8 Expert-Picked Purple Shampoos That Will Keep Your Blonde Hair Blonde

“This cancels out the perfect amount of brassiness, without leaving the blonde looking flat and dull,” explains Pearl. It’s also very hydrating so it keeps your dyed (and maybe slightly parched) hair nourished. 

The OG purple shampoo most colorists keep in their personal kits. Lee also notes that you don’t have to be a professional to use the product and can easily work the shampoo into your home routine once a week. “Also for the cost conscious it’s the most bang for your buck,” she adds.

“It maintains the clarity and tone of platinum and cool blonde hair and protects against the yellowing effects of sun exposure,” explains Lee. It’s also made from natural ingredients so you don’t have to worry about harsh chemicals ruining your blonde. 

A purple shampoo for a professional. It’s very powerful so Lee recommends using with an expert or very carefully applying and/or diluting the product. “This works really well for clients who want absolutely no warmth, and those who have a deliberate silver tone to their natural or artificial color,” says Lee. But make sure to proceed with caution. If the hair is too porous when the product is applied, it will turn a grayish purple tone. 

“I like to use the new Moroccanoil Blonde Perfecting Purple Shampoo every four washes to keep my ends bright,” explains Scarlett. “I recommend my blonde and blonde-highlighted clients do the same.”

“SignatureBlonde is perfect for blonde, bleached, and silver color-treated hair, but also works great on brunettes, highlighted hair and other shades that are experiencing discoloration,” says Markham. “The super gentle formula is sulfate-free and salt-free so it never strips color. Plus, it includes our Advanced ColorLast System, which delivers full-spectrum UVA/UVB color and heat protection.” 

“I love grown-in roots and only bleach my hair two or three times a year, but I’m fanatical about deep conditioning,” says Kosin. “This mask takes me one step closer to that elusive silvery-blonde while providing a healthy conditioning treatment.” 

“I’m a big fan of Amika’s styling products, and now I’ve added their purple shampoo and conditioner to my weekly rotation,” adds Kosin. “The resulting silvery strands are exactly the color I’m looking for.”
