How I discovered shampoo bars: I invented them!
When I'm back home in the USA, I use amazing shampoos and conditioners… ones that are sulfate free, made with organic ingredients, and are blessed by a Rabbi. When I travel though, which is about eleven months out of the year, I'm left using cheap shampoos that I pick up from local pharmacies or are provided by the hotel.
Believe it or not, the selection of hair products available in other countries is not always as great as what's available in the USA – and quality shampoos cost a lot of money overseas! For example, I can pick up a bottle of one of my favorite brands of organic shampoo and conditioner at Dollar General in USA for about $5-7/each, but that same bottle in Colombia costs close to $30!
Aside from price and availability, I'm hesitant to buy expensive shampoo overseas because I usually end up leaving behind half filled shampoo bottles wherever I go since I can't travel on airplanes with them. (Better than leaving behind half empty ones though, am I right?) And buying travel sized shampoo bottles is economically stupid – it's cheaper to buy a big bottle and leave most of it behind than for me to buy the small sizes.
Last week when I was going through airport security, I saw some poor soul get their shampoo bottle thrown away, and I had an idea. What if I invented a non-liquid shampoo? That way I could travel through airports with my favorite brand of hair product.
Well it turns out that non-liquid shampoos already exist in bar form, so I decided to do some research to see what's out there. During my research, I only looked for products with comparable ingredient stories to the shampoo and conditioner that I use back home, because I don't want to trade the cheap liquid shampoo I'm using now when I travel for an equally shitty bar shampoo. That sort of defeats the purpose of why I'd be interested in traveling with shampoo bars. I'd only be interested in buying and traveling with shampoo bars if it meant that I could use better quality products again.
This post is a compilation of my research about bar shampoo bars, however my list of Best Sulfate Free Shampoo bars is not exhaustive. I'm interested in finding the BEST sulfate free shampoo bars on the market, so if you know of a brand that I missed please leave the link in the comments.
What's the chemical difference between bar soap and bar shampoo? Can't I just use the same bar for my hair and body?
Lindsey from Chagrin Valley Soap & Salve explains in a blog post that the difference between bar soap and shampoo is, “the proportions of the base oils and butters, a number of extra oils or superfatting, and the way in which I use infused oils, botanicals and essential oils in a shampoo bar recipe is different.”
She goes on to say, “Shampoo bars usually have more castor oil. The only oil containing ricinoleic fatty acid, castor is a great hair care oil, a fabulous humectant, and contributes to the fluffy, bubbly lather that people seem to like in shampoo bars.”
Since the shampoo bars have less extra oil, they may not be as moisturizing as soaps, but they'd certainly get the job done. A high quality shampoo bar made from natural ingredients is probably better for your skin than a low quality high perfumiated chemically infused bar of soap from a hotel.
Benefits of shampoo bars versus liquid shampoo
Here are what I learned to be the environmental, financial, and travel pros of using shampoo bars.
- They last longer. Some shampoo bars advertise that they will last 60-80 uses or about 3x as long as a bottle of shampoo.
- They are Sodium Lauryl Sulfate free. This can't be taken for granted as a blanket statement though, because not all shampoo bars are SLS free. However, since shampoo bars are still a niche product, for the most part, the brands that make them are conscious of the ingredients they use, and most are sulfate free.
- They don't use plastic packaging. Plus one for the environment! Most shampoo bars come packaged in biodegradable paper or in no package at all if sold in a store. This helps decrease the amount of plastic waste typically associated with hair products.
- They can be used for both hair and body. Certainly using one bar for both purposes has its disadvantages, but technically speaking, a shampoo bar can handle both jobs which will save you some space in your toiletry bag.
- They're lightweight. Speaking of saving space, shampoo bars are lightweight and compact. One bar of soap can replace the equivalent of 3 shampoo bottles which can be a perk because every ounce adds up when traveling.
- They are less prone to spill all over your bag. Unlike a bottle of liquid, shampoo bars won't accidentally break and leak all over your bag.
- You can use every last bit. Alternatively, sometimes it's hard to get all the liquid out of a shampoo bottle, but that's not an issue with shampoo bars which you can use down to the last flake.
Aside from the benefits above, some people say that shampoo bars do a better job of cleaning their hair. But to be fair, many statements like this came from people who switched from using shitty liquid shampoo to shampoo bars – so their results may have partially been from switching to a shampoo without chemicals and sulfates in general. What do you think?
Cons of shampoo bars
It's not all fun and games though. I've read a few negative sides to switching to shampoo bars like:
- Waiting for them to dry is a bitch. Some travelers have said that if they don't wait for their soap to completely dry before packing it away, they come back to a squishy mess. My friend Suzanna solves this problem by shaving off a few pieces and only bringing what she needs to use into the shower with her.
- It doesn't get your hair as clean. Other travelers have said that shampoo bars don't lather as much, and therefore they didn't feel like their hair got as clean. These stories are anecdotal though because maybe they weren't using enough, applying it right, or using a quality brand of shampoo bar. Remember, not all shampoo bars are created equal.
- The shelf life of a shampoo bar is shorter, kind of. Although the soap itself won't go bad, sometimes the fragrance of the soap disappears with time if you store it for too long because most shampoo bars use essential oils for fragrance. Also, in time, the water evaporates from the bar causing it to dry up and harden. However, most of the shampoo bars I profile in this post indicate that their shelf life is at least 1 year.
Aside from those three things, I couldn't find too many cons to shampoo bars. After my research, I'm thinking that your success with shampoo bars has a lot to do with which brand you choose. This leads us to the next sections…
Types of Bar Shampoos
There are three broad categories of shampoo bars, although some will overlap categories.
- Cold-pressed shampoo bars are typically made by home crafters and natural product companies. They are often full of natural oils to help condition your hair and are usually free of SLS.
- Glycerin-based shampoo bars are oftentimes more gentle and pH balanced, but some people say they don't lather as well.
- Solid surfactant shampoo bars lather the best and are more pH balanced but contain SLS which can be an irritant for some people.
In this article, I am exclusively profiling shampoo bar brands that are SLS-free, so they will fall into the first two categories above.
What are Sodium Lauryl Sulfates (SLS) anyway?
If you aren't sure what I'm talking about when I say SLS, I'm referring to Sodium Lauryl Sulfate which is an inexpensive and commonly used chemical found in many household shampoos, soaps, toothpastes, and detergents. SLS is a detergent and surfactant, and its primary purpose is to break surface tension and separate molecules in order to allow for a deeper interaction between the soap and your hair or skin. It's essentially the ingredient in most soaps that create the lather and it's widely used because it's so cheap.
The downsides of SLS is that it's a common skin irritant, is rumored (but not proven) to cause cancer, and is terrible for the environment. In fact, it's such a common irritant that it's sold to companies specifically for that purpose when testing products used to heal skin conditions. That's why so many people look for sulfate free shampoos, conditioners, and soap. I read an article from Lush about how SLS aren't so bad and you shouldn't stress about them (because Lush uses them in their bar shampoos), and HOLY SHIT you should read the comments! But to save you the time, I'll summarize: &$%# you Lush! SLS are the devil and they made my kid itch. However, jokes aside, sulfates aren't great for you and there are plenty of natural alternatives that provide the lather effect for soap. That's why I didn't include LUSH on the list today or any other brand which uses SLS in their shampoo bars.

Which is the best brand of shampoo bar?
Now that you've seen my list of Top 10 Sulfate Free Shampoo Bar brands, it's your turn to tell me – what's YOUR favorite shampoo bar brand and why? Drop a comment below with your reviews and recommendations.
What about conditioner bars?
Many, but not all, of the brands above offer conditioner bars to complement their shampoo bars. The reasons I did not create a separate list of conditioner bars are because 1) there would be a lot of overlap between the two lists, and 2) many folks who use shampoo bars have said that the natural oils found in these bars work to condition their hair and that they stopped using a separate conditioner. However, if there's a brand of conditioner bar you'd like to recommend, please do so in the comments as well. Happy travels everyone!
