About Kiierr
As with other laser therapy devices, the scientific concept for LLLT (low level light therapy) is that light emitted from the laser stimulates the growth of hair and reduces hair loss. This process, called photo-biotherapy, occurs when laser light is absorbed by cells and stimulates their metabolism and protein synthesis.
