The application time varies from person to person; it depends on the individual hair structure. In general, the minimum application time is 2-3 minutes and the following rule applies: The longer the application time, the more intensive the result.
Some shades need longer to develop. Tip: Remove the tinting paste from one eyebrow after 2-3 minutes and check the result and/or show the client. If the tinting result is not intensive enough, please apply the tinting paste again.
