Hair is primarily made of protein, and daily exposure to styling, heat, and environmental factors can weaken its structure. Amino acids—the building blocks of protein—can help restore and strengthen hair. Our Amino Acid Conditioner combines these essential amino acids with nourishing Coconut Oil and Jojoba Oil for daily conditioning.

What It Is

Hair needs regular conditioning to maintain its strength and moisture balance. Amino acids, the building blocks of protein, help support hair's natural structure. Our Amino Acid Conditioner delivers these amino acids along with Coconut Oil and Jojoba Oil in a light, creamy texture that smoothes onto hair. Amino acids help strengthen and condition hair, while Coconut Oil and Jojoba Oil nourish and soften. Typically suitable for all hair types, this lightweight formula may help improve manageability and boost shine for healthy-looking hair without weighing it down.

Key Ingredients

AMINO ACIDS

We use Amino Acids because they are fundamental to the human body and are the building blocks that make up proteins. When combined with gentle cleansing agents, they help clean while remaining mild and balanced for the skin and hair. Amino Acids may help moisturise by supporting the skin's ability to retain water.

Coconut Oil is derived from the Coconut Tree. Used in Ayurvedic medicine for over 4,000 years, Coconut Oil is rich in fatty acids and known to nourish, hydrate and soften.
