Do you know how the wavelength of red light affects the growth of our hair?
Red Light (630nm&660nm) - "Master of Surface Repair"
Penetration depth: relatively shallow (about 5-10mm), mainly acting on the scalp epidermis and upper hair follicles.
Main responsibilities:
1) Improving the scalp microenvironment: anti-inflammatory, oil control, especially important for hair loss caused by seborrheic dermatitis, etc.
2) Promote superficial blood circulation.
3) Directly stimulate hair follicle stem cells and keratinocytes to promote activation during the early stages of hair growth.
Near infrared light (810nm&830nm) - "Golden Regeneration Band"
Penetration depth: The deepest (up to 30-50mm or more), it can easily reach the root of the hair follicle - the papilla, which is the core of regulating hair growth.
Main responsibilities:
1) Deep activation of dermal papilla cells: This is the most crucial step in hair growth. Papillary hair cells are the "command center" of hair follicles, and upon receiving light energy, they emit strong "growth signals".
2) Powerful promotion of angiogenesis: providing more abundant blood supply to hair follicles.
3) Regulating the cell cycle: Pushing hair follicles from the resting phase (Telogen) back to the growth phase (Anagen).
Near Infrared Light (850nm) - "Deep Energy Engine"
Penetration depth: Similar to 810nm/830nm, it has excellent penetration.
Main responsibilities:
1) Provide basic energy: As a powerful mitochondrial activator, it provides abundant ATP energy for the repair work of deep tissue cells, including hair follicles, hair papilla, and surrounding blood vessels.
2) Collaborative enhancement: Together with 810nm/830nm, it forms a powerful "near-infrared matrix" to ensure no blind spots in stimulating deep hair follicles and maximize treatment effectiveness.
In summary, why is this combination so effective?
The advantage of this multi band approach lies in its three-dimensional and multi-target treatment:
630nm/660nm is responsible for maintaining the "soil" (scalp environment): anti-inflammatory and oil control.
