Garnier Olia Permanent Hair Color — 1.0 Black, Ammonia-Free Oil-Powered Formula, 2 Count for 100% Gray Coverage & Extra Shine

Garnier Olia 1.0 Black is an ammonia-free permanent hair dye that uses a 60% oil blend to deliver rich black color, full gray coverage, and visibly shinier, hydrated hair. Garnier Olia swaps harsh ammonia for natural flower oils (sunflower and camellia) and an oil-delivery system designed to drive color deeper while reducing the drying effects common with traditional permanent dyes. The kit includes developer, colorant, after-color conditioner, gloves, and easy instructions so you can color at home with salon-inspired results and minimal odor.

How does Olia achieve permanent color without ammonia?

Instead of relying on ammonia to open the hair cuticle, Olia uses a 60% oil blend combined with ODS™ delivery technology to help the dye penetrate the hair shaft. The result is a permanent color that lays down pigments while helping the hair surface remain smoother and less stripped.

• 60% natural flower oils (sunflower and camellia) for improved color delivery
• ODS™ technology to propel color molecules into the fiber
• No ammonia, silicones, parabens, or phthalates in the formula
• Delicate floral fragrance with reduced strong dye odor

Will this cover gray hair evenly?

Garnier Olia is formulated for 100% gray coverage on most hair types, providing natural-looking depth and shine. Coverage remains consistent when the product is applied following the included timing and mixing instructions.

• Designed for full gray coverage, including resistant grays
• Use root-first application for regrowth or full-head technique for all-over change
• Processing time and thorough saturation are key for even results

How does Olia affect hair texture and shine?

The oil-rich formula helps leave hair feeling hydrated and softer compared with many permanent dyes. Garnier reports up to three times more shine on treated hair versus uncolored, unwashed hair when used as directed.

• Non-drip velvety cream reduces mess during application
• After-color conditioner included to lock in moisture and smooth cuticles
• Suitable for all textures—fine to coarse—when following product guidance

How easy is it to use Olia at home?

The kit is built for at-home application with a simple mix-and-apply routine and clear instructions. One to two boxes typically cover short to medium hair; long hair usually needs two to three boxes for full coverage.

• Mix colorant into developer applicator and shake to combine
• Apply to dry, unwashed hair; process for the recommended time then rinse
• Finish with the included after-color conditioner for best shine and softness

Who is this for? This Garnier Olia kit is aimed at people who want a permanent color change or reliable gray coverage without ammonia, those who prefer gentler, oil-enriched formulas, and anyone looking to skip a salon visit while still achieving glossy, long-lasting results. It also fits shoppers who prioritize cruelty-free, vegan-certified products and a milder scent profile. Follow the enclosed instructions and perform a patch test if you have a history of hair color sensitivity.
