Red Light Therapy
Red Light Therapy (RLT) uses low-wavelength red light to stimulate cellular activity, enhance tissue repair, and reduce inflammation. It’s gaining popularity for its potential benefits in various areas:

For Hair
Benefits:
- Stimulates Hair Growth: Encourages blood flow to hair follicles, promoting hair growth in individuals with androgenetic alopecia (pattern baldness) or thinning hair.
- Reduces Hair Loss: May slow down hair shedding by improving follicular health.
- Thicker Hair: Some studies report increased density and thickness of hair strands.
Cons:
- Results vary among individuals, and significant regrowth is not guaranteed.
- May not work for advanced hair loss where follicles are permanently damaged
Recommended Treatment:
- Sessions: 2–3 times per week for 10–20 minutes per session, depending on goal instructions.
For Skin
Benefits:
- Improves Skin Texture: Boosts collagen production, reducing wrinkles, fine lines, and sagging skin.
