Update: September 2019 — Revian Red September 2019 Press Release.
Quote from Dr. Rodney Sinclair:
“It took almost 20 years to work out the ideal wavelengths of light, the best fluence or ‘power’, how long the treatments should last and how often the treatments need to be repeated.”
It has been a long time since I wrote a post on low level laser therapy (LLLT) to treat hair loss. Although a very controversial subject, there are a number of studies that suggest LLLT can benefit hair growth.
Almost always, laser therapy will not bring back hair in totally bald areas of the scalp. However, LLLT can make existing hair thicker according to many findings. The latest study in support of low level laser therapy for hair growth was published in Lasers in Medical Science in August 2019.
Note that the Revian Red system is currently on sale on Amazon after coupon application. Regular price is $795 on their website. Average reviews for Revian Red cap so far are 4/5.
In April 2019, a new laser system for hair growth called Revian Red entered the market. See the press release from its manufacturer, PhotonMD (North Carolina). Revian Red is FDA cleared for the treatment of androgenetic alopecia in both men and women. Note the difference between FDA approved and FDA cleared.
One of the more interesting aspects about Revian Red is that it is a wireless cap that comes with a phone app that you can use to take photos and track results. The app also reminds you of the 10 minutes per day treatment schedule.
Also of interest, Revian Red is based on Red LED Light Therapy. See my past post on laser therapy for hair loss and wavelength. The company terms is as modulated light therapy. Red light wavelength ranges from 400 nm to 700 nm.
Revian Red underwent clinical trials in Australia that were led my the famous dermatologist Rodney Sinclair. According to Revian’s own site, clinical trial results seem to have been favorable. However, the results are not as yet officially published, even though the trials were completed in May 2019.
Before Revian: Other Laser Devices
I have covered a number of other low level laser therapy devices on this blog in the past. These include combs, helmets and caps.
The oldest of these FDA cleared lasers is the HairMax LaserComb, while the more recent of these is the Theradome Laser Helmet. Also cleared are the funky looking iGrow Laser Helmet; the iRestore Hair Growth System; and the Capillus Laser Therapy Cap.
