Low level laser therapy (LLLT) for hair loss is one of the most sought in Europe and USA as an effective treatment for most forms of alopecia. LLLT can be helpful in treating chronic pain, decreasing inflammation, and helping with wound healing for 50 years. Interestingly, some of the initial experiments with LLLT in the 1960's suggested it can lead to increase hair growth. The hair on the backs of the mice were shaved in the area to receive treatment. One group of mice received laser treatments, and one group did not. The hair within the shaven area grew back more quickly in the mice treated with laser.

Currently, LLLT has been proven to be effective in stimulation of the hair follicle which rests at a 5-6mm depth just below the scalp. The laser light stimulates and increases scalp blood circulation-consequently supplying to the area around the hair follicle. As a result of the increased blood flow, more nutrients are delivered to the hair follicle allowing the body to naturally stabilize hair fall and often regrow hair from dormant follicles. However, It does not reactivate dead follicles.

Your hair continues to fall out at the same rate and there is no new growth.

Hair Fall Is Stabilized -

Your hair fall has slowed down considerably or may have even stopped, but no new growth noticed.

Hair Is Restored -

Your hair fall has stopped and your hair is thicker and healthier.

Hair Regrowth -

Not only has your hair stopped falling out, it is now much fuller and new growth has appeared.

Anyone who has alopecia should visit a doctor who specializes in hair restoration and is familiar with what laser therapy can do.
