Millions of people around the world suffer from hair loss. It can be a very embarrassing and frustrating problem to deal with. Until recently, the only treatment options available were surgery or prescription medications. However, laser therapy for hair loss is now becoming a popular alternative treatment option.
In this article, we will discuss what laser therapy is, how it works, and whether it is an effective treatment for hair loss. Also, we will share before and after results as well as user reviews, so you can decide if it is the right treatment for you.
What is laser therapy for hair loss treatment?
Laser therapy is a form of light-based treatment that utilizes low levels of laser energy to stimulate hair growth.
The most common laser hair loss treatment type is RLT (red light therapy), which typically involves aiming light directly at the scalp. This can help to increase blood flow to the area, which in turn promotes healthier follicles and stronger, thicker hair growth over time. In addition, laser therapy can also help to reduce inflammation in the scalp, which can be a cause of hair loss.
It can be used to treat both male and female pattern baldness, as well as other forms of hair loss, such as alopecia areata. Also, laser therapy does not require invasive procedures and can be done in the comfort of your home, making it a convenient option for those looking to treat hair loss.
Does red light therapy work for hair loss treatment? Based on scientific research
Hair loss can be a difficult and emotionally distressing experience. Fortunately, red light therapy is showing promise for treating hair loss as well as promoting hair growth.
Below are some of the scientific studies that have been conducted to evaluate the efficacy and safety of red light therapy for treating hair loss.
A study  was conducted to determine the safety and effectiveness of red light therapy in men with androgenetic alopecia. A total of 44 patients took part. The active group was irradiated with a 665 nm laser in a helmet-like device. The placebo group was identical but without active lasers. Patients were treated at home every other day for 16 weeks (60 treatments total).
As a result, a 39% increase in hair was demonstrated in the active group compared to the placebo. No side effects or side effects were reported.
The following study  examined treatment with the FDA-approved HairMax laser comb low-intensity laser device in men and women with typical pattern baldness. A total of 128 men and 141 women were randomized to receive either a laser comb (one of three models) or a sham device. The scalp was treated three times a week for 26 weeks. As a result, the average amount of hair after treatment increased by 20 cm2 compared to the baseline. The enlargement in hair density did not depend on the age and gender of the patient.
The next study  was conducted to compare the safety and efficacy of LLLT and minoxidil 5% in the treatment of female pattern hair loss. Ninety patients were randomly divided into 3 groups: LLLT (650 nm) group, minoxidil 5% group, and combined group (LLLT + minoxidil).
As a result, the effectiveness of reducing sebum secretion in the LLLT and the combined group was higher than in the patients who were treated with minoxidil. For improving hair diameter and density, the combined group was better than the rest. No side effects were reported.
Another study  shows the effectiveness of laser therapy in stimulating hair growth. Thirty-five patients, 28 men and 7 women, with androgenetic alopecia, were treated for six months. During treatment, a third of patients reported a slight temporary increase in hair loss during the first one or two months, but this did not happen again after two months.
Ultimately, the amount of hair increased in the temporal area by an average of 55.2% in women and 74.1% in men. In the crown area, the corresponding percentages were 64.9% for women and 120.1% for men. Overall, all patients showed significant improvement.
Before and after results
The non-invasive nature of laser light therapy makes it a great option for hair loss treatment. It has been clinically proven to increase the density of existing follicles, resulting in thicker and fuller-looking hair.
Below we will consider before and after results for patients receiving laser light therapy for hair loss treatment.
Laser light therapy for hair loss treatment reviews
Laser light therapy is becoming increasingly popular as a non-invasive treatment option for hair loss, with many positive reviews from patients and practitioners alike.
Below, we’ll take a closer look at reviews from real patients who have tried this type of treatment.
“I’m 37 and was noticing gradual hair loss since I was 35. I’ve researched countless suggestions that have been posted on Google and have followed my doctor’s recommendations strictly. But my results were not nearly as noticeable. When the hair laser hat arrived and I began wearing it, my hair began changing in appearance. It was formerly well known for my thick, lustrous, long hair.
I’m so happy with this product. My worrying about hair loss was causing me so much distress. Now, this is all behind me. The laser light therapy my hair receives really works wonders.”
— Anna, CA
“I bought the helmet 4 weeks ago and have been wearing it on a daily basis since then. My hair had been thinning due to medicine and stress and I was hoping the laser light therapy would help. After a few weeks of use, I can definitely say that my hair is thicker than it was before. Now, my scalp isn’t as noticeable as it used to be, and my hairline looks much better.”
— Jack, TX
“I’ve observed recently that my hair loss is getting worse. Then I discovered a new product, which utilizes laser hair treatments. After a month of using it, I have seen tremendous improvement in both the thickness and quality of my hair.
The product is easy to use and is not too expensive either. The best part is that I can use it while sitting at home. It has really been a great aid in helping me with my hair loss problem.”
— Rachel, WI
Laser treatment for hair growth side effects
Laser treatment for hair growth is a safe and effective method of stimulating hair regrowth. But as with any medical procedure, there are some side effects and potential risks that should be weighed before deciding to use it.
The most common side effects reported include:
- Swelling of the treated area
Swelling can occur in the treated area as a result of irritation or inflammation caused by the laser. You can use a cold compress to reduce it.
- Redness and mild discomfort in the treated area
The laser may cause some redness and mild discomfort to the scalp, but this should quickly subside after treatment.
- Temporary scalp scabbing
In some cases, temporary scabs may form on the scalp after laser treatment. These should heal within a few days and should not cause any permanent damage.
- Hair shedding
It is normal for some hair to shed after laser treatment. This should only be temporary and new hair should start to grow within a few weeks. So it is important to keep up with your laser treatments.
Some people experience itching in the treated area after laser treatment. This can usually be relieved by using a hypoallergenic shampoo and avoiding scratching the area.
How often to use red light therapy for hair growth
The frequency of red light therapy for hair growth will depend on the product being used, as well as the individual’s specific needs and goals.
It is also essential to allow time between uses for the body to respond and regenerate cells and tissues, so it is recommended to space out sessions at least one day apart. Additionally, it may be necessary to adjust the frequency depending on the intensity and type of product being used and the individual’s response to it.
It is important to follow the instructions provided by the manufacturer or provider. If you are unsure of how often to use a particular product, consult your doctor or dermatologist for more information.
Laser therapy for hair loss is a low-level light therapy used to stimulate hair follicles and promote hair regrowth. It uses a cold or soft laser device, which emits light at a specific wavelength (650-665 nm) and intensity to target the affected area of the scalp. This light energy works by stimulating the cells at a molecular level and helps to increase hair growth as well as reduce thinning of existing hairs.
While laser therapy for hair loss is generally considered safe, it is important to note that some potential risks are involved. These include skin irritation, redness, or burning.
Additionally, laser therapy does not work for everyone, and results can vary from person to person. So, it is important to discuss any concerns with a healthcare professional before beginning treatment.
