Pure, steam-distilled rosemary (Rosmarinus officinalis) — clinically studied to match minoxidil 2% over 6 months. The hair-growth gold standard.
A 2015 clinical trial in Skinmed found rosemary oil matched 2% minoxidil in regrowing hair after 6 months — without the scalp irritation.
Carnosic acid in rosemary blocks 5-alpha reductase, the enzyme that converts testosterone to DHT (the hormone behind male pattern baldness).
Stimulates blood flow to follicles, delivering oxygen and nutrients to dormant hair roots.
Calms inflamed scalps, helps with dandruff, seborrheic dermatitis, and itchy conditions.
⚠ Always patch-test before first use. Dilute with a carrier oil — never apply essential oils neat.
Avoid during pregnancy. Rosemary essential oil is a known emmenagogue (can stimulate uterine activity).
Hair growth: 12-24 weeks of consistent use (matches minoxidil timeline). Scalp inflammation: 1-2 weeks.
No. Always dilute in a carrier oil. Undiluted essential oils can burn skin.

Reserve Your Bottle →Rosemary essential oil is steam-distilled from rosemary herb and has become the most talked-about natural ingredient in hair care — with reason: a 2015 trial found it comparable to 2% minoxidil over six months for pattern hair loss, with less scalp itch.
Brewoil's rosemary is high-purity, steam-distilled and lab-verified. It is potent and must always be diluted.
In a 1–2% dilution massaged into the scalp, rosemary supports circulation at the follicle and a calm, healthy scalp — the foundation fuller hair grows from.
It also sharpens a room in the diffuser and lends massage blends a clean herbal lift.
Add 8–12 drops to 30 ml of jojoba or sweet almond. Massage into the scalp 5 minutes, leave 30+ minutes, wash. Repeat 2–3× weekly and judge at 12 weeks. Never apply neat.
Rosemary suits anyone working on hair density and scalp health. Avoid during pregnancy without medical advice; patch test the diluted blend.
