Zero Waste Conditioner: A Sustainable Way to Achieve that Silky Shine

We all want that hair commercial moment. The head whip that causes silky tresses to swirl forward, or running a hand through hair that cascades perfectly into place. That moment most commonly brought to you by conditioner. 

Yet traditional conditioner comes with plenty of pitfalls. If you thought the ingredients in commercial shampoo were indecipherable, conditioner is no better, and its packaging is no more sustainable.

Even when recycling is possible, only 1 in 5 people consistently recycle bathroom packaging, according to a study commissioned by Johnson & Johnson.

Fortunately, there’s an abundance of zero waste conditioner options available that are made with natural and beneficial ingredients. Keep reading to learn how to ditch plastic bottles for bars, refills, masks, or DIY conditioning solutions.

Zero Waste Conditioner Options

When choosing which plastic-free conditioner is right for you, think about how it will fit into your existing routine.

If you’ve already committed to switching to zero waste shampoo bars, following up with a solid conditioner bar will come naturally. If you can’t quite imagine ditching the liquid conditioner just yet, refillable options could be your saviour.

ZERO WASTE CONDITIONER BARS

Long-lasting, eco-friendly, and packed with natural ingredients, there’s a reason conditioner bars are one of the most popular forms of plastic free conditioner.

Just run your bar of choice along your hair and massage it in, or use water to create a creamy lather first. Rinse it out, and your hair will be left moisturized and soft. 

Here’s our pick of the best zero waste conditioner bars.

EcoRoots Conditioner Bars

EcoRoots plastic free conditioner bars come in a range of heavenly scents, and are all formulated to leave your hair and scalp wonderfully nourished and soft.

ZERO WASTE REFILLABLE LIQUID CONDITIONER

Understandably, some prefer liquid conditioner for its ease of application and storage.

ZERO WASTE CONDITIONING MASKS

When your hair really needs a good dose of moisture, a once or twice weekly conditioning mask will do the trick.

Apply a zero waste hair mask to damp hair after using your plastic free shampoo, and towelling dry. Starting with the roots, spread it throughout, and let it sit for the recommended time before rinsing, using a shower cap or towel to cover the hair for extra effectiveness. Wash the mask out with zero-waste shampoo and follow with your normal plastic free conditioner. 

Andreas Organic Market’s Organic Honey Hair Mask

This vegan hair mask deep conditions and repairs damage with its mix of avocado oil, raw honey, argan oil, pumpkin seed oil, and vitamin E oil. It’s made with organic ingredients and comes in an eco-friendly glass jar with a metal lid.

Although there are no refill options, everything is fully recyclable and even the shipping materials used are biodegradable.

But we think you’ll find plenty of uses around the home to reuse your little glass jar – like for storing your DIY beetroot lip stain!

DIY CONDITIONER

Even more than solid shampoos and other beauty products, a zero-waste, vegan conditioner can be simple and cost-effective to make.

An apple cider vinegar rinse can remove build-up and detangle hair. Melted coconut oil works as a once or twice weekly zero waste hair mask. And banana combined with olive oil or aloe vera can act as a leave-in treatment.

Making a liquid conditioner or bar, however, requires getting some kind of emulsifier and preservative – things you won’t find in a typical grocery store. But it’s fairly easy to source ones that are natural and eco-certified in online stores. So try your hand at this neat DIY!



Committing to zero waste hair care doesn’t mean leaving shiny, glamorous hair behind. In fact, the natural ingredients in zero waste conditioners are the perfect thing for nourishing hair back to health.

From the ease of a conditioner bar to experimenting with making your own, there’s a way for everyone to be kind to the environment, reduce plastic waste, and still get that perfect hair moment.
