Key ingredients and how they help

• Polyquaternium-6 and conditioning agents support smoothness and detangling during and after coloring.
• Shea butter and macadamia oil provide emollience to help moisturize and protect the cuticle.
• Panthenol (pro‑vitamin B5) and vitamin E (tocopheryl acetate) support moisture retention and shine.
• A balanced blend of emollients and small pigment molecules to help distribute color evenly for a uniform result.

Who should consider this shade

Ideal for anyone wanting a bold, deep red that reads sophisticated and vibrant. Suitable for all genders and hair types, especially those who value color depth without committing to harsh chemicals. If you’re aiming for a vivid red that enhances natural shine while maintaining fiber health, this is a strong choice.

Tips for best results

• Perform a strand test to confirm shade result and track processing time for your hair type.
• Apply evenly from roots to ends to ensure consistent color depth across the head.
• Use gloves during application and follow the package timing for optimal lift and deposit.
• After coloring, use a color-safe shampoo and conditioner to help preserve vibrancy and prevent premature fade.
