Meet RG Cosmetics Collagen Shampoo, 8 oz / 235 ml, a NEW formula designed to rebuild strength and elasticity in every strand. This collagen-infused shampoo nourishes from root to tip, helping damaged hair recover its bounce and resilience with each wash.
What makes this shampoo stand out
- Collagen-infused care: A peptide-rich blend works with the hair shaft to reinforce structure, reducing breakage and restoring pliability so strands feel sturdier and more flexible.
- Gentle, effective cleansing: cleanses without stripping essential moisture, leaving hair soft, smooth, and easier to manage.
- Visible elasticity: Regular use supports hair that stretches without snapping, helping you achieve a healthier, more resilient look and feel.
- Natural-looking shine: Lightweight hydration enhances gloss without weighing hair down, revealing a healthy, vibrant appearance.
- Ideal for stressed or damaged hair: Perfect for strands weakened by heat, coloring, or styling, offering a targeted rebuild while maintaining daily usability.
How to use
Wet hair, apply a generous amount of RG Cosmetics Collagen Shampoo, gently massage into a rich lather, then rinse thoroughly. For best results, follow with a RG Cosmetics conditioner to lock in moisture and continue the rebuild-and-elasticity program with regular use.
Who is it for
Designed for anyone dealing with breakage, dullness, or lack of bounce from styling, chemical treatments, or environmental stress. This collagen-focused formula supports hair resilience and manageability, making it suitable for everyday or routine repair—especially for brittle or stressed hair textures.
Size and status: 8 oz / 235 ml. NEW Rebuild Strength Elasticity. Integrate RG Cosmetics Collagen Shampoo into your hair care routine and experience stronger, more elastic strands from wash to style.
