Fresh, vibrant, and gently uplifting, the Rhubarb Solid Shampoo Bar by Agnes + Cat brings an energising fruitiness to your hair wash routine. Infused with the tangy, naturally sweet scent of fresh rhubarb and enriched with grape seed oil, this concentrated shampoo bar cleanses thoroughly while leaving hair feeling refreshed, light, and naturally revitalised.
The fragrance is bright and fruity with the characteristic tang of rhubarb — fresh and uplifting rather than sweet or heavy. It wakes up the senses and leaves hair smelling clean and lively without lingering too strongly.
The gentle, pH-balanced formula is suitable for a wide range of hair types including colour-treated hair. Grape seed oil, known for being lightweight and rich in antioxidants and linoleic acid, helps strengthen hair and add shine without weighing it down. One bar replaces up to three conventional shampoo bottles. Free from SLS, SLES, parabens, and palm oil, in elegant zero-waste packaging. Vegan and cruelty-free, handmade in small batches in Sheffield.

Wet your hair thoroughly with warm water. The warmer the water, the better the bar will lather.
Moisten the shampoo bar between your hands and rub together to build up a good lather. You can also rub the bar directly onto wet hair from root to tip.
Work the lather into your scalp with your fingertips, using gentle circular motions. Pay attention to the roots where oils and product build-up tend to accumulate.
Once your scalp is well lathered, work the foam down through the lengths of your hair to the ends. Set the bar aside in a dry spot while you massage.
Rinse well with warm water until the water runs completely clear. A thorough rinse is important with solid shampoo bars to avoid any residue.
For the first few uses while your hair adjusts to a natural formula, you may want to shampoo twice. Most people find one wash is plenty once their hair has settled.
Keep your shampoo bar in a dry place between uses. A soap dish with drainage or a dry shelf away from the direct shower spray will extend the life of the bar considerably. Never leave it sitting in water.
If you are switching from a conventional liquid shampoo, your hair may take a few washes to adjust. This is completely normal. As your scalp rebalances its natural oils, your hair will settle into a healthier, fresher routine. Most people notice a real difference within two to three weeks.
Bright, tangy, and freshly fruity — the natural character of rhubarb with a clean sweetness underneath. Uplifting and energising rather than sweet or heavy, it leaves hair smelling clean and refreshed.
Grape seed oil is a lightweight oil rich in antioxidants, vitamin E, and linoleic acid. It helps strengthen hair, reduce breakage, and add shine without the heaviness of richer oils, making it well suited to fine or normal hair types.
One bar can replace up to three conventional bottles of shampoo, depending on your hair length and thickness. For short to medium hair, expect significantly more washes than a standard bottle.
Yes. The gentle, pH-balanced formula is free from SLS, SLES, parabens, and palm oil, making it safe for colour-treated hair. Many people find their colour stays brighter and lasts longer with a sulphate-free formula.

Yes, completely normal. When switching from a conventional liquid shampoo, your scalp may take a few washes to rebalance its natural oil production. Hair can feel slightly different during this transition period, which typically lasts one to three weeks. Once settled, most people find their hair feels healthier and needs washing less frequently.
Keep your bar in a dry place between uses. A soap dish with drainage away from the direct flow of the shower is ideal. Keeping it dry between washes extends the life of the bar considerably.
