Description 

A red light therapy cap, a wearable device designed to support scalp health and promote hair growth. These caps use varying wavelengths of light—most commonly red (660nm) and near-infrared (850nm)—to stimulate blood circulation and energize hair follicles at a cellular level.

• Wavelengths: Devices often combine multiple wavelengths. For instance, some use a mix of five different wavelengths (630nm to 940nm) for deep scalp penetration.
• LED Configuration: Caps can contain anywhere from 120 to over 900 LEDs to ensure full-head coverage.
• Functionality: Many models, like the one shown, offer adjustable intensity levels (e.g., five modes ranging from "Soft Light" for daily relaxation to "Powerful Energy Renewal" for deep repair) to suit different scalp needs.
• Convenience: Designed for hands-free use at home, these caps are typically lightweight and often include built-in timers for 10-minute daily sessions.
