Both technologies use the power of light coverage to stimulate cells, increasing blood flow and circulation to the scalp while delivering essential nutrients directly to the hair follicles. The wavelengths play an important role in hair growth and the development of strong, healthy hair follicle cells. Although these light therapy technologies are similar, there are notable differences.
Laser therapy uses a single wavelength to focus a narrow beam of light directly onto the scalp, treating a small area. LED light therapy uses one or more wavelengths to treat larger surface areas of the scalp with a wider band of light. This means that LED light therapy has greater coverage and activates a higher number of hair follicles per cm2 compared to laser hair growth treatments.
