Lasers have a converged light beam which focuses the light energy on a much smaller area
compared to LEDs, which have a diverged light beam that spreads out the light energy making it
much less effective for preventing hair loss and regrowing hair. The light energy coming from a
laser is coherent meaning all the photons are in step with no abrupt changes within in the beam.
LED
= Light Emitting Diode Laser (Converged and Coherent) vs. LED (Diverged and Non
Coherent)
LEDs make non-coherent/incoherent light so the photons are not in step and have abrupt
changes within their beam.
Why do some companies use Lasers and other use LEDs?
Lasers are considered more expensive and much more effective for hair growth. LEDs are
cheaper to make compared to Lasers. LEDs help cut costs and also helps companies increase
the number of LEDs they have in their devices for marketing only purposes. LEDs tests haven’t
been shown to be effective in preventing hair loss or regrowing new hair.
Will ReGrow promote a reduction in hair loss?
Yes, it will. ReGrow treats genetic hair loss and allows users to have long-term success without
experiencing adverse side effects or increased in health risks. Low-level light therapy (LLLT)
uses a scientific process to fight hair loss and promote hair growth by stimulating cell
metabolism at the follicular level. Many formulas on the market use drugs and chemicals to
regrow hair but ReGrow only uses your bodies natural functions to thicken and regrow hair.
Can I prevent hair loss with LLLT?
Preventing hair loss is much easier than awakening and/or regrowing dormant hairs. Reversing
hair follicle miniaturization and extending the hair growth cycle phase are key. The earlier you
catch hair loss and begin LLLT treatment the better.
I have heard LLLT can stop/reduce hair greying and reverse hair greying. Is this true?
There have been some testimonials posted online where users, who have used various LLLT
treatments, state they have noticed a reduction of grey hairs but we do not have any hard
scientific data to back this up. Our assumption with ReGrow is that if you were to experience a
reduction in greying by using LLLT you would have the best chance with ReGrow as we have
the most non-flashing lasers of any product in the industry.
Are there any clinical trials or medical studies that show lasers have stopped hair loss
and regrown new hair?
Many studies have been completed and below are links to a few:
