As a beautician, one of the most common questions I get from clients with thick hair is how long to leave Wella T18 toner on for the best results.
Wella T18 toner is popular for those who want to eliminate brassy tones and achieve a cooler, ashier blonde shade. However, the optimal processing time may vary depending on the thickness and porosity of your hair.
This post will explore the recommended processing time for Wella T18 toner on thick hair and the factors affecting the results.
What is Wella T18 toner?
Wella T18 toner neutralizes warm, brassy tones in blonde hair. It is typically used after bleaching or lightening hair to a pale yellow shade, as it works best on hair already at a light blonde level.
The toner contains violet hues that counteract the yellow tones, resulting in a cooler, ashier blonde shade.
How long should I leave Wella T18 toner on thick hair?
The recommended processing time for Wella T18 toner on thick hair is between 15 and 30 minutes. However, the actual processing time may vary depending on the starting level of your hair, the desired result, and the hair’s porosity.
Porosity refers to how easily your hair absorbs and retains moisture, affecting how hair color products are absorbed and processed.
Factors that can affect the processing time of Wella T18 toner on thick hair
Starting level of hair: The starting level of your hair refers to its natural color or level before it is lightened or bleached. If your hair is naturally very dark, it may require a longer processing time with the toner to achieve the desired result.
Desired result: The desired result will also play a role in determining the processing time of the toner. If you want a light, cool-toned blonde, leave the toner on longer.
The porosity of hair: Your hair’s porosity will affect how well the toner is absorbed and how long it takes to process. If your hair is highly porous, it may absorb the toner quickly and require a shorter processing time. If your hair is less porous, it may take longer for the toner to penetrate and process.
Tips for applying Wella T18 toner on thick hair
- Start with clean, dry hair: It is crucial to start with clean, dry hair to ensure the toner is evenly distributed and processed.
- Use a tint brush: A tint brush can help you apply the toner evenly, especially on thick hair. Apply the toner from root to tip and avoid overlapping the product.
- Monitor processing time: Monitor the toner while it processes to avoid over-processing or under-processing. Set a timer for the recommended processing time and check the color periodically.
- Rinse thoroughly: After processing, rinse the toner thoroughly with cool water to remove all the product. Use a gentle shampoo and conditioner to avoid stripping the hair of moisture.

Still, the actual processing time may vary depending on the starting level of your hair, the desired result, and the hair’s porosity.
By following the tips for applying the toner and monitoring the processing time, you can achieve a beautiful, even result on your thick hair. It is also important to note that you may need more than just a toner to achieve your desired shade, and you may need to use additional hair color products or techniques.
