What Pinene does

Adds a fresh, pine-like scent
Gives a woody, herbal note to blends
Works as a natural fragrance component

Pinene is a plant-derived terpene, a family of natural compounds that give many plants their scent. Its two common forms, alpha-pinene and beta-pinene, are found in pine resin, rosemary, eucalyptus and many other plant oils. In finished products it is used mainly as part of a fragrance blend.

Formulators add it for its clean, green, pine-like aroma, which pairs well with herbal and citrus notes. In a hair mask, its role is mostly scent. Terpenes are volatile, so some of the smell fades during use, and exposure to air can slowly change their chemistry.
