Garnier Olia permanent hair color — 7.0 Dark Blonde, ammonia-free oil-powered formula, 2-count kit for 100% gray coverage

Olia swaps traditional ammonia formulas for a 60% natural flower oil blend that helps the color penetrate hair strands while reducing harsh odor. The kit contains a developer applicator, colorant tube, after-color conditioner, gloves, and instructions so you can color at home. This product is vegan and cruelty-free and is formulated without silicones or parabens for those who prefer gentler ingredients without sacrificing rich, salon-style results.

How does Olia’s oil-powered technology affect my hair’s look and feel?

Instead of relying on ammonia, Olia uses natural oils (like sunflower and camellia) to carry pigments into the hair fiber. That oil-forward approach helps maintain moisture and produces more noticeable shine compared with untreated hair.

• 60% oil blend to help color penetrate evenly
• Visibly up to 3x shinier than uncolored hair
• Hydrated, silky finish after coloring and conditioning

Will this shade cover gray hair and how long does it last?

Garnier Olia is formulated for full gray coverage, delivering natural-looking color and reflective tones. Coverage is reliable for weeks when you follow the package directions and use color-safe maintenance products.

• Designed to provide 100% gray coverage
• Color wears naturally with gradual fading, not patchy loss
• Use with color-protecting shampoo and conditioner for longer vibrancy

How easy is it to use at home, and what’s included in the kit?

The kit is ready-to-use with step-by-step instructions. Mix the colorant into the developer bottle, apply to dry unwashed hair, wait the recommended processing time, rinse until water runs clear, then apply the after-color conditioner to seal the shade.

• Developer applicator bottle for even application
• Colorant tube and after-color conditioner included
• Gloves and instruction sheet for safe, guided application

Is Olia gentle, and what should I expect about ingredients?

Olia avoids ammonia, silicones, and parabens and uses naturally derived flower oils to reduce harshness while still delivering permanent color. It is vegan and cruelty-free, making it a fit for shoppers who prioritize cleaner beauty choices.

• No ammonia—reduced strong scent during processing
• Free from silicones and parabens for a gentler formula
• Vegan ingredients and cruelty-free testing policy

Who this is for: Garnier Olia 7.0 Dark Blonde is ideal for people who want a reliable at-home permanent hair color without ammonia, those seeking full gray coverage with a glossy finish, and anyone who prefers vegan and cruelty-free beauty options. It fits short-to-long hair needs (one to two boxes for short-medium hair; two to three boxes for long hair) and works well for touch-ups, event-ready color, or a regular color-refresh routine when paired with color-protecting hair care.
