The Science

A synergistic blend of skincare actives and superfoods

Hyaluronic Acid

The gold standard in skincare, hyaluronic acids act synergistically on the hair: Water-soluble hyaluronic acid hydrates the surface, while oil-soluble hyaluronic acid hydrates from within.

Avocado Oil

Rich in oleic acid—one of the only fatty acids small enough to permeate the hair shaft—avocado oil conditions from within, minimizing water loss and frizz and maximizing hydration and shine.

Hemp Seed Oil

Rich in fatty acids and proteins, hemp seed oil seals the cuticle and strengthens its structural integrity, restoring hydration and elasticity. Because your blonde should bend, not break.

Rice Bran Oil

Vitamin-rich and lightweight, rice bran oil coats the hair and seals the cuticle. Less frizz and static, no greasy residue—just silkier, shinier hair. It’s hydration without the heaviness.
