Laser therapy or low-level laser therapy (LLLT) is a type of modern hair growth therapy that improves blood supply to the weak cells.
It is also known as red light therapy or cold laser therapy, soft laser biostimulation and photobiomodulation.
Low-level laser therapy illuminates photons into scalp tissues. These photons are consumed by the weak cells to support hair growth.
This improvement of blood supply encourages the hair follicle to grow more hairs.
The best part is this type of therapy is totally safe and will not burn or harm your tissues. The idea is only to bring more blood to your hair follicles and promote hair growth.
There are different types of laser hair growth devices available out there that claim to improve your hair density.
Accelerating the follicles in the scalp tissue to invigorate hair development is generally accepted as a safe method that is less intrusive than hair transplantation.
It’s critical to remember that treatment may not work for everybody. Treatment can create more amazing outcomes in individuals with androgenetic alopecia. Then again, individuals who are especially complete bald are less inclined to profit by laser hair treatment.
Does it really work, or the same marketing gimmick like other market devices?
For this, we will have to find out what the research says about low-level laser therapy (LLLT).
According to some studies, it is a safe, harmless and clinically proven therapy for restoring hair follicles to grow fuller and denser hair.
This type of therapy is most commonly used in male and female pattern baldness and alopecia. It will not work for another type of hair loss like hypotrichosis and other abnormalities.
According to a randomized, double-blind study, a 655nm low-level laser therapy can remarkably improve males’ hair count with androgenic hair loss.
Another study also suggests that this therapy type is safe and effective for both men and women with androgenic alopecia.
Another controlled study mentioned that these devices have an excellent safety profile with very low to no side effects.
Some of the well-known brands on the market are Capillus Cap, iRestore, HairMax Laserband and many others that claim to improve your hair growth.
Is low-level laser therapy FDA approved?
Although the long term effectiveness and safety haven’t yet established, some of the manufacturers of LLLT caps and helmets still claim to be FDA cleared.
These devices are categorized as medical devices by the FDA, so they don’t have the same level of investigation and testing that medicines go through before approval.
Bottom Line
As with any treatment option, there are some pros and cons, so it is important to know all the available information before choosing any therapy.
Although LLLT is more expensive, time-consuming, and may not work for some people; many people still turn to this type of therapy because it is relatively harmless with no side effects. Some studies also support this treatment.
Medication like minoxidil, finasteride and hair transplant surgery can also be used to stop hair loss. Still, It’s always recommended to consult your doctor if you have sudden and rapid hair loss because this might indicate underlying health problems that need to be addressed.
