Laser treatment for hair growth, also known as Low-Level Laser Therapy (LLLT), has been gaining popularity as a non-invasive treatment for hair loss. But is it really effective? In this article, you’ll discover the science behind LLLT and explore whether it’s a viable solution for those seeking to regrow their hair.

Laser Treatment For Hair Growth
Laser treatment for hair growth involves using low-level laser therapy (LLLT) devices to stimulate hair growth and improve the overall quality of hair. These devices emit red light at a specific wavelength, which is believed to penetrate the scalp and stimulate hair follicles.
The theory behind LLLT is that the light energy stimulates circulation and metabolic activity in the hair follicles, promoting hair growth. LLLT is believed to increase the production of ATP (adenosine triphosphate) in the hair follicles, the energy source for hair growth.
The Benefits Of Laser Treatment
Laser treatment is a non-invasive, painless procedure that promotes hair growth. The treatment works by stimulating blood flow to the scalp, promoting the growth of new hair follicles. The benefits of laser treatment include the following:
- Increased hair growth
- Improved hair thickness and density
- Reduced hair shedding
- Improved scalp health
How Laser Treatment Works?
A low-level laser stimulates blood flow to the scalp during a laser treatment session. The laser light penetrates the skin and reaches the hair follicles, stimulating the production of adenosine triphosphate (ATP), a molecule essential for cellular energy. This, in turn, promotes the growth of new hair follicles and improves the overall health of the scalp.
LLLT can be administered through various devices, including handheld devices used at home and larger devices used in clinics. Treatment typically involves exposing the scalp to the LLLT for a specified period, ranging from a few minutes to an hour, depending on the device.
Laser treatment sessions typically last between 30 minutes to an hour, depending on the size of the treatment area. The procedure is painless and does not require any downtime. Patients can resume their normal activities immediately after the treatment session.
Who Is A Good Candidate?
Laser treatment is suitable for both men and women experiencing hair loss. It is particularly effective for individuals in the early stages of hair loss or those with androgenetic alopecia (male or female pattern baldness). Laser treatment is not recommended for individuals with extensive hair loss or medical conditions affecting hair growth.
How Effective Is LLLT?
Some evidence suggests that low-level laser therapy (LLLT) may be effective in treating hair loss. However, the results of studies are mixed, and the effectiveness of LLLT may depend on the individual’s specific hair loss condition, the type of device used, and the duration and frequency of treatment.
One study published in the Journal of Clinical and Aesthetic Dermatology in 2014 found that LLLT can improve hair density and thickness in men and women with androgenetic alopecia, a common form of hair loss. The study involved 110 participants treated with an LLLT device for 26 weeks. The researchers found that LLLT significantly increased hair density and thickness compared to the placebo.
Another study published in the Lasers in Surgery and Medicine journal in 2013 found that LLLT effectively promoted hair growth in women with female pattern hair loss. The study involved 40 women treated with an LLLT device for 24 weeks. The researchers found that LLLT significantly increased hair density and thickness compared to the placebo.
However, a systematic review and meta-analysis published in the Journal of the American Academy of Dermatology in 2017 found mixed evidence for LLLT in treating hair loss. The review included 11 randomized controlled trials involving 680 participants. While some studies showed a significant improvement in hair growth with LLLT, others did not.
Overall, while the evidence for LLLT in treating hair loss is promising, further research is needed to determine its efficacy and optimal use.
Home-Use LLLT Devices
Several low-level laser therapy (LLLT) devices are designed for home use to treat hair loss. These devices typically use the same technology as those used in clinics. Still, they might be a bit smaller and less powerful.
Home-use LLLT devices come in different forms, such as helmets, caps, combs, and brushes, and may require daily or every-other-day use for several months to see results. Some devices are available over the counter, while others require a prescription.
Choosing The Best LLLT Device
When choosing a low-level laser therapy (LLLT) device for hair loss, there are several factors to consider. Here are some tips to help you choose the best LLLT device:
- Consult with a healthcare professional: It’s important to talk to a dermatologist or hair loss specialist before starting any hair loss treatment, including LLLT. They can help you determine if LLLT is a good option and recommend specific devices based on your hair loss condition.
- Check the FDA clearance: The U.S. Food and Drug Administration (FDA) has cleared some LLLT devices to treat hair loss. Look for an FDA-cleared device to ensure its safety and effectiveness.
- Consider the type of device: LLLT devices come in different forms, such as helmets, caps, combs, and brushes. Choose a device that is easy to use and fits your lifestyle.
- Check the wavelength: Different wavelengths of light may affect hair growth differently. Look for a device with a wavelength range of 630-670 nanometers, effectively promoting hair growth.
- Look for clinical evidence: Check if the device has been clinically tested and has evidence to support its effectiveness. Look for studies that are published in reputable scientific journals.
- Check the customer reviews: Look for customer reviews and testimonials to see what others have experienced with the device. Keep in mind that individual results may vary.
Considering these factors, you can choose a safe, effective LLLT device that fits your needs. Remember, LLLT should not be used as a standalone treatment for hair loss but in combination with other hair loss treatments such as supplements for optimal results.
In conclusion, laser treatment is a safe and effective option for individuals looking to promote hair growth and improve the overall health of their scalp. However, suppose you are experiencing hair loss. In that case, it is essential to consult with a qualified healthcare provider to determine the underlying cause and the best course of treatment.
