L'Oreal Paris Excellence Cool Supreme Permanent Hair Color Ultra Ash Medium Blonde — 100% Gray Coverage & Anti-Brass Protection

L'Oreal Paris Excellence Cool Supreme in Ultra Ash Medium Blonde is a permanent at-home hair color that delivers full gray coverage with anti-brass protection and an ashy, cool-toned finish.

Designed to hide even stubborn grays while maintaining a cool, ash-blonde result, this permanent hair color combines a non-drip crème formula with a triple-protection anti-brass system and a purple conditioner to neutralize unwanted warm tones. The kit targets root-to-tip brightness and long-lasting coolness, offering salon-style color at home with extra care for hair fiber during the process.

How does this shade keep brassiness from appearing?

The Excellence Cool Supreme system uses an anti-brass technology formulated to resist warm, orange-yellow undertones that commonly surface after lightening or coloring. A purple anti-brass conditioner is included to neutralize residual warm tones immediately after the color process, helping maintain the ash effect.

• Triple-protection formula that fights brass during and after coloring
• Purple anti-brass conditioner to tone and refresh cool hues
• Color stability designed to last up to eight weeks against warming

Will this color completely cover gray hair?

Yes — the product is formulated to provide 100% gray coverage, including stubborn or resistant strands. The dye penetrates and deposits consistent pigment across roots and lengths for an even, uniform shade.

• Designed to conceal full gray coverage, even on difficult grays
• Coverage reaches from roots through mid-lengths and ends
• Non-drip crème helps saturate strands for even application

What results should I expect immediately and over the following weeks?

Immediately after application you’ll see a cool, ash-blonde tone with reduced warmth thanks to the purple conditioner. Over the following weeks the anti-brass technology helps retain the ashy character, reducing the need for frequent toning while helping color look fresh and balanced.

• Instant ashy medium blonde results after processing and conditioning
• Continued anti-brass protection helps maintain coolness up to eight weeks
• Formula aims to preserve radiance and resist fading into warm hues

How does the formula care for hair during coloring?

The Excellence kit is built as a care-color system: a creamy, non-drip dye base minimizes mess and evenly coats hair, while the triple-protection approach shields hair fiber at multiple stages. Conditioning included in the kit helps smooth and hydrate hair post-color to leave it softer and more manageable.

• Non-drip crème formulation for even, comfortable application
• Protective ingredients to minimize fiber damage during coloring
• Conditioner restores moisture and adds shine after color processing

Who this is for: This product suits anyone seeking a cool-toned medium blonde with reliable gray coverage — ideal for people who want an ashy finish without salon visits, those managing visible grays, and users who prefer a formula that resists brass and includes post-color care. If you typically experience warm undertones after coloring or want an at-home solution that blends color performance with conditioning, this shade of L'Oreal Paris Excellence Cool Supreme is designed for you.
