If you've ever tried to lighten your hair at home — or caught sight of your reflection halfway through a double-process treatment — you're familiar with the dull, one-dimensional yellow that remains after bleaching. It's not an especially natural or flattering shade, which is why a good colorist will then apply highlights, lowlights and toner. (Side note: This is also why your salon visit takes four hours and costs a small fortune.)
What is purple shampoo?
The product goes on, you guessed it, purple — a bold, somewhat-alarming violet that will stain your bathtub if it dries — but rinses out clear. For about five minutes in between, that pigment works to neutralize those brassy shades with its magical, opposite-end-of-the-color-wheel powers, explained hairstylist Susan Monahan of Warren-Tricomi Salon.
And get this: It works. While an over-the-counter product can't replicate the nuanced work of a skilled colorist, it can help keep that blond shade bright for months, helping you stretch out the time between salon visits.
"It's great for cutting the brassiness in blond hair, especially in city areas where there tend to be a lot of mineral and rust buildup in water," celebrity colorist Ryan Pearl of Cutler Soho salon told TODAY.
It can also help neutralize yellows or gold to make blond shades appear brighter, added Victoria Hunter of Whittemore House Salon.
But it's not just for blondes. It can also be used to touch up highlights, keep trendy pastels looking crisp or give grays (natural or otherwise) those chic blue undertones.
So, what's the catch? Well, there is the aforementioned tub staining, so be sure to clean up quickly. Plus, "covering an entire head of hair in the shower with a stain is tricky," Monahan explained to TODAY. "Most people don't add enough shampoo to really coat every hair."
And it is possible to go overboard. Pearl recommended using it just once a week, maximum. You can use one of our favorite drugstore shampoos on the other days.
With that, here as some purple shampoos to try. Let us know how it goes!
The best purple shampoos
Reviewers on Ulta raved, "I bought this product to take out the brassiness of my colored hair. Normally dark brown roots but I have balayage to basically platinum blonde and HELLO. I could tell the difference in my hair in ONE wash. This shampoo is amazing. I've used it twice so far this week (I only wash my hair about 3 times a week anyways) and it really does the job. Follow the directions on the back tho, lather it in your hair and LEAVE IT IN (it says max 5 minutes so I would keep it in the max). If you do not leave a purple shampoo in your hair and let it do it's job then you will not see results! Would buy it again for sure!"
As one reviewer put it, "After using 10 different purple shampoos this one is by far the best. Removes brass in ONE wash. I like to leave it in my hair while I shower to tone out even more! Lathers extremely well, smells great, and does not completely dry out your hair. A little goes a long way with its deep pigment!"
One Amazon reviewer wrote, "I can't live without this. I dye my hair myself after a disastrous trip to a salon left me with fried hair that started falling out and a blustery burn on my head. I have a lot of natural red in my dark blonde hair and dye it light blonde every 4-6 weeks. It turns bright red, and this saves the day every time! I also love the smell of it.
Ulta reviewers have given this 4.4 stars and over 800 glowing reviews. "I use this shampoo with the conditioner every other shower and it truly takes the brassy tones out of my blonde hair. The exact reason I bought it! It leaves my hair soft and shiny and keeps tangles out which is very difficult for my fine hair, definitely going to purchase again."
"Smells nice and keeps my hair a great shade of blonde! I have ash blonde highlights and this shampoo helps to keep the colour looking fresh. I don't find the smell too strong compared to other purple shampoos. I also find it a better consistency as some purple shampoos are too runny. I would definitely recommend this product," wrote one Sephora reviewer.
The best purple conditioner
This is Monahan's go-to conditioner for blonde hair, which gives a similar effect as a purple shampoo.
