9 Best Shampoo Bars for Fine Hair

best shampoo bar for fine hair

Having thin hair can be difficult to manage and my friend Susan really struggles to add any volume whatsoever. With natural shampoo bars becoming more popular than ever I thought I’d investigate which shampoo bars are the best for people with thin or fine hair.

The best shampoo bars for fine hair are those that help to increase volume. Natural shampoo bars are particularly good for increasing volume as they are enriched with plant-based oils like argan or jojoba oil, which not only add volume but provide essential nourishment without weighing down hair.

So in this article, I thought I’d bring Susan along for the ride. When testing the shampoo bars I would get a much clearer result if she tried the products herself.

Luckily she accepted my offer and so together we explored why shampoo bars are important for people with thin hair and tested the top bars, sharing our personal experience, research and experiments.

Fancy skipping our crazy experiments, no problem.

Here are our top two choices when it comes to the best shampoo bars for fine hair.

What are Shampoo Bars?

Shampoo bars are a revolutionary alternative to traditional liquid shampoos, designed to cleanse and nourish the hair without the need for plastic packaging.

These solid bars contain concentrated, natural ingredients that eliminate the need for harmful additives often found in liquid shampoos.

Not only are they eco-friendly due to reduced packaging waste, but one of my favourite benefits, they also offer a convenient and travel-friendly solution for those constantly on the go.

Why are Shampoo Bars Better?

There is absolutely no doubt that shampoo bars have gained popularity in the last decade.

The original benefits were mainly around being eco-friendly but now their advantages extend way beyond their environmental friendliness.

Here’s a couple of the environmental advantages:

  • The concentrated formula means less water content and, consequently, a smaller ecological footprint.
  • Shampoo bars often come in minimalistic, zero-waste and even compostable packaging

Other non-environmental benefits include:

  • Many shampoo bars are formulated with natural ingredients, omitting harsh chemicals that can strip the hair of its natural oils.
  • The absence of liquid content means they are more potent and long-lasting, making them a cost-effective choice in the long run.

When Susan and I chatted this over we came up with lots of benefits for using shampoo bars but that will have to wait for another article.

Let’s move on to how shampoo bars actually help people with thin hair.

How Can Shampoo Bars Help People with Thin Hair?

Susan explains:

Having fine hair comes with its own set of challenges, from lacking volume to struggling with oiliness.

But what we’ve found in our own research and experiments is that shampoo bars, with their concentrated and natural formulations, can be a game-changer for individuals with thin hair.

Firstly, the absence of heavy synthetic ingredients helps prevent product buildup, ensuring that hair remains light and airy.

Many shampoo bars are enriched with plant-based oils like argan or jojoba oil, which provide essential nourishment without weighing the hair down.

This not only adds volume that people crave but also promotes overall hair health.

As well as this we found that the gentle nature of shampoo bars ensures that the scalp isn’t over-stripped of its natural oils.

This is crucial for those with fine hair, as an imbalanced scalp can lead to increased oil production, exacerbating the issue of flat, lifeless hair.

How Were the Shampoo Bars in This Article Selected?

Choosing the right shampoo bars for fine hair required a combination of research, expert advice, and hands-on testing.

Susan and I scoured the market for products that prioritized natural ingredients, avoided harsh chemicals, and had a reputation for adding volume and thickness to fine hair.

We considered customer reviews and expert recommendations, giving preference to brands committed to sustainability and ethical practices.

Shampoo bars that excelled in addressing the specific needs of thin hair, such as providing volume, reducing oiliness, and promoting overall hair health, made it to our shortlist.

Susan’s talked to her hairdresser who played a pivotal role in our selection process.

Her insights into the unique challenges faced by individuals with fine hair ensured that our choices were not only effective but also tailored to the specific requirements of thin locks.

How Were the Shampoo Bars in This Article Tested?

Putting our selected shampoo bars to the test was a meticulous process that involved multiple factors.

Susan and I considered how each bar lathered, its fragrance, ease of application, and for Susan, most importantly, its impact on the texture and volume of her fine hair.

We tested each shampoo bar for an extended period, allowing for a fair assessment of its long-term effects.

Regular use helped us gauge how well the product controlled oiliness, and added volume as well as contributing to the overall health of our hair.

Susan’s keen eye for detail and her ability to notice subtle changes in her hair texture and appearance were invaluable during this testing phase.

So here they are, the best two shampoo bars for fine hair.

Best Shampoo Bar for Fine Hair

Winner: Ethique Sweet & Spicy Volumizing Solid Shampoo

Our Rating: 9.8/10

Ethique Sweet & Spicy - Volumizing Solid Shampoo Bar for Fine, Flat, Limp Hair - Vegan, Eco-Friendly, Plastic-Free, Cruelty-Free, 3.88 oz (Pack of 1)

Here are Susan’s thoughts on Ethique’s Sweet & Spicy Volumizing Solid Shampoo.

As someone constantly on the quest for the perfect shampoo, Ethique’s Sweet & Spicy Volumizing Solid Shampoo is a game-changer for both my hair and my commitment to sustainability.

After using this shampoo bar for a considerable time, I can confidently say it lives up to its promises and has become my everyday go-to hair care solution.

First and foremost, this shampoo excels in adding body to the hair but also leaves my hair looking healthier and more vibrant.

After just a few weeks I could see a significant increase in my hair volume after using the product which is exactly what Jenna and I were looking for.

In addition to adding volume, this shampoo is also effective for oily hair. Although not particularly an issue for me many user reviews report only good things in this area with one user with a teenage daughter battling super oily hair expressing their struggles with various clarifying shampoos until they found Ethique.

Another great benefit I found with this shampoo bar is that it significantly extended the time between washes, allowing me to enjoy three days of refreshed and non-greasy hair.

While some users in the reviews described the scent as peculiar, fragrance is of course subjective, and for me, the results mattered more than the initial aroma which is actually fine.

The unique blend may not be sweet or spicy as the name suggests, but it is subtle and dissipates after rinsing, leaving only clean, fresh hair behind.

What sets Ethique apart is its commitment to sustainability, and this is reflected in the longevity of its shampoo bars – they last a long time.

This, coupled with the minimal waste packaging, aligns perfectly with my efforts to reduce plastic consumption.

It’s quite well known that there is a learning curve to using bar shampoos, however, I found the Ethique Sweet & Spicy Solid Shampoo is easy to use, creating a satisfying lather that thoroughly cleansed my hair.

In conclusion, Ethique Sweet & Spicy Volumizing Solid Shampoo has become my everyday choice for clean, voluminous hair with the added benefit of reducing plastic waste.

The shampoo’s performance, coupled with its eco-friendly packaging and longevity, makes it a standout product.

I highly recommend it to those looking for an effective solution to combat fine hair.

So there you have it – a very worthy winner!

Our Rating: 9.6/10

HIBAR Volumize Shampoo Bar: Dry Shampoo for Fine Hair - Hair Growth Stimulator with Rice Water, Gently Cleanses, 100% Vegan, Plastic-Free, Travel-Friendly

Susan found the HiBAR Volumize Bar Shampoo for Fine Hair another great product exceeding her expectations in more ways than one.

This Volumize variant, with its ability to provide volume without weighing down the hair, has been a game-changer for her. It has given her somewhat thinned hair the lift it needed, bringing back the volume that she has struggled to achieve with other liquid shampoos.

Susan’s hair care routine typically involves washing every three days and so the shampoo bar has lasted a long time.

She also mentioned that the volumize bar left her hair feeling clean, bouncy, and noticeably frizz-free.

In terms of scent, the light fragrance added a pleasant touch without being overpowering.

One of her initial concerns was whether the shampoo bar would effectively lather, as we had encountered issues with other brands but the bar produced a lovely rich lather, proving that sustainable choices don’t mean a compromise on performance.

One reviewer who battled with mild eczema praises the shampoo for being the only one that doesn’t exacerbate scalp dryness. Having experienced similar challenges myself with ‘sensitive scalp’ shampoos, I totally agree.

Naturally, the absence of plastic in the packaging is a benefit that aligns with our commitment to reducing single-use plastic waste.

In conclusion, the HiBAR Volumize Bar Shampoo has exceptional performance in adding volume to Susan’s fine hair, combined with the environmental benefits of plastic reduction, making it a standout product for us both.

We found the HiBAR Volumize Bar Shampoo stands out as a comparable product to other premium shampoos, and we really appreciate the brand’s commitment to sustainability.

All in all, a very worthy runner-up.
