If you have blonde hair in Queenstown, you already know the struggle. Hard water, alpine sun, chlorine from the lake — your colour is fighting battles on multiple fronts. Purple shampoo is one of the most powerful tools in your at-home haircare arsenal, but most blondes are either not using it enough, or using it so much they have gone grey. At Iron and Ivy Hair Studio in Queenstown, this is one of the questions we answer at almost every blonde appointment.
What Does Purple Shampoo Actually Do?
Purple shampoo deposits violet pigment onto the hair shaft to neutralise brassy, yellow, and orange tones. It works on the colour wheel principle — purple sits opposite yellow, so the two cancel each other out. It is not a treatment, it is a toner in shampoo form. It will not repair damage, add moisture, or strengthen your hair. It simply removes warmth and keeps your blonde looking cool, fresh, and salon-finished.
At Iron and Ivy Hair Studio Queenstown, we recommend purple shampoo to every single blonde client — whether you are a natural blonde, a balayage client, or someone with full highlights. The difference between a blonde who uses it correctly and one who doesn’t is visible within two weeks of leaving the salon.
How Often Should You Use Purple Shampoo in Queenstown?
The honest answer is: it depends on your blonde. But as a general rule for Queenstown clients:
- Once per week for most blondes maintaining cool tones
- Twice per week if you swim in the lake or pool regularly, or if your hair is very porous
- Every second wash if you are freshly bleached and need to hold your toner
- Once per fortnight if you have very cool, ashy blonde that is already sitting perfectly
Queenstown’s alpine water can be mineral-heavy depending on your suburb, and this contributes to brassiness building faster than it might in other parts of New Zealand. Our Iron and Ivy stylists often recommend slightly more frequent use for clients in certain parts of Queenstown for this reason.
How Long Should You Leave Purple Shampoo On?
This is where most people go wrong. Purple shampoo is not a set-and-forget situation. Timing matters enormously:
- 3–5 minutes for regular toning maintenance
- 10–15 minutes if your hair is very brassy or you have missed a few weeks
- Never more than 20 minutes — at this point you risk staining, particularly on very porous or bleached hair
A common mistake we see at Iron and Ivy Hair Studio is clients leaving purple shampoo on while they shave their legs, do a face mask, and scroll through Instagram. Twenty minutes later they rinse off and wonder why their blonde looks lavender. If your hair has turned purple, it means the pigment has over-deposited. The fix is a clarifying wash and a deep condition, but prevention is easier.
Which Purple Shampoo Do We Recommend at Iron and Ivy Queenstown?
Not all purple shampoos are created equal. The supermarket versions are typically weak on pigment and heavy on sulphates, meaning they strip moisture while barely touching the brassiness. At Iron and Ivy Hair Studio in Queenstown we work with professional-grade products and recommend our clients do the same.
Our top picks for Queenstown blondes:
- Moroccanoil Blonde Perfecting Purple Shampoo — our most-recommended for high-maintenance, bleached blondes who need serious toning power
- Amika Bust Your Brass Cool Blonde Shampoo — excellent for natural blondes and those with highlights who need gentle, consistent maintenance
- Moroccanoil Color Extend Blondage — a strong performer for clients who want fast results with minimal leave-on time
Come into Iron and Ivy Hair Studio in Queenstown and we will help you find the right match for your specific blonde. What works brilliantly for a cool, platinum client will not be right for a warm, honey balayage.
Purple Shampoo Mistakes to Avoid
- Using it on dry hair without rinsing first — always wet hair thoroughly before applying
- Skipping conditioner — purple shampoos can be drying, always follow with a moisture-rich conditioner
- Using it too close to a fresh colour appointment — wait at least 48 hours after a toning service
- Applying unevenly — work it through every section carefully, especially the mid-lengths and ends where brassiness tends to sit

Frequently Asked Questions
How often should I use purple shampoo on blonde hair?
Once or twice a week is the sweet spot for most blondes. Leave it on for two to five minutes rather than the full shower, then rinse thoroughly. Used too often or left on too long it can tip your hair grey or muddy instead of bright and cool toned.
Why does blonde hair go brassy?
Brassiness happens when the warm pigments left in the hair after lightening are exposed to water, heat, and UV over time. It is a completely natural process and not a sign that anything went wrong. A quality toning shampoo used regularly and an occasional in-salon gloss treatment keeps it in check between appointments.
Is box dye bad for your hair?
Box dye is not inherently dangerous, but it is formulated to a single strength designed to work across many different hair types, which means it often over-processes some areas and under-processes others. It also makes future professional colour corrections more complex and expensive. For anyone considering going lighter or making a significant colour change, a salon service gives a more predictable and healthier result.
What is a colour consultation and do I need one?
A colour consultation is a conversation before we touch your hair. We look at your current hair, understand your history, talk through what you want to achieve, and give you an honest view of what is possible and what it will cost. For any colour service, especially if you are changing your look significantly, it is an essential step rather than a formality.
How do I keep my colour looking fresh between appointments?
Wash with cool or lukewarm water, use a colour-safe shampoo and conditioner, and apply a UV-protecting product before spending time outdoors. The UV in Queenstown is stronger than most people expect, even in winter, and it is one of the fastest ways colour fades. A weekly hydrating mask keeps colour-treated hair in good condition throughout.
