Rosemary water is made by infusing rosemary leaves in hot water, then allowing the mixture to steep and cool.

Fresh or dried rosemary can be used.

May Promote Hair Growth

You’ve likely heard that some studies suggest rosemary water might promote hair growth, though expert opinions are mixed on whether this trend really boosts growth or simply improves hair’s appearance.

While rosemary oil may be safe for use and offer potential hair benefits, research on rosemary water itself is extremely limited.

Experts caution individuals to be aware of potential side effects, carefully follow usage instructions, and avoid rosemary if taking medications for hair loss.

May Add Shine

Your hair could appear shinier after using rosemary water, but experts have mixed views on whether this DIY rinse truly impacts hair health.

Some suggest rosemary’s antibacterial properties may temporarily impart shine, but it doesn’t stop hair loss, cure baldness, grow new hair, or reverse graying.

Caution is wise as rosemary may irritate sensitive skin or trigger allergic reactions in some.

More research is needed on rosemary for hair as the DIY rinse isn’t FDA approved or proven effective, especially for coarse or fine hair.

Who Should Use (or Avoid) Rosemary Water?

Who Should Use (or Avoid) Rosemary Water
Before trying rosemary water on your hair, individuals with specific hair or scalp concerns should proceed with caution.

  • Those who are pregnant or breastfeeding should avoid rosemary due to potential hormone effects.
  • Individuals with dandruff or other fungal/bacterial scalp infections should consult their dermatologist first.
  • Anyone currently taking supplements for hair loss, or who’s being treated for hair loss with medications, shouldn’t try rosemary water or oil.
  • People with allergies to rosemary or other herbs in the mint family should avoid using rosemary water to prevent adverse reactions or side effects like contact dermatitis.

It’s best to do a patch test before applying rosemary water all over the scalp and hair. And as with any new product, start slowly and discontinue use if any irritation develops. Speak with your doctor before trying rosemary water if you have specific hair or scalp concerns.

How Does Rosemary Oil Work for Hair Growth?

How Does Rosemary Oil Work for Hair Growth
So how exactly does rosemary oil help promote hair growth?

The oil contains powerful active compounds that can benefit your scalp and hair in a few key ways:

  1. It has antioxidant, anti-inflammatory, and antimicrobial effects that help maintain a healthy scalp environment.
  2. It improves circulation in the scalp, bringing more nutrients to hair follicles. Better blood flow also oxygenates and stimulates follicles, supporting growth.
  3. Some research indicates rosemary oil may help prevent and reduce hair loss by inhibiting an enzyme linked to alopecia. It may also help reduce shedding.
  4. The active compounds appear to stimulate cellular regeneration and growth in hair follicles, encouraging thicker, stronger, faster growth.

Rosemary oil is thought to work as a natural, side effect-free solution for issues like dandruff, poor growth, and excess shedding. Apply a few drops to your scalp and see if consistent use leads to visibly healthier, fuller hair.

Of course, individual results can vary quite a bit. But the antimicrobial, growth-stimulating properties of rosemary oil make it worth considering as a natural support for optimal hair health and growth.

Using Rosemary Oil for Your Hair

Using Rosemary Oil for Your Hair
When using rosemary oil on your hair, it’s worth considering your hair type.

The oil may react differently on straight, wavy, curly, or coily hair textures.

Discussing your hair goals with a stylist can help determine if rosemary oil is suitable for you.

Does Hair Type Matter?

You’ll want to consider your hair type when using rosemary oil, as different hair types may respond differently.

  • Rosemary oil may help reduce dandruff for those with oily hair thanks to its antifungal properties.
  • Curly hair may benefit from enhanced shine and less frizz from rosemary’s smoothing effect.
  • Dry, damaged hair may feel softer and stronger with rosemary’s antioxidant and moisturizing abilities.
  • Those struggling with thinning hair may see improved thickness, growth and circulation with regular use.

While individual results will vary, the research on rosemary oil’s properties suggests it can provide benefits for all hair types when used safely and consistently.

Any Side Effects?

Rarely will you experience side effects from using rosemary oil on your hair if you follow dosage guidelines and avoid ingesting it.

  • Rosemary oil has minimal side effects when used topically at the proper dosage.
  • However, be aware of potential interactions with medications, allergic reactions, and safety during pregnancy/breastfeeding.
  • Long term safety of regular use is generally unknown.

Consult your doctor before using rosemary oil, especially if pregnant/nursing. Test for skin sensitivity before widespread use. While rosemary oil seems relatively safe for topical application, little research exists on long term impacts, so exercise some caution.


Like a breath of fresh air, rosemary water may nourish your scalp and add shine to your locks.

For luscious hair growth, look to research-backed practices that holistically support your unique hair health through nourishment, scalp massage, and managing stressors.

While the jury’s still out on rosemary water for hair, approach social media hype critically and focus on proven methods for your one-of-a-kind tresses.
