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.
