There is no doubt that lasers have become a mainstay in dermatology and play a significant role in the field to treat a plethora of skin conditions and improve the look of aging skin. Basically, you don’t have to be a 13-year-old Star Wars enthusiast to geek out over the fact that lasers could be the future of many new skin-care advancements.
However, many banking on low-level laser therapy (LLLT) to stop hair loss might need to continue to hold out hope for new advancements. At this years American Academy of Dermatology’s annual meeting, Boston dermatologist Molly Wanner, MD cautioned that more scientific data is needed before these new treatments can be recommended to the general public.
While several new devices (in-office procedures and at-home devices) are touted to reverse hair loss and restore hair growth, Dr. Wanner says very few of the available devices have been studied in peer-reviewed journals or tested properly to ensure their effectiveness.
One study revealed that a device for reversing hair loss showed an average increase in hair growth of 19.8 hairs per centimeters squared. However, nearly 20 hours of treatment were needed to produce these results—making this a tedious and time-intensive procedure. Not to mention, in evaluation of the results, the hair growth was not considered “noticeable” by the researchers, she explains. “It is very important for consumers to understand that there is currently very limited evidence for all of these new laser and light therapies for hair loss. It is possible that they could pursue a treatment and see no improvement.”
But, don’t give up hope on laser therapy just yet, while dermatologists recommend you err on the side of caution, lasers still could lead to even better treatment options in the future.
