Technically no. Chemically it is a liquid wax ester, not a triglyceride. We call it an oil because it looks and pours like one at room temperature. The wax ester structure is the reason it behaves so differently from coconut, olive, or argan.

Usually the opposite. The wax esters resemble human sebum closely enough that the skin reads the application as "we already have enough" and may slow sebum production. Counterintuitive but consistent in cosmetic practice.

Not directly. Jojoba does not have hair growth claims and does not need them. It earns its place by conditioning the scalp lipid barrier, carrying essential oils into the skin, and softening the hair shaft. The growth work in our hair oil is done by rosemary and peppermint, not jojoba.

Yes. It is widely used as a face oil for all skin types, including combination and acne prone. Layer over a water based serum, or use as the oil step in a double cleanse. Patch test first if your skin tends to react.

Cool, dark, capped. Unlike most plant oils, jojoba is highly stable and resists oxidation. A sealed bottle keeps for several years. Once opened, use within a year for best feel even though chemical degradation is slow.

A nineteenth century botanist misidentified an early sample as Chinese, and the species name stuck. The plant has nothing to do with China. It is native to the deserts of the south western United States and northern Mexico.
