What is Red Light Therapy for Hair Growth?
Red light therapy uses specific wavelengths of light (usually 630nm–850nm) to stimulate hair follicles, improve blood flow, and extend the growth phase of the hair cycle. By delivering energy directly to scalp cells, RLT helps strengthen roots, reduce shedding, and encourage new hair growth.
Benefits of Using a Red Light Therapy Brush
- Stimulates Hair Follicles: Encourages dormant follicles to enter the growth phase.
- Boosts Circulation: Improves blood flow and oxygen supply to the scalp.
- Reduces Shedding: Minimizes hair fall by strengthening follicles.
- Scalp Health: Relieves dryness, dandruff, and itchiness.
- Convenient: Easy to use at home, non-invasive, and drug-free.
