Low-level laser therapy is a technic which uses laser light at low levels or near-infrared light to promote edema reduction and invokes and anti-inflammatory response, increase blood circulation and reduce acute and chronic pains.
It can be used for encouraging hair follicles to grow.
With no harms, it boots blood flow to the hair roots and brings nutrients and energy that hair needs to grow.
Treatment protocols include 30 minutes in general and usually need one or two minutes in each area.
The number of sessions can vary within a range of twice or several times per week.
In general, the laser is noninvasive, painless. There are no side effects. It reduces the intake of analgesics (painkillers) and anti-inflammatory drugs, treats acute and chronic pains, and invigorates circulation and stimulation which encourages hair follicles to grow hair.
