Does Laser Treatment Really Regrow Hair?

One of the questions often asked about laser treatment for hair regrowth is if it really works.

Well, do lasers really regrow hair?

The short answer is yes, laser treatment for hair regrowth works for most people.

Clinical studies have already established the efficacy of Low-Level Laser Therapy in treating androgenic alopecia in men and women. The laser works by revitalizing the dormant hair follicles. It is an ideal treatment option for those suffering from mild to moderate hair loss. But it may not be as effective in the case of advanced hair loss. 

Read on to learn how LLLT works, what clinical studies say, the pros and cons of this treatment, & whether you are fit for Low-Level Laser Therapy. 

The Basics

LLLT uses low-level red-light energy to regenerate lost hair. It improves blood microcirculation, promotes cellular activity, and reverses cell apoptosis (natural breakdown of cells). 

When the hair follicles are subjected to increased blood circulation, they eliminate more waste and receive more nutrients. Cells convert the light energy to ATP, a molecule that provides usable energy. Extra ATP means more energy and increased cellular activity. 

By using this energy, cells rebuild the miniaturized follicles and create a healthy environment for hair to regrow, thereby reducing the chances of hair thinning in the process.

One of the many benefits of low-level light therapy is that you don’t have to go to a clinic; you can get the treatment at home. There are many laser-based FDA-approved hair growth devices ideal for home use. These devices stimulate hair follicles at consistent power and optimum wavelength to kickstart hair regrowth. HairMax is one of the most popular brands and one of the oldest players in LLLT devices. Their laser bands could be considered their flagship products. Another favorite is iRestore, having received thumbs-ups from most customers who have reviewed it

Suppose you wonder whether any hair experts are backing low-level laser light therapy as an effective treatment for moderate hair loss. In that case, the Cleveland Clinic recommends Theradome helmets as an effective LLLT device for hair loss treatment. 

The FDA categorizes them as safe-to-use medical devices. They use medical-grade lasers to deliver the red laser lights to your scalp. Some devices use a combination of lasers and LEDs. 

What does scientific research say? 

Over the last decade, various scientific studies have been performed to determine if laser treatment for hair regrowth is effective. While there have been mixed results, they are mainly positive. Due to the inconsistent results, medical communities have concluded that laser treatment can successfully regrow hair. Still, everyone may not be the right individual, especially those at an advanced stage of hair loss. 

As per a recent study review, HairMax laser-based combs effectively increased hair density among the subjects who took the trial. 

Multiple clinical reviews have attested to the success of LLLT devices and treatment. However, like everything under the sun, low-level laser therapy also has its pros and cons. 


  • It is non-invasive
  • Painless procedure 
  • No commonly reported side effects
  • Improves hair strength reducing chances of hair loss
  • Allows multitasking during treatment
  • Manageable regular regimen time
  • Affordable in comparison to in-clinic treatment


Some people are not as optimistic about laser therapy for the following reasons:

  • Long treatment time (takes at least six months to show substantial results)
  • Comparatively expensive 
  • Not as effective for all stages of hair loss

Are you a good candidate for this treatment? 

Generally, anybody noticing a receding hairline can opt for laser hair regrowth treatment for men & women. Laser devices have proven to be most effective in the early stages of hair loss. 

However, people suffering from androgenetic alopecia show impressive results when speaking of the best candidate. LLLT promotes hair growth in females with Fitzpatrick Skin Types 1 to 4 & those who fall under the Ludwig (Savin) I-4, II-1, and II-2 classifications. Also, it is effective for women having frontal hair loss patterns. 

As for men with Fitzpatrick Skin Types 1-4 & Norwood Hamilton IIa to V classifications, the treatment seems to work best. 

Note: Low-level lasers rely on certain hair cells to function. Thus, it is not meant for people with very little hair or completely bald.


The low-level laser therapy devices for home use may seem pricier than natural home remedies or pills like Minoxidil or Finasteride. However, natural remedies may not revive the cells when your hair follicles are already at a dormant stage. Also, over-the-counter medications don’t come without side effects.  

I understand it’s not always possible to accommodate time for in-clinic treatment. So, if you want to opt for a safer and more effective way to regrow your hair, LLLT devices can be a great alternative. Moreover, they are hassle-free and come with a minimum of a 6-month trial period. iRestore helmets are industry leaders, in this case, offering a 1-year money-back guarantee (no additional charges applied).
