Purple Shampoo for Blonde & Grey Hair
Gently lifts away dulling residues and brassy buildup, restoring your hair colour, leaving it luminous and refreshed.
External factors such as hard water and sun cause yellow and brassy tones, as well as colour fade, which can be hard to tackle. This is where this purple shampoo comes in.
Think of it as a weekly colour reset. Use it regularly to keep tones cool and consistent between salon visits, counteracting brass with every wash for hair that stays luminous and fresh.

Ritual & Philosophy
Rooted in Ayurveda, Made for Modern Life
In Ayurveda, hair colour reflects inner vitality. Caring for it is not vanity, it is an act of self-preservation. This Purple Shampoo for blonde hair honours that philosophy, pairing traditional botanicals like Castor Oil and Amla Powder with the toning power of Violet Pigments.
Modern life is not kind to colour. Colour-treated, bleached and naturally silver or grey hair needs consistent care as yellow tones creep back in with every wash. You likely notice it most after spending time outside in the sun or when showering with hard water that quietly dulls your colour day by day.
Regular purple shampoo bar use keeps tones cool and consistent, restoring vibrancy without harsh chemicals. In a consumer study*, 92% of users saw visibly more luminous colour after 28 days.

What is a purple shampoo?
A purple shampoo bar neutralises yellow and brassy tones in blonde, silver, grey and light-coloured hair.
How it works:
- Purple Shampoo Bar contains purple pigments that act as colour correctors
- Purple and yellow sit opposite each other on the colour wheel — purple cancels yellow
- Pigments adhere to the hair strand during washing, depositing a subtle violet tint
Yellow tones develop naturally over time due to sun exposure, hard water mineral buildup and hair dye fading. Regular purple shampoo bar use works as both a preventative and a maintenance routine, so your colour stays cool and balanced wash after wash.
How often should you use purple shampoo?
Arista's solid purple shampoo is gentle enough for regular use, but we recommend using it one to three times a week, not daily.
Purple pigments deposit colour with every wash and daily use can over-deposit pigment, leaving hair looking too ashy or grey. Light blonde and white hair are especially sensitive to over-toning.
How to find your frequency:
- Once a week: for subtle, low-maintenance toning
- Twice a week: for regular colour maintenance
- Three times a week: for stronger brassiness or freshly bleached hair
Less is more when it comes to toning.
How to use purple shampoo bar?
Here are a few easy steps you can follow to incorporate a purple shampoo bar into your hair-care routine:
- 1. Begin with wet hair.
- 2. Gently rub the bar between your hands or directly onto your scalp to create a soft lather.
- 3. Leave the shampoo on for at least 5 minutes for effective toning.
- 4. Rinse thoroughly, ensuring all shampoo is washed out.
- 5. Let the shampoo bar dry completely between uses. It's best to store it on a soap dish or in Arista's shampoo bar box to prevent staining surfaces and prolong its life.
What does purple shampoo do?
On wet hair, the shampoo bar's purple pigments cling to each strand. They deposit a subtle violet tint that cancels out yellow and brassy hues, restoring a cooler shade.
Can the purple toning shampoo bar replace my regular shampoo, or should it be used in conjunction with it?
Arista's solid purple shampoo is gentle enough to be used as your everyday shampoo.
What it does in one wash:
- Cleanses the hair and scalp
- Tones and neutralises yellow and brassy tones
- Nourishes with Castor Oil and Amla Powder
The toning pigments are balanced for regular use. However, for best results we recommend using it two to three times a week, in line with your hair's toning needs.
Can you use purple shampoo on brown hair?
Yes, you can use our purple toning shampoo bar on brown or dark hair, but it won't have any toning effects.
How long do the toning effects of the purple bar shampoo last with regular use?
In a 28-day consumer study, here's what we learned:
Toning effects aren't limited to a fixed number of washes — they build up and last with regular use.
Key results:
- 96% of users saw yellow tones visibly reduced after 28 days*
- Best results with 2 to 3 uses per week
- Regular use keeps tones cool and consistent over time

Is it safe to use this purple toning shampoo bar during pregnancy?
Arista's solid purple shampoo is pregnancy-conscious by design: no essential oils, no high-strength actives.
However, every pregnancy is different, so we always recommend consulting your healthcare provider for personalised advice before introducing new products into your routine.
