Is Rosemary Water Good For Your Hair?

Rosemary water offers several benefits for a healthy scalp and hair follicles, potentially promoting hair growth. Its anti-inflammatory and antimicrobial properties can help alleviate conditions such as dandruff and scalp psoriasis.

William Gaunitz, a certified trichologist and founder of the hair-growth brand Advanced Trichology, suggests that rosemary can support hair growth by acting as a cleanser and antiseptic for the scalp. “Rosemary water can be beneficial for those suffering from scalp inflammation caused by excess oil and various microorganisms like parasites, fungi, and bacteria. It helps cleanse the scalp and eliminate some of these inflammation-causing microorganisms,” he explains.

Research also supports the potential of rosemary water to promote hair growth. A 2015 randomized controlled trial found that rosemary oil was as effective as minoxidil (the active ingredient in Rogaine) in increasing hair growth after six months of use.

Benefits of Rosemary Water for Your Hair

Rosemary water has gained popularity as a natural remedy for various hair concerns. Its properties provide numerous benefits, from promoting hair growth to enhancing hair texture. Here’s how rosemary water can benefit your hair:

Helps Hair Grow Faster

Rosemary water is celebrated for its ability to boost blood circulation to the scalp. This improved blood flow nourishes hair follicles, encouraging faster and stronger hair growth. Research indicates that rosemary oil, a key ingredient in rosemary water, can be as effective as minoxidil—a widely used hair growth treatment—in addressing hair loss.

Helps Fight Scalp Dandruff

Rosemary water is an excellent ally in the battle against scalp dandruff. Thanks to its antifungal and anti-inflammatory qualities, rosemary effectively fights dandruff. Consistent application of rosemary water can keep your scalp healthy by diminishing the yeast responsible for dandruff and easing the irritation often associated with flaking and itching.

Makes Your Hair Smoother

In addition to its numerous benefits for the scalp, rosemary water can also work wonders for the overall texture of your hair. The nutrients present in rosemary have a remarkable ability to envelop hair follicles, resulting in smoother, more manageable hair. By reducing frizz and imparting a natural shine, regular use of rosemary water as a post-shampoo rinse can leave your hair feeling noticeably softer and silkier.

Recipe for Making Rosemary Water

Creating your own rosemary water at home is a breeze, requiring just two simple ingredients and a few minutes of your time. Follow these easy steps to whip up a fresh batch that will work wonders for your hair:


  • 3 cups of water
  • 2 sprigs of fresh rosemary


  1. Bring the 3 cups of water to a boil in a pot.
  2. Add the two rosemary sprigs to the boiling water.

Potential Side Effects of Using Rosemary Water for Hair

While rosemary water is generally considered safe for use, it’s crucial to be mindful of potential issues:

  1. Contact Dermatitis: If you notice any signs of skin irritation, such as redness or itchiness, discontinue use of rosemary water and seek advice from a healthcare professional.
  2. Allergy or Hypersensitivity: Avoid using rosemary water if you have a known allergy or sensitivity to rosemary or plants in the mint family (Lamiaceae or Labiatae).
  3. Pregnancy and Breastfeeding: Due to its potential hormone-altering effects and limited research, it’s advisable to refrain from using rosemary water during pregnancy or while breastfeeding. Consult with your healthcare provider for personalized guidance.
  4. Possible Hair Darkening: Some users have reported hair darkening or staining from the color of rosemary water. To mitigate this risk, consider using fewer rosemary leaves for a less concentrated infusion, or opt for alternative hair care options if you have concerns about staining lighter-colored hair.


Rosemary water presents a natural approach to potentially boost hair growth and enhance scalp health. While more extensive research is needed to fully understand its effects, initial studies and widespread anecdotal evidence indicate promising benefits. However, it’s essential to recognize that individual results may vary due to the diverse causes of hair loss.
