How To Choose The Best Shampoo Bars In The UK 2021 

Make Sure It’s A Real Shampoo Bar

Are you sure that all the products labelled “shampoo bar” on the market are really shampoo bars? The answer is no!

Because it’s difficult for most of us to distinguish between the soap bar and shampoo bar, several manufacturers have swapped these two products’ concepts. They use the same ingredients and process  when making soap bars to make so-called “shampoo bars,” and even label them so. Without being cautious, you might fall prey to these soap bars in disguise.

Also, some of the shampoo bars even contain substances like parabens, surfactants and silicones. They are harmful chemicals and can cause hormonal disorders in the body.

How to choose the Best Shampoo Bars

The best way is to buy products from reputable brands. Or if not, double-check the product packaging to get necessary information about them.

Make sure if there is enough information on the package about the manufacturer. Are the ingredients in the shampoo bar mentioned? Is the print quality clear, easy to grasp information printed on it? Reputable manufacturers will often try to make it as easy as possible for users to get information about their products.

Determine The Hair Types

This step is extremely important and is a must-do. Suppose you can’t identify your type of hair and choose the wrong shampoo. Your hair condition won’t improve, and to make matters worse, it might even exacerbate.

Dry hair with itchy scalp: The main cause of dry hair is the scalp’s reduced ability to secrete sebum. This causes the loss of moisture, which leads your hair to become less fluffy, drier and more prone to breakage.

So, you should use shampoo bars that are high in moisturisers like shea butter or coconut oil. Besides, a shampoo bar with aloe vera is recommended for dry hair as it’s benign to hair and scalp as well as sensitive skin.

Oily hair: You have oily hair because the sebaceous glands are overactive; they make it sticky and difficult for your hair to fold.

However, you shouldn’t use products labelled “drying” shampoo as these can remove necessary oil and moisturiser and ultimately make your hair very dry.

So, shampoo bars that contain natural saponins or extracted from citrus oil are suggested. These substances will help cleanse the hair and scalp without losing all the necessary moisture.

Dandruff hair: This is a rather common problem. Most anti-dandruff shampoos will easily make your hair drier. Therefore, we recommend you to choose natural shampoo bars that contain ingredients like neem, tea tree oil, apple cider vinegar, and herbs to eliminate dandruff while retaining essential moisture.

Check The Ingredient

In shampoo bars, natural ingredients such as oils, avocados, herbs, aromatherapy from fruits or flowers are common. You only need to make sure that you are not allergic to any of them.

Besides, some chemicals can be harmful to your health, from which you should absolutely steer clear. For example, they can include surfactants, parabens, silicone and some dimethicone-based substances.

Choose The Scent

This isn’t all too important, but obviously, it is a wonderful feeling when you smell your favourite scent in your hair. The fragrance also contributes to  calming down your mood and relaxing you.


What Are The Differences Between Shampoo Bars And Soap Bars?

Many people think that soap bars and shampoo bars are exactly the same. However, they are two totally different types of products.

Some people might know they are two different kinds of soaps but still, can’t tell them apart. By simply reading the packaging, you will be able to do so with ease.

The ingredients that make solid shampoos and shampoo bars seem similar at the first glance, as they are mostly butter and oils. However, soap bars are generally not recommended for use on hair.

The reason lies in soap bars’ ingredients:  soap embryos with the main ingredient of sodium hydroxide. This chemical ingredient has a displeasing PH level for your hair and scalp. Simply put, shampoo bars are similar to liquid shampoo but condensed. Therefore, their PH will be in equilibrium, at about 6 to 7. This is different from soap bars, which have a PH level of 7+.

In addition, solid shampoo is specially formulated through a superfatting process to maximise the benefits of the oils added to shampoo. Thus, the shampoo bar will gently keep your hair clean without feeling too sticky or too dry.

How To Use The Shampoo Bar In The Right Way?

The important thing you should pay attention to when using the shampoo bar is to create a lot of foam. And of course, not everyone can do this.

Before washing, you should comb out your hair to limit tangles and make it easier for your hair to fold after washing. Then wet your hair like you normally do when using liquid shampoo.

To apply shampoo bars, you can choose one of two ways: lather it on your hands first or directly on your hair. With the first method, wet your hands, then rub the bar to create a lot of foam and lastly, apply. The other way is to use solid shampoo directly on hair to create foam.

Whichever method you choose, keep in mind that you should start applying the shampoo from the roots, then stroke to the ends of your hair. This way is believed to generate better effects.

How Often Should I Use A Shampoo Bar To Wash My Hair?

There isn’t an absolute answer to this question; it all depends on your needs and hair condition. If your hair is too sticky, of course, you need to wash it as soon as possible. On the contrary, if you feel like it’s still fine, don’t bother!

However, you should still wash your hair about one to three times a week to make sure your hair is in good condition. Regular washing will minimise the harmful effects of the environment on the hair, such as smoke and dust.

If I Have Coloured Hair, Can I Use A Shampoo Bar ?

The answer is possible!

As we all know, solid shampoo is composed of natural ingredients that don’t harm the hair. At the same time, the PH level of these haircare products is balanced, not containing alkaline or bleach that affects your hair colour.


There you go; we provided you with all the necessary information about the top 10 best shampoo bars in the UK 2021. We hope that our article will be helpful for you in choosing and reaching  your buying decision.

To sum up, we highly recommend Faith in Nature shampoo bar as the best option. Obviously, being high-quality and budget-friendly, this product is worth your try!
