Garnier Olia Permanent Hair Dye - Silver Smoke

Yes, Garnier Olia uses an ammonia-free formula, powered by natural flower oils, which provides a more pleasant scent during the colouring process compared to traditional ammonia-based dyes.

Garnier Olia is a permanent hair dye, meaning the colour is designed to last until your hair grows out or is re-coloured. Actual longevity can vary based on hair porosity, wash frequency, and sun exposure.

Yes, you can typically use permanent dye on previously coloured hair. However, the resulting shade may vary based on your hair's current colour and condition. Always perform a strand test to predict the final colour.

Each box contains 1 x developer cream, 1 x after-colour conditioner, gloves, and a detailed instruction leaflet to guide you through the colouring process.

Apply a small amount of the unmixed dye components to a clean, small area of skin, such as behind your ear or on the inner elbow. Leave it uncovered for 48 hours. If you experience any redness, swelling, or itching, do not use the product.

Garnier Olia Permanent Hair Dye is formulated to provide up to 100% grey coverage, delivering a uniform and vibrant Silver Smoke shade even on resistant greys.

While the ammonia-free formula is generally milder, individual sensitivities vary. Always perform a patch test 48 hours prior to full application, especially if you have a sensitive scalp or known allergies.

Ensure you followed the development time exactly (45 minutes). Incomplete grey coverage can occur if the product was not left on long enough or if application was uneven. Ensure thorough saturation of hair during application.

Immediately rinse hair and scalp thoroughly with water. Discontinue use. If symptoms persist or worsen, consult a medical professional. Always perform a patch test 48 hours before each use.

This often results from uneven application. Ensure hair is fully saturated with the dye mixture, applying in small, even sections. For future applications, consider using a fine-tooth comb to distribute the product evenly after initial application.

While Olia is designed to protect against dryness, some individuals may still experience this. Ensure you use the included after-colour conditioner generously. For ongoing care, incorporate deep conditioning treatments or hair masks into your routine.

Always apply barrier cream (like petroleum jelly) to your hairline, ears, and neck before application. Immediately wipe any dye that gets on your skin or surfaces with a damp cloth. Protect your clothing and work area with old towels.
