Is Rosemary Good For Hair? How To Use It

by Meenal Rajapet

Growing your hair is not an easy task. The biggest concern that most people have while growing their hair is keeping it damage-free and healthy. This is where rosemary may help.

Rosemary (Salvia rosmarinus) is an aromatic herb. It has been in use for ages as an effective hair care ingredient that stimulates the scalp, thereby promoting the growth of healthy hair. In this article, we will look at the possible benefits of rosemary for hair and how you can use it. Read on.

Benefits Of Rosemary For Hair

Rosemary is best known for its hair growth-boosting ability. There are various reasons why rosemary is used for hair growth:

  • Rosemary oil helps stimulate blood circulation to the scalp. This, in turn, can promote hair growth.

A study found that rosemary oil could help in the treatment of adrogenetic alopecia. The study compared the effects of rosemary oil to minoxidil, a medication used for hair loss. The results showed that rosemary oil was as effective as minoxidil nand helped treat itchy scalp better than the latter (1).

Another study done on mice showed that the topical application of rosemary extract stimulated hair growth (2). Hair loss was triggered by testosterone in this case.

Another study showed that aromatherapy with rosemary oil and other essential oils could help improve alopecia areata in patients (3). The patients who massaged the essential oils into their scalp daily showed hair regrowth compared to those who used the carrier oil alone.

  • Rosemary oil has anti-inflammatory and analgesic properties (4), (5). These properties may help soothe the scalp.
  • Rosemary oil exhibits antifungal properties against Malassezia furfur, fungi that cause dandruff (6). This helps in getting rid of dandruff and curbing hair fall.
  • The oil from the herb helps clean the hair follicles by unclogging them. Clogged follicles often lead to problems like dandruff, and, in extreme cases, hair fall.
  • It repairs damage while removing dirt and grime that may keep the hair weighed down.

Here’s how you can use rosemary to aid hair growth.

How To Use Rosemary For Hair Growth

1. Rosemary Hot Oil Treatment

Hot oil treatment might be a great way to deep-condition the hair. The process is believed to be time-efficient and requires minimal ingredients. Hot oil treatment may be beneficial to tackle dry and damaged hair while improving scalp health.

You Will Need

  • 2-4 drops of rosemary essential oil
  • 2 tablespoons of carrier oil (coconut, olive, or almond oil)
  • How the towel/Shower cap
  • Shampoo
  • Conditioner

What You Have To Do

  1. Mix the rosemary oil and the carrier oil of your choice. Heat the mixture until it is warm. Do not heat the oils in a microwave as it may result in nutrient loss.
  2. Section your hair and massage the oil into your scalp for about 10 minutes.
  3. Work the oil along the length of your hair until the roots and tips are well covered.
  4. Wrap a hot towel (use a blow dryer to heat your towel) around your oiled hair. Alternatively, you can cover it with a shower cap.
  5. Wait for a minimum of 30 minutes with the towel wrapped around your head before you wash the oil out. The warm environment will allow for maximum penetration and absorption of nutrients.
  6. Rinse the oils out of your hair with your regular shampoo. If you have oily hair, you can skip conditioning.
  7. End the wash with a cool water rinse to seal your cuticles.

How Often You Should Do This

You can treat your hair to a hot oil treatment up to 2 times a week.

Note: Do not overheat the oil as it may not only burn your scalp but also result in nutrient loss. Do not be afraid to oil your hair if it is greasy, to begin with. More often than not, greasy hair is a result of a lack of moisture.

2. Rosemary Leave-in Conditioner

Rosemary improves blood circulation in the scalp and promotes hair growth (1). Using it as a leave-in conditioner may leave the hair feeling glossy and soft. It may also be a good treatment for people with itchy or dandruff-ridden scalps.

You Will Need

  • 1 tablespoon of rosemary leaves/ 15 drops of rosemary essential oil
  • 1 cup of water
  • Tea infuser
  • Spray bottle

What You Have To Do

  1. Measure a cup of water and boil it.
  2. Add about 15 drops of rosemary essential oil to the boiled water. Alternatively, if you are using dried rosemary leaves, you can steep the leaves in the boiled water using a tea infuser for 10 minutes.
  3. The essential oil and water mixture will carry no color, while the steeped rosemary tea will be pale green.
  4. Pour the mixture into a spray bottle.
  5. Wash your hair and spray it with the rosemary-infused water while your hair is still damp. Ensure that you cover most of your hair and scalp.
  6. Let your hair air dry.

How Often You Should Do This

You can use this leave-in treatment every time you wash your hair, and also in between washes to freshen your hair up.

Note: Do not use this treatment in case you have high blood pressure or are pregnant.

3. Rosemary Water (Rosemary Hair Rinse)

Rosemary hair rinse may make your hair shiny and manageable. It may stimulate the scalp and prevent hair loss.

Note: Ensure that the rosemary water has completely cooled before you pour it through your hair. Warm water can open the cuticles, resulting in moisture loss.

Note: Use the shampoo for longer than a week for your hair to adapt to it. It may look greasier than usual during the first week.

5. Rosemary Vinegar

Sometimes, slow hair growth may be caused due to building up of dirt and product residue. The dirt and product build-up may clog your follicles and also form deposits on your hair shaft. A good way to tackle this is by using a rosemary vinegar rinse.

You Will Need

  • 1 cup of apple cider vinegar
  • 3-4 sprigs of fresh rosemary
  • 2 cups of water

What You Have To Do

  1. Crush the sprigs of fresh rosemary and soak it in the apple cider vinegar in a cool and dark place for at least 2-4 weeks.

  3. Use this mixture as a final rinse after you shampoo and condition your hair.

How Often You Should Do This

Use this rinse once a month in addition to other rosemary treatments.

Note: Do not use too much of the rosemary vinegar. If you have dry hair, use a smaller amount to keep your hair from getting dehydrated.

In addition to the above-mentioned ways, rosemary can be used with other oils to promote hair growth. Given below is a list of such oils.

Other Oils To Use With Rosemary Oil

1. Olive Oil

Olive oil has a moisturizing nature (7). This makes it perfect for dry hair. It may condition the hair and seal the cuticle without weighing it down. Olive oil may work as a carrier oil when used with rosemary.

2. Coconut Oil

Coconut oil penetrates the hair shaft easily and reduces protein loss from both damaged and undamaged hair (8). The coconut oil -rosemary combo may act as the ultimate hair care solution for maintaining scalp health.

3. Sage Oil

Studies show that sage essential oil can act as a hair growth stimulant (9). This essential oil, in combination with rosemary, may prevent hair loss and promote hair growth.

4. Peppermint Oil

Mice studies show that peppermint oil can promote hair growth and improve blood circulation (10). Combining rosemary, sage, and peppermint essential oils may help in thickening of hair.

5. Castor Oil

Castor oil can help increase the luster of hair (11). It is also commonly used to aid hair growth, though there is no scientific evidence to prove this effect.

6. Lavender Oil

Mice studies show that lavender oil can promote hair growth (12).

7. Tea Tree Oil

Tea tree oil has anti-inflammatory, antibacterial, and antiseptic properties (13). It can also help in treating dandruff (14).

8. Jojoba Oil

Jojoba oil is a waxy ester and can work great as a moisturizer (15). It is believed to have a similar structure to that of sebum, which is secreted by the scalp. It may be the perfect carrier oil that can be used in combination with rosemary.

9. Almond Oil

Almond oil contains nutrients that are essential for healthy hair growth, like omega-3 fatty acids, vitamin E, magnesium, and phospholipids (16), (17). When used in combination with rosemary oil, it may improve blood circulation and provide nutrition for better hair growth.

How Long Does It Take To Notice The Effects Of Rosemary On Hair Growth?

The effects of rosemary on hair growth may be seen after a month of using the herb. Regular use of the herb may boost the rate at which the hair grows and increase its volume. Do not switch between too many ingredients. As everyone’s hair is different, one should figure out what works best for their hair and stick to it.

Growing out hair is a long process, and there are no shortcuts to it. While one can use ingredients, such as rosemary, to meet their hair goals, there is no miracle solution that will make the hair grow long overnight. Hence, it is important to follow a proper hair care regimen and be patient.
