Rosemary Oil for Hair: What Science Says About Its Hair Growth Benefits

Hair loss is a common issue affecting many individuals, with causes ranging from genetics and age to hormonal changes, medications, and infections. While various treatments are available, natural remedies like rosemary oil have garnered significant attention for their potential benefits in promoting hair growth and improving scalp health. 

How Rosemary Oil for Hair Growth Works

Understanding how rosemary oil promotes hair growth involves exploring its various properties and mechanisms of action. Derived from the Rosmarinus officinalis L. plant, rosemary oil has been used for centuries in traditional medicine. Here’s how it works:

  1. Improved Blood Circulation

Rosemary oil is known to enhance blood circulation. A 2016 PubMed Central study demonstrated that rosemary oil could increase blood flow in the skin of rats. Enhanced circulation ensures that hair follicles receive more nutrients and oxygen, which are crucial for healthy hair growth .

  1. Fighting Inflammation

Inflammation is a common culprit behind hair loss. Rosemary oil’s anti-inflammatory properties can soothe the scalp and reduce inflammation. Studies have shown that the compounds in rosemary oil possess significant anti-inflammatory effects. These compounds inhibit the production of inflammatory mediators like prostaglandins and leukotrienes, reducing inflammation and irritation on the scalp. By calming down irritation, rosemary oil helps maintain a healthier scalp, which is essential for keeping your hair strong and preventing thinning.

  1. Battling Oxidative Stress

Rosemary oil is packed with antioxidants. These oxidants are Rosmarinic, Carnosic and Carnosol Acids. These antioxidants fight off oxidative stress, which can cause hair to age and fall out. Antioxidants protect your hair follicles from damage, helping to keep them functioning properly and promoting the growth of healthy hair.

  1. Keeping Infections at Bay

Scalp infections, whether bacterial or fungal, can lead to hair loss. A 2017 PubMed Central research highlighted rosemary oil's effectiveness in managing bacterial infections. By preventing and treating these infections, rosemary oil ensures that nothing stands in the way of your hair growth .

  1. DHT Reduction

Dihydrotestosterone (DHT) is a hormone linked to androgenetic alopecia, or pattern baldness. DHT can shrink hair follicles and shorten the hair growth cycle. Some studies suggest that rosemary oil may help block DHT from binding to receptors in the hair follicles, potentially preventing hair loss related to this condition.

Clinical Studies and Findings

In a 2015 study of the same group, researchers aimed to compare the effectiveness of rosemary oil and 2% minoxidil, a common hair growth treatment, in treating androgenetic alopecia (AGA), a prevalent form of hair loss. The study involved 100 patients with AGA, randomly divided into two groups: one treated with rosemary oil (50 patients) and the other with 2% minoxidil (50 patients). Over six months, participants received their respective treatments and underwent efficacy and safety evaluations every three months, including standardized professional microphotographic assessments at the start, three months, and six months.

Here are the findings:

  • Both groups experienced a notable increase in hair count
  • Both groups experienced more frequent scalp itching but more notably in the minoxidil group compared to the rosemary oil group.

Also, a 2022 Science Direct study of the same group reinforced the findings of this study, showing that rosemary oil had similar efficacy to minoxidil after six weeks of use, further supporting its potential as a viable alternative to conventional hair growth treatments .
