What's Included:

The Science of Strength:

Strength Cure uses an advanced dual-action approach to hair repair. Keravis, a plant-based protein complex, penetrates deep into the hair shaft to strengthen from within and rebuild the internal structure. Astaxanthin, one of nature's most powerful antioxidants (6000x stronger than Vitamin C), heals existing damage and protects against future breakage from environmental stressors. Together, they work synergistically to rebuild hair's strength while Pureology's patented AntiFade Complex® locks in color vibrancy and prevents fade.

How to Use:

Shampoo: Apply a dime-sized amount to wet hair at the scalp. Emulsify into a rich, luxurious lather and work down to ends. Rinse thoroughly. For extra cleansing and nourishment, repeat if desired.

Conditioner: Apply a 5-cent-sized amount to freshly shampooed hair, focusing on mid-lengths and ends where breakage is most severe. Gently massage through to allow deep penetration. Wait 1-2 minutes for normal conditioning, or 3-5 minutes for extra-damaged hair, then rinse thoroughly.

Key Ingredients:

• Keravis Plant Protein – Fortifies and strengthens hair from within
• Astaxanthin – Powerful antioxidant that repairs damage and protects hair
• AntiFade Complex® – Patented technology that maximizes color retention
• Raspberry & Peach Extracts – Provide aromatherapy benefits and natural conditioning
