A professional hair laser can often help to stimulate hair growth.
Laser treatments are about raising the energy level in cells and work in much the same way as the photosynthesis process in nature. Sunlight contains all types of light, but it is the energy from red light that plants convert, together with carbon dioxide and water, into carbohydrates (building blocks) and oxygen.
In the body, it works in the same way and a laser treatment also uses the red light, 650nm. Mitochondria are a component of cells and are often referred to as the powerhouse of the cell. They play a major role in metabolism and it is in the mitochondria that nutrients and oxygen are converted into energy. These tiny components also control how cells divide.
The light activates the mitochondria and triggers cell division. More cells means more building blocks for each hair, which build up, become stronger and have the energy to grow longer.
