Expert Reviews

What experts liked

The shampoo is sulfate and paraben free so your hair isn’t left completely without all its natural oil. On the other hand, results have shown softer hair than before and a nice healthy shine that bleach often washes away from the hair. The shampoo is stronger than normal toning shampoos hence results may be visible a few minutes after application! If you are looking for the best hair toner to remove brassiness, this may be your answer.
A distinguishing characteristic of the Bold Unique Purple Shampoo is that it contains UV filters that protect from harmful sun rays. The shampoo also contains a formula that combats all hair problems, from color retention to dryness. Made in the best of conditions, this shampoo is cruelty-free and 100% vegan, with a money-back guarantee.
In my experience, it’s the best purple shampoo for white blonde hair. As the manufacturer states, this sulfate-free purple shampoo is suitable for gray, blonde, bleached, and highlighted locks to keep the color bright and radiant. The intense violet pigments help to combat unwanted yellow and brassy tones to leave you with beautiful silver ashy tresses.
This Purple Shampoo gives me amazing results just after first use. It reduces the brassiness to a great extent and Silver Shampoo gives instant bright and shimmering silver tones to my light blondes. It boosts the lighter tones of my hair and gives a refreshing and smooth look after every wash. The best part is its UV filter that doesn’t damage the ultraviolet radiation while maintaining my hair tones.
This one is actually one of (if not the) best I've tried.

What experts didn't like

Leaves the hair dry after use. A little pricey.
It is best used at least two weeks after getting hair bleached because color treatments make hair more porous, so the use of shampoo too soon after dyeing can make hair look patchy and uneven.
Since its formula is really strong, make sure to read and follow the paper directions, especially if you’re using this purple shampoo for blondes for the first time. You may want to wear gloves ‘cause the high concentration dyes hands and nails a bit.
Not suitable for use on other hair colors other than blonde.


Whether you were born with blonde hair or you pay for it, it can be tough to get the color just right. Even if it looks perfect the day you color it, it can gradually lose its luster and start to turn brassy. Those yellows, oranges and reds that make blonde hair look less brilliant than you’d prefer are hard to avoid.

Stylists typically add a toner to reduce those colors, known as undertones. But not everyone pays for salon color and, of those who do, the toner can lose its power over time. That means in the weeks following your appointment, you may find that your blonde takes on a bit of brassiness, which you’re stuck with until your next coloring.

That’s where purple shampoo comes in. If you look at a color wheel, purple is directly across from yellow, and colors located on opposing sides of the wheel cancel each other out. When purple is applied to your hair, it cancels out the yellow tones, providing that icy blonde color that is seen as the ideal.

But blonde hair isn’t the only hair color that can benefit from a tube of purple shampoo. Those with silver hair also find undertones starting to appear, and purple shampoo can help with that, as well. Some with dramatic blonde or silver highlights also find that purple shampoo provides better color, although it has no effect on other hair colors.
