What is the therapeutic window?
The therapeutic window in light therapy refers to the optimal dosage range (wavelength, intensity, and duration) that produces biological benefits without causing harm.
Understanding the therapeutic window ensures that light exposure is strong enough to stimulate hair follicle responses without overstimulating or damaging tissues.
Devices designed for hair restoration carefully calibrate light intensity and exposure times to stay within the therapeutic window, maximizing safe and effective results for scalp rejuvenation and hair growth.
