What is a shampoo bar?

Slowly but surely, an exciting new revolution in coloured hair care is creeping up on us. They’re firm, they’re pretty, they smell out of this world. AND it’s official, they can outlive your favourite coloured hair shampoos by three bottles!

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

They contain all-natural ingredients with no nasty chemicals or additives like sulphates that can dry your hair and damage your follicles. Their blend of natural ingredients are high quality, luxurious and 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.

If you feel inclined, you can also make them yourself!

Why should I use a shampoo bar?

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

Pros

  • 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.

Cons

  • 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.

Is a shampoo bar good for coloured hair?

Yes, actually. These all-natural products are great for all hair types and colours because they don’t contain any of the harsh chemicals that can damage your colour 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 colours. Unfortunately, they also contain sulphates which strip your colour. So we won’t be featuring them here!

Best for: Much-needed moisture

J.R Liggetts offering is a charmingly old fashioned looking bar that resembles a pack of butter! It smells good enough to eat too!

We found this one hard to get the quantity right so as not to leave a residue, but if you nail it, the results are fab. This bar is infused with argan oil which our stressed coloured tresses loved and left them feeling superbly soft and moisturised. There’s also a handy mini version for travelling too.


#1 Faith in Nature Natural Dragon Fruit Shampoo Bar.

q? encoding=UTF8&ASIN=B089WM2H5Q&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBfaith in nature

  • SLS, SLES, Paraben Free
  • Cruelty Free, No animal testing
  • Works well in hard water
  • They also condition your hair.

Reviewers say:

“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 Soul & Soap! 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!”

We say:

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.

It lathers really well compared to other bars and our hair felt soft afterwards and not at all waxy. The reviews all talk it lasting really well too. What’s not to love?

Best for: Long lasting bar.

Reviewers say:

“After just one use of Ethique’s Frizz Wrangler, my mind and hair is blown. I will never use another brand now!! You know the feeling of having a fresh hair cut? Your hair is light and healthy feeling? That is the only way I can describe how my hair feels after using this bar. Love it!”

“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.”

We say:

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 coloured hair.

It smells amazing and the coconutty goodness felt super luxurious on our hair. It washed out great with no residue and left our hair feeling super soft and our scalp feeling moisturised. This is the best one for softness.

“I adore this! It’s lasting really well. I bought ‘Bounty Hunter’ as I have highlighted hair, it leaves it super clean and shiny.”

“Smells so great and it’s really easy to use. Cleans my coloured hair without stripping the colour.”

We say:

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.

Best for: Clean, shiny glossy locks.

“If you have dry hair or if you colour your hair or if you are out in the sun a lot, this is an amazing product. Nothing I have bought in a plastic bottle no matter what the cost has compared to this!”

We say:

J.R Liggetts offering is a charmingly old fashioned looking bar that resembles a pack of butter! It smells good enough to eat too!

We found this one hard to get the quantity right so as not to leave a residue, but if you nail it, the results are fab.

Reviewers say:

“Has a really good lather and smells delicious. This is one of the better ones but still leaves my hair a little waxy.”

“My hairdresser noticed that my hair is in fabulous condition. Love this shampoo.”

“This is a completely natural, vegan product that comes wrapped in cool looking tissue paper, so you really can pat yourself on the back for using it.

We say:

PureChimp’s delicious smelling bar is like a solid smoothie packed with coconut oil, olive oil, avocado oil, banana and even beer! The beer added shine and bounce to our hair.

They say your hair may need 2-3 weeks to eliminate the chemical residue left by previous shampoos and that’s true. Our hair did feel a little coated afterwards but less dry than before. Our sensitive scalp from all the coloured hair treatments felt soothed and calm.

(Pure Chimp’s incredible Matcha Green Tea is also worth adding to your basket!)

Best for: Sensitive skin.

#6 Clovelly Soap Co Handmade Natural Shampoo Soap Bar, Eucalyptus Mint & Lemon.

q? encoding=UTF8&ASIN=B07FJPF5BP&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBclovelly bar for shampoo

They say:

  • Gentle non drying soap bar with added castor oil.
  • For normal – dry hair and scalp.
  • Washing your Hair with our bars can help you reduce your plastic consumption.
  • You may benefit from a vinegar rinse after each wash or your standard conditioners.

Reviewers say:

“Love the packaging, love the smell, love the shop! Love everything about this new bar and I’ll never switch to anything else now.”

“You have to push through the first few washes until your hair adjusts but I’m so glad that I did! It really lathers well and my husband keeps commenting on the smell. It’s so lovely!”

“This gave me a sticky residue on my hair at first but I loved the smell so kept on using it. After a while your hair becomes fluffier and starts to look and feel amazing. Well worth with it.”

We say:

This gorgeous, wholesome brand comes from Devon and they are real artisan masters of all things soap. We found some of the fragrances a little too ‘granny’ but this one smells lovely and fresh, with notes of citrus and mint.

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. We didn’t need to but we used this on hair that wasn’t too dry or damaged. This is the best foamer of the bunch so is great for hard water areas. It’s bigger than other bars too so a little goes a long way and you get more to boot.

Best for: Hard water and great value.


Do I need to condition my hair too?

You’ll still need to condition your hair after you use the shampoo to keep your hair supple and your colour 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 coloured 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.


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 coloured 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 colour.

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