Thinning Hair Treatment – How does laser light stimulate hair growth?

Truth is, the exact mechanism is not known. There are several different theories about why lasers work as a thinning hair treatment. Here’s what’s been suggested.

Theory One – Laser light is effective as a thinning hair treatment by transferring energy into the hair follicle

This theory says that the laser energy is simply absorbed by the hair follicle, and this stimulates the hair growth. Basically it says you’re absorbing light energy into the scalp, thus causing the hair to grow.

It’s thought to be similar to a plant growing by absorbing sunlight.

Theory Two – laser light flushes out the chemical that makes you bald

The chemical in the bloodstream that makes you bald is called dihydrotestosterone (or DHT). This builds up in the hair follicles and causes baldness. (This is known – it’s not a theory)

One theory of why lasers work so well is that they may be stimulating blood flow around the hair follicle, flushing out the DHT, thus letting the hair regrow.

While this may be part of the reason, it is not a complete answer. Lasers actually stimulate the hair to grow faster, even when just shaved. Shaving has nothing to do with DHT – and lasers still work.

In fact, the effect that lasers have on hair growth was discovered completely by accident.

It was in 1967, shortly after the first lasers were invented, that Endre Mester in Semmelweis University was doing experiments with lasers on skin cancer. He noticed that when applying lasers to the backs of shaven mice, the shaved hair grew back faster in those mice in the treated group versus the untreated group.

Since then, numerous experiments have shown that a certain exact wavelength of laser light – 650 nm (nanometers) – is most effective as a thinning hair treatment. This is the laser we use in all Super Grow Laser products.

This simple observation sparked an entire industry, and gave people with thinning hair the first chance at a real solution. The laser light regrows a person’s own natural hair, right where it belongs. No dangerous drugs or surgery.

However it works, we just know one thing for sure – IT DOES WORK AS A THINNING HAIR TREATMENT.
