Pickup currently not available
Gloriously Revived Hair Starts Here
If your locks have been through the metaphorical wringer — heat, colour, a brief flirtation with bleach — this clever little shampoo bar may well be the comeback story you've been waiting for. It pampers your scalp with prebiotics and hyaluronic acid, hydrates like a spa but fits in your palm, and offers rather superior sudsing, all while being terribly well-behaved in the bathroom.
Why Choose Our Prebiotic Solid Shampoo?
- Hyaluronic acid infusion: Draws in moisture and holds it tightly, leaving hair plumper, shinier and frankly more show-off worthy
- Vegan keratin complex: Smooths over split ends and breakage like a therapist with better references
- Tomato bioferment: It may sound like lunch but it’s actually your scalp’s new best friend, restoring balance and strength
- Alcohol-free formula: Cleanses with kindness, not with astringent fury — essential for colour-treated or sensitive hair
Product Details:
- Weight: 70g concentrated bar that lasts ages (two to three bottles of shampoo sort of ages)
- Packaging: Nestled in a fabulously recyclable aluminium case for extra smug points
- Certifications: Vegan, cruelty-free and made with certified organic ingredients
- Key benefits: Reduces frizz, repairs damage and supports colour-treated hair in the dignified manner it deserves
Give your routine a glow-up while treating your hair to something rather fabulous. It’s all a bit marvellous, really
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us

We are Sostter
We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
