Article Banner Article Banner

Whether you’re a natural blonde, platinum blonde, or sun-kissed brunette, unwanted brassy tones can be difficult to maintain and neutralize. Regular shampoos, heat-styling, and environmental factors all contribute to your freshly colored locks or natural strands fading into unpleasant tones.   

That’s where blue and purple shampoos come in and luckily, Eva NYC has options for both! We’ve laid out the basics on our purple and blue shampoo plus their conditioner partners here, so choosing the duo your routine needs is a breeze. We've got you covered with a breakdown of these color-correcting heroes and their matching conditioners, making it easy for you to find the ideal duo for your haircare routine.

Purple vs. Blue Shampoo and Conditioner 

Throwing it back to grade school art class, color theory is a great way to choose which shampoo is best for you. We know colors that are close to each other are friends, while colors that are opposite from each other tend to butt heads (or in this case, cancel each other out). 

Blue sits directly across from orange, and purple sits directly across from yellow, making them partners in crime for a battle against brassiness.   

This means that for BLONDE hair, applying purple shampoo will neutralize the brassy yellow tones, while for BRUNETTE hair, blue shampoo will neutralize the brassy orange tones.
