What is a shampoo bar?

They’re firm, they’re pretty, they smell out of this world. AND it’s official, shampoo bars can outlive your favourite colored hair shampoos by three bottles!

They look like soap but are packed full of cleansing ingredients for your hair and are not as drying for your skin as traditional soap bars can be.

We love them because they contain high-quality, all-natural ingredients with no nasty chemicals or additives like sulphates that can dry your hair and damage your follicles.

They smell amazing too!

Your hair needs some time to get used to using them, so you may find your hair feels ‘coated’ or waxy at first. But push on through and you’ll never look back.

Why use a shampoo bar?

There are lots of benefits for using them for dyed hair in place of your normal color shampoo – at home or while travelling:

  • They’re a compact size and handy to carry around to work, the gym and on your travels.
  • They contain no nasty chemicals or additives.
  • Some can be used on your body.
  • They’re eco-friendly with no plastic packaging.
  • They’re budget friendly too.
  • They last so much longer than bottle shampoos.

There can be some downsides to using them too, but it can depend on the type and texture of your hair:

  • It can take some time for your hair to adjust to using it.
  • Some have a waxy consistency which can build up in your hair.
  • They can cause tangles in very long or fine hair.
  • They can leave you hair with a ‘coated’ feeling.

What is the best shampoo bar for color treated hair?

They’re cheap, they’re eco-friendly and they last 3 x as long as bottle shampoo. We’ve searched and scrubbed the land to find the best one for colored hair. These are the best of the best!

“I’ve tried other bars which have left my hair feeling greasy and waxy. I’d almost given up on the idea of shampoo soap bars until I came across this! I’ve liked these so much I’ve ordered more!”

“I live in a hard water area and washing other ones out was a nightmare. After the reading the reviews I thought I’d give these a try and so glad I did! It lathers up well, washes out easily and leaves the hair clean, all with a great smell.”

“I do need to use a little conditioner on my hair after using these, but I have colour treated hair so it’s always dry. The soaps do last ages so I should be set now for a long time, which is better for the environment too!”

Our experience:

These cleansing bars from Faith in Nature are gorgeous and come in a range of smells and rich formulas to suit every whim – from Lavender and Geranium, Shea and Argan, and Coconut and Shea butter.

“This smells amazing and leaves my hair soft and silky!”

“I found this so soft and gentle on the bleached ends of my hair. I have no product build up anymore after using this and I love that it’s safe for the whole family to use too.”

Our experience:

What’s great about Ethique’s range is that you can choose the right bar for your hair type – from Oily to normal to dry and frizzy.

We picked the one for frizzy, dry damaged hair as the best for colored hair.

It smells amazing and the coconutty goodness felt super luxurious on our hair.

Our experience:

The Shine on range comes in the most delicious range of scents for all types of hair – from mint to coconut to cinnamon to citrus.

There’s one for swimming, one for blondes and even one for all the family to share (although you might not want to!) Shine On have got it covered.

Best of all, they really work! And that’s why the reviews are awesome too.

We chose Shine On Bounty Hunter for dry and damaged hair and the results were clean tresses with gallons of gloss.

The dinky bar contains lemon oil which smells amazing adds the shine and sleekness. Coconut oil nourished our hair so well, we only needed a light conditioner.

Don’t be put off with advice of putting vinegar in your hair. This is a top tip to restore the ph balance in your hair.

Buyer’s guide: How to choose the right shampoo bar for you.

People are finding shampoo bars to be a great way to care for their hair and scalp while being eco-friendly.

However, like any other beauty product, shampoo bars aren’t one size fits all. That’s why we’ve put together some tips on how to choose the right shampoo bar for your hair type and lifestyle.

#1 Know Your Hair Type

Before buying any shampoo, you need to determine what hair type you have.

Just like traditional shampoos, shampoo bars are created for specific hair types.

If you have oily hair, look for bars with ingredients like tea tree oil and rosemary.

If you have dry hair, find a shampoo bar with argan or coconut oil.

If you have curly hair, look for bars that contain shea butter or avocado oil.

You’ll also find bars made for color-treated hair, fine hair, and even dandruff.

#2 Check the Ingredients

One of the benefits of using a shampoo bar is that it typically contains fewer ingredients than a liquid shampoo.

However, that doesn’t mean that all shampoo bars are created equally.

Check the ingredients carefully to ensure that there are no harsh chemicals or irritants.

Avoid bars with ingredients like SLS (sodium lauryl sulfate), parabens, and synthetic fragrances.

Instead, go for bars made with natural, plant-based ingredients.

#3 Consider Your Lifestyle

Your lifestyle can also play a part in choosing the right shampoo bar.

If you spend a lot of time outdoors, you might want to try a bar with neem oil to repel insects.

If you’re a frequent swimmer, choose a bar that removes chlorine buildup.

If you’re on the go, try a multi-purpose bar that works as a shampoo and body wash.

#4 Trial and Error

It’s important to remember that not every shampoo bar will work for everyone.

It may take some trial and error to find the right one for you.

If you’ve never used a shampoo bar before, start with a sample size or travel size bar.

Use it for a few washes to see if it works for you.

If not, try another shampoo bar until you find the best one for your hair type and lifestyle.

#5 Storage

The last thing to consider when choosing a shampoo bar is how you will store it.

Proper storage will help prolong the life of your bar and prevent it from getting mushy and melting away.

Store your bar on a soap dish with drain holes, or use a shampoo bar tin or travel container for on-the-go. Keep your bar dry in between uses to keep it firm and solid.

Is a shampoo bar good for colored hair?

Yes, shampoo bars are very good for colored hair actually!

These all-natural products are great for all hair types and colors because they don’t contain any of the harsh chemicals that can damage your color or dry out your locks.

They’re also eco-friendly and last much longer than liquid shampoos.

However, there is one catch: it’s important to find a one with high-quality ingredients in order to prevent build-up on your scalp which can lead to dandruff and scalp issues!

We get asked a lot of questions about Lush shampoo bars which come in a variety of gorgeous scents and colors.

Unfortunately, they also contain sulphates which strip your color. So we won’t be featuring them here!

How do I use a shampoo bar?

Shampoo bars are easy to use! Just follow our quick guide below. You read more in How to use a shampoo bar for colored hair.

Do I need to condition my hair too?

You’ll still need to condition your hair after you use the shampoo bar to keep your hair supple and your color locked in.

Some people find that they can be quite drying until your hair gets used to them, so it’s important to give it some extra love.

Check out our top recommended conditioners for colored hair to find the one for you.

Once a week, use a deep conditioner to restore any lost moisture and bounce.

How do you store shampoo bars in the shower?

We all know the struggle of trying to hold onto a slippery wet block in an awkward position with one hand while you’re lathering your hair with the other. It’s not easy!

It may be solid, but it’s not going to stay in one piece forever.

It will eventually start to separate and you’ll need to mix up your bar with some oil or conditioner before using it again.

The question is: where do you keep it?

When there are so many bottles of shampoo on the floor, can’t we just have a place for our soap?

Luckily, there’s a way to make it easier on yourself. We recommend a good old soap dish like this one from Amazon to protect your bar in between washes.

Ones with a lid make them handy to carry around too and take them with you easily when you travel.

Can I make my own shampoo bars?

If you feel inclined, you can also make them yourself! Here’s a great video tutorial that shows you just how to DIY shampoo bars step-by-step.


Parting words.

So, there you have it! If you’re looking for a cruelty-free, natural hair care routine to nourish your locks and protect the planet, why not try these out?

With so many different products on offer now it’s never been easier. Regardless of your hair type or preference for natural products, we’ve found the best ones for colored hair.

We hope this post has helped to answer some of your questions and given you a better understanding on how these bars can nourish your locks without stripping color.

Now go get yourself some natural goodness and start feeling good about what’s in store for your gorgeous mane!
