L'Oréal Casting Crème Gloss No.550 Mahogany is an ammonia-free semi-permanent hair color that delivers rich, glossy, long-lasting color with extraordinary shine. The creamy formula blends seamlessly with natural hair, providing 100% grey coverage and fade-resistant results that last up to 28 shampoos. Enriched with conditioning agents, it leaves hair soft, smooth, and brilliantly colored.

Why Choose It?

• Ammonia-free means no harsh chemical smell and less damage to the hair structure, while still delivering salon-quality, vivid No.550 Mahogany color. The gloss technology adds a mirror-like finish that makes every strand reflect light beautifully — something permanent dyes struggle to achieve.

When to Use It?

• Apply to dry, unwashed hair. For best results, start at roots and work through to ends. Leave on 20–30 minutes depending on intensity desired. Re-apply every 4–6 weeks or when roots need refreshing.

Key Ingredients

• Ammonia-Free Color Cream: gentler permanent coloring system with lower pH for reduced scalp irritation
• 2% Hydrogen Peroxide Developer: lower-strength oxidiser for minimal hair damage
• Pro-Keratin Conditioner (post-color): repairs and seals the cuticle after color
• Colorants (specific permanent dyes): form large color molecules within the cortex that cannot be washed out

How to Use?

1. 1. Mix color with the developer cream (included). 2. Apply to dry hair starting at roots, then work through lengths and ends. 3. Leave for 20–30 minutes. 4. Rinse thoroughly until water runs clear. 5. Apply the conditioner sachet included and leave for 2 minutes, then rinse.

Warnings & Precautions

• Do not use if you have had an allergic reaction to hair dyes. Always perform a sensitivity test 48 hours before use. Avoid contact with eyes — if contact occurs rinse immediately with water. Contains colorant — protect clothing and surfaces. Keep out of reach of children.
