Purple shampoo is a game-changer for blonde hair, neutralizing unwanted brassy yellow tones and brightening your color. It’s a must-have for maintaining a cool, vibrant blonde hue. The key to its success lies in the purple pigments, which counterbalance the yellow undertones that can appear in blonde hair due to factors like sunlight, hard water, or heat styling tools.

Purple shampoo isn’t just for color-treated blondes. Natural blondes and those with unicorn hair colors can also benefit from its toning properties. To use it effectively, apply it like a hair mask, massaging it into damp hair and leaving it on for 2-5 minutes before rinsing thoroughly. For regular maintenance, use it once a week, but if you want a more intense finish, you can use it every other wash. Always wear gloves to avoid staining your hands.

Remember to check that the water fades from purple/blue to clear when rinsing, as this indicates the shampoo is working correctly. It’s also important to use purple shampoo** alongside your regular shampoo and conditioner.
