Targets Breakage Caused by Daily Stressors
Genesis Conditioner is formulated to address the root causes of breakage—heat styling, brushing, and mechanical stress. Edelweiss Native Cells and Ginger Root work to fortify fibers, improving resilience and reducing hair fall when used regularly.

This balm-like yet light conditioner intensely moisturizes without weighing hair down, delivering visible body and salon-worthy shine. Silicone- and sulfate-free, it smooths and detangles for easier styling and fewer split ends.

For optimal protection against breakage, use the conditioner with Genesis Strengthening Shampoo and Serum. Follow the suggested 5-minute leave-in or the in-shower hydration technique to maximize strength, softness, and manageability.
Strengthen Hair, Prevent Future Breakage
Clinically proven results and a professional-grade formula make Genesis Strengthening Conditioner an essential step for anyone combating breakage, dryness, or thinning. Add it to your routine to detangle, hydrate, and build stronger, fuller-looking hair.
