2. Understanding LED Light Therapy
What is LED Light Therapy?
LED (Light Emitting Diode) light therapy is a treatment that uses specific wavelengths of light to stimulate biological processes in the body. Different colours of light penetrate the skin at varying depths and can have diverse effects on hair and scalp health. This therapy can be delivered through handheld devices, helmets, or panels specifically designed for scalp treatment.
Mechanism of Action
LED light therapy works by increasing blood circulation to the scalp, enhancing cellular metabolism, and promoting the production of adenosine triphosphate (ATP). ATP is crucial for cellular energy and growth, making it essential for healthy hair follicles. The light penetrates the scalp, activating the hair follicles and encouraging growth. This stimulation can lead to thicker, shinier, and healthier hair.
