The scoop on purple shampoo. What it is, how it works and why you need it.

The scoop on purple shampoo. What it is, how it works and why you need it.

What does purple shampoo do?

We specifically formulated our purple shampoo - Blonde Moment™ Shampoo - with water-soluble purple pigments that deposit onto hair to effectively reduce any yellow or brassy tones for natural or dyed blondes, highlighted and gray hair. It’s also based on a gentle surfactant system, which means it’ll do what shampoos do (cleanse) without drying strands. Say hello to maintaining salon fresh color in-between visits!

How does purple shampoo work?

You’re probably wondering why such a shampoo exists. It’s simple science! But, to make a long story short, it’s all based on color theory. Think back to the color wheel you saw in art class as a kid. If you look closely, purple and yellow are directly opposite of each other. When combined, these two colors “cancel” each other out, leaving behind the neutral tones we know and love in our hair color.

Why does brass occur in the first place?

Because bleach. The process of chemically lightening hair is pretty cool, honestly. The cuticle of the hair is “opened” so that some of the pigments (what gives your hair its natural hue) may be removed to make your desired blonde/lightened color possible. And even though that process of removing those pigments is really successful, there are always some leftovers in your hair shaft. We have those leftover pigments that won’t go anywhere to thank for that warm brassy, yellow tinge that marks a fresh bleach job. It’s easy in the salon chair to combat that brass through application of a toner, which ensures that the brass is kept at bay and target color has been achieved. You leave the salon looking and feeling fresh as ever, with no sign of brass anywhere.

And then life happens. AKA repeated washing, heat styling, UV exposure... you name it. That new ‘do (that probably cost a pretty penny) and toner begins to fade, revealing those brassy-yellow pigments that have stuck around all this time. For those with lighter base shades, your brass will resemble a more yellow tonality. By working our Blonde Moment™ purple shampoo into your weekly wash routine, you can bust that brass without breaking the bank.

For darker or brunette base shades that yield a markable more orange vibe – opt for our Triple Threat Brunette™ Blue Shampoo, instead!

How do you use purple shampoo?

While the whole color theory process may be a tad confusing, using Blonde Moment™ Shampoo is not. We suggest incorporating a purple shampoo into your routine by occasionally using it in place of your regular shampoo. Just like your go-to shampoo, you know the drill on how to use it, too – lather and work into wet hair. Rinse thoroughly and follow with your favorite NYM conditioner.

How often should you use it?

How often to apply will depend on how much you wash your hair with regular shampoo. Maybe that’s once a day or once a week. For you and your blonde, you can land anywhere in-between the two. Frequent washing can lead to notable brass a little faster than those who wash less. It’s pretty safe to say this - The more times you’re getting your hair wet, the more often you’re going to need to tone. We recommend starting by using our purple shampoo 1-2 times a week or as needed.

3 tips from Madison for maintaining your fresh blonde.
  1. Wash less. Struggling with oily roots? Grab some Blonde Moment™ Dry Shampoo.
  2. Skip the hot tools. Go ahead, throw your hair in a braid or high pony instead of hitting it with a curling iron or straightener.
  3. Treat yourself. Not wash day, but your hair is looking a little brassy and feeling dry? Grab our Purple Toning Hair Mask to fight those yellow tones and add extra moisture back in your hair.
