The Best Purple Shampoo for Every Hair Type—and How to Use it

Style

When it comes to artificially enhanced blonde hair, nothing looks (or feels) better than when it’s freshly coloured. A good blonde colour service will leave your hair looking bright, multi-dimension and without a trace of brassiness. But six weeks later…that’s another story. Blonde hair—especially dyed blonde hair—is high maintenance. Not only do you need to be committed to regular touch-ups, but you also need to invest in products to keep your highlights, balayage or dye job looking fresh. Consider these products and treatments your hair colour’s insurance policy. 

If there’s one product every blonde needs, it’s purple shampoo. Why purple? It all comes down to simple colour theory. Purple is opposite of yellow on the colour wheel, which means the pigments cancel each other out. These products deposit a sheer violet tint into the cuticles of your hair’s strands which help neutralize unwanted yellow or brassy tones. And they work just as well on platinum blondes as they do silver foxes. 

How to use purple shampoo

As effective as purple shampoos are at combating brassiness (caused by unavoidable toner fadeout, ultraviolet rays and water with high mineral levels), it’s not a magic wand. One common mistake faux blondes succumb to is overdosing on the purple stuff. “Blondes shouldn’t have to use purple shampoo right after they see their colourists,” says Carolyn Mila, a master colour technician at Toronto Alibi Cutting Room. She explains that as your toner starts to rinse out, which usually takes about six weeks, that’s when the underlying pigment of your hair, which is warm, starts to shine through. “After six weeks, that’s when you should start using purple shampoo,” she says. 

Even though these products are advertised as shampoos and conditioners, they’re not meant for daily use. Mila likens them to a treatment. “Shampoo and conditioner should be [used] for your hair type and texture, not for the colour of your hair.” She warns too much purple shampoo will leave your blonde colour looking dull, flat and grey. “I’ve seen girls that have so much purple shampoo buildup that their hair colour loses contrast with their base, so it looks darker.” The good news is, if that happens it can be easily fixed. Simply lay off the purple shampoo for a few washes and use a clarifying shampoo.

How often should you wash your hair with purple shampoo?

So how often should you use purple shampoo? You can use it as little as once a month or as much as once per week, says David D’Amours, a Kérastase expert and owner of Privé Salon in Montreal. Just don’t use it every time you wash. He suggests experimenting with how long you leave the shampoo on your hair to achieve your desired tone. “If you want to keep your golden tone, just do a quick wash. If you want a more beige-y result, say a sandy blonde, leave it on for three minutes. If you want that ashy tone, go for six minutes,” says D’Amours.

The bottom line is, if you’re looking to remove unwanted warmth from your highlights, balayage or double-processed dye job in-between salon visits, or your naturally grey locks, purple shampoos are your best bet. Here are the top ones for the job.
