The brief.
Origin
Wild-grown on the Atlas foothills of Morocco and the Cap Bon peninsula of Tunisia โ regions where the plant's essential-oil concentration peaks thanks to Mediterranean sun and mineral-poor soils.
Extraction
Fresh leaves are steam-distilled within 12 hours of harvest to preserve volatile actives; batches are HPLC-standardised to โฅ40% 1,8-cineole and โฅ12% camphor.
Sustainability
Rosemary is drought-tolerant and requires no irrigation in its native range. Our supplier partners with cooperatives in the Rif Mountains that harvest wild stands on a 3-year rotation to protect regeneration.
How it works.
Rosemary's active โ 1,8-cineole โ is a vasodilator. Massaged into the scalp it widens the tiny capillaries around each follicle, so more nutrient-rich blood reaches the dermal papilla where new hair is built. Studies show that after 90 days of daily use the anagen (active growth) phase lengthens measurably in shedders.

Heritage.
The record
Rosemary has been documented in scalp medicine since Dioscorides prescribed it in his 1st-century De Materia Medica. Medieval European monks distilled it into 'Queen of Hungary Water' โ one of the first alcohol-based tonics on record โ and Ayurvedic and Unani traditions have used the leaf infusion for scalp complaints for over a millennium.
Traditional use
Applied as an infused olive-oil scalp tonic across the Mediterranean; burnt as a purifying smoke in Berber bath houses; brewed with sage as a graying-hair rinse across Southern Europe.
Naturally found in
- Wild coastal shrubland of the Mediterranean
- Cultivated across California and the Pacific Northwest
- Native to Portugal, Spain, Morocco, and Croatia

People often ask.
How long until I see results with rosemary oil?
Clinical data shows measurable regrowth at 90 days when massaged into the scalp daily. Density peaks around the six-month mark.
Can rosemary oil replace minoxidil?
In a peer-reviewed head-to-head trial, rosemary matched 2% minoxidil for hair count at six months, with less scalp itching. It is a strong first-line option for mild-to-moderate pattern thinning.
Do I rinse rosemary oil out?
No. It is designed as a leave-in scalp treatment. Apply to a dry or damp scalp, massage two minutes, and go about your day.
