Summary
Scientists in South Korea have created a wearable hat that uses light therapy to help prevent hair loss. This new hat is made with flexible materials that fit comfortably and provide even light coverage, making it more practical than older, bulky devices.
Key Facts
- Researchers at the Korea Advanced Institute of Science and Technology (KAIST) developed the new phototherapy device.
- The device uses soft, cap-like OLED-based materials instead of bulky helmet-style equipment.
- Tests showed the hat could reduce the aging of hair follicles by about 92%.
- Current hair-loss treatments with drugs can cause side effects, increasing interest in safer options like phototherapy.
- Existing phototherapy devices are often uncomfortable and not evenly effective across the scalp.
- The new device emits uniform light using area-emitting OLEDs in the 730 to 740 nanometer range.
- This specific light wavelength is key to activating cells that help with hair growth.
- The researchers plan to conduct more studies to ensure the device's safety and effectiveness.
