1
Bring a large pot of distilled water to a boil. Pour 2 c (470 mL) of water into a pot, then place the pot on the stove and turn the heat to medium-high. Allow the water to come to a rolling boil.^{[2]

- Distilled water is preferred, since it’s free of any unwanted minerals that may find their way into their hair, but tap water works just fine, too.
2
Simmer rosemary sprigs for 15-20 minutes. Reduce the heat to medium. Place 3-4 whole, fresh sprigs of rosemary directly into the boiling water, cover the pot, and let it simmer for 15-20 minutes. After about 15 minutes, the water will take on a darker, amber hue.^{[3]
X
Research source} The longer you leave the sprigs in, the stronger your rosemary water will be.
- Optionally, remove the pot from the heat after boiling the rosemary for 5-10 minutes, and let the rosemary steep in the pot for up to 3 hours for a more potent infusion.
- Also, consider adding 1 tsp (1 g) of whole cloves, which has antimicrobial effects that may promote scalp health.^{[4]

Cool and strain the rosemary water into a spray bottle. Take the pot off the heat and let it cool completely for about 30 minutes. Then, strain the rosemary water into a spray bottle and throw out or compost the leftover rosemary. Your rosemary water is ready to use!^{[5]

- Alternatively, store the rosemary water in a sterilized mason jar in the fridge for up to a week, until you’re ready to use it.

Using Rosemary Water in Your Hair

1
Work 3-4 spritzes of rosemary water into your scalp. Part your hair down the center. With your spray bottle, spray the rosemary water directly onto your scalp. (Or, pour 1 tsp (4.9 mL) of the water onto your scalp, if you don’t have a spray bottle.) Then, use your finger to massage the rosemary water all across your head for 2-3 minutes, working your fingers in small circles.^{[6]

- For best results, apply your rosemary right after you get out of the shower, onto clean hair.
- Before you apply it to your scalp, patch test the water by dabbing a bit onto your wrist and waiting for 2 hours to see if you have a negative reaction to the rosemary.
2
Use your rosemary water in the shower as a rinse. If you’d rather not have your hair smell so intensely like rosemary, apply the rosemary water in the shower, just like you would shampoo. Spray a few spritzes onto your scalp, then massage the rosemary water in with your fingers. Let it sit for 10-15 minutes, then thoroughly rinse it out.^{[7]
X
Research source}
- Use the rosemary water before you shampoo or condition if you’d rather mask the smell. Otherwise, use it afterward so that the rosemary has longer contact with your scalp.
3
Use your rosemary water 2-4 times a week. For best results, apply your rosemary water to your scalp at least twice a week. If you like, use it every day to give your scalp plenty of contact with the beneficial compounds in the rosemary. Whatever your schedule, stay consistent! Hair growth is a long process, even when using remedies like rosemary oil—expect results in about 6 months.^{[8]

- To possibly enhance your results, use rosemary oil alongside your rosemary water. Rosemary oil may have a greater concentration of rosemary, and may help moisturize your hair, improving your scalp’s health.^{[9]

Benefits of Rosemary Oil for Hair

1
Rosemary water may speed up hair growth. In a clinical study comparing rosemary oil to minoxidil (or Rogaine), researchers found that, after a period of 6 months, rosemary oil performed just as well as minoxidil to encourage hair growth.^{[10]
X
Research source} Rosemary water contains the same compounds as rosemary oil (but in lower concentration), and so rosemary water may also be an effective hair growth agent.
- The hair-growth properties of rosemary are thanks to carsonic acid, which reduces inflammation, provides antioxidants, and rejuvenates damaged scalp tissues and nerves.^{[11]

Question

How long can I keep rosemary water outside?

Community Answer

It's best to store it in a refrigerator where it will last one to two weeks. Keeping your rosemary water outside will decrease its shelf life by a lot.

Warnings

Some say that using rosemary water darkened their hair slightly. Use half as much rosemary for a lighter infusion, or avoid rosemary for hair growth if you want to preserve your light hair color.^{[18]
