Kerastase Blond Absolu Masque Ultra-Violet hair mask
This purple wrap is ideal for cool-toned blonde hair that is bleached or curly. The wrap penetrates the fiber and removes unwanted warm and yellow tones. It moisturizes and rebuilds the hair strands in depth so that the hair is calmed down, and gets a cool blonde color full of shine. Use the wrap once a week or as needed so that warm/yellow tones are neutralized.
Apply the product to washed and towel-dried hair. Massage into lengths and ends. Leave on for 5 minutes to get a light neutralization or longer (up to 10 minutes) to get a stronger neutralization. Add water, work up a lather, then rinse thoroughly.
