Ethique - Tone It Down Shampoo Bar (Purple Shampoo)
Say ba-bye to brass and frizz, and hello to bright, bouncy tresses! With no sulfates or petrochemical-derived dyes, this purple solid shampoo (great for blondes and silver foxes) is best used as your regular shampoo to keep the yellow tones at bay. Babassu and jasmine oils add shine and body with beetroot extract for extra colour power – combo with Tone It Down solid conditioner for luminous locks.
Pro tip: to keep brass at bay, use this as your regular shampoo. Find it doesn't lather as much? As it's sulfate free, you don't get huge amounts of foam - so use it twice if you really want that squeaky-clean feeling.
