Lush are very strict about their manufacturing. They invent every product, source every raw material carefully, and then make the bars by hand in their local factories worldwide.

The shampoo bars lather and clean well, there is no residue, and each bar lasts a long time. If you order online, their packing contains eco peanuts that dissolve in water and recyclable packing tape.

Since 2013, Lush donated £65 Million to various organizations and charities. They have five main Charity streams, which you can see here.

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.

Their shampoo bar works well, and it creates a lot of lather. However, it is essential to mention that they are NOT suitable if the water is hard where you live (with a high mineral content, usually calcium and magnesium).

The shells of the soap nut contain Saponin, which is a natural cleaning agent. When the nutshells absorb water, the Saponin is released, which creates a soaping effect, and it is ideal for washing hair.

Soap nuts add shine to your hair and make it smooth. They are also a good option for scalp infections since the soapnuts are antimicrobial.

The easiest way to use soap nuts to wash your hair is – blend 10-15 soap nuts with a bit of vinegar and water. Then, strain and use instead of shampoo. Know that it will not lather, but it will clean the hair.

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, 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 of the companies have hair quiz 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.
