If you’re looking to reduce your environmental impact while maintaining healthy, clean hair, the Ethique Solid Shampoo promises to deliver professional-quality results in an innovative bar format.

ToggleThe beauty industry produces over 120 billion units of packaging annually, with liquid shampoos being one of the biggest contributors to plastic waste. Traditional shampoos are approximately 80% water, meaning you’re essentially paying for and transporting water in plastic bottles. The Ethique Solid Shampoo revolutionizes this concept by removing water entirely, creating concentrated bars that promise the same cleansing power as liquid alternatives while dramatically reducing environmental impact.
Since launching in 2012, Ethique has become a pioneer in the solid beauty movement, preventing over 25 million plastic containers from entering landfills. Their solid shampoo bars combine sustainability with natural hair care principles, using ethically sourced ingredients and compostable packaging. But as eco-conscious consumers become more discerning, the question remains: can this Ethique Solid Shampoo truly replace your traditional liquid bottle while delivering salon-quality results?
A single Ethique solid shampoo bar is equivalent to three 350ml liquid shampoo bottles and can last for 60-80 washes. By switching to solid shampoo, one person can prevent approximately 11 plastic bottles from entering the environment annually, making it a powerful tool in reducing plastic waste while maintaining effective hair cleansing.
Whether you’re a sustainability advocate, frequent traveler, or simply someone curious about innovative hair care solutions, understanding how solid shampoos work can help you make an informed decision about joining the plastic-free revolution. Let’s explore what makes Ethique Solid Shampoo a game-changer in sustainable beauty and whether it deserves a permanent place in your shower routine.
About Ethique Solid Shampoo

The Ethique Solid Shampoo represents a fundamental reimagining of hair cleansing technology. Unlike liquid shampoos that contain 70-80% water, these concentrated bars pack all the cleansing power into a compact, travel-friendly format. Each bar is handcrafted using ethically sourced ingredients, avoiding harmful sulfates in most formulations, and packaged in completely compostable materials that break down within 180 days.
Key Ingredients and Their Benefits
Sodium Cocoyl Isethionate
A gentle, coconut-derived cleansing agent that creates rich lather without stripping natural oils. This mild surfactant is significantly gentler than traditional sulfates, making it ideal for daily use on sensitive scalps.
Cocoa Butter
Ethically traded Ghanaian cocoa butter that nourishes and moisturizes hair while providing the solid structure needed for the bar format. Rich in antioxidants and essential fatty acids for hair health.
Coconut Oil
Sustainably sourced Samoan coconut oil that penetrates the hair shaft to provide deep conditioning while maintaining the bar’s firmness and creating luxurious lather when activated with water.
Stearic Acid
A plant-derived fatty acid that helps create the solid structure of the bar while providing conditioning benefits and ensuring the product maintains its shape during use and storage.
Decyl Glucoside
A mild, biodegradable surfactant derived from renewable plant sources that provides gentle cleansing action while being environmentally friendly and suitable for sensitive skin types.
Essential Oils
Carefully selected natural essential oils that provide therapeutic aromatherapy benefits while delivering specific hair care properties, from stimulating growth to controlling oil production.
My First Impression: Texture, Scent, and Packaging
Upon receiving my first Ethique Solid Shampoo, I was immediately impressed by the completely plastic-free packaging. The bar arrives wrapped in a simple cardboard sleeve with seed paper labels that can actually be planted to grow wildflowers – a delightful touch that reinforces the brand’s commitment to sustainability. The packaging feels premium yet responsible, setting the tone for the eco-conscious experience ahead.
The solid shampoo bar itself is surprisingly substantial, measuring approximately 6cm x 5cm and weighing 110 grams. The texture is firm but not rock-hard, with a smooth finish that feels pleasant to the touch. What struck me most was how different it felt from traditional soap bars – there’s a distinct creamy quality that hints at the moisturizing ingredients within. The bar’s surface has subtle natural variations that speak to its handcrafted nature.
The scent varies dramatically between formulations, but the Clarifying variant I tested first had a fresh, clean fragrance with subtle citrus notes that weren’t overwhelming. Unlike some natural hair care products that can smell medicinal, this solid shampoo offered a pleasant, spa-like aroma that made the washing experience enjoyable without being artificially perfumed.
How to Use It for Maximum Results
Getting optimal results from solid shampoo requires a slightly different technique than liquid alternatives, but mastering the method ensures excellent cleansing performance:
Daily Washing Routine
- Thoroughly wet both your hair and the solid shampoo bar with warm water
- Rub the bar directly onto your scalp in circular motions, or create lather in your hands first
- Work the lather through your hair from roots to tips, focusing on the scalp
- Allow the cleanser to sit for 30-60 seconds to properly cleanse
- Rinse thoroughly with lukewarm water until all residue is removed
- Follow with a conditioner bar or liquid conditioner as needed
Travel and Storage Tips
- Always allow the bar to dry completely between uses to prevent softening
- Store in a well-ventilated soap dish or travel tin with drainage
- For travel, wrap the dry bar in paper or use a dedicated travel container
- Avoid storing in humid environments like shower caddies long-term
- Cut larger bars in half if you prefer a more manageable size for daily use
- Keep away from direct water streams when not in use
For the best lather and longevity, create friction between the wet bar and your scalp rather than trying to work it into a foam first. The heat and friction from your scalp will activate the cleansing agents more effectively, and storing your bar in a dry location between uses can extend its life to the full 60-80 washes promised by the manufacturer.
Best Product Combinations and Layering
Solid shampoos work beautifully with both conventional and sustainable hair care products, but certain combinations can enhance their effectiveness and your overall hair health:
Complete Ethique System
Pair with Ethique’s solid conditioner bars for a fully plastic-free routine. The conditioner bars provide essential moisture that complements the gentle cleansing action of their solid shampoos.
Hydrating Treatments
Follow your solid shampoo routine with natural hair treatments like coconut oil or argan oil masks weekly to maintain optimal moisture levels.
Rotation System
Alternate between different Ethique formulations based on your hair’s changing needs – use clarifying versions weekly and gentler variants for daily cleansing.
⚠️ What to Avoid
Don’t leave your solid shampoo bar sitting in water or humid conditions as it will dissolve quickly. Avoid using overly hot water as it can break down the bar faster and potentially strip your hair. Also, don’t expect the exact same lather as liquid shampoos – solid formulations create a different but equally effective cleansing experience.
My 8-Week Experience: Real Results
I tested multiple Ethique Solid Shampoo formulations on my normal-to-oily hair over two months, using them as my primary cleansing method. My hair had been accustomed to liquid sulfate-free shampoos, making it an ideal candidate to evaluate how well these solid alternatives compare to quality liquid formulations. Here’s my detailed journey with this revolutionary hair care approach:
The transition required adjusting my technique, but once mastered, the solid shampoo provided excellent cleansing power. Hair felt clean and refreshed, though I needed to experiment with different application methods to achieve optimal lather production.
My hair adapted beautifully to the solid shampoo routine. The concentrated formula proved more effective than expected, requiring only small amounts to cleanse thoroughly. No buildup or residue issues when proper rinsing technique was followed.
Hair health remained excellent with consistent use. The solid shampoo provided reliable cleansing power while being gentler than many liquid alternatives. Travel convenience became a major advantage during a business trip.
After two months, my hair looked and felt as healthy as with premium liquid shampoos. The environmental benefits became increasingly meaningful as I realized how much plastic packaging I’d avoided while maintaining excellent hair care standards.
Unexpected Benefits I Discovered
- Significantly reduced bathroom clutter and storage needs with compact bars
- Perfect for gym bags and travel without TSA liquid restrictions
- Cost-effective despite higher upfront price due to concentrated formula
- Motivated me to adopt other sustainable practices in my beauty routine
- Worked excellently with hard water where some liquids had failed
- Created a more mindful, intentional hair washing experience

Final Verdict: Is Ethique Solid Shampoo Worth the Switch?
After eight weeks of comprehensive testing, I can confidently state that Ethique Solid Shampoo successfully bridges the gap between environmental responsibility and effective hair care. This isn’t just a trendy eco-product with compromised performance – it’s a genuinely innovative solution that delivers excellent cleansing results while dramatically reducing environmental impact.
The concentrated formula proves that removing water doesn’t mean removing effectiveness. Once you master the application technique, these solid bars provide cleansing power comparable to premium liquid shampoos while lasting significantly longer. For environmentally conscious consumers, the plastic-free credentials alone make this a compelling choice, but the added benefits of travel convenience and long-term cost savings make it practical for anyone seeking quality hair care solutions.
However, it’s important to acknowledge that solid shampoos aren’t for everyone. Those with extremely dry hair, specific scalp conditions, or those who prioritize ultimate convenience might find liquid alternatives more suitable. The key is understanding that this represents a different approach to hair care – one that requires slight adjustments in routine but rewards you with reduced environmental impact and excellent performance.
