The Easiest Way to Prevent Brassy Hair, According to an Expert

Updated 08/30/18

Raise your hand if you've ever felt personally victimized by brassy hair. Unwanted warm tones can creep into ashy blonde or highlighted brunette hair a few weeks after you get color applied, and, of course, it seemingly happens overnight. You go to bed with hair that looks fresh and wake up the next morning with a yellow cast to your strands. Once brassiness happens, it's difficult to get rid of it. Difficult, but fortunately not impossible.

We talked to Christine Silverman, a colorist at famed L.A. salon Ramirez Tran, to get her tips on how to get rid of brassiness. (Spoiler: The best treatment is prevention.) Say goodbye to yellow- and orange-tinted hair with these tips. 

Get a Shower Filter

"This is the most important thing you can do," Silverman says. "It will remove chlorine and minerals from the water that discolor the hair."

Get Glossed

"Come in for a gloss in between lightening services regularly. This will bring the tone back to where it should be as well as add moisture and shine," Silverman explains.

Go Silicone-Free

"Avoid products with silicones because they coat the hair and cause discoloration." Try Living Proof No-Frizz Nourishing Oil ($38).

Get Some Coconut Oil

"Put coconut oil on your hair before getting in the pool/hot tub/ocean. The chemicals in pools and saltwater of the ocean can wreak havoc on your color. Just give it a barrier before you take the plunge," Silverman explains.

Use Purple Shampoo (Sparingly)

It's pretty much canon at this point that purple shampoo can help get rid of brassiness. But Silverman likes to use it sparingly. "This can remove unwanted brassy tones, but I recommend mixing it with a regular shampoo so it doesn’t dull or leave an ashy cast to the hair. I like Fanola No Yellow for this."
