Everything about Lemongrass Oil for Hair (The Science)

Using 30 volunteers aged 20-60 who had moderate to severe dandruff, a randomized, trial was conducted in 2015. According to the findings, a hair tonic containing only 10% lemongrass oil effectively decreased dandruff in test subjects.

We’ll go over the method and the science behind it in more detail in the sections that follow.

What does Science say of Lemongrass Oil’s Benefits on Hair?

In addition to strengthening hair follicles, lemongrass has astringent characteristics that can be added to your hair. Taken combined, the former preserves your hair healthy for longer, while the latter removes harmful substances from your hair.

One study from 2015 found that using lemongrass oil for a week reduced dandruff considerably.

This oil not only promotes hair growth, but it also relieves itching and irritation of the scalp. Regular application of this oil is said to cause hair follicles to contract, hence reducing hair loss.

A high concentration of antifungal activities can be found in the essential oil of lemongrass. as a result of this when applied on the scalp, it inhibits the growth of fungal infection.

Lemongrass oil can be used to treat infections in the skin, nails, and hair that are caused by candida species. When this treatment is put on the skin, a yeast infection can’t start or get worse.

Because lemongrass oil is antibacterial, it can be used to help bruises and small cuts heal. The wound is cleaned and sterilized, which helps it heal faster. As a natural astringent, it helps to tighten the skin on the scalp and give the hair a natural shine while also making the cortex stronger.

Lemongrass oil has a lot of vitamin A and vitamin C. Both of these things are good for the long-term health of your scalp. Nits on your head are easy to get rid of with lemongrass oil for hair.

How to Choose the Best Carrier Oil for Lemongrass Oil?

There are so many carrier oils on the market that it might be overwhelming. Choose a carrier oil that is 100 percent pure for the greatest outcomes. Lemongrass oil’s chemical makeup and solubility are preserved by using pure carrier oil. Otherwise, the carrier oil may interfere with the desired effects or benefits of the lemongrass oil.

Carrier oils such as petroleum jelly, vegetable oils, and butter should be avoided because they do not penetrate the scalp and hair well enough to absorb the active ingredient.

We’ve collected a comprehensive list of carrier oils and divided them into categories based on your specific requirements.

Try a small amount of the oil on your scalp or skin to find out if you are allergic.

How to Apply Lemongrass Oil to Hair in 6 Steps: As per Science

Lemongrass oil is extremely concentrated, therefore even small doses might be effective. Lemongrass oil needs to be mixed with a carrier oil like olive, jojoba, or grapeseed oil.

Applying lemongrass oil to the hair’s surface, according to experts, is futile and would just make the scalp oily. You must know how to properly oil your hair if you want to get the most out of it.

We’ll delve more into the technique and the science behind it in the sections that follow.

Step 1: Prepare your Hair

We’ll untangle and eliminate any knots in the hair with a wide-toothed comb. Hair damage is reduced when lemongrass oil is administered in this way. This also ensures that the oil is evenly administered and dispersed across the scalp and hair.

Straighten each section of your hair separately from roots to ends.

Step 2: Prepare the Lemongrass Oil

Lemongrass oil molecules are substantially larger than hair follicles on the scalp due to the manufacturing process. As a result, lemongrass oil cannot reach the hair follicle at normal temperature and have the intended impact.

Heating lemongrass oil solves the problem by breaking up the oil molecules and making it easier for the oil to penetrate the scalp and hair. Heated lemongrass oil has more healing qualities. This is also good for colored or damaged hair. The hair’s cuticle is sealed by heat, helping it to retain moisture.

Combine three to four teaspoons of carrier oil and seven drops of lemongrass essential oil in a small mixing bowl.

Note: Lemongrass essential oils must be diluted due to their high concentration.

In a microwave-safe dish, heat the oil mixture (a glass bowl is recommended). Use a patch test on your hand to confirm that the lemongrass oil is not excessively hot and that you are not allergic to it.

Step 3: Apply the Lemongrass Oil

We’ll start with the scalp, then the crown, and then the rest of the hair using lemongrass oil. Massage your scalp in a circular motion with your fingertips to promote hair growth. Massage your scalp well with your fingertips before applying oil to your hair.

Lemongrass oil should only be used sparingly. Too much oil requires more frequent hair washing, which is in direct opposition to the benefits of oiling. Shampooing too much strips hair of its natural oils and nutrients, making it brittle and lifeless.

Step 4: Get Rid of Knots

The wide-toothed comb will be used once more to untangle any knots that may have formed during the oil application. This allows lemongrass oil to reach parts of the head that were previously inaccessible, reducing the risk of hair breakage while washing.

When combing your hair after a massage, be cautious because the massage has loosened the cortex and roots, making them more vulnerable to harm.

Step 5: Cover your Head

We must cover our heads with a shower cap or a cotton T-shirt for the next 15 to 20 minutes. This will give you a warming sensation and open your scalp and cuticle pores. Lemongrass oil will penetrate your scalp and hair follicles more effectively if you do this.

Because towels are abrasive, you should avoid wrapping them around your head to avoid damaging your hair.

Step 6: Wash Off the Lemongrass Oil

The oiling process is finished with a mild shampoo and a lukewarm water rinse. To open your pores and remove extra oil and grime, wash your hair with lukewarm water.

To close the freshly opened pores and retain moisture, we must now wash our hair with cold water.

How to Choose the Best Lemongrass Oil?

Lemongrass oil appears to be beneficial to hair health in all of the studies and research described above. Nonetheless, if the lemongrass oil is of poor quality, none of these benefits will be experienced. When looking for the best lemongrass oil for hair, consider the following factors:

  • Make sure the lemongrass oil is suitable for cosmetic purposes. This information is usually printed on the container’s rear.
  • Make sure the lemongrass oil container is dark in color and made of glass. The black color of the bottle prevents the lemongrass oil from degrading by blocking light.
  • When feasible, use a well-known brand.

How to Use Lemongrass Oil to Promote Hair Growth, Increase Density, and Prevent Hair Loss

It enhances hair growth and helps you maintain healthy traces. If mixed with an effective carrier oil like coconut or olive oil, you will see remarkable improvements in hair fall and growth in your hair. It also works on the texture and thickness of the hair.

Lemongrass essential oil is a simple remedy that may be administered at home, and it may be equivalent to commercial remedies. In addition, it is highly safe and generates little side effects when used carefully.

Diluted lemongrass oil can be used directly to the scalp to increase hair growth and thickness. As the growth factor is managed by each hair shaft beneath the scalp, you do not need to apply oil to your hair in this instance.

  • Warm two to three teaspoons of lemongrass oil in combination with coconut, castor, or olive oil.
  • Apply the lemongrass oil mixture to the scalp with your fingertips in circular motions.
  • Using a shower hat or T-shirt, cover the area for 15 to 20 minutes.

When should we apply lemongrass oil to hair? Wet or dry hair?

Only use Lemongrass Oil on hair that is already dry. Before you begin, make sure you have at least one hour. Lemongrass oil molecules are larger than the pores on your scalp, therefore it takes at least an hour for the oil to penetrate.
Lemongrass oil should not be used to damp hair since the oil molecules are unable to penetrate the water in the hair shaft and the pores on the scalp.

Can we apply lemongrass oil directly to hair?

No, lemongrass oil should not be used directly on the hair.
Lemongrass oil is extremely potent and concentrated, even in little doses. As a result, lemongrass essential oils must be combined with a carrier oil such as olive, jojoba, or grapeseed oil.
