Eucalyptus oil for hair: what it is, what it does, how we blend it
Eucalyptus oil is almost all one molecule: 1,8-cineole, the sharp, cool, camphor-like scent of the leaf, which is why a few tenths of a percent are all a hair blend needs.

What it is
Steam-distilled from the leaves of Eucalyptus globulus, the oil is 70 to 85% 1,8-cineole with alpha-pinene and limonene behind it. It is clear, thin and volatile, and one of the strongest-smelling oils in the library per drop. We describe the scent and leave the folklore out.
How it feels on hair
At 0.5% it gives a bright, cool, penetrating scent that softens over an hour. The blend's weight and finish are unchanged.
Who reaches for it
People who like a cool, clean scalp oil and want something stronger than tea tree, and anyone building a winter blend with peppermint. It is not in a signature blend yet.
Where it sits in our blends
No signature blend uses eucalyptus yet, which makes it one for the builder: start from a blend that is close and swap it in, or build from scratch. Every blend is weighed to the gram and the recipe is printed on the label.
How to compose with it
Essential oils share at most 1% of a hair blend; the builder allows eucalyptus up to 1%. Keep it at the low end and pair it with peppermint, rosemary or lemongrass over jojoba with hemp seed and pumpkin seed.
Good to know: Strong oil. Keep well away from the eyes and off a child's face.
