Acid Color 4/N 60ml – A Comprehensive Overview

The Acid Color 4/N 60ml is a premium semi‑permanent hair colour designed to deliver natural, mid‑brown tones with exceptional coverage and longevity. This product belongs to the renowned Goldwell Colorance line, known for its high‑quality pigments, advanced chemistry, and professional results.

Shade Profile: 4/N – Mid Brown

The 4/N designation indicates a medium brown shade that balances warmth and depth. It is ideal for clients seeking:

• A subtle lift or correction of darker roots.
• Enhancement of natural brown hair with a smooth, blended finish.
• A versatile base for future highlights or lowlights.

Product Format and Volume

This colour is supplied in a 60 ml tube, which typically yields enough product for:

• 1–2 standard applications on average‑sized hair (approximately 150 cm²).
• Multiple touch‑ups or small sections for precise corrections.

Key Ingredients and Chemistry

The formula combines:

• Acidic Pigments – These provide a stable, long‑lasting colour that resists fading even after multiple washes.
• Hydrating Agents – Such as glycerin and panthenol to maintain moisture balance during processing.
• Silicone Derivatives – Offering smoothness, shine, and protection against environmental stressors.
• Low‑pH Buffer System – Ensures optimal penetration of the pigment into the hair shaft while preserving cuticle integrity.

Application Procedure

1. Preparation: Perform a strand test to confirm desired intensity and ensure no allergic reaction. Section hair into manageable parts using clips or ties.
2. Mixing: Shake the tube well before use. If required, mix with the recommended developer (usually 20 vol% peroxide) in a separate bowl until fully blended.
3. Application: Apply the colour from roots to ends using a brush or applicator bottle. For root coverage, start at the scalp and work downwards; for mid‑lengths, apply evenly across sections.
4. Processing Time: Leave in place for 30–45 minutes, depending on desired depth. Monitor colour development every 10 minutes to avoid overprocessing.
5. Rinse & Condition: Rinse thoroughly with lukewarm water until the rinse is clear. Follow with a protein‑rich conditioner to seal cuticles and lock in colour.

Resulting Colour Characteristics

• Natural Mid Brown Tone – A balanced shade that complements various skin tones.
• Soft, Luminous Finish – The silicone component imparts a subtle shine without heaviness.
• Gradual Fade Pattern – As the product is semi‑permanent, it fades evenly over 4–6 washes, allowing for natural regrowth.

Benefits of Using Acid Color 4/N

• Low Damage Profile: The acidic formulation reduces cuticle lift compared to alkaline dyes, preserving hair strength.
• Versatility: Suitable for both new clients and those looking to refresh existing colour.
• Professional Finish: Consistent pigment distribution ensures a uniform look across all sections.
• Ease of Use: The 60 ml tube is convenient for salon workflows, providing enough product for multiple sessions without waste.

Aftercare Recommendations

To maximise longevity and maintain hair health:

• Use sulfate‑free shampoos to prevent rapid colour loss.
• Apply a deep conditioning mask once a week to replenish moisture.
• Avoid excessive heat styling; if necessary, use a heat protectant spray.
• Schedule touch‑ups every 4–6 weeks for optimal coverage.

Compatibility with Other Products

The Acid Color 4/N can be seamlessly integrated into various colour strategies:

• Pairing with Goldwell Colorance Natural Highlights for a layered, dimensional look.
• Using alongside Colorance Mid Brown Lowlights to create depth without drastic contrast.
• Combining with Silk‑Finish Conditioners for added shine and softness.

Safety and Handling

While the product is formulated for professional use, standard safety precautions should be observed:

• Wear gloves during application to avoid skin irritation.
• Ensure proper ventilation in the work area.
• Store the tube at room temperature away from direct sunlight.
