The Strength Cure system is our premier collection for repairing hair breakage in damaged, color-treated hair. Whether you are dealing with split ends, heat damage, or chemical processing, this system acts like a protein smoothie for your hair, delivering improved strength after just one use. It is designed to fortify strands, smooth the cuticle, and promote healthy growth.

The core Strength Cure line is not, but the collection includes Strength Cure Blonde, which is specifically formulated as a purple shampoo and conditioner system. Strength Cure Blonde combines the repair benefits of the original line with violet pigments to neutralize brassy, yellow tones in blonde and lightened hair. It is the best purple shampoo for those who need both toning and strong repair.

Both systems feature our ANTIFADE COMPLEX® and repairing technology to fix damaged hair. The primary difference is the pigment: the original Strength Cure formulas are designed for all shades of color-treated hair to repair and restore strength. While often referred to as a blue shampoo, Strength Cure Blonde is actually a purple-violet formula designed to banish yellow tones specifically for toning cool blondes and gray hair, while providing the same breakage protection.

Pureology Strength Cure Shampoo is widely considered the best shampoo for damaged hair because it doesn't just wash—it repairs. It is the #1 strengthening shampoo & conditioner in the U.S.*, proven to provide 2x stronger strands** compared to non-conditioning shampoos. It gently cleanses while infusing hair with Astaxanthin and Keravis to help repair damage from the inside out.

Yes. Strength Cure formulas are sulfate-free, including the shampoo for damaged hair and the Dream Healer serum. Our shampoos use a gentle, sulfate-free blend of corn, coconut, and sugar-derived cleansers. The collection is 100% vegan and free from parabens and mineral oils, helping keep hair color vibrant while delivering deep repair.

The system is powered by a potent blend of ingredients, including Astaxanthin (a powerful antioxidant), Keravis (a strengthening plant-based protein), and Ceramide (to repair the cuticle). It also features Arginine, an amino acid that supports stronger-feeling hair, to stimulate the scalp and our patented ANTIFADE COMPLEX® to protect color vibrancy. The fragrance is an aromatherapy blend of raspberry, peach, and water flowers.

Absolutely. While Strength Cure provides deep repair, the formulas are concentrated yet lightweight. If you have very fine hair but need repair, use a small amount of the Pureology shampoo and focus the conditioner on the mid-lengths and ends. For fine, dry hair that doesn't need intense repair, you might also explore the Hydrate Sheer collection.

You will see and feel a difference immediately. The system is clinically proven to deliver improved strength after just one use. For the best results in repairing breakage and preventing split ends, we recommend using the full system: shampoo, conditioner, and the Dream Healer serum or Superfood Mask regularly.
