Hey Evelina! 👋
The result can depend on which color you used, and how stubborn it is ❤ Even though Colourless is ammonia and peroxide-free, it opens up the hair's surface (cuticle) to lift out color molecules – which can dry out the hair and make it more fragile if it is already in a sensitive condition.
If you want tips and advice from our hairdressers, I can recommend our hair color test that you can find in the Lyko app under the search function - BeautyScan. They are also available via email: frisoren@lyko.com 📧
Have a great day 🤍
