Camellia Japonica Seed Oil

Imperial China’s Timeless Hair Elixir

Camellia Japonica Seed Oil—prized as China’s native beauty secret—has graced hair for over 3,000 years. Ancient texts like the Classic of Mountains and Seas (Shan Hai Jing) revered this “noble wood” oil so highly that it was reserved as tribute for imperial courts. Later, both the Compendium of Materia Medica and Farmers’ Diet Manual documented its traditional use in nurturing lustrous, beautiful hair. For millennia, Chinese women have massaged this lightweight, golden oil into their strands, passing down the ritual from mother to daughter. Today, the tradition continues—most notably in Hakka communities, where families still anoint newborns’ delicate hair with this same precious oil, a living testament to its gentle, time-honored care.

Why your hair will love it: This fast-absorbing, non-greasy oil delivers deep conditioning without weighing hair down. Rich in natural moisturizing compounds, it helps smooth the cuticle, enhance shine, and leave hair feeling incredibly soft, manageable, and beautifully radiant.

Olea Europaea (Olive) Fruit Oil 

Mediterranean “Liquid Gold” for Luminous Hair

Olive Oil has been the crown jewel of beauty rituals since ancient Egypt and Greece—so precious it was called “liquid gold.” Legend holds that Cleopatra herself relied on this luxurious oil to maintain her famously lustrous, resilient hair. By the Tang Dynasty, this treasure had traveled the Silk Road to China, where it was quickly embraced for its remarkable ability to transform dry, unruly strands. For over two millennia, cultures across continents have reached for this same golden elixir—proof that true beauty wisdom knows no borders.

Rich in natural fatty acids and conditioning compounds, this time-honored botanical delivers weightless nourishment where your hair needs it most.

Hippophae Rhamnoides (Sea Buckthorn) Fruit Oil

Tibetan Plateau’s Secret for Resilient, Radiant Hair

Sea Buckthorn Fruit Oil has been the guardian of beautiful hair among high-altitude communities for over 1,200 years. First documented in the Yue Wang Yao Zhen (Medical Treatise of the Moon King) and the Four Medical Tantras (Rgyud-bzhi) during the Tang Dynasty, this vibrant orange berry was later celebrated in the Crystal Pearl Materia Medica (Jing Zhu Ben Cao) for its nourishing properties. The story goes that in the 8th century, the revered Tibetan physician Yuthok Yonten Gonpo noticed something remarkable: plateau herders exposed to harsh winds and intense sun maintained strikingly dark, lustrous hair. Their secret? This very oil, pressed from wild sea buckthorn berries and worked through their strands daily.

Rich in rare Omega-7 fatty acids, natural vitamins, and botanical antioxidants, this resilient berry thrives where few plants can—delivering extraordinary conditioning power.

Why your hair will love it: Helps smooth and seal the cuticle for hair that looks healthier, feels stronger, and shines with vitality. Deeply nourishes to improve the appearance of dry, brittle strands and split ends, while supporting hair’s natural softness and resilience. Lightweight yet powerful—nature’s answer to hair that faces daily challenges.

Hydrolyzed Silk Protein

Imperial Dynasty’s Secret for Luxuriously Soft Hair

Silk has been synonymous with luxury and beauty in Asia for over two millennia. Ancient beauty rituals called for grinding silk into fine powder and blending it into nourishing hair preparations—a practice meticulously documented in both the Essential Prescriptions Worth a Thousand Gold (Qianjin Yaofang) and the Compendium of Materia Medica. By the Tang and Song dynasties, silk protein had become a coveted treasure in imperial courts, reserved for the elite to maintain exceptionally soft, lustrous hair. By the Ming and Qing dynasties, it had evolved into a closely guarded secret among aristocratic families—a symbol of refined beauty passed through generations.

Today, we honor this ancient wisdom through modern innovation. Using advanced targeted enzymatic hydrolysis, we’ve transformed silk protein into three distinct molecular weights of hydrolyzed sericin and hydrolyzed fibroin. This sophisticated blend works in harmony with transglutaminase enzyme to deliver comprehensive hair conditioning from the inside out.

Why your hair will love it: Lower and medium molecular weight proteins help penetrate the hair shaft, while higher molecular weight proteins form a protective veil on the surface. This multi-layer approach helps fill and smooth, creating the appearance of fuller, more voluminous hair that feels incredibly soft, looks beautifully radiant, and moves with natural fluidity. Ancient luxury, reimagined for modern hair.
