Attention blondes + brunettes: all you need to know about purple and blue shampoo! 

Article Banner Article Banner

Whether you’re a natural blonde, platinum blonde, or sun-kissed brunette, brassy tones can be the bane of color-treated hair’s existence. The maintenance can be a doozy, with regular shampoos, heat-styling, and environmental factors all contributing 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.

So, should you use blue or purple 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 applying purple shampoo will neutralize the brassy yellow tones in BLONDE hair, while blue shampoo will neutralize the brassy orange tones in BRUNETTE hair. 

Calling all blondes!
