How Does Laser Technology Treat Hair Loss?


March 20, 2018

Low level laser (light) therapy, or LLLT, was accidentally found to regrow hair by a physician in the 1960s. Since then, LLLT has long been proven to promote tissue repair and cell regeneration—which is very useful for hair regrowth. Laser therapy has been clinically studied and is a safe, effective way for men and women to regrow their hair. 

How Laser Technology Helps Regrow Hair

Cool laser treatments (LLLT) are clinically proven to stimulate cellular activity and increase blood flow to your hair follicles. LLLT works by stimulating tissue molecules that regrow and strengthen your hair through a process called photobiostimulation. It’s similar to photosynthesis in plants. Laser light energy awakens and reenergizes follicles at the root, restoring your hair’s natural growth cycle. 

The hair growth cycle involves four phases: growing (anagen), transitioning (catagen), resting (telogen) and shedding (exogen). Typically, 85-90% of the hair on your head is in the growing phase and will remain there for several years. In the transition phase, your hair growth slows and follicles shrink. As your hair moves into the resting phase, growth completely stops. The shedding phase releases hair from the follicles and occurs at the end of the resting phase. This cycle is why most people shed between 50-100 hairs a day. While the growth phase can last from 2-7 years, the other three phases combined take place within 3-4 months. Hair loss occurs when there is a disruption in the growth cycle. 

The most common cause of hair loss is androgenetic alopecia, better known as male pattern baldness and female hair loss. Men and women with this condition have inherited hair follicles that are sensitive to the hormone dihydrotestosterone (DHT). DHT causes hair follicles to miniaturize over time, producing thinner and finer hair. Eventually, the follicle shuts down completely and can no longer produce hair.

In clinical studies, both men and women with androgenetic alopecia have shown improvements with the use of LLLT, including hair growth, reversal of thinning, increased density and fullness, as well as overall improvement in the quality and condition of their hair. 

Types of Laser Devices

Hair Club offers three FDA-cleared laser devices that are easy to use in the privacy of your home.

The LaserBand
With 82 medical-grade lasers that provide light therapy directly to your scalp, the curved design of the LaserBand includes special teeth that part your hair to optimize light delivery to your follicles. Treatment can take as little as 90 seconds, three times a week. 

The LaserComb
This lightweight, handheld device incorporates 12 medical-grade lasers while patented teeth part your hair to allow the lasers to penetrate your scalp. In just three 8-minute sessions a week, you can rejuvenate your hair follicles to stimulate growth.

The LaserHelmet
The advantage of this device is that it offers full coverage for the top of your head. With just two 20-minute sessions per week, you can stimulate your hair follicles to minimize shedding, promote regrowth and increase thickness.  

The best way to find out if laser hair therapy is right for you is to come in for a complimentary consultation with one of our hair loss experts. You’ll learn about your level of hair loss, the condition of your scalp and what you can do to get your hair back.
