Key Ingredients

Vegan Silk Peptides

Delivers a breathable barrier against external aggressors. It removes carbon particles by 83% removal, improves hair colour protection by 35%, and repairs thermal damage by 72% with each wash. Vegan silk peptides foster a stronger, healthier scalp and hair environment, enhancing smoothness and shine.

Vegan Keratin

Vegan keratin is a resilient protein that works to strengthen the bonds between follicles, allowing roots to grow stronger and reinforcing their structural integrity. By filling the porous gaps of the outermost cuticle composed of overlapping cells, vegan keratin protects, strengthens and repairs fragile and fine strands.

Castor Oil

This multitasking oil is perfect for nurturing fragile hair follicles and feeding strands ample doses of nutrients. Due to its high content of ricinoleic acid, castor oil also protects against hair breakage and fosters stronger strands.

As a vegan alternative to silk peptides, this pioneering ingredient fortifies hair from the root. It delivers a breathable barrier to the hair and scalp - protecting against external aggressors such as pollution, sea or chlorinated water, irritants and bacterial adhesion. Vegan silk peptides improve carbon particle removal up to 83% in one use, improve hair colour protection by 35%, and repair heat damage by 72%. The application of vegan silk peptides yields scientifically-proven results, and fosters a stronger, healthier and more resilient scalp and hair environment, while improving the hair’s smoothness and shine, leaving it silky to the touch.

Keratin is the protein naturally found in the hair, forming the building-blocks of its structure. Vegan keratin is a moisturising humectant that conditions and hydrates the scalp, while also holding anti-irritant benefits. This vegan alternative also protects, strengthens and repairs fragile strands, as well as boosts shine, smoothness and elasticity.

This multitasking oil is perfect for nurturing fragile hair follicles and feeding strands ample doses of nutrients. Due to its high content of ricinoleic acid, castor oil also protects against hair breakage and fosters stronger strands. Castor oil is also a humectant, meaning it is excellent at locking in moisture and enhancing shine.

addressing hair & scalp health at the root


The relationship between hair and hormones starts as we are born and continues through every stage of life. From hair-loss-causing DHT to hair-boosting oestrogen, hormones play one of the most vital roles in our hair and scalp health. The hair growth cycle and the hair follicle structure are directly affected by the hormones in our bloodstream. Fluctuations in sex hormones, stress hormones and thyroid hormones all have various effects on the hair and scalp, and are often the culprits of sudden disruptions in the health of this delicate microbiome. 


Stress compromises the health of your body in a variety of ways, the retention of your hair being one of them. Exposure to stress hormones over many weeks reduces hair growth as hair follicles remain in an extended telogen (resting) phase, a condition known as Telogen Effluvium, whereby up to 70% of growing hairs can abruptly shift into the resting phase (versus the normal 15% that elicits shedding before a new anagen phase).


Through a process called oxidative stress, environmental aggressors (such as cigarette smoke, pollutants, UV radiation or even certain products or foods) can damage various cellular structures in the hair follicle. Oxidative stress breaks down cell tissue and causes DNA damage, which can result in inflammation. Research has shown that oxidative stress also contributes to hair loss by impairing the scalp’s ability to support healthy cell renewal, and in turn, healthy hair growth.


Hair cells are the second fastest-dividing cells in the human body. Each individual has roughly 120,000 hairs on their scalp, all of which require nourishment and fuel to grow and proliferate. Nutritional deficiencies, particularly in iron, zinc, Vitamin D, biotin and Vitamin B12, can impact the hair’s structure, follicle development, immune cell functioning, and ultimately, hair growth. By supporting healthy nutrition, you can support a healthy hair growth cycle.


As we age, the body undergoes many changes and fluctuations, with our hair being no exception. Turning grey is just one of the many changes that confront our hair as we age. In fact, hair ageing affects hair colour, hair curvature, hair diameter and the structural properties of the hair fibre. Research suggests that over 52% of women will experience some form of hair loss by the age of 50, and by the age of 60, approximately 80% will undergo changes in their hair density.
