Hair loss is a reality for many men, with 85% experiencing it by age 50, according to the American Hair Loss Association. While some may embrace their new look, others turn to advanced tools to fight hair thinning. One of the most popular and effective options is laser hair growth devices, which use low-level laser therapy (LLLT) to help regrow hair. Here’s a breakdown of the top devices recommended by experts for 2025.
What Causes Hair Loss in Men?
Most men lose their hair due to male pattern baldness, a genetic condition influenced by hormones, particularly testosterone and dihydrotestosterone (DHT). This results in a receding hairline and thinning at the crown of the head. Laser therapy devices are particularly effective for treating this condition, according to Dr. Muneeb Shah, a dermatologist, and Dr. Alan Bauman, a hair restoration specialist. Other factors, such as stress or medical conditions, may not respond as well to laser treatments, as these often involve damaged or inactive hair follicles.
How Do Laser Hair Growth Devices Work?
Laser hair growth devices use low-level laser therapy (LLLT) to stimulate dormant or weakened hair follicles. The therapy works by improving blood circulation, reducing inflammation, and stimulating the follicles to re-enter the growth phase. Dr. Bauman explains that this process, called photobiomodulation, involves using light in the red and near-infrared spectrum to enhance cellular metabolism and energy production in the scalp.
Although most devices focus on laser diodes, some combine LED lights for added effectiveness or to reduce intensity. Laser therapy essentially creates an ideal environment for hair follicles to grow by restoring energy to sluggish follicles.
What to Look for in a Laser Hair Growth Device
1. Light Type: LED vs. Laser Diodes
There are two main types of light used in laser hair growth devices: LED (Light Emitting Diodes) and laser diodes. Dr. Bauman recommends laser diodes because they penetrate deeper into the scalp and are more effective at targeting the hair follicle root. However, they also carry a higher risk of side effects like burns, redness, or swelling. LED devices are gentler and better for sensitive scalps, but they may not work as well for severe hair loss.
2. Wavelength
The wavelength of the light is crucial for effective hair regrowth. Dr. Shah advises choosing devices that use wavelengths between 630 and 680 nanometers, which effectively stimulate hair follicle growth. For optimal results, Dr. Bauman suggests a wavelength of 650 nanometers, as it’s absorbed by mitochondria to boost cellular energy and support hair growth.
3. Treatment Length
Laser hair growth devices are not quick fixes. Dr. Shah notes that it takes at least six months of consistent use before you’ll see any noticeable results. Treatment sessions vary in length, with some devices requiring only five minutes of use, while others may take up to 30 minutes. Regardless, regular use is key to success, as skipping sessions can reduce effectiveness.
FDA Approval and Clearance
When purchasing a laser hair growth device, it’s important to ensure it has been cleared by the FDA. FDA clearance means the device has undergone testing to ensure its safety and effectiveness. Dr. Shah and Dr. Bauman recommend only purchasing devices that have received FDA clearance for the most reliable results. While no laser or LED hair growth device has been FDA-approved yet, FDA-cleared options are still the safest choice.
