Each bar lasts around 50+ washes, and both the shampoo and conditioner bars are unisex and work great for all hair types. The shampoo bar provides deep moisturizing while strengthening your hair.

I haven’t tried their bars, but from reading the reviews, I can see that people love that they lather very well, and the smell is fantastic.

Lastly, Eco Roots is 1% For The Planet Member, donating 1% of their sales to sustainable initiatives and organizations like Ocean Conservancy. So far, they’ve donated $10,776.

Ethique is a 100% plastic-free and climate-positive company that offers palm oil-free & vegan shampoo bars & conditioners. Ethique is a Certified B Corporation,

They have sampler packs and provide all their products in sample sizes, so you don’t have to commit to a full bar immediately and find the perfect one for you.

Unfortunately, when I wanted to buy it, they didn’t deliver it to Europe (yet). However, I would love to try Ethique in the future.

Plaine Products sell refillable liquid shampoo in aluminum bottles. The amount is 16 oz (473 ml), and it lasts about 2-3 months. They also have small Travel-sized bottles (2.5 oz), which are ideal if you want to try a sample first and see if it works for you.

I’ve tried various shampoo bars from Lush, including Soak and Float, Jason and the argan oil, Montalbano. While their bars are more expensive than other options locally, I notice that Lush shampoo bars work much better on my hair. 

Other cheaper bars leave residue, cause me itchy scalp, and last for a shorter period. 

Humankind shampoo bars are suitable for all hair types and are cold-processed. This soap-making process helps retain more glycerin, which helps moderate pH, making the bars ideal for sensitive skin. 

It is 100% safe for colored or treated hair. Each bar has a five-week curing period, which allows excess water to evaporate, creates a highly concentrated formula, and helps the bar hold its shape over time. 

Humankind has 4oz solid shampoo bars (4 options) and liquid ones in an 8.5 oz/251 ml aluminum bottle (2 options).

Tips on picking shampoo & conditioner bars for you:

• Sometimes you will see mixed reviews for a product. That’s often because it depends on the hair type, and sometimes, what works for me, won’t work for you. I’ve tried various Lush bars, for example, and a couple of them have a lot of negative reviews, but for me, the bars worked perfectly, and I was happy with them. 
• You may need to try several different brands and trial and error different ingredients. Everyone is different, and not every product will work well for every person. If a product doesn’t work for you, try using it for something else, like washing your hands or body or shaving cream. Or you can give it to a friend and try a new one. 
• More expensive doesn’t always equal better. However, I’ve tried a few more affordable brands, and I always ended up going back to the more pricey ones. They simply work better for my hair. 
• Most companies have hair quizzes on their website. When you take it, they can help you to discover a personalized haircare routine.

FAQ:

Why choose a sustainable shampoo?

Sustainable shampoos don’t use any unnecessary chemicals. They are made with various plant extracts, herbs, essential oils, and other natural ingredients, which gently clean the hair. They are better both for you and the planet. 

What to look for when shopping for eco-friendly shampoo & conditioner? 

When searching for eco-friendly shampoo bars and conditioners, look for products that are:

• Made with safe and sustainable ingredients and the packaging is plastic-free.
• If the company is certified by a third-party standard requiring companies to meet social sustainability and environmental performance standards, it is a plus. 
• The company is a member of organizations that protect the planet.
• The company donates money to various environmental or social causes.
• The company offsets its emissions.

How to store shampoo bars to avoid them turning into mush in the shower?

Store your shampoo bar dry, away from direct water. Keeping the shampoo bar and conditioner dry off between uses is essential to keep them in good shape. It’s best to keep them on a well-draining surface that allows lots of airflow around it.

Do shampoo bars have a shelf life? 

It is best if you use the shampoo or conditioner bars within 6-12 months. The more natural, organic options usually have a much shorter shelf life. If the shampoo or conditioner starts smelling differently or the consistency/color changes, it could mean that the bar is expired.

Do shampoo bars leave a residue?

Not all, but some shampoo bars can leave an odd, waxy residue. This residue is a byproduct of saponified oils, which a lot of shampoo bars contain. 

To get rid of it, you can do an apple cider vinegar rinse (mix 3-4 tbsp of apple cider vinegar with 1 cup of water), which will remove any unwanted residue.
