12 Zero Waste Shampoo Bars That Really Work
Thinking about switching to a zero waste shampoo bar?
Here's what you need to know about the best shampoo bars and 12 of pebble's favourites that look after your hair and the planet.
According to a report, 520 million empty plastic shampoo and conditioner bottles are thrown out in the UK.
- They’re more economical as they last twice as long as bottled versions.
- They use up less water.
- They have a smaller carbon footprint.
- They come in biodegradable cardboard packaging.
Shampoo bars are a great way to embrace sustainable lifestyle choices at home and they’re one of the easiest steps to a plastic free bathroom.
Here’s why you should adopt zero waste shampoo bars into your haircare routine and 10 brands pebble loves that actually work.
Are shampoo bars better for your hair?
There’s always a bit of risk when trying a new hair or skincare product.
The best shampoo bar should be easy to lather up and rinse out with minimal water.
It should leave your hair feeling soft, healthy and nourished.
Some bars have a bit of a reputation of giving you a transition period where your hair may feel waxy or greasy.
It doesn’t last long though and a way around it is to use bars with good quality formulations that are specifically designed for your hair type.
On the whole, the right shampoo bar is better for both your hair and the planet as it’s free of plastics and harsh chemicals.
What are the benefits of using shampoo bars?
There are many amazing benefits to using a shampoo bar.
In fact, the right one can be a complete game-changer for your haircare routine. And not just for your hair, but your wallet and the environment too.
Here are some of the benefits of using shampoo bars
1. Saves you money. Shampoo bars can last twice or three times more than your average bottle of shampoo as the formula is more concentrated. For perspective, a bottle lasts about 25-35 washes and 80% of it is actually water.
2. Reduce plastic waste. A staggering 520 million empty shampoo bottles are thrown out in the UK. Many of them are made from single-use plastic. Shampoo bars are plastic free. In fact, they take it a step further by being zero waste. Once the product is gone there’s nothing to throw out. Most packaging is biodegradable FSC-certified cardboard too.
3. Lower carbon footprint. Shampoo bars have a lower carbon footprint than the liquid versions simply because of their size. A lorry full of bars holds roughly the same amount of washes as 15 lorries carrying liquid shampoo bottles.
4. They're often vegan friendly or use all natural ingredients. Good quality brands used ethically sourced, cruelty free and naturally derived ingredients which work with your hair to help it look its best. This is a much healthier option than using haircare products full of harmful silicones, sulphates and SLS that strip your hair of naturals.
How to use zero waste shampoo bars
Before applying any product, wet and detangle your hair as normal.
Then, you have one of two methods you can use.
You can either lather up the bar in your wet hands and massage the suds into your wet hair.
Or, another option is to gently wet the bar and apply it to wet hair, rubbing it in circular motions until you have enough lather to massage into your hair and scalp.
As a general rule, you’ll always need less than you think you need. Remember to rinse out your hair thoroughly too.
Should you use a conditioner after a shampoo bar?
It’s a good idea to condition your hair after using a shampoo bar as you would after the liquid version.
One exception is if the bar specifies that you don’t need a conditioner like Ethique’s St Clements or KIND2’s Two in One.
Conditioners help to replenish moisture and give ends a bit of TLC.
There are also conditioner bars available eg from KinKind if you don’t want to use liquid versions.
How to store shampoo bars
To make sure the shampoo bar lasts, keep it out of direct water flow and sunlight.
Ideally, put it on a soap rack that has holes to allow it to air dry. You can get racks that sit by the bath, or you can get ones that suction onto the wall or clip onto your shower.
If you're taking it away, store it in a metal or bioplastic tin or wrap it in a wax/soy wrap.
