Nice Tone, Gentle Formula
Most purple shampoos dry out my scalp, but this one feels super gentle and doesn’t strip my hair. The toning is subtle but builds up nicely with consistent use.

Brass-Free Blonde Again!
I’ve tried a ton of purple shampoos, but this bar is a game-changer. It toned down the yellow in my blonde hair after just one use! Plus, it smells amazing and lasts forever. Never going back to liquid bottles again.

Purple shampoo bar
I have dark blonde hair with highlights that tend to get yellow-toned in between my hair appointments, so I use a purple shampoo to bring it back to a cooler tone. This shampoo bar works and hasn't irritated my sensitive scalp. No complaints here!

Blonde Ambition, Purple Precision

Tone down the brass, turn up the brilliance with purple shampoo

What does purple shampoo do?

Purple shampoo is designed to neutralize yellow or brassy tones in blonde, silver, or highlighted hair. The purple pigment counteracts the warmth that can develop over time, helping maintain a cooler, brighter hue between salon visits.

Can I use purple shampoo on brown hair with highlights?

Yes! If you have blonde or lightened highlights in brown hair, purple shampoo can help tone down brassiness in those lighter sections, keeping your color fresh and balanced.

Is your purple shampoo bar safe for daily use?

Absolutely. Our formula is gentle enough for regular use thanks to its nourishing, SLS-free blend. But for color toning, we recommend alternating with a moisturizing shampoo bar to maintain balance.

How does purple sweet potato powder tone hair?

Nature’s color wizard! Purple sweet potato powder is rich in natural anthocyanins — the pigments responsible for its vibrant hue. These naturally help neutralize yellow tones in hair, without relying on synthetic dyes.

What makes your purple shampoo bar different from others?

We combine natural toning agents like purple mica and sweet potato powder with ultra-moisturizing ingredients like cocoa butter, shea butter, and castor oil. Plus, we use coconut-derived cleansers instead of sulfates like SLS, making our bar both color-safe and scalp-friendly.

What’s the benefit of Bhentrimonium Methosulfate in your shampoo bar?

Despite the long name, it's actually a super gentle conditioning agent derived from rapeseed oil. It helps detangle, soften, and smooth hair without buildup, making it perfect for damaged or color-treated locks.

Will it lather like traditional shampoo?

You bet. Thanks to Sodium Cocoyl Isethionate (SCI) and Sodium Methyl Cocoyl Taurate, our bar offers a creamy, satisfying lather — minus the harshness of traditional foaming agents like SLS.

Is your purple shampoo bar safe for sensitive scalps?

Yes! Aloe vera and marshmallow root extract work together to calm irritation, reduce dryness, and keep your scalp as happy as your hair. Lavender and chamomile essential oils add a gentle, soothing touch.

Is your purple shampoo bar safe for color-treated hair?

Yes! In fact, it’s made for color-treated hair. Our SLS-free formula helps preserve your salon color longer by gently cleansing without stripping. Plus, the toning ingredients help keep that just-dyed brightness going strong.

Can I travel with this shampoo bar?

Absolutely. No leaks, no airport liquid limits, and no plastic bottles rolling around your suitcase. It’s the ultimate travel-friendly toning solution.
