A common herb in cooking, rosemary is as useful in beauty products as it is in dinner recipes. The aromatic plant has been used in herbal medicines since ancient times when it was believed to help digestion, ease muscle pain and improve memory. Today’s medical studies show rosemary essential oil acts as an antioxidant and antimicrobial, making it a popular ingredient in hair and skin care.
Stimulate Hair Growth
There’s increasing scientific evidence that rosemary oil can help boost hair growth. One study, on mice, showed increased hair growth on animals with hair loss caused by both hormone changes and shaving. It’s thought natural active ingredients in rosemary can help block some of the causes of baldness. Researchers think this now means rosemary shows promise as a hair-growth drug. A previous study on alopecia patients was unreliable because rosemary was combined with several other essential oils and, while the treatment was successful, it was impossible to know which ingredient prompted the hair regrowth.
Soothe a Sore Scalp
Rosemary oil’s property as an anti-fungal makes it a favorite ingredient in scalp treatments. Dandruff is thought to be caused by a form of yeast, so it would make sense to treat it with an anti-fungal. Anti-inflammatories are also recommended for dandruff, which is defined as a chronic inflammation of the scalp. One of the main active ingredients in rosemary, rosmarinic acid, has been shown to have anti-inflammatory and anti-bacterial properties, making it a logical choice to calm the scalp and keep it clean to help avoid infections in broken skin.
