Putting a coat of rosemary oil on your hair isn’t going to do anything aside from giving you a greasy look. “You want to apply it to the scalp as a treatment,” instructs Dr. Khetarpal. “Really focus on working it in.” 2. **Give rosemary oil time to work**. Let the rosemary oil sit and do its thing for at least a few hours. Dr. Khetarpal suggests using rosemary oil at night and then washing your hair in the morning. 5. **A little goes a long way**. A few drops of rosemary oil may be all it takes for an application. It can be added to your shampoo or conditioner, too. 6. **Be patient**. One use of rosemary oil isn’t going to give you a bushy head of hair. “You’re going to need to use it two or three times a week for six months to see meaningful improvement,” notes Dr. Khetarpal. “Stay consistent and give it time.” #Pasted Rosemary has been reported to have various effects on hair. It has been found to stimulate and improve circulation throughout the body, including the scalp, which can help promote hair growth (Lall & Kishore, 2014). The increased blood supply to the skin is thought to contribute to a more youthful appearance (Lall & Kishore, 2014). Rosemary oil is commonly used in aromatherapy, cosmetics, and perfumes due to its natural properties (Lall & Kishore, 2014). Studies have shown that rosemary oil can promote hair growth and reduce sebum secretion, making it suitable for treating greasy hair (Lourith & Kanlayavattanakul, 2013). The active components of rosemary oil, such as rosmarinic acids and other caffeic acid derivatives, have antioxidant effects that contribute to its biological activities (Lourith & Kanlayavattanakul, 2013). Additionally, rosemary oil can be used for dandruff treatment (Lourith & Kanlayavattanakul, 2013). Rosemary oil has also been found to have wound healing potential. When topically applied, it can promote re-epithelialization and activate hair follicles, leading to improved wound healing (Labib et al., 2019). The high percentage of oxygenated monoterpenes in rosemary oil plays a role in its antioxidant and wound healing properties (Labib et al., 2019). Furthermore, rosemary oil has been studied for its effects on hair loss. It has been found to inhibit 5 alpha-reductase, an enzyme involved in the conversion of testosterone to dihydrotestosterone (DHT), which is associated with androgenetic alopecia (AGA) (Dinkins et al., 2023). In animal studies, topical application of rosemary oil extract promoted hair growth and showed anti-androgenic effects (Dinkins et al., 2023). It was found to be as effective as finasteride and minoxidil, commonly used treatments for hair loss (Dinkins et al., 2023). The inhibitory activity of rosemary oil extract on 5 alpha-reductase was comparable to that of finasteride (Dinkins et al., 2023). In conclusion, rosemary has been found to have various beneficial effects on hair. It can stimulate hair growth, reduce sebum secretion, promote wound healing, and inhibit 5 alpha-reductase, making it a potential treatment for hair loss. The antioxidant properties of rosemary oil contribute to its biological activities and its ability to improve the overall health and appearance of the hair and scalp. Further research is needed to fully understand the mechanisms of action and optimal use of rosemary for hair care purposes. ## Related - [[my hair|hair]] - #Medicinal
