Ingredients and how they matter

• Aqua (Water) — the base for the dye, enabling even distribution through hair fibers
• Hydrogen Peroxide — opens the hair cuticle to allow color penetration and lift
• Cetearyl Alcohol — provides emollience and helps thickened formulas spread evenly without dripping
• Sodium Salicylate — helps balance formulation texture and stability
• Trideceth-2 Carboxamide MEA — assists with blendability of the color mixture
• Phosphoric Acid — adjusts pH for optimal dye performance
• Ceteareth-25 — conditions hair during processing
• Tetrasodium EDTA / Tetrasodium Pyrophosphate — stabilizers that help preserve formula integrity
• Glycerin — humectant that supports moisture during application

Who this is for and how to use it

Designed for adults seeking rich, long-lasting color with good grey coverage, this shade delivers a cool light brown result with depth and shine. The oil-in-gel texture helps the color adhere to the hair without drips, and the Shine Protect Conditioner helps maintain softness after coloring.

Important safety notes: test for allergy 48 hours before colouring. If any irritation occurs, discontinue use and rinse out immediately. Keep out of reach of children. Follow the included product instructions for allergy testing timing and processing times such as the 25 minute base time for non-grey areas and an additional 15 to 20 minutes for grey coverage, as applicable.

Result expectation: a luminous, long-lasting color that won’t fade or wash out quickly, with up to 9 weeks of wear depending on hair condition and washing frequency. This product is a versatile choice for those who want consistent, salon-like results at home.

In practice, you’ll apply the color to dry, unwashed hair, process according to grey coverage needs, rinse, and finish with the Shine Protect Conditioner for optimal shine and softness.

With 1 Piece packaging, the process is streamlined and making it a reliable option for at-home color refreshes and gradual shade adjustments.

The shade 6C Cool Light Brown offers a balanced cool undertone that complements a variety of skin tones and styles, helping you achieve a natural, multi-dimensional look that remains vibrant between touch-ups.

Closing note: store in a cool, dry place and avoid heat exposure. If you have sensitive skin or a history of chemical reactions with hair dyes, perform the allergy test as directed and consider a strand test before full application.
