Low Level Laser Hair Therapy preserves and stimulates hair follicles through a process called phototherapy, where specific wavelengths of light from laser diodes increase blood flow and cellular energy production to the hair. This pain-free process helps make hair cells function better, improving hair quality and strength. Whether used in combination with other nonsurgical treatments or hair transplant procedures, LLLT has the potential to significantly slow down hair loss and promote hair growth by improving the health of hair follicles.
