Quick answer: an antioxidant shampoo cleanses like any shampoo, but its formula also contains antioxidant ingredients that help protect the hair fibre from everyday environmental stress: sun, sea air, wind, chlorine and pollution. The result is hair that looks healthier, brighter and shinier, especially if yours has started to look dull. Insight's vegan Antioxidant Shampoo is made for all hair types with organic carrot extract, rich in beta-carotene, plus soybean, hazelnut and jojoba oils and shea butter. Pair it with Antioxidant Hair Conditioner and a weekly Antioxidant Hair Mask for the full routine.

Most shampoos are chosen for a hair type: dry, oily, coloured, curly. Antioxidant shampoo is different. It's chosen for what your hair is exposed to. If you commute through a city, swim regularly, spend time outdoors or simply feel your hair has lost its shine, it's worth understanding what it does.

What do antioxidants do for hair?

Sunlight, pollution and other everyday aggressors create unstable molecules called free radicals. Over time they contribute to the hair fibre becoming rougher, drier and duller. Antioxidants are ingredients that help neutralise free radicals before they cause that wear and tear.

In haircare, that means a formula that doesn't just remove dirt and build-up, but also helps defend the lengths from the environment they're exposed to every day. Carrot extract is a good example: it's naturally rich in beta-carotene, a well-known antioxidant.

Who should use an antioxidant shampoo?

  • City dwellers and commuters: pollution settles on hair every day.
  • Swimmers: chlorine is tough on the hair fibre, leaving it dry and dull.
  • Outdoor lifestyles: sun, wind and sea air add up over a season.
  • Anyone with dull, lacklustre hair: the formula helps brighten dull lengths and restore shine.

Because Insight's Antioxidant range is made for all hair types, you don't need to have a particular hair "problem" to use it.

Why does hair look dull in winter?

Dullness isn't only a summer issue. In winter, central heating dries the air indoors while cold wind roughens the hair outdoors. A rough hair surface reflects less light, so hair looks flat and lifeless. Hats, scarves and collars add friction too. An antioxidant routine with a nourishing conditioner and a weekly mask helps smooth and soften the lengths so shine comes back.

The Insight antioxidant routine

  1. Shampoo with Antioxidant Shampoo: apply to damp hair, massage to spread evenly and rinse thoroughly.
  2. Once a week, mask: squeeze out as much water as you can, apply Antioxidant Hair Mask to the lengths and ends, leave for 5 to 10 minutes and rinse.
  3. Condition with Antioxidant Hair Conditioner: apply to damp hair, leave for 3 to 5 minutes, then rinse. It detangles and leaves hair soft, easy to comb and glossy.
  4. In summer, add Protective Hair Spray, a lightweight leave-in conditioning milk that helps defend hair against sun, sea salt, chlorine and pollution while keeping it soft and hydrated.

Frequently asked questions

What does antioxidant shampoo do?
It cleanses the hair and scalp while antioxidant ingredients help protect the hair fibre from environmental stress such as sun, pollution, wind, sea air and chlorine, keeping hair healthy-looking and shiny.

Is antioxidant shampoo good for dull hair?
Yes. Insight's Antioxidant Shampoo is designed to brighten dull lengths, and the matching conditioner and mask restore softness and shine.

Can I use antioxidant shampoo every day?
It's made for all hair types, so you can use it as your regular shampoo. If your hair gets oily quickly or feels weighed down by build-up, alternate it with a shampoo made for your scalp.

Does antioxidant shampoo protect hair from the sun?
It helps defend hair from environmental stress, but it isn't a sun protection product. On sunny days and holidays, use a leave-in like Protective Hair Spray and cover your hair with a hat for long periods outdoors.

Is antioxidant shampoo good for swimmers?
Yes. The Antioxidant range helps protect the hair fibre from chlorine. Wetting your hair with clean water before you swim and washing it soon afterwards helps too.

Is antioxidant shampoo good for coloured hair?
If your main concern is keeping colour vibrant, choose a shampoo made for colour-treated hair, like our award-winning Protective Shampoo, which helps protect colour from fading.

What is antioxidant conditioner?
A conditioner with antioxidant ingredients that nourishes, detangles and helps protect the hair from external aggressors. Antioxidant Hair Conditioner uses the same carrot, soybean, hazelnut, jojoba and shea blend as the shampoo.

Is Insight's Antioxidant range vegan?
Yes. Every Insight product is certified vegan by VeganOK, cruelty-free and made in Italy.
