How does Rosemary work?

Although it's not clear how rosemary works for hair loss, applying it to the scalp irritates the skin and increases blood circulation.

Are there safety concerns?

Rosemary is safe when consumed in amounts found in foods, and seems safe for most people when used as a medicine. The undiluted oil is UNSAFE for use. Taking large amounts of rosemary can cause vomiting, uterine bleeding, kidney irritation, increased sun sensitivity, skin redness, and allergic reactions.

Do not use rosemary as a medicine if:
  • You are pregnant or breast-feeding.
  • You have a seizure disorder.

Dosing considerations for Rosemary.

The following doses have been studied in scientific research:

  • For the treatment of bald spots (alopecia areata): A combination of the essential oils including 3 drops or 114 mg of rosemary, 2 drops or 88 mg of thyme, 3 drops or 108 mg of lavender, and 2 drops or 94 mg of cedarwood, all mixed with 3 mL of jojoba oil and 20 mL of grapeseed oil has been used. Each night, the mixture is massaged into the scalp for 2 minutes with a warm towel placed around the head to increase absorption.
