Garnier Nutrisse Ultra Color Hair Color

Garnier Nutrisse Ultra Color BL21 Blue Black is a permanent at-home hair color kit that delivers reflective blue-black tones and nourishing care for up to eight weeks of vibrant wear.

This formula is built for transforming naturally dark hair into rich, high-shine shades without sacrificing softness. The kit pairs a permanent colorant and developer with a unique snap-and-pour fruit oil ampoule and an after-color conditioner to help hair absorb pigment while minimizing dryness. It’s a single-box solution intended for short to medium hair lengths; longer or thicker hair may need an extra box for full coverage.

How does the Blue Black shade perform on naturally dark hair?

BL21 Blue Black is formulated to deposit deep, reflective blue-black tones even on dark brown or black bases. The ColorBond technology helps the dye penetrate hair fibers for consistent pigment payoff and long-lasting vibrancy.

• Designed to transform dark bases with ultra-reflective black-blue undertones
• High-impact pigments resist fading for up to eight weeks
• Works without pre-bleaching darker hair in many cases

What makes the fruit oil ampoule important in this kit?

The snap-and-pour ampoule contains five plant-derived oils—avocado, olive, coconut, argan, and shea—that mix into the color blend. These oils help the formula spread smoothly and support hair softness and shine after processing.

• Nourishing oils reduce dryness often associated with permanent dye
• Improves combability and leaves hair feeling silkier post-color
• Easy-to-use single-dose ampoule for consistent results every application

How simple is the application and what do I need to know about timing?

Application is a straightforward three-step mix, apply, and process routine. Combine the colorant, developer, and oil ampoule, apply to dry hair for even coverage, leave for 30 minutes, then rinse and apply the included after-color conditioner.

• Non-drip cream formula spreads evenly for predictable coverage
• 30-minute processing time suitable for most users seeking permanent color
• Includes gloves and clear instructions for at-home use

How long does the color last and how should I maintain it?

The formula is engineered for fade-resistant wear, delivering vibrant color for up to eight weeks with proper care. Using color-safe shampoo and conditioner and washing with cooler water helps prolong tone and shine.

• Color lasts up to eight weeks with fade-resistant pigments
• Pair with Garnier Fructis Color Shield products for extended vibrancy
• Avoid excessive heat styling and frequent washing to maintain intensity

Who is this for: Garnier Nutrisse Ultra Color BL21 Blue Black suits at-home colorists who want a bold, reflective black-blue shade with built-in nourishing treatment. It’s ideal for people with naturally dark hair or darker dyed hair seeking a dramatic, long-wearing change without professional appointments. Choose one box for short to medium lengths; buy two if your hair is thick or longer than 14 inches. This kit is also suitable for vegan and cruelty-free shoppers looking for a plant-oil–infused permanent dye option.
