I’m a redhead masquerading as a blonde. A few years back, I was going through a phase of bleaching my hair to within an inch of its life, so hair oil became my must-use product to keep it looking and feeling healthy. And regardless of whether I’m highlighting or balayaging, I’m always super diligent when it comes to using purple shampoos and conditioners to neutralise the brassy tones that creep back into my hair between colour appointments. But back then—no matter how many inky-hued products I threw at my hair, the warm tones kept stubbornly returning at a fierce pace.
It wasn’t until I met with my colourist, Sibi Bolan, creative hair colour consultant at Josh Wood, that she told me my trusted hair oil, the product that was nourishing my tresses, was also the root cause of my unusually quick switch from creamy blonde to straw-like yellow.
You’d think diligently using a hair oil on highlighted blonde hair that goes through so much processing would be the right thing to do, and while using hair oil isn’t necessarily terrible, it’s the type of oil you choose that is wrecking your colour.
“For beautiful bright blonde hair, avoid hair oils that are yellow in colour,” explains Bolan. Yep, those rich-hued hair oils that leave lengths so silky smooth are playing a big part in your fresh blonde ’do turning brassy. (I know, I was shocked when Bolan dropped that bombshell on me, too.) “The lighter your shade of blonde is, the more likely it is to stain and turn it slightly brassy or yellow over time.”
So what should you do? Sure, you could switch to a mask, but there is something so satisfying about how quick and easy a hair oil is to apply. Bolan recommends switching to a clear hair oil instead. “Yellow oils tend to be heavier on fine European hair types, also leaving it a little overloaded,” she adds.
