01The brief.

Origin

Wild-grown on the Atlas foothills of Morocco and the Cap Bon peninsula of Tunisia — 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 ≥40% 1,8-cineole and ≥12% camphor.

Concentration

Effective range 0.5%–2% in leave-on scalp formulas. Above 3% risks irritation without added efficacy.

02How it works.

Rosemary's active — 1,8-cineole — 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.

CautionAvoid during the first trimester of pregnancy. Patch-test if you have very sensitive skin. Not recommended for children under 6.

  • Benefits
  • ✦Stimulates scalp micro-circulation, delivering oxygen to the follicle bulb
  • ✦Comparable regrowth to 2% minoxidil in a 6-month trial (Panahi et al., 2015)
  • ✦Reduces itchiness and dandruff through antimicrobial 1,8-cineole
  • ✦Balances an oily scalp without stripping the acid mantle

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' — one of the first alcohol-based tonics on record — 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

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.

09People 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.
