Moroccanoil Blonde Perfecting Purple is a shampoo specifically designed for individuals with blonde or gray hair. It is a purple-colored shampoo and conditioner that helps to neutralize brassy and yellow tones in the hair, leaving it looking brighter and more vibrant. The purple hue counteracts the warm tones that can develop in blonde or gray hair over time, such as brassiness or yellowing caused by factors like sunlight, environmental pollutants, or product buildup. By using this purple shampoo regularly, you can maintain a cooler, more neutral blonde or gray shade. In addition to its toning properties, Moroccanoil Blonde Perfecting Purple Shampoo also contains nourishing ingredients to help improve the overall condition of your hair. It is enriched with argan oil, which is known for its moisturizing and smoothing effects. This helps to hydrate and detangle the hair, leaving it soft, shiny, and manageable. To use the shampoo, you would typically apply it to wet hair, massage it in, and leave it on for a few minutes to allow the purple pigments to work their magic. Then, rinse thoroughly and follow with a conditioner if desired. It's important to note that since purple shampoo is highly pigmented, it's recommended to use it once or twice a week to avoid over-toning your hair. Follow up with conditioner on damp hair. Apply conditioner from roots to ends. Leave on for 3 minutes and rinse. Ingredients include argan kernel oil, citric acid, coconut acid, violet no 2, and glycerin. This is a unisex product, comes in liquids form, 6.7.
