Rosemary Oil and Hair Growth: What Does the Research Say?

Hair loss is a concern that affects many individuals worldwide. While there are numerous treatments available, natural remedies like rosemary oil have gained significant attention in recent years. But what does scientific research reveal about the efficacy of rosemary oil in promoting hair regrowth?

Understanding Rosemary Oil

Rosemary oil is derived from the Rosmarinus officinalis plant. Traditionally, it has been used for various medicinal and culinary purposes. In the realm of hair care, rosemary oil has been touted for its potential benefits in promoting hair regrowth and combating hair loss.

The Science Behind Rosemary Oil for Hair Growth

A study conducted in 2015 delved into the effects of rosemary oil on hair regrowth. This research compared the impact of rosemary oil to minoxidil, a commonly prescribed medication for hair loss.

Key Findings of the Study:

  1. Comparable Efficacy: The study found that rosemary oil was just as effective as minoxidil in promoting hair growth over a specified period. This is a significant finding, considering minoxidil is one of the few FDA-approved treatments for hair loss.

  2. Reduced Side Effects: Participants who used rosemary oil reported fewer side effects compared to those who used minoxidil. Specifically, those using rosemary oil experienced less scalp itching, a common side effect associated with minoxidil.

  3. Mechanism of Action: While the exact mechanism through which rosemary oil promotes hair growth remains a topic of research, it's believed that its ability to improve blood circulation to the scalp plays a pivotal role. Enhanced blood flow ensures that hair follicles receive the necessary nutrients and oxygen, promoting healthier hair growth.

Incorporating Rosemary Oil in Hair Care

Given the promising results of the study, those interested in natural remedies for hair loss might consider incorporating rosemary oil into their hair care routine. It can be mixed with a carrier oil for scalp massages or added to shampoos and conditioners for regular use.


While more extensive research is needed to fully understand the benefits and mechanisms of rosemary oil for hair growth, preliminary findings are promising. Its comparable efficacy to minoxidil, coupled with fewer side effects, makes it an attractive natural alternative for those battling hair loss. As always, before starting any new treatment, it's advisable to consult with a healthcare professional and conduct patch tests to ensure compatibility.
