Intense and pastel color tones can be achieved only on naturally light blonde or lightened/bleached hair. If your hair is darker than color tone 7 we recommend soft lightening or soft bleaching to color 8 or higher. Check this color chart to see what is your current color
Lighter base hair color gives vibrant and long lasting result after you use our ColorConditioner Pastel & Intense semi permanent colours. If your base color is darker you can still use ColorConditioner to tone out unwanted tones.
Note - If your hair is already in the same color and you just want to refresh it there is no need to lighten your hair.
