Garnier Olia Ammonia-Free Permanent Hair Color — 6.65 Intense Red, Oil-Powered 2-Count for 100% Gray Coverage & Extra Shine

Garnier Olia 6.65 Intense Red is an ammonia-free, oil-powered permanent hair dye that delivers vivid red color, 100% gray coverage, and visibly shinier, softer hair.

Made with a 60% natural flower oil blend (including sunflower and camellia oils), this vegan and cruelty-free kit replaces ammonia with oils to push pigments deep into the hair shaft while reducing harsh odor. The boxed set includes a developer applicator, colorant tube, after-color conditioner, gloves, and instructions—everything needed for at-home application. Olia’s formula aims to combine salon-grade permanence with a gentler, hydrating approach so you can refresh or transform your color in one session.

How does Olia create intense red color without ammonia?

Olia swaps traditional ammonia for a high proportion of oils that act as carriers for the color molecules. These oils help open the hair cuticle just enough for pigment penetration while keeping the fiber moisturized, so color appears rich and vibrant.

• 60% oil blend (sunflower and camellia) transports pigments into hair fibers
• No ammonia to reduce strong chemical smell during application
• ODS (Oil Delivery System) designed to preserve hair strength and shine

Will this shade cover gray and last through everyday washing?

Garnier Olia promises full gray coverage and long-lasting color when applied according to the instructions. Expect vivid results that maintain reflect and shine; longevity depends on hair porosity, aftercare, and frequency of washing.

• Formulated for up to 100% gray coverage when used as directed
• Results can hold for several weeks; use color-protecting shampoo and conditioner to extend vibrancy
• After-color conditioner included to seal the cuticle and enhance shine

How do I use the kit for best results at home?

Application is straightforward: mix the colorant tube into the developer bottle, shake, then apply to dry, unwashed hair. Process time and technique vary for full-head color versus root touch-ups—follow the included guide for timing and safety steps.

• Mix and shake the developer applicator with the colorant tube thoroughly
• Apply to unwashed, dry hair; process for the recommended time on the instruction sheet
• Rinse until water runs clear, then apply the included after-color conditioner

What aftercare keeps Intense Red looking fresh and shiny?

Use sulfate-free, color-protecting shampoos and conditioners and limit excessive heat styling to preserve shade intensity. Cool rinse and weekly deep-conditioning treatments help maintain shine and minimize fading.

• Pair with Garnier Fructis Color Shield Shampoo and Conditioner for longer vibrancy
• Avoid daily hot tools and high-heat settings to reduce color fading
• Use the included conditioner immediately after dyeing to lock in moisture and gloss
