How It Works
Include four illustrated cards:
1. Energizes Hair Follicles
- Red light is absorbed by the mitochondria, increasing ATP (cellular energy), which supports healthier follicle activity.
2. Extends the Growth Phase
- Research suggests LLLT encourages follicles to remain in the anagen (growth) phase longer and helps dormant follicles re-enter active growth.
3. Improves Scalp Circulation
- Better circulation delivers more oxygen and nutrients to the hair follicles, creating a healthier environment for hair growth.
4. Reduces Inflammation
- Photobiomodulation may help reduce inflammation around hair follicles, which can contribute to healthier scalp function.
