Why do you recommend using the red light therapy device at a distance of 4–6 inches? Isn’t skin contact more effective?

The wavelengths of 630nm, 660nm, 810nm, 830nm, and 850nm all have clear effects on hair growth, but their levels and mechanisms of action are slightly different, collectively forming a very comprehensive and effective hair growth phototherapy scheme.
Simply put, this is a powerful combination of "surface repair+deep activation". Here are the specific functions of each wavelength:
