Garnier Olia Permanent Hair Color Lightest Ash Blonde (9 1/2.1) — Ammonia-Free, Oil-Powered, 100% Gray Coverage

Garnier Olia 9 1/2.1 Lightest Ash Blonde is an ammonia-free, oil-powered permanent hair dye that delivers 100% gray coverage, ash-reflective lightening, and noticeably shinier hair.

This at-home hair color kit uses a 60% oil blend (sunflower and camellia oils) to help carry pigment deep into the hair shaft while avoiding ammonia, silicones, and parabens. Designed to lift and neutralize warm tones for cool, ash-blonde results, the formula aims for vivid, long-lasting color and up to three times the shine versus uncolored, unwashed hair. The box contains everything needed for a single application: developer applicator, colorant tube, after-color conditioner, gloves, and instructions.

How does this oil-powered formula affect color and shine?

The high oil content helps pigments penetrate hair more evenly and supports surface smoothness for a reflective finish. Oils in the mixture also help the hair feel hydrated after coloring, which contributes to a glossier appearance without adding silicones.

• 60% oil blend with sunflower and camellia oils to aid pigment delivery
• Formulated to leave hair silky and up to 3x shinier than uncolored, unwashed hair
• No ammonia to reduce the typical harsh odor and potential scalp sting
• Includes after-color conditioner to restore surface softness post-rinse

Will this shade cover gray and neutralize brassiness?

Yes — Olia 9 1/2.1 Lightest Ash Blonde is formulated for full gray coverage while adding ash reflect to counteract yellow or brassy tones. It’s especially effective on natural hair that ranges from light to dark blonde.

• Promised 100% gray coverage on treated applications
• Ash reflect helps neutralize warm undertones for cooler blonde results
• Works best on natural shades from light blonde to dark blonde for predictable lift
• May require additional boxes for long or very thick hair—see instructions

How do I use the kit safely and get even results at home?

Follow the included step-by-step instruction sheet. The process is straightforward: mix, apply to roots, work through lengths, wait the recommended time, then rinse and condition for best outcome.

• Wear included gloves and perform a patch/strand test as directed
• Mix the developer with the colorant in the applicator bottle and shake well
• Apply to roots first, then spread through mid-lengths and ends for uniform color
• Rinse and apply the enclosed after-color conditioner to seal tone and add softness

How long does the color last and how should I care for treated hair?

This permanent dye is designed for long-lasting results, though longevity depends on hair porosity and hair care habits. Using color-safe cleansing and conditioning products helps maintain tone and shine over time.

• Permanent formula for lasting color; regrowth will require touch-ups
• Recommended to use Garnier Fructis Color Shield Shampoo & Conditioner to protect tone
• Avoid frequent hot-water washes to preserve color and shine
• Use conditioning and UV-protection products to extend vibrancy

Who is this for: Garnier Olia 9 1/2.1 Lightest Ash Blonde is aimed at people who want a cooler, ash-toned light blonde from home without ammonia, those needing complete gray coverage, and anyone who prefers plant-derived oils in their color process. It suits natural hair shades from light to dark blonde and can be used for full color changes or root touch-ups; two to three boxes may be needed for very long or dense hair.
