For years, TikTok has been awash with videos touting rosemary oil as a solution for healthier hair. Many users claim it has helped them achieve longer, thicker locks. However, experts suggest that rosemary oil alone is unlikely to deliver substantial, lasting hair growth.
“Hair loss is biologically complex and emotionally charged, making it easy to make oversimplified or exaggerated claims,” explains Dr. Oma Agbai, a clinical professor of dermatology at the University of California, Davis School of Medicine. Whereas some individuals may experience a modest benefit, she notes, “this is not comparable to the results we notice with evidence-based treatments.”
The rising popularity of rosemary oil as a hair growth remedy stems from anecdotal evidence shared widely on social media platforms. But what does the science say? And is this natural remedy a viable alternative to established hair loss treatments?
What is Rosemary Oil?
Rosemary oil is an essential oil extracted from the rosemary plant. It’s frequently used in hair and skincare products due to its purported anti-inflammatory and antimicrobial properties. The theory behind its potential hair growth benefits centers on the idea that it can improve circulation to the scalp and reduce inflammation, thereby supporting hair growth. However, the scientific evidence supporting these claims remains limited.
Some studies suggest a possible, albeit small, effect on androgenetic alopecia, the most common form of hair loss in both men and women. Adam Friedman, a professor and chair of dermatology at the George Washington School of Medicine and Health Sciences, emphasizes, “It’s not magic.” Androgenetic alopecia is linked to androgens, particularly dihydrotestosterone (DHT). High levels of DHT, or increased sensitivity to it, can cause hair follicles to shrink, leading to thinner hair and a shortened growth cycle.
Research indicates rosemary may have a minor influence on reducing DHT, but it’s not definitively proven to reduce hair loss or promote visible, sustained hair growth. There’s no conclusive evidence that rosemary oil helps with other forms of hair loss, such as telogen effluvium (temporary hair loss due to stress, illness, or pregnancy), alopecia areata (an autoimmune condition causing patchy hair loss), or scarring alopecia (hair loss due to inflammation leading to permanent damage).
Why Do So Many Believe It Works?
Much of the current enthusiasm surrounding rosemary oil originates from a 2015 study that gained traction on social media. The study compared a rosemary oil solution to 2% minoxidil (commonly known as Rogaine). The results showed comparable improvements in men with androgenetic alopecia. However, dermatologists caution that the improvements observed were modest, the study involved only 100 participants over a six-month period, and crucially, lacked a placebo group. This makes drawing definitive conclusions difficult.
the oil can make hair appear shinier and reduce breakage, creating the illusion of fullness. In some cases, hair loss may resolve on its own after a few months, and this improvement can be mistakenly attributed to the oil.
How to Utilize Rosemary Oil
For those interested in trying rosemary oil, experts recommend mixing a few drops with a carrier oil, such as coconut or jojoba oil, and massaging the mixture into the scalp. It’s generally well-tolerated and rarely causes irritation. However, experts stress that it should be used as a complement to, not a replacement for, proven medical treatments.
What Else Helps?
Beyond topical products, several lifestyle factors contribute to hair health: a balanced diet, adequate sleep, and stress management. Addressing deficiencies in nutrients like iron, zinc, vitamin D, or protein is also important. Avoidance of extremely tight hairstyles (such as tight braids or ponytails) is recommended, as they can lead to traction alopecia.
Dermatologists recommend treatments with scientific backing, including:
- Minoxidil (oral or topical 5 percent): Widely studied and effective for many individuals with androgenetic alopecia.
- Finasterid: Reduces DHT and promotes hair growth (primarily used in men).
- Spironolacton: Often used in women, particularly in combination with other treatments.
- Dutasterid: More potent in reducing DHT, sometimes used off-label for hair loss treatment.
Experts emphasize that both natural and medical treatments lose their effectiveness when discontinued. These remedies can have side effects or interact with other medications, making medical consultation essential.
The search for effective hair loss solutions continues, and while rosemary oil may offer some benefits for certain individuals, it’s crucial to approach it with realistic expectations and consult with a healthcare professional for personalized advice.
