Organic Rosemary Oil Subscription

Yes, diluted. Never neat.

Undiluted essential oil on skin causes redness, itching and sometimes a burn, and rosemary is no exception. Five to ten drops per tablespoon of jojoba, castor or pumpkin seed oil is the working range. Start at the lower end for your first few applications, and patch test on your inner arm before the first full one. This is the mistake people make most often with rosemary, and it's why plenty of them try it once and stop.

For external use only. Not for children, and if you're pregnant or nursing, speak to your doctor first. People with epilepsy or uncontrolled high blood pressure are generally advised to avoid rosemary essential oil.

The oil suits every hair type, because you're choosing the carrier. That's the part that changes.

Fine hair does better in jojoba, which stays light. Thick, dry or coarse hair takes castor. A scalp that flakes tends to respond to pumpkin seed, which is heavy in linoleic acid. Color-treated hair is fine either way, since the blend goes on the scalp rather than the lengths.

Diluted, and at a lower ratio than you'd use on a scalp. Two or three drops per tablespoon of a facial oil. Patch test on your inner arm and keep it away from your eyes.

If your skin runs sensitive or reactive, leave this one for your scalp and use jojoba or argan on your face.

Scalp comfort changes within a few weeks, and that part you'll notice.

Density is the slow one. Hair adds about half an inch a month and a full cycle runs for months, so judge this at three months rather than three weeks. Take a photo of your part line on day one, because recalling it accurately at that distance is harder than people expect.
