New Zealand’s UV Problem
New Zealand sits close to the ozone hole above Antarctica, meaning UV radiation levels here are significantly higher than in comparable latitudes elsewhere in the world. For your skin, you already know to wear sunscreen — but your hair needs protection too.
How UV Damages Hair
UV radiation breaks down the keratin proteins in your hair shaft, causing dryness, brittleness, and split ends. For colour-treated hair, UV is particularly damaging — it oxidises colour molecules, leading to fading, brassiness, and dullness far faster than it would indoors.
Blonde and Lightened Hair Is Most Vulnerable
Lightened or bleached hair has already had some of its natural pigment and protein removed. This makes it more porous and more susceptible to UV damage. If you’ve just had a beautiful balayage or blonde service at Iron + Ivy, protecting it from the sun should be a top priority.
How to Protect Your Hair from UV
- UV protection spray: Applied like a leave-in conditioner, these sprays create a barrier against UV rays. Reapply after swimming or extended outdoor time.
- Hats: The most effective protection — wide-brimmed styles cover both your hair and scalp.
- Tinted hair products: Some conditioners and masks contain UV filters that protect while nourishing.
- Avoid sun at peak hours: Hair is most vulnerable between 10am and 4pm when UV is most intense.

Frequently Asked Questions
Does UV radiation actually damage hair in New Zealand?
Yes — New Zealand has some of the highest UV levels in the world due to a thinner ozone layer, high summer sun angle, and clean atmosphere. UV degrades the hair’s keratin protein and causes colour to fade faster than in many other countries.
What are the signs of UV damage in hair?
Dryness, brittleness, a rough texture, faded colour (especially in blondes and colour-treated hair), and loss of elasticity are the most common signs. Over time unprotected UV exposure can permanently lighten and weaken natural hair pigment.
What products protect hair from the sun?
Look for UV-filter sprays, leave-in conditioners with SPF, and products containing UV-absorbing compounds. Moroccanoil Sun After Sun Treatment is formulated specifically for post-sun repair. Physical cover — a hat or scarf — is still the most reliable protection.
Does sun damage hair more in summer or year-round in Queenstown?
Queenstown gets intense UV year-round, but summer and the ski season (snow reflection amplifies UV significantly) are the peak risk periods. Skiers are especially vulnerable as UV increases with altitude and snow can reflect up to 80% of UV back onto you.
Will a UV protection product affect my hair colour?
Good UV protection should actually preserve your colour by slowing down the photo-oxidation process that causes fading. Protecting your investment in professional colour with a UV-filter product is one of the most cost-effective things you can do between appointments.
Is colour-treated hair more vulnerable to UV?
Yes. The colour process raises and opens the cuticle, making the hair shaft more porous. UV penetrates more easily into porous hair, causing both colour fade and protein degradation faster than on virgin hair.
