Why Choose the T100 Hair Growth Cap?

• 336 Triple-Core LEDs: 112 visible red LEDs (660nm) and 224 near-infrared LEDs (850nm) deliver ~40 mW/cm² of consistent irradiance across your entire scalp.
• 360° Full Scalp Coverage: Precisely aimed LEDs reach the forehead, crown, and back of the head for all-around scalp stimulation.
• 3 Customizable Light Modes:
  • Steady Light Mode: Continuous illumination to help strengthen hair roots and encourage thicker-looking strands.
  • Fast Flashing Mode (40Hz): Activates follicle metabolism and boosts scalp circulation to revitalize regenerative potential.
  • Slow Flashing Mode (10Hz): Gently soothes scalp tension and supports a calm, balanced scalp environment.
• Photobiomodulation (PBM) Technology: Uses targeted light energy to stimulate cellular activity, enhance nutrient delivery to follicles via improved blood circulation, and support follicular vitality.
• 20-Minute Auto-Shutdown Timer: Each session ends automatically with 5 audible beeps — no supervision needed. Auto-memory mode resumes your last selected light mode on next use.
• Medical-Grade Liquid Silicone Interior: The patented silicone film encases each LED bead, providing 3D structural support, anti-static protection, and enhanced light convergence for focused energy delivery. Odor-free, aging-resistant, and soft against the skin.
• Generous Universal Fit: Max head circumference of 23.4 inches / 59.44 cm — comfortably fits most head sizes for men and women.
• Flexible Power Options: USB Type-C input (DC 5V/2A). Use at home with a wall adapter, or on the go with a power bank. The 120cm cable (included in the hat-only set) keeps you free from outlet constraints.
• Easy to Clean: Simply wipe the silicone surface with a damp cloth after each session.
• Certified & Safe: CE, RoHS, WEEE, FCC, EMC, and LVD certified.

Frequently Asked Questions

Q: How many LEDs does the Hello Face T100 hair growth cap have, and what wavelengths do they use?

A: The T100 features 336 total LEDs — 112 red LEDs at 660nm and 224 near-infrared LEDs at 850nm. These two wavelengths work together to energize scalp cells at different depths, with an irradiance of approximately 40 mW/cm² in all three light modes.

Q: Can I use the T100 hair growth cap outdoors or while traveling?

A: Yes! The T100 is designed for both indoor and outdoor use. The "With Controller" option is best for travel and outdoor activities due to its compact cable setup and compatibility with a power bank. The "Hat Only" option includes a 120cm cable, making it ideal for home or office sessions where you can connect to a wall adapter.

Q: What is the difference between the 3 light modes on the T100?

A: The T100 offers three modes: Steady Light (constant illumination for strengthening hair roots), Fast Flashing at 40Hz (to activate follicle metabolism and boost scalp circulation), and Slow Flashing at 10Hz (to gently soothe the scalp and support a calm environment). Switch modes with a short 1-second button press during a session.

Q: Does the T100 cap shut off automatically?

A: Yes. Each session runs for 20 minutes and then shuts off automatically, signaling completion with five audible beeps. The auto-memory function also saves your last selected light mode so you don't need to re-select it at your next session.

Q: Is a charger included with the T100 hair growth cap?

A: No, a charger/adapter is not included. You will need a compatible 5V 1A or 5V 2A USB charger. Important: Do not use a 12V or 9V adapter from other Hello Face devices with the T100-W controller, as this can damage the unit.
