Quick Questions Before You Buy
Why is seaweed good for hair?
Why is seaweed good for hair?
Seaweed is naturally rich in minerals, amino acids and antioxidants that help support the scalp environment where healthy hair grows. It has been used for centuries to nourish skin and hair, and modern research shows seaweed extracts can help improve hydration, strengthen the hair fibre and support scalp health. Seaweed also acts as a natural humectant, helping the hair attract and retain moisture (more than Hyaluronic acid) which can reduce dryness, static and flyaway hair.
When will I start to see results?
When will I start to see results?
Many customers notice their hair feels softer, smoother and more hydrated within the first few washes. Because our formulas focus on supporting scalp health rather than coating the hair, the biggest improvements often appear after 3–6 weeks of consistent use, as the scalp and hair gradually rebalance.
What makes your haircare different from regular shampoo and conditioner?
What makes your haircare different from regular shampoo and conditioner?
Many conventional hair products rely on sulphates and silicones that strip the scalp or coat the hair to create temporary smoothness. Our approach is different. Rather than simply adding seaweed and herbs to a conventional shampoo base, we built our formulas around them. By combining nutrient-rich seaweed, botanical extracts and gentle cleansers, our products are designed to support the scalp and hair fibre itself. The goal isn’t a quick cosmetic coating, but stronger, healthier-looking hair over time.
Is this suitable for sensitive scalps?
Is this suitable for sensitive scalps?
Yes - many customers with dry, itchy or sensitive scalps tell us they experience noticeable relief after switching to our haircare. Seaweed is naturally rich in minerals, antioxidants and amino acids that help support the scalp, and we combine it with gentle cleansers and botanical extracts chosen to help calm, hydrate and rebalance the scalp environment.

Unless you have a sensitivity to essential oils or naturally occurring plant compounds, most people find our formulas very gentle.

"The shampoo and conditioner are amazing - my hair dresser could not believe how soft, less frizzy and good condition my hair is from using them. The lip balm, facial oil and skin repair balm really do help to keep the skin soft and hydrated. Highly recommend!"

With 60- 80% organic seaweed & herbs, our Super Nutrient Haircare is designed to improve hair strength, elasticity & shine. It helps balance hair oils, stimulate healthy hair growth, prevent hair loss & soothe the scalp.

The natural, plant-based formula cleanses gently, while the essential oils of Clary Sage, Rosemary & Peppermint add fragrance & further improve the health of your hair & scalp.

Our Haircare is pH-balanced to ensure it is suitable for all hair/scalp types & is free from harsh chemicals, making it a gentle & effective choice for your hair care routine.
