Low Level Laser Therapy (LLLT) has become one of the most popular treatments for female hair loss, and with the increase in popularity we have also seen an increase in at home options. However, many patients tell us it can be confusing when they try to research and compare all of the LLLT devices. Before we get into the devices, it is important to understand what exactly is LLLT.
LLLT stimulates the hair follicle cells to grow in the scalp and increases cellular activity around the follicle. This also decreases inflammation so existing hairs can grow thicker and stronger. While LLLT has been proven to be effective for many years, the 2014 double-blind study published in the American Journal of Clinical Dermatology, truly showed the power of LLLT in treating hair loss.
With a simple internet search, you will find a number of at home LLLT devices, such as the LCPro by LaserCap, the Capillus, the LaserBand 82 by HairMax, the Theradome, or the iGrow, and this can be very overwhelming to the patient. However, there are a few key differences that you need to look out for when comparing devices.
First, the laser wavelength should be between 650nm-655nm. Secondly, the laser output per diode should be 5mw. Thirdly, the diodes should be true lasers and not just red lights. Lastly, the number of diodes is extremely important. Many of the full caps are sold with varying numbers of diodes, often varying between 80 and 272, but you truly need at least 220 diodes in the cap to ensure you are receiving the proper coverage to the entire scalp. While some products like the HairMax LaserBand 82 only have 82 diodes, since they only cover a third of the head, they have the sufficient number of diodes in the treatment area, you just have to move the device to treat the entire scalp.
If you think you are interested in LLLT, it is important to speak with a hair loss specialist that can not only determine if a LLLT device is right for you, but guide you through the decision making process to purchase the best device.
