How much water is in bottled shampoo? Why concentrated shampoo bars are better

Do you know how much water is in a typical bottle of shampoo, compared to a concentrated shampoo bar? And why should this matter to you anyway?

If you’ve ever taken a closer look at the ingredients listed on the back of your shampoo bottle, you’ve probably asked: what exactly am I paying for here?

Or, perhaps you’ve heard of concentrated shampoo and want to know more about its benefits. 

Read on to learn how much water is really in your shampoo bottle, and why using a concentrated shampoo bar is a much better option.

Is there really water in my shampoo bottle?

Have you seen the word ‘aqua’ on the back of your shampoo bottle? It actually just means water. Yep, exactly the same stuff that comes out of your tap.

A shampoo bottle is certainly not the only beauty product to contain water as an ingredient. In fact, the personal care aisles of our supermarkets are full of watery liquids in plastic bottles. We won’t get started on the plastic issue now, but if you’re interested take a look at our blog post all about what makes KIND2’s plastic free shampoo so sustainable.

Why do bottled beauty products contain water?

We live busy lives, and we tend to buy items that are convenient and available to us. Since there are so many items that contain water, bucket loads of them manage to find their way into our shopping trolleys every day. But what is water doing in these bottles?

The reason it’s such well-used ingredient is simply that it’s:

  • Extremely cheap
  • Keeps profits high
  • Bulks out products

Essentially, we are being fooled. We might think that we’ve bagged a great deal when we buy a huge bottle of shampoo at a cheap price. In reality, however, we’ve spent money on the substance that’s on tap in our homes 24/7.

You might be thinking … but bottled shampoo does clean my hair effectively, so it must contain mostly essential ingredients. How much are we really being duped?

How much water is in bottled shampoo?

The amount of water in a typical bottle of liquid shampoo might come as a surprise to you.

Astonishingly, bottled shampoo is actually made up of between 75 to 85% water. 

Considering that we use shampoo in the shower, where litres of water pour onto our heads, this is a crazy and extravagant waste of money!

It means that when you buy a bottle of shampoo, you’re basically paying for a plastic bottle of (primarily) water. The liquid will have an extremely low concentration of active ingredients in it.

If you feel cheated, you have a right to. Still, now that you know, you can begin to get your money’s worth by switching to plastic free solid shampoo bars.

KIND2’s solid shampoo bars and solid conditioner bars are concentrated

Using a concentrated shampoo bar is a simple and completely effective way to avoid the bottled shampoo issue.

The KIND2 journey actually began with a search to find innovative solutions to reducing plastic waste. Learning how much water is in bottled shampoo made us realise that creating a hair washing alternative would decrease the amount of plastic on our planet.

That’s why none of KIND2’s plastic free solid shampoo bars and solid conditioner bars contain water. Instead, they’re made from concentrated, active, plant-based ingredients.

So, by using KIND2’s solid shampoo bars, you will cut down on polluting single use plastic and save money at the same time.

Other benefits to using KIND2’s concentrated solid shampoo bars

Your bank balance is not the only thing that will benefit when you switch to a concentrated KIND2 shampoo bar. Our solid shampoo and conditioner bars are also: 

  • Great for your hair’s health. The powerful natural ingredients they contain will soothe your scalp, fully cleanse your hair and keep it shiny.
  • Long lasting. Because solid shampoo bars are so concentrated, they last 2 to 3 times longer than bottled shampoos. Depending on your hair type, you might even be able to eek it out further.

Great Conditioner!

I love this bar! It leaves my hair tangle free and so soft! I was super impressed the first time I used this as I thought it wouldn't do much for my thick hair, but I was wrong it really is a fab conditioner and you don't need much at all. Hence the bar seems to go on forever, great value for money!

Great for Itchy Scalp!

I was always a bit sceptical about shampoo bars but once I tried Kind2 I'm sceptical no more! I have an itchy scalp which gets irritated very easily so I have to be careful what I use. The Sensitive one is very gentle and perfume free so it doesn't upset my scalp and the bar lasts for ages! Added bonus is that because it doesn't contain any nasties it doesn't strip coloured hair either. It leaves hair soft and shiny to the point where my neighbour commented how shiny my hair was the other day and seeing as I haven't been to the hairdresser since December that's pretty impressive!

Simply just the best shampoo bar on the market!

This is my third purchase of this shampoo bar - and I totally LOVE IT! I have long, think hair and have struggled to find "the one" that works for me. And now I have. It makes my hair feel so much more healthier. As I struggle with a very sensitive scalp the natural ingredients make a real difference, sulphate free is the way to go. Am sure you can tell, this shampoo bar comes highly recommended from me :-)


I just love this company, their commitment to the planet and to people. I am adjusting to the shampoo. I cannot get any lather. The conditioner, it feels like I haven't done anything. But, my hair looks and feels great afterwards. So I'm sticking with it

Love it!

To be fair, I have only used the shampoo and conditioner bars a few times. I can already see a feel a difference. My hair has become a bit thin on top and I’m now having to deal with it frizzing terribly. Since using these bars, I have had no frizzing and my hair feels thicker. Now I know that it hasn’t miraculously thickened but it looks and feels that way. I’m hoping that with regular use, my hair will start growing again where there are thin patches, but time will tell. I am really happy with these bars and will continue to buy them. Don’t expect lather because there isn’t any, but my hair feels cleaner than when I’ve used regular shampoo. Love it!
