Will This Herb Give Your Hair A Healthy Shine?

Applying plant extracts like rosemary to your scalp and hair strands has become a popular TikTok trend because of the widespread belief that it can improve your hair. In this article, you’ll learn about rosemary water, why some people believe it’s good for your hair, and what scientists say about it.

What Is Rosemary Water?

Michelle F. Henry, MD, a board-certified dermatologist in New York City, said that rosemary water is created by soaking rosemary leaves in water to form an infused fluid.

What Experts Are Saying About Rosemary Water for Hair Health

Is rosemary water the miracle potion, as claimed by TikTokers? This is what experts have to say:

Rosemary Water May Promote Hair Growth

There is some research backing the plant’s potential to promote hair growth. In addition to the 2015 published study which discovered that rosemary oil is just as effective as 2% minoxidil after 6 months of use, a small 2013 study supported rosemary leaf extract’s ability to promote hair regrowth in participants with androgenetic alopecia.

However, Dr. Henry maintains that more research is required to establish a direct relationship.

Rosemary Water May Improve Scalp Health

Rosemary oil may have potential benefits for improving scalp health. The aforementioned 2015 study participants who used rosemary oil were less likely to experience scalp itching than the minoxidil group.

That said, Henry said that specific studies centered on the impact of rosemary oil on scalp health are limited. He also said the focus is on rosemary oil, not rosemary water.

Rosemary Water Makes Hair Shiny

While rosemary could temporarily make your hair shine when you apply it, Dr. Henry is not convinced that rosemary water can enhance hair shine in the long run. He also said that adding a lustrous sheen might improve your hair’s appearance, but the effect is temporary.

Who Might Want To Try (And Avoid) The Rosemary Trend

Most people with healthy hair and no scalp issues can add rosemary water to their care routine. On side effects, rosemary oil is generally considered safe for topical use. However, Henry said certain people could have allergies or sensitivities to it.


While rosemary oil has been linked with certain hair-related benefits, the scientific evidence supporting its effectiveness is limited. Henry said rosemary water could have some positive anecdotal effects on scalp health, hair growth, and the appearance of hair.

However, she also said that individual results might vary, and it is vital to seek professional advice before trying a new hair-care trend.
