What is melanin?
Melanin is the natural pigment responsible for hair, skin, and eye color. It exists in varying types and concentrations depending on genetic and environmental factors.
Melanin in the hair shaft may influence how light energy is absorbed and distributed during red light or laser therapy, potentially affecting treatment outcomes.
Understanding melanin’s role is key when calibrating red light therapy devices, especially since individuals with darker hair or skin may absorb energy differently than those with lighter tones.
