They are environmentally friendly
This is by far the biggest advantage we have in mind when switching to solid shampoos and conditioners. Since they are not packaged in plastic, they are much more environmentally friendly compared to liquid shampoos.
It is estimated that with 8 billion people on earth, this can mean 16 billion plastic packages per year (calculated per average user). So, we could save 690,000 pieces of plastic packaging every minute. However, if we consider that almost half of this packaging ends up in landfills and later in the sea, the environmental contribution from using solid shampoos is enormous.
A single plastic package can decompose for more than 450 years. Solid shampoos significantly reduce the amount of plastic waste. A Zero Waste solid shampoo can be an excellent way to reduce your carbon footprint.
They are free of harmful substances
4kidsandus solid shampoos do not contain parabens, artificial colors, artificial fragrances, emulsifiers, water, harmful preservatives, or other chemicals. Our shampoos are also suitable for vegans as they do not contain any animal ingredients.
They are a feast for the eyes in your bathroom
Have you ever seen plastic packaging in a good interior design magazine? Of course not. Solid shampoos help create a minimalist aesthetic in your bathroom, which will look elegant, minimalist, and modern.

They are sustainable
One bar of solid shampoo can last up to 80 hair washes, which is equivalent to 3 bottles of 250 ml liquid shampoo! Because solid shampoos are more concentrated than traditional shampoos and conditioners, their application is much smaller. If you look at the plastic packaging of shampoo or conditioner in the shower, the first ingredient you will see is water. This explains how many more active ingredients are hidden in the shampoo bar itself compared to liquid shampoo. This also means they are more economical. A liquid shampoo with such a rich composition as 1 solid shampoo would cost significantly more than 12 EUR. Cheap shampoos, on the other hand, contain very little or no active ingredients. In other words, if you buy 1 liter of shampoo for 4 EUR, you have bought very expensive water with a cheap foaming agent.
They are much more natural
Many traditional shampoos contain preservatives and chemicals that strip hair of its natural oils and leave the scalp dry. Solid shampoos contain many more natural ingredients that are good for hair, such as natural oils, essential oils, clay, etc. That's why you'll see sustainable ingredients on their packaging, such as coconut oil, lavender oil, olive oil, argan oil, or avocado oil, which give your hair vitality and moisture.
They are lighter
As a substitute for liquid shampoos, they contain all the necessary ingredients for proper washing but no water. This means fewer CO2 emissions associated with transport.
They are scented with natural fragrances
Thanks to natural essential oils, your hair will smell pleasant. Instead of a persistent synthetic fragrance, solid shampoos contain natural essential oils that positively affect hair and scalp, and give your hair a wonderful, refreshing, and natural scent.
They are great space savers
Because they are much smaller and lighter than liquid shampoos, given the number of washes you can get with the same amount of product, they save a lot of space. This is actually very convenient in various situations, from emptying bathroom cabinets to packing for an upcoming vacation.
They are great for hair
Solid shampoos contain many essential oils and other fresh/natural ingredients. In addition to alleviating the symptoms of dry and itchy scalp, these natural ingredients promote hair growth, create volume, increase blood circulation, and encourage hair follicle strength. With proper use, hair is light, clean, and full of volume.
They are great for travel
When you travel, camp, or go to the gym, say goodbye to mess and plastic; just pack a solid shampoo in your bag and you're ready to go. Because they don't contain water, they are excellent for air travel. You can take the shampoo with you on the plane without hesitation.
They are multi-purpose
Solid shampoos can also be used for other purposes, such as washing the body, and we have even used them to wash clothes while camping or traveling.
They are cool
Solid shampoos are the latest hair care trend that has attracted many nature and environment lovers. By using it, you will look so cool, you will basically be a trendsetter! You know, those who are always a step ahead of others in terms of trends.
They are economical
One bar of solid shampoo costs the same as a completely average brand of liquid shampoos in a pharmacy.
A few more facts
Solid shampoos have a lower carbon footprint.
The ingredients in solid shampoos are less processed than those in standard plastic packaging. This means less intensive production, where ingredients are not heated and thus do not lose their natural positive properties.
A truck full of solid shampoos is enough for as many washes as 15 trucks carrying liquid shampoos in plastic packaging.
