If you are looking to ditch conventional beauty products, hair care products should be among the first clean beauty products you switch over to, as they are generally full of ingredients that are not safe for you or the environment.

As consumers, our actions impact the planet for better or worse. Our daily choices can help or harm the environment in so many ways. One small but important step you can implement right now and without too much time or expense is to switch out your conventional shampoo and conditioners for plastic-free, sulfate-free zero waste shampoo and conditioner bars.

While most of us want our hair to be shiny, soft to the touch, and untangled, we often overlook the connection between the ingredients in these products, the health of our hair, and the well-being of our planet.

The major problem with conventional shampoos and conditioners is that they contain a lot of harmful ingredients that are bad for us, such as preservatives, surfactants, synthetic fragrances, and emulsifiers. Plus, they contribute to a lot of plastic waste that harms our environment.

If you are looking to get away from all this, solid eco-friendly shampoo and conditioner bars are the non-toxic answer.

Benefits of Switching to Zero-Waste Shampoo And Conditioner Bars

 There are plenty of reasons why people love their solid shampoo and conditioner soaps. Here are just a few.

  • The majority of shampoo and conditioner bars do not require traditional packaging and so they do not generate waste and are a more sustainable option. They are considered a zero-waste product because you can use up the entire bar without throwing anything out. If it does come with packaging, it is either recyclable or biodegradable.
  • Solid shampoo and conditioner bars are travel-friendly. No more hassles with bulky bottles that won’t fit snugly into your travel bag or any ruined items because of spills. With a solid bar, it’s easy to pack and dries out for no residue or spillage. This also means they are great for the gym!
  • There are usually no harmful or questionable ingredients This is better for your hair and scalp, better for the environment, and better for your overall health. No more dry hair or stripping your hair of its natural oils.

SIDEBAR: Do check the full ingredient list to make sure there are no ingredients in the formulation that you are trying to avoid. While most of the solid bars I looked at were clean, you still want to do your due diligence.

  • If you make your own shampoo and conditioner bars at home, you can adjust the ingredients to fit your preferences. This gives you full control over the aroma, the essential oils used, and the ingredients used for making it lather up. You know exactly what goes into your bar, so you know exactly what goes into your hair.
  • They are non-toxic, cruelty-free, extension-safe, vegan-friendly, and can last for many, many washes. Plus, they double as a soap bar when you don’t have access to regular body soap or shaving cream.

 Is It Worth Switching: Do They Work?

 Anyone can easily integrate an eco-friendly shampoo and conditioner bar into their clean, beauty routine, but the question is, do the bars work? If you have the patience to deal with the transition period from liquid to bar and can get a grapple on the learning curve of how much lather you need, then the answer is yes.

Yes, shampoo and conditioner bars definitely work but you need to find the right one for you and you need to stick with it for more than a week or two.

Can They Replace Traditional Shampoos And Conditioners?

 Yes, they can.

 A high-quality, all-natural shampoo or condition bar can completely replace your traditional liquid shampoo and conditioner options.  Soap bars offer the same cleansing benefits but cut out harmful ingredients and cut down on plastic use.

Just keep in mind that not all shampoo and conditioner bars are made equal, so research the ingredients before buying.

Common Issues With Shampoo And Condition Bars That Pop Up

 When making the transition from traditional, commercial-grade liquid shampoos and conditioners to solid, natural shampoo and conditioner bars, there are going to be some issues that pop up.

  1. Dealing With Hard Water. The transition from liquid soap to a solid bar is made more difficult if you live in a home that has hard water. Hard water is simply water that has a high mineral content, most notably calcium and magnesium. When showering or bathing with hard water, the soap you use will react to the minerals in the water, resulting in a soap film and insoluble deposits on the hair. To get around this, you can purchase an inexpensive shower head filter to remove the excess minerals from the water or you can use distilled water to rinse your hair. Another way to deal with this is to rinse your hair with lemon juice, vinegar, or a weak acid rinse.  Here is a great guide to understanding how hard water impacts your hair.
  1. Storing Your Solid Bar. The main thing with storing your solid shampoo bar is to not place it in a wet environment where it can’t dry out. Doing this will turn it to mush and you won’t get very many washes out of it. Instead, let it dry out by storing it in a cool place with airflow. Ideally, placing it in a mesh bag or soap holder with a perforated bottom is a good idea.

SIDEBAR: placing your bar in the sun will not affect the performance but it may change the natural color or cause the fragrance to fade.

  1. Dealing With Residue And Buildup. When you first switch from liquid shampoo to a natural bar, you’re going to experience a transition phase where your hair is going to be greasy, dull, and feel waxy. You may also experience more residue and buildup being left on your hair as your hair learns how to rebalance its natural oil production.

How to deal with this?

  • Use a mix bristle brush to help pull any excess oils and previous residue from liquid soaps off your scalp. While it will deposit them into your hair, you can simply rinse them out.
  • Rinse your hair out in sections to make sure that you are getting all of the soap out. This works really well for those who have hard water or super thick hair.
  • Only use the lathered portion on your roots. This will help prevent your hair from holding onto the soap.
  • Consider using an apple cider vinegar rinse to address residual buildup. This buildup comes from the residual silicones from liquid shampoo and conditioners. It also helps restore your natural sheen and reduces frizz and tangles.

How To Find a Zero Waste Shampoo And Conditioner Bar That Works Great For You?

With so many shampoo and conditioner bar choices out there, it’s hard to know which type of bar will work best for you.  This is especially true if you keep coming across brands that have bars for all types of hair textures. To help you narrow down a bar that’s going to nourish and revitalize your hair, here are the types to look out for.

  1. Cold-pressed will be chock-full of natural oils which can help condition your hair and they will be free from sodium lauryl sulfate, but they can cause a buildup. This tends to require a weak acid rinse.
  2. Glycerin-based will be gentle on the hair and pH balanced but they will not lather as well and may not be as clarifying as other types.
  3. Solid surfactant-based will lather extremely well and have a higher pH level but may be too clarifying for some types of hair.

 What to Do if Your Shampoo Bar is Not Working For You?

 Experiment! The thing with solid shampoo and conditioner bars is there isn’t a perfect one out there and you can only find one that works by using trial and error. The best thing you can do if your bar isn’t working for you is to look at the ingredient list and make sure that

A. Doesn’t contain any SLS surfactants unless you are using it in conjunction with a conditioner.

B. Doesn’t contain any palm-derived glycerin or sulfates.

C. Doesn’t contain sodium hydroxide as this has a pH level that may be too unfriendly (read strong) for some hair types.

Tips for Using Your New Solid Shampoo And Conditioner Bars

  • Always dry brush your hair first
  • Get your hair completely soaked. The wetter you can get it, the better
  • Try different application techniques:
    a. Use the bar directly on your hair in sections from scalp to tip
    b. Lather it in your hands if you have long or thick hair
  • Rinse, rinse, rinse, and rinse some more
  • If you have oily hair, skip the scalp area when using a conditioning bar
  • Leave conditioner bars in for at least 2 minutes
  • Consider lightly using a comb to rinse out conditioner bars
  • Towel dry and do not blow dry right away
  • Use an apple cider vinegar rinse if the transition period is giving you trouble
