Which hair reduction method creates a broad spectrum of light energy to destroy hair bulbs?

Intense pulsed light (IPL) is the correct choice because it utilizes a broad spectrum of light energy to treat hair effectively. This technique emits multiple wavelengths of light, which are absorbed by the pigment in the hair and can penetrate the skin to target the hair bulbs. The energy generated from the light damages the hair follicles, leading to a reduction in hair growth. IPL can be adjusted for different skin tones and hair colors, making it versatile for various clients.

In contrast, the blend method and thermolysis method refer to specific types of electrolysis, which use electrical energy rather than light energy to remove hair. They are effective for permanent hair removal, but they work fundamentally differently from the broad-spectrum approach utilized by IPL. Laser hair reduction, while also effective, uses a specific wavelength of light rather than the broad range that IPL offers, making IPL a distinct and advantageous method in certain contexts.
