Unlocking the Power of Rosemary Oil: Is This A Natural Solution for Scalp Health?


Unlocking the Power of Rosemary Oil: Is This A Natural Solution for Scalp Health?

Rosemary oil has become increasingly popular in the hair care cosmetics industry, praised for its potential to improve scalp health and promote hair growth. Subsequent research has focused on examining the impact of rosemary oil products on the scalp microbiome and the treatment of various scalp conditions.


What We Know:


  • Rosmarinus officinalis, commonly known as rosemary, is a familiar aromatic household plant characterised by needle-like leaves. This medicinal plant is also renowned for its various beneficial properties, including cardiovascular health, nervous disorders treatment and notably, benefits for hair and scalp health through its ability to enhance microcapillary perfusion (Begum et al., 2023).


  • Rosemary is also known to possess anti-inflammatory properties due to its rich content of phenolic phytoconstituents (Hashem et al., 2024).


  • Moreover, the chemical composition of the plant encompasses essential oils containing primary constituents such as camphene, camphor, cineol and borneol. Additionally, it is known to harbour abundant flavonoids, bitter principles, tannins and terpenoids, alongside amino acids, steroids, glycosides, volatile oils and vitamins (Begum et al., 2023).


Industry Impact and Potential:


  • A study found that rosemary oil was as clinically effective as 2% minoxidil for treating androgenetic alopecia. Additionally, participants using rosemary oil experienced less scalp itching compared to those using minoxidil (Panahi et al., 2015).


  • Hair lotion with 1% methanolic extract of R. officinalis administered in a study on mice demonstrated significant hair growth promoting activity, when compared to the control of 2% minoxidil hair lotion (Begum et al., 2023).


  • An additional study combined rosemary with neem (Azadirachta indica) to create hair gel and leave-in products to treat dandruff. The products were successful, proving more effective than ketoconazole (a conventional antifungal agent) at managing Malassezia furfur, a dandruff-causing fungus, and Trichophyton rubrum, which is also associated with scalp disorders. Their products showed strong anti-inflammatory activity and also proved more effective than minoxidil in promoting hair growth (Hashem et al., 2024).


  • Research like this suggests the potential of medicinal herbs like rosemary as natural and cost-effective ingredients to explore for targeting the scalp microbiome to treat diverse scalp conditions, thereby enhancing overall scalp and hair health (Hashem et al., 2024).
