“So far [the benefits of rosemary oil for hair growth have] not been scientifically proven on humans,” says Angela, referring to a study on mice, where rosemary oil was used to speed up hair growth. Angela explains that there has been a human study, albeit only on 28 people, each one of whom had a scalp condition called alopecia areata (an autoimmune disorder which results in patchy hair loss). Hair loss caused by alopecia areata is very different from other types of hair loss or slow growth so the findings were limited. “So far, when it comes to science there is no proof,” says Angela of rosemary oil.
