Handpicked Atlantic Seaweed from Donegal

At the heart of our Irish professional hair colour range lies a powerful natural ingredient sourced from the wild Atlantic coastline of Burtonport. Hand-harvested by second-generation seaweed expert Manus McGonagle, our seaweed is gathered using traditional methods that honour both heritage and sustainability.

Growing in the pristine waters off Cloughglass, this exceptional seaweed is carefully selected, air-dried, and hand-prepared to preserve its naturally rich mineral and vitamin content. Sourced through Quality Sea Veg, every batch is fully traceable and produced to the highest hygiene and quality standards, ensuring purity from shore to salon.

Why Seaweed in Hair Colour?

Atlantic seaweed is naturally abundant in iodine, magnesium, calcium, potassium, and essential vitamins that help to:

• Support scalp health during the colouring process

• Deliver added hydration and shine

• Help strengthen and condition the hair fibre

• Enhance smoothness and manageability

• Protect against dryness often associated with colour treatments


By incorporating handpicked Donegal seaweed into our colour formulations, we combine high-performance professional results with the restorative power of the ocean. The result is vibrant, long-lasting colour with enhanced hair feel, shine, and overall condition.

Rooted in Irish tradition and powered by the Atlantic, our seaweed-infused colour brings together nature, science, and salon expertise — delivering beautiful results with care.
