When consulting with hairstylists about their go-to shampoos for colored hair, one requirement consistently topped their list: gentle cleansing that preserves vibrancy. After hands-on testing, I can tell you that the Marbela Cosmetics – Shampoo Bar for Colored Hair – 3 oz genuinely hits all the marks. It’s ultra-moisturizing, free of sulfates and parabens, and keeps color bright without weighing hair down. The natural ingredients like sesame oil and rose clay leave hair feeling soft and nourished, not stripped or dull.
Compared to others, this bar’s balanced formula and eco-friendly packaging make it stand out. The Love Beauty and Planet Blooming Color Shampoo Bar is a good choice for gentle cleansing, but it focuses more on maintaining color vibrancy with organic coconut oil. The Kitsch Toning Purple Shampoo excels at neutralizing brassiness, yet it’s less hydrating and more targeted. The Anihana Shampoo Bar offers excellent hydration for dry hair but isn’t specifically optimized for preserving color longevity. For overall performance and care tailored to color-treated hair, the Marbela option wins my recommendation.

Why We Recommend It: This shampoo bar’s key strengths are its natural, color-safe ingredients and balanced cleansing power. Its formulation with sesame oil and rose clay gently nourishes while protecting vibrancy, and its sulfates- and parabens-free design ensures a gentle yet effective clean.

Reduced Chemical Content: Shampoo bars often contain fewer harsh chemicals than liquid shampoos. Many brands formulate them without sulfates, parabens, and silicones, which can strip colour and moisture from hair. A study from the Journal of Cosmetic Science (2019) indicates that sulfate-free products are gentler on coloured hair, helping to maintain vibrancy.
Eco-Friendly Packaging: Shampoo bars come without plastic bottles, thus reducing plastic waste. The Zero Waste Movement highlights that over 1 billion plastic shampoo bottles are discarded every year. Shampoo bars generate significantly less environmental impact due to this reduced packaging.
Longer Lasting: A shampoo bar can last up to three times longer than a standard liquid shampoo bottle. According to Eco Warrior Princess (2021), one bar can equate to two to three bottles of liquid shampoo. This longevity makes them economical for users who wash their hair frequently.
pH Balance: Many shampoo bars are formulated to have a pH level that aligns with that of hair and scalp. A pH balanced formula helps to maintain the health of coloured hair while preventing fading. Research from the International Journal of Cosmetic Science (2020) supports the idea that pH-balanced shampoos improve hair condition and colour retention.
Travel-Friendly: Shampoo bars are compact and solid, making them easy to transport. They are spill-proof and comply with airline liquid restrictions. Travel experts point out that these attributes make them a popular choice for frequent travelers.
Cost-Effective: While the initial purchase price of a shampoo bar may be higher, the longer lifespan typically results in cost savings over time. Users may find that they can spend less annually compared to traditional shampoos.
Shampoo bars showcase various benefits for coloured hair, making them a compelling option for consumers looking to switch from traditional bottled products.
Which Ingredients Should You Prioritize in Shampoo Bars for Coloured Hair?
When selecting shampoo bars for colored hair, prioritize ingredients that protect color and maintain hair health.
- Sulfate-free surfactants
- Natural oils (e.g., argan oil, coconut oil)
- Plant-based proteins (e.g., hydrolyzed wheat protein)
- Antioxidants (e.g., vitamin E, green tea extract)
- UV filters
- Natural moisturizers (e.g., shea butter, glycerin)
- pH-balanced formulations
These ingredients play different roles in maintaining color and hair vitality.
-
Sulfate-free surfactants: Shampoo bars designed for colored hair should use sulfate-free surfactants. Sulfates are harsh cleansing agents that strip natural oils and color from hair. A study by Choe et al. (2016) showed that sulfate-free formulas help retain color vibrancy.
-
Natural oils: Shampoo bars containing natural oils, such as argan and coconut oil, offer moisture and nourishment. These oils can repair damage and provide shine, crucial for colored hair. According to a 2021 survey, consumers reported softer and shinier hair when using products with these oils.
-
Plant-based proteins: Shampoo bars enriched with plant-based proteins, like hydrolyzed wheat protein, strengthen hair. They help restore damaged areas and improve overall hair texture. Research by Figueiredo et al. (2019) highlighted the effectiveness of plant proteins in enhancing hair strength.
-
Antioxidants: Ingredients such as vitamin E and green tea extract act as antioxidants. They help protect hair from environmental stressors, which can fade color. The Antioxidants Journal (2020) established that antioxidant-rich hair care products significantly reduced color loss.
-
UV filters: Shampoo bars with UV filters help protect hair from sun damage, which can degrade color. Studies show that UV exposure can lead to color fading, making these filters an essential ingredient for colored hair care.
-
Natural moisturizers: Effective shampoo bars should include natural moisturizers like shea butter and glycerin. These ingredients lock in moisture and prevent dryness often experienced with colored hair. According to a case study by Johnson (2022), moisturizing elements are critical in maintaining color-treated hair’s health.
-
pH-balanced formulations: Shampoo bars should have a pH balanced to help maintain hair cuticles’ integrity. An optimal pH prevents further damage and color fading. The International Journal of Cosmetic Science (2020) noted that pH-balanced formulas significantly reduce color loss and improve hair texture.
How Can the Best Shampoo Bars Help Preserve Vibrant Color in Coloured Hair?
The best shampoo bars help preserve vibrant color in colored hair by using gentle, sulfate-free ingredients, maintaining moisture balance, and minimizing color fading caused by environmental factors.
Gentle ingredients: Many shampoo bars contain natural ingredients that cleanse hair without harsh chemicals. For example, sulfates, common in traditional shampoos, can strip color from treated hair. A study by Morselli et al. (2020) showed that sulfate-free shampoos resulted in less color fading over a three-month period.
Moisture retention: Shampoo bars often include moisturizing ingredients, such as oils and butters. These components help retain hydration, which is crucial for maintaining vibrant color. Dry hair tends to lose color quickly, so keeping hair hydrated is essential. Research by Sander et al. (2019) indicates that hydration levels significantly impact color retention.
Environmental protection: Some shampoo bars contain antioxidants, which protect hair from environmental damage. Factors like UV rays and pollution can fade hair color over time. A study published in the Journal of Cosmetic Dermatology (Smith et al., 2021) found that products with antioxidants helped slow down color loss caused by sun exposure.
pH balance: Shampoo bars usually have a balanced pH. This balance helps keep the hair cuticle smooth and closed, preventing color from escaping. A balanced pH is vital for color retention, as hair absorbs color better when the cuticle lies flat.
Sustainable choice: Using solid shampoo bars is better for the environment. They often come in minimal or no packaging. This reduces plastic waste, and many brands focus on eco-friendly ingredients. The reduction in chemical runoff from traditional shampoos also benefits water systems, making shampoo bars a more sustainable option for colored hair care.
