Rosemary water for hair: the best remedy for dandruff, hair loss and itchy scalp

Rosemary water for hair is the new TikTok hit that is going viral right now. Every filmed hair care routine features the magical mixture, and everyone seems to swear by it for making hair softer and shinier. Some even claim that rosemary water also promotes hair growth. Even Henry Cavill (known as Superman) is a big fan of rosemary water himself. Still, we’re always a little skeptical when it comes to trusting TikTok and celebrities, which is why we researched what the research says about it and what benefits rosemary water really brings to hair.

What are the benefits of rosemary water for hair?

There are thousands of TikTokers who swear that rosemary water gave them longer, stronger and shinier hair. But is this true? Is this water the secret to healthy, beautiful hair? Obviously, it’s not just a TikTok gimmick.

What makes it so effective is the essential oil in rosemary. Rosemary oil is a natural remedy that has been scientifically proven to have a positive effect in the treatment of hair loss, as well as on the health of the hair and scalp. It can not only promote hair growth, but also keep your scalp healthy. And as we always say, healthy hair starts with a healthy scalp.

Rosemary contains up to 78 percent 1,8-cineole (eucalyptol), which improves blood flow to the scalp – meaning more oxygen and nutrients go directly to the hair follicles, which in turn promotes healthy hair growth.

Eucalyptol (1,8-cineole) is an essential oil found in large quantities in a variety of plants and is commonly used in the manufacture of cosmetics, to improve the percutaneous penetration of drugs (how substances penetrate the dermis), as a decongestant for the nose and for coughs, in aromatherapy, and in dentistry. Eucalyptol has been used to treat bronchitis, sinusitis and chronic rhinitis, as well as asthma.

Rosemary also has strong antimicrobial, anti-inflammatory and antiseptic properties. In addition, this wonderful medicinal herb is effective against Candida albicans – a type of yeast that causes dandruff. Therefore, it is a useful home remedy for treating dandruff, itching and scalp irritation.

  • promotes hair growth

Can rosemary water really promote hair growth?

Let’s go a little deeper into how rosemary water promotes hair growth, because that seems to be the most requested benefit. Again, the water can make your hair longer, but how? It can boost hair growth by inhibiting hormonal changes that lead to hair loss, improving blood flow to the follicles, acting as an antioxidant and soothing inflammation on the scalp.

Unlike other natural hair growth remedies, there is evidence that rosemary water actually improves hair growth. A study on mice found that rosemary leaf extract can reduce the conversion of testosterone to the form that contributes to hair loss and block hormone receptors in the follicle. It is also believed to dilate blood vessels and improve blood flow to the scalp. Its antioxidant, anti-inflammatory and antifungal effects are also believed to improve scalp health and strengthen hair. The majority of studies actually look at the effects of rosemary oil.

This aromatic herb is also known to darken gray hair and slow down the appearance of gray hair. Due to its high content of antioxidants, it scavenges free radicals and hydrogen peroxide, which are responsible for graying and thinning hair. Rosemary revitalizes hair, removes product and calcium deposits and makes it shiny and soft.

Which hair types benefit the most from using rosemary water?

Although rosemary water promotes hair growth, some derive more benefit from its use than others. Those struggling with thinning hair due to hormonal influences or increasing age may benefit the most from using rosemary oil. It can also help reduce inflammation caused by dandruff.

Are there hair types that should not use it?

Experts caution against using rosemary water with oral or topical medications for hair loss. There is no data on the safety of combining rosemary water or oil with other hair growth medications such as minoxidil. If someone is already using an oral or topical hair loss medication, they should not also use rosemary water without consulting a doctor.

There is also no data on safety in pregnant or nursing women or in children, so these groups should avoid use. In addition, people with sensitive skin should be cautious when using rosemary water on their hair. People with allergies or sensitive skin should perform a patch test by applying rosemary water to their jawline for five nights to test for irritation before applying it liberally to the scalp.
