How LLLT Hair Regrowth Works

The research behind Low Level Laser Treatment (LLLT) is a bit of a complex maze to read through, but though all the scientific terms used in research papers and jargon used by industry professionals there are real and palpable results. To keep this information clear and concise for parties interested in LLLT, it would be helpful to speak to the target audience in a more easily understandable manner. 

Whereas a scientific researcher may find it appropriate to state “Laser phototherapy is assumed to stimulate anagen re-entry in telogen hair follicles, prolong duration of anagen phase, increase rates of proliferation in active anagen hair follicles and to prevent premature catagen development” [1], that is overly complicated for the general public when the same effect can be reached by saying “LLLT reactivates growth processes in dormant and slowing hair follicles to prevent the early development of hair regression.” Of course, there is a reason that specifics are communicated between scientists; vague statements are ineffective as they work to prove or disprove results of experiments and get their work done as a community. While that is understandable for them, that does not mean that their published works are the most understandable for consumers weighing their options based upon their findings.

Let’s try this again: Forty-one patients completed the study (22 active, 19 placebo). No adverse events or side effects were reported. Baseline hair counts were 162.7 ± 95.9 (N = 22) in placebo and 142.0 ± 73.0 (N = 22) and active groups respectively (P = 0.426). Post Treatment hair counts were 162.4 ± 62.5 (N = 19) and 228.7 ± 102.8 (N = 22), respectively (P = 0.0161). A 39% percent hair increase was demonstrated (28.4 ± 46.2 placebo, N = 19; 67.2 ± 33.4, active, N = 22) (P = 0.001).” [2]

That text wall could be more easily understood as “41 patients completed the study. No adverse events or side effects were reports. The 22 patients using real LLLT methods saw a 39% hair increase over the 19 patients that were using placebos over the same time period.”


As you learn to read into it, the science behind LLLT becomes considerably clearer; it works, it does not have a history of side effects, and it can help to regrow your hair, unlike hair implants or wigs. The next question must be “Why HairGuru?”  In the quickly developing LLLT market, there aren’t many options in the first place. What HairGuru offers customers that the competition cannot is an affordable price with the same results. Whereas other companies try to validate themselves as an authority in the field with higher price tags and branding, HairGuru just offers cost-effective results to roll out this treatment to all that desire it. There is no compromise to quality as the science behind these products is exact in its administration and function.
