Rosemary oil: Benefits and risks
THERE’S a campaign online bent on cancelling a very popular hair care product targeted towards black hair, because of allegations that instead of promoting hair health and fullness, it’s instead resulting in brittleness and hair loss. The key ingredient is rosemary, the plant known for its many health benefits both in hair and skin care, and also as an herb in the kitchen.
Aesthetician and hair expert Shay Taylor said the problem mainly lies in overuse, and people not selecting products for their hair type and needs but rather because of social media influence.
“Rosemary has many benefits for the hair. It promotes hair growth in that it is believed to improve circulation to the scalp, encouraging hair follicles to grow hair more effectively,” Taylor said. “It may also help prevent hair thinning or shedding by strengthening hair at the root, and it can help soothe scalp irritation and reduce inflammation, which may support a healthier scalp.”
She said rosemary and infused products bearing the name also help fight dandruff, as it has antifungal and antimicrobial properties that may help reduce scalp itchiness .
“Regular use can lead to thicker, shinier hair due to its strengthening properties,” Taylor said. “It’s a chemical-free alternative to commercial hair growth or scalp treatments.”
But, she said, as with any product, misuse, overuse or using outside recommendations can result in problems.
“Some individuals may experience irritation, itching, or rashes if allergic to rosemary oil,“ Taylor said. “Rosemary oil is potent and may cause skin sensitivity, especially if applied directly without dilution. It’s recommended to dilute with a carrier oil like coconut or jojoba oil.”
She said that excessive use may lead to scalp dryness or irritation, and so it’s best to use in moderation.
“Also, rosemary oil may not be suitable for people with certain conditions like epilepsy or high blood pressure, due to its stimulating properties,” she said. “Using rosemary in moderation and performing patch tests can help avoid potential risks.”
