Garnier Olia Toner - Platinum Blonde

Follow the instructions on the packaging, but typically, development time is between 10-30 minutes, depending on the desired intensity.

Garnier Olia Toner is designed for blonde hair. It's not intended to lighten dark hair; pre-lightening is needed for best results.

You can use the toner as needed to maintain your desired color, typically every 4-6 weeks, or as the brassiness returns.

This toner is designed to neutralize tones in blonde hair and may not provide full gray hair coverage. Consider a color specifically designed for gray coverage.

If the color is too ashy, wash your hair with a clarifying shampoo to remove excess pigment. You can also try toning again with a shorter processing time.

It is recommended to perform a patch test 48 hours before applying the toner to your entire head, especially if you have sensitive skin or allergies.

No, it's generally not recommended to mix hair toners with other products. Always follow the instructions provided on the packaging.

Check the packaging for the expiration date. Unopened products typically last for several years, but the product's effectiveness can decrease over time.

Ensure even application of the toner and check that all strands are covered. If necessary, reapply the toner to any missed areas.

Adjust the development time based on the desired shade and perform a strand test before full application.

Use a deep conditioning treatment after toning to restore moisture and softness.
