LED Red Light Therapy or Laser to Treat Hair Loss: Which Technology is Best?

• 25 December 2023

Hair loss is an all too common concern affecting more than half the world’s population. With so many modern technological and topical solutions, it can be difficult to find the best treatment for you. We spoke with Certified Trichologist and Registered Nurse, Celestine Gitau about the benefits of LED light therapy versus laser for the best clinical hair regrowth technology from home.


What does hair loss in men and women look like?

Whether caused by genetics, nutritional deficiencies, hormonal imbalances, stress or autoimmune responses, hair loss can be distressing for both men and women. Male hormones, especially dihydrotestosterone (DHT), affect the hair follicles by shortening the hair growth cycle which can lead to premature shedding. It also causes the hair follicles to shrink, pushing them further away from the blood supply and limiting essential nutrients. 



Male pattern baldness is a hereditary condition that comes from a combination of genetic factors and the action of male hormones on the hair follicles. Signs of male pattern baldness include a receding hairline, thinning hair at the top area of the scalp, and bald spots. By age 35, over 50% of men show signs of male-pattern baldness, and this number increases to 85% by age 50.

Female pattern hair loss can occur in women due to similar genetic and hormonal factors. However, they do not typically experience complete baldness thanks to higher estrogen levels that help preserve hair follicles. Instead, they may notice a widening parting or overall thinning on the top area of the scalp. Approximately 40% of women will experience female pattern hair loss by age 50.



How does LED and laser light therapy work for hair regrowth?

Both technologies use the power of light coverage to stimulate cells, resulting in improved blood flow and scalp circulation while encouraging the delivery of essential nutrients directly to hair follicles. The wavelengths play an important role in hair growth and the development of strong, healthy hair follicle cells. Although these light therapy technologies are similar, there are notable distinctions. 

Laser therapy uses a single wavelength to focus a narrow beam of light directly to the scalp, treating a small area. Comparatively, LED light therapy uses one or more wavelengths to treat larger surface areas of the scalp with a broader band of light. This means that LED light therapy has more coverage, activating a higher number of hair follicles per cm² compared to laser hair regrowth treatments. 



What is the best technology for hair regrowth?

LED therapy provides a comfortable, non-invasive treatment free from side effects, offering a safe and convenient solution to address hair loss. LLLT (low-level light therapy) is clinically proven to increase hair density in patients with pattern hair loss over a 16-week timeframe using a wearable, helmet-type device. Now accessible for home use to sustain your 10-minute hands-free sessions, without interrupting your daily routine. The CurrentBody Skin LED Hair Regrowth Device has been shown to increase hair count per cm² by +26.3% after just 16 weeks.

Simple and convenient, the FDA-cleared CurrentBody Skin LED Hair Regrowth Device offers revolutionary red light technology to reverse the effects of slow progressive pattern hair loss. Consisting of 120 red LED light diodes and 2 head circumference options, this wearable technology ensures optimal full scalp coverage. Quick 10-minute daily sessions provide ample nutrients and oxygen to the scalp, leading to thicker hair, increased density and a prolonged growth phase. 


With a clinically proven wavelength (640nm) at 18 j/cm² power, this device is 3 times stronger than the average laser strength. This provides different penetration depths and cellular enhancements, offering the most effective technology for hair loss at home in both men and women.

See the difference that just 16 weeks of 10-minute daily sessions of the CurrentBody Skin LED Hair Regrowth Device can do for your hair regrowth journey.
