, and so far, no hair loss treatment has paid off, then it’s the perfect time to try a laser hair growth device. These at-home systems use low-level lasers to heat up the scalp tissue and encourage the hair follicles to produce more hair. They can make your hair grow back faster, increase hair count, strengthen existing hair, and prevent further hair loss. And everything it’s proved by science. For whoever suffers from hair loss or hair shedding, a laser device it’s a great treatment to recover the weekend strands, promote thickness, and stimulate hair growth. So if you want to learn more about laser treatment, how it works, how safe it is, and what are the best laser devices you can buy now, this post is for you.

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 that:

First, when laser lights penetrate the scalp and are absorbed by the hair follicles, they encourage more hair to move in the growth stage. One study actually found that LLLT stimulated hair growth in both men and women by shifting the follicles from the resting phase into the growing phase. This also made the newly grown hair thicker and denser. Another research found that low-level laser treatment can boost the scalp’s blood flow, increasing the amount of oxygen, nutrients, and vitamins received by hair follicles. This nourishes the hair, making it grow faster and healthier while reactivates the dormant hair follicles.

Do laser hair growth devices really work?

Today, one of the most successful uses of low-level laser therapy is the stimulation of hair growth in the scalp’s balding areas and the treatment of various hair loss conditions, including thinning hair, alopecia areata, and androgenic alopecia. So 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 have determined at-home laser systems to be a promising hair regrowth treatment.

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 efficacity have been confirmed and tested in clinical trials. Another major concern people have is the helmet’s circumference. Although most laser systems have been 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, so pay attention to this.

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 would be 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.

Nevertheless, all laser devices can reduce hair loss and support hair growth, so which one you choose is just a matter of preference.

What you should know before buying a laser hair growth device

Before you buy a laser hair growth device, it’s good to be aware of the following things:

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 with 5 to 25-minute sessions. Most studies were performed on periods of 6-24 weeks, and the first results were usually reported after 8 weeks. 

Do lasers work for young and aged people?

As long as your hair follicles are still alive, regardless of your age, they will be able to receive oxygen and nutrients from lasers. This boosts blood flow, and as a result, the hair will grow quicker and thicker than before. Also, the inactive hair follicles will become active again. So the short answer is definitely yes! A laser hair growth device will work 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 use 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 and does not necessarily improve the effects, using a laser device and supplements, hair products, or drugs may induce a faster recovery rate and boost the results. So yes, it's considered safe to use finasteride or minoxidil while following laser hair growth therapy. One 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?

    This 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. Otherwise, in severe cases of baldness, most likely, it won't work. The hair follicles must still be alive so that laser therapy can energize 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 wash my hair or use a special shampoo before using a laser hair growth treatment?

    Not necessarily. Using a special shampoo is not mandatory, but it would be better if you'd use a shampoo that aims to stimulate hair growth than a regular one.
