Caring for blonde, grey, or colour-treated hair comes with its own set of challenges. From brassiness to dullness and breakage, keeping your colour fresh between salon visits often requires specialised products. Enter the Kitsch Purple Shampoo Bar (91g) – a solid, eco-friendly shampoo that promises to neutralise yellow tones, strengthen hair, and deliver salon-quality results, all while reducing plastic waste.
But does this bar really live up to its claims? Let’s explore what makes it unique and whether it’s worth a spot in your bathroom.
First Impressions: Compact and Eco-Friendly
At just 91g, the Kitsch Purple Shampoo Bar is small but mighty. Unlike traditional bottled shampoos, it comes in a solid form, wrapped in minimal packaging. This makes it ideal for those looking to reduce plastic waste while simplifying their haircare routine.
One bar replaces two bottles of liquid shampoo, which is not only good for the planet but also convenient for travel and storage. Lightweight, mess-free, and compact, it’s particularly useful for those who want to cut down on clutter in the shower.
Neutralising Brassy Tones: Purple Power
The standout feature of this shampoo bar is its purple toning formula. Just like liquid purple shampoos, it works by cancelling out unwanted yellow and brassy tones in blonde, grey, or highlighted hair. The result is a cooler, brighter shade that looks fresh and salon-worthy after every wash.
This makes it especially useful for:
✔ Natural blondes dealing with brassiness
✔ Colour-treated or highlighted hair needing tone correction
✔ Grey and silver hair that tends to turn yellow over time
After consistent use, hair appears shinier, cleaner, and more vibrant, helping you stretch out the time between salon visits.
Strengthening Benefits: Biotin Boost
Beyond toning, the Kitsch bar goes a step further by including biotin, a well-known hair-strengthening ingredient. Biotin helps:
✔ Reinforce hair strands
✔ Reduce dullness
✔ Improve shine
✔ Support overall scalp and hair health
This dual approach – toning plus strengthening – makes it stand out from standard purple shampoos that often focus only on colour correction. The bar not only keeps your hair looking vibrant but also helps maintain its resilience and softness.
Safe for Colour-Treated Hair
One of the main concerns with purple shampoos is whether they strip colour or dry out hair. The Kitsch Purple Shampoo Bar is formulated with a balanced pH and free from harsh chemicals, making it safe for all colour-treated and highlighted hair types.
It cleanses gently without stripping colour or leaving hair feeling coarse, which is crucial if you’ve invested in salon treatments. Whether you’re maintaining platinum blonde highlights or embracing your natural silver, it helps preserve vibrancy while keeping your hair soft and manageable.
Clean, Vegan, and Gentle Formula
The formula is impressive not just for what it includes but also for what it leaves out. This shampoo bar is:
✔ Vegan & cruelty-free
✔ Free from sulphates, parabens, silicones, and phthalates
✔ Made without artificial fragrances
That makes it suitable for sensitive scalps and for those who prefer cleaner, toxin-free beauty routines. It rinses clean without residue, leaving hair feeling light and refreshed.
Eco-Friendly Credentials
Perhaps one of the biggest selling points for UK buyers is the eco-conscious design. By switching from bottled shampoo to this solid bar, you can help reduce single-use plastic waste.
Even better, each purchase is 4Ocean certified, meaning it supports the removal of one plastic bottle’s worth of waste from oceans, rivers, and coastlines. For those aiming to make small lifestyle changes with a big impact, this is a meaningful step.
