ACTIVE INGREDIENTS · ROSEMARY OIL

Scalp circulation and a calm green finish.

Rosemary oil has a long history in hair rituals for its capacity to support scalp microcirculation, which is associated with a healthier environment for hair growth. Recent evidence also points to rosemary oil’s potential to support hair density over time. OVESSI uses rosemary oil in scalp formulas at concentrations balanced with other calming ingredients to deliver the circulatory benefit without the scalp irritation that undiluted essential oil can cause.

FREQUENTLY ASKED

Rosemary oil questions

Does rosemary oil support hair growth?
A clinical study comparing rosemary oil to minoxidil showed comparable results in supporting hair density over six months of consistent scalp application. OVESSI uses rosemary oil in scalp formulas as part of a broader ritual approach, supporting the scalp environment alongside other care steps.
Can rosemary oil irritate the scalp?
At high concentrations or undiluted, yes. OVESSI scalp formulas dilute rosemary oil within a balanced carrier and include calming actives to prevent the scalp irritation that can occur with direct essential oil application. Patch-test on a small scalp area if you have a sensitive scalp.
Can I apply rosemary oil directly to my scalp?
Undiluted essential oils should not be applied directly to the scalp. Use OVESSI formulas that contain rosemary oil at a safe, effective concentration. If you prefer DIY application, dilute no more than two to three drops of pure rosemary oil per tablespoon of carrier oil before applying.
How long should I leave a rosemary scalp treatment on before washing?
A pre-wash scalp treatment with rosemary oil is most effective when left on for twenty to thirty minutes before shampooing. For leave-in scalp serums, the formula is designed for overnight or all-day wear. Follow the product directions for the application time that matches the formula type.
