Hair Laser Therapy: What You Need to Know

Low-Level Light Therapy (LLLT), often known as laser therapy for hair loss, is a tried-and-true method that stimulates dormant hair follicles to produce new hair. The therapy, also referred to as red light therapy, makes use of a medical laser that is adjusted to a very low level, where the treatment gets its name. Low-level laser therapy includes red light therapy, soft laser therapy, cold laser therapy, photobiomodulation, and biostimulation.

The human tissue is subjected to photon radiation from the laser, which causes weaker cells to ingest the photons and then grow stronger. Due to the absence of heat, they can be utilized in clinical settings without risk and are an excellent choice for a wide variety of therapy options.

Does The Treatment with The Laser Work?

Experts found low-level laser therapy to be an effective and safe treatment for persons with male or female pattern baldness who did not react to previous therapies, according to a review of 21 trials conducted in 2016. The authors did note, however, that additional research is required to evaluate the efficacy of this treatment.

A more recent study looked into the effectiveness of many laser solutions that are readily accessible for purchase online on male and female participants experiencing hair loss. According to the authors’ research, using these products resulted in increased hair growth and thickness with fewer adverse effects.

The following are some examples of potential adverse effects:

  • Headaches
  • Acne
  • Irritation, redness, and itching of the skin

Furthermore, the authors also emphasize that much of the research they looked at had a clash of interest with firms that offer laser hair growth therapies. Because of this, the findings could be subject to bias, and additional investigation is required.

What Kinds of Conditions Can Be Remedied with Hair Laser Therapy?

What Kinds of Conditions Can Be Remedied with Hair Laser Therapy?

LLLT for treating hair loss can address various conditions in both women and men, including genetic hair loss, androgenetic alopecia, pattern balding, receding hairline, overall thinning of hair, and more. It can be used on its own as a treatment for hair loss, or you can combine it with PRP (platelet-rich plasma) therapies for hair loss to get more successful outcomes.

How Does the Treatment of Hair with Lasers Work?

In cases of androgenetic alopecia, for instance, a testosterone derivative called dihydrotestosterone plays a role in the progression of hair loss (DHT). DHT is a product of testosterone found in both men and women.  Those suffering from hair issues have testosterone levels that are high enough to convert into DHT.

Because DHT causes interference with hair follicles, it can cause them to become thinner over time, which can lead to a reduction in the production of new hair or even an end to hair growth entirely. Laser hair therapy lowers the amount of DHT in the scalp, lowering the number of factors that affect the hair follicle.

Experts believe that low-intensity laser therapy can also enhance blood circulation in the scalp and accelerate metabolism in follicles in the catagen or telogen phase, which ultimately results in the development of anagen hair.

Combining PRP And Laser Therapy

The effectiveness of laser treatment for hair loss can be increased by combining it with Platelet Rich Plasma (PRP) treatments. Platelet-rich plasma is a method of administering a significant quantity of growth elements to the scalp that utilizes the natural curative properties of the patient’s blood in a concentrated form.

The laser decreases the DHT levels that inhibit hair development. The nutrients the cells require to encourage growth are supplied by the growth factors injected directly into the scalp. When platelet-rich plasma (PRP) treatment and the efficacy of laser treatment for hair are combined, the result is very potent.

What Should One Expect During a Session of Laser Therapy for Hair Growth?

Laser treatment for hair is one of many wonderful treatments available because it is risk-free, does not involve any intrusive procedure, does not cause discomfort, and can produce visible improvements.

The normal length of an appointment is determined by whether or not PRP is included in the laser hair growth therapy. In a typical session of low-level laser therapy (LLLT), experts will prepare your hair and scalp for the treatment, then administer the laser straight to the scalp.

The laser device is a handheld instrument that can be applied to specific areas of the scalp to achieve the desired results. A little time is spent securing the apparatus in place before the specialist moves it to a new location to ensure that it treats all targeted areas. Treatment with a laser for increased hair growth does not involve invasive procedures, the use of drugs, or surgical incisions.

More About LLLT For Hair:

Low-level laser therapy (LLLT) for hair work is the most important thing you need to realize. It has been demonstrated in several studies to be an effective treatment for hair loss. Both of these studies, one conducted in 2013 and the other in 2014, show encouraging findings for fostering hair renewal. There have been studies conducted more recently, but these are the ones that are referenced the most frequently.

Not a cure-all in a single session: You should also be aware that the therapy for hair growth using a laser is not a once-and-done procedure. You will need to undergo a series of treatments spread out over a few months to achieve the greatest possible outcomes. The precise number of sessions you require is determined by your hair type, age, general health, and whether or not you combine laser hair growth therapy with platelet-rich plasma (PRP).

Those who take medicine that makes them more photosensitive should not use it: Those taking photosensitizing medication are typically not good candidates for low-level light therapy (LLLT) for hair. This drug makes the tissue more reactive to light, which may interfere with how the skin responds to laser treatment.


LLLT has been used for almost half a century to treat a wide range of medical diseases and in several different anatomical locations, but it has shown a very low rate of negative effects in all of these applications. Consult your primary care physician before beginning any treatment if you have any concerns.
