Low Level Laser Therapy – What You Need to Know
Low level laser therapy uses infra-red laser beams as treatment for an entire range of health conditions such as hair loss. Also known as red light therapy, cold laser and many other names, LLLT is a painless procedure requiring a small time commitment. It simulates hair growth by reducing inflammation and pumping up local blood flow. It is FDA-approved with a promise of safe and effective hair restoration backed by solid scientific evidence.
LLLT and Baldness
LLLT targets a particular type of baldness known as androgenetic alopecia or what is more commonly called female or male-pattern baldness. This is a genetic condition that is found to be the most common reason behind hair loss in both sexes. About 50% of males over 40 and around 75% of females older than 65 have it.
In androgenetic alopecia, a person has a gene that makes him very sensitive to the androgenic hormone known as dihydrotestosterone (DHT), which normally accumulates in the roots of hair follicles. This often leads to hair follicles decreasing in size until they become dormant and keep hair from growing at all.
How LLLT Works on Baldness
Hair growth happens in three parts: anagen, the growth phase; catagen, the transition stage characterized by shrinking hair follicles; and telogen, when hair follicles reach dormancy and shed. LLLT restores hair growth by taking hair follicles back to the anagen phase, that is, by producing a 630 to 670-nanometer wavelength that can penetrate right through hair follicle molecules. This light can stimulate epidermal stem cells that are involved in the regeneration of hair follicles. Because LLLT increases blood flow, it also makes oxygen and nutrients more accessible to hair follicles. Finally, LLLT enhances metabolic processes related to hair growth and helps keep DHT from pooling in the follicles.
Devices and Treatment Time
Experts recommend LLLT twice or thrice a week, whether at a salon or at home, with each session lasting 8-10 minutes. Results are typically noticeable after two or three months of consecutive treatments.
If you’re searching for a solution to hair loss, you will find lots of treatments out there that unfortunately don’t work or aren’t proven to work. Some treatments may actually be effective, except that they tend to have a lot of negative side effects. If you just want something that will make your hair grow back without exposing yourself to a myriad of health risks, consider low level laser therapy.
Of course, what LLLT ultimately does for you will largely depend on where you sought the treatment. A little homework goes a long, long way.
