Natural Shampoo Bars New Zealand Inspired

Our conditioning shampoo bars are plant-based and here’s a list of the all-natural products we use in our bars – and why!

New Zealand Botanical Extracts

Harakeke (New Zealand Flaxseed) Oil

High in natural antioxidants and essential fatty acids, Flaxseed Oil helps minimise inflammation, redness, and skin and scalp irritation, softens hair, and moisturises both scalp and skin. 

Horopito Extract

Horopito is one of the world’s oldest flowering plants. Found in New Zealand’s back country, it works as a fantastic antioxidant and conditioning agent and has shown to be effective against external aggressors such as UV damage and pollution. 

Kawakawa Leaf Extract

Sourced from the leaves of the native New Zealand pepper tree, Kawakawa is refreshing, cleansing and mildly stimulating for the hair and scalp. Kawakawa also has antioxidant properties, protecting the hair from external aggressors such as pollution and UV damage.

Kumerahou Extract

Native to New Zealand, Kumerahou is quite simply a natural soap. Rubbing the leaves and flowers of the Kumerahou shrub together creates a natural lather that gently and effectively cleanses without damaging the skin and scalp moisture barrier. Its high Saponin content provides strong antimicrobial action, and also soothes and locks in moisture. Colloquially known as ‘Gumdiggers’ Soap’, Kumerahou’s produces soapy lather when mixed with water.
