Everything about Cinnamon Oil for Hair (The Science)

It has been scientifically proven in a 2018 study that cinnamon oil can increase the size of hair follicles and stimulate hair growth.

Cinnamon oil has been used for hundreds of years to help hair grow faster and stay healthy. Cinnamon oil can help your hair in a number of ways, but if you don’t do it right, it could do more harm than good.

We looked at a lot of research papers and talked to dermatologists and people who know about hair care to figure out how cinnamon oil affects the hair and the best way to put apply the oil to your hair.

In the sections that follow, we’ll talk more about the methods and the science behind them.

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

Throughout history, cinnamon has been used to treat infections and inflammation. There is some evidence that its high vitamin content may also improve hair health, according to studies.

Cinnamon oil has been scientifically proved to reduce hair loss, according to a 2016 study.

Chemical components found in cinnamon oil that has antibacterial, antiviral, and antifungal effects are also present. These protect your scalp from bacterial and fungal infestations. Hair development is aided by a healthy scalp.

To stimulate the scalp and enhance blood flow, cinnamon oils have been shown to be extremely effective. Hair growth is impossible without enough blood flow to the scalp and hair follicles.

Since cinnamon oil contains antioxidants, it can help fight inflammation and protect the skin from the damaging effects of the sun’s ultraviolet rays. Cinnamon’s numerous benefits to hair and scalp health are well-documented.

Cinnamon oil contains a flavonoid antioxidant called procyanidin, which has been shown to have potent therapeutic effects on hair follicles. By boosting the formation of hair epithelial cells, these polyphenol chemicals are thought to stimulate hair growth.

How to Make Cinnamon Oil for Hair Growth?

  1. Both ground cinnamon and cinnamon sticks can be used to make Cinnamon oil. Use a cinnamon stick if at all possible. They have a more distinctive flavor than cinnamon powder.
  2. Next, select a carrier oil based on your specific requirements.
  3. Fill half of a glass jar with cinnamon sticks or ground cinnamon.
  4. Fill the rest of the container with your preferred carrier oil. Cinnamon sticks or ground cinnamon should be completely submerged.
  5. Place the jars on a warm, dry surface, such as a windowsill, and tighten the lids. Leave them in place for a maximum of three weeks. In this way, the cinnamon’s flavor and some nutrients can be released into the oil.
  6. Every day, shake the jar. This will help infuse the base oil with cinnamon and prevent mold from forming on the oil’s surface.
  7. Strain the oil into a new, sterilized glass jar when the three-week steeping period is complete.
  8. Once the oil has been placed into the new jar, seal the jar with a lid that has an undamaged rubber seal. Cool, dry places like your pantry or refrigerator are ideal for keeping the oil safe and fresh.

How to Choose the Best Carrier Oil for Cinnamon Oil?

There are so many carrier oils on the market that it may be hard to decide which one to use. If you want the best results, choose a carrier oil that is 100% pure. Using pure carrier oil keeps the chemical makeup of cinnamon oil safe and makes sure it can be dissolved. If not, the carrier oil could stop the cinnamon oil from having the effects or benefits you want.

Don’t use carrier oils like petroleum jelly, vegetable oils, and butter because they don’t get deep enough into the scalp and hair to absorb the active ingredient.

To make it easier for you to choose a carrier oil, we’ve made a long list and put it into categories that match your needs.

Pro Tip: 

Nut-allergic individuals should avoid using oils made from tree nuts, since they may provoke an allergic reaction. Oils derived from apricot kernels, argan, and almonds all belong to this category.

How to Dilute Cinnamon Oil for Hair and Scalp?

A few drops of cinnamon oil are all you need. Don’t put cinnamon oil straight on your scalp because it could irritate the skin or cause an allergic reaction. Follow the directions on the label about how much water to add to the oil.

If you are allergic to cinnamon, try a small amount of the oil on your scalp or skin to see if it makes you sick.

Dilution Proportions:

  • For 10% dilution, you need to mix 5 teaspoons of carrier oil with 50 drops of cinnamon oil.
  • For 5% dilution, you need to mix 5 teaspoons of carrier oil with 25 drops of cinnamon oil.
  • For 3% dilution, you need to mix 5 teaspoons of carrier oil with 15 drops of cinnamon oil.
  • For 2.5% dilution, you need to mix 5 teaspoons of carrier oil with 4 drops of cinnamon oil.

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

Cinnamon oil is so concentrated that even small amounts can be effective. Essential oils like cinnamon oil must be mixed with a carrier oil like olive, jojoba, or grapeseed oil.

Experts say that putting cinnamon oil on the surface of the hair won’t help and will only make the scalp oily. If you want to get the most out of oiling your hair, you need to know how to do it right.

In the sections that follow, we’ll talk in more detail about the method and the research that went into it.

Step 1: Prepare your Hair

We’ll use a wide-toothed comb to untangle the hair and get rid of any knots. When cinnamon oil is used in this way, less damage is done to the hair. This also makes sure that the oil gets to all parts of the scalp and hair in an even way.

Straighten each section from the roots to the ends to straighten your hair from the top to the bottom.

Step 2: Prepare the Cinnamon Oil

The molecules in cinnamon oil are substantially larger than hair follicles on the scalp due to the manufacturing process. As a result, cinnamon oil cannot reach the hair follicle and have the desired impact at room temperature.

Warming cinnamon oil solves the problem by breaking up the oil molecules and making it easier for the oil to penetrate the scalp and hair. The medicinal effects of heated cinnamon oil are enhanced. This is good for colored or damaged hair. The hair’s cuticle is sealed by heat, helping it to retain moisture.

Mix around 3–4 teaspoons carrier oil with 7 drops of cinnamon essential oils

Note: Cinnamon Essential oils must be diluted due to their high concentration.

Heat the oil mixture in a microwave-safe dish (a glass bowl is recommended). Apply a patch test to your hand to make sure the cinnamon oil isn’t too hot and that you won’t have an allergic reaction.

Step 3: Apply the Cinnamon Oil

We’ll start with the scalp, then move on to the crown, and finish with the rest of the hair. To make your hair grow faster, use your fingertips to massage your scalp in a circular motion. Before you put oil on your hair, massage your scalp well with your fingertips.

Cinnamon oil is something you should use with care. When there is too much oil, you have to wash your hair more often, which takes away from the benefits of oiling. When you shampoo your hair too much, you strip it of its natural oils and nutrients. This makes it dry, brittle, and dull.

Step 4: Get Rid of Knots

Once more, the wide-toothed comb will be used to untangle any knots that may have formed while the oil was being applied. This lets the cinnamon oil get to parts of the head that it couldn’t get to before. This makes it less likely that your hair will break while you wash it.

Be careful when you comb your hair after getting a massage. The massage will have loosened the cortex and roots, making them more likely to get hurt.

Step 5: Cover your Head

For the next 15 to 20 minutes, we must cover our heads with a shower cap or a cotton T-shirt. This will make you feel warm and also open up the pores on your scalp and cuticles. If you do this, the cinnamon oil will get into your scalp and hair follicles better.

Note: Because towels are rough, you shouldn’t wrap them around your head because friction could damage your hair.

Step 6: Wash Off the Cinnamon Oil

The oiling process is finished with a gentle shampoo and a rinse with warm water. Wash your hair with lukewarm water to open your pores and get rid of extra oil and dirt.

We must now wash our hair with cold water to close the pores that just opened and keep the moisture in.

How to Choose the Best Cinnamon Oil?

All of the studies and research we’ve talked about so far show that cinnamon oil may be good for hair health. But you won’t get any of these benefits if the cinnamon oil isn’t good. When looking for the best cinnamon oil for hair, consider the following:

  • Make sure the cinnamon oil can be used in beauty products. This information is usually written on the back of the container.
  • Make sure the bottle of cinnamon oil is always dark and made of glass. By keeping out light, the black color of the bottle keeps the cinnamon oil from going bad.
  • Whenever possible, use a well-known brand.

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

Some people have been able to get their hair to grow faster by using cinnamon.

Both science and personal experience show that cinnamon essential oil can help keep hair from falling out.

Cinnamon essential oil is a simple treatment that can be done at home, and it may even work as well as products sold in stores. Also, when done the right way, it is pretty safe and doesn’t have many bad effects.

You only need to put cinnamon oil on your scalp to make your hair grow faster and thicker. Because each hair shaft below the scalp controls the growth factor, you do not need to put oil on your hair in this case.

  • Warm up two to three teaspoons of cinnamon oil with olive, coconut, or castor oil.
  • Apply the cinnamon oil mixture to your scalp by making small swirls with your fingers.
  • Cover the area with a shower cap or T-shirt for 15 to 20 minutes.
  • Use lukewarm water and a mild shampoo to remove it carefully.
  • Rinse the pores with cold water to close them.

What to mix with Cinnamon Oil for hair growth?

A study found that the best oil to use with cinnamon oil to make hair grow faster is castor oil. This is because there is a lot of ricinoleic acid in castor oil. Most people’s hair grows between 0.5 and 0.17 millimeters each month.

It has been shown that castor oil makes hair grow faster. As usual, heat the cinnamon oil and castor oil mixture so that it can get deeper into the hair shaft.

How to use Cinnamon Oil as a conditioner?

Cinnamon oil can be used for many things, including to condition hair. Cinnamon oil can be used as a hair conditioner to make hair smooth, soft, and easy to comb through.

  • Apply the mixture to your hair and scalp and rub it in.
  • Rub your fingers through your hair and head to cover them completely.
  • Wear a shower cap or T-shirt over your hair for 15 to 20 minutes.
  • You should rinse your hair with regular water to keep some of the cinnamon oil in your hair.

Risks of using Cinnamon Oil for Hair

People who are allergic to cinnamon should talk to a doctor before using the oil. Even if you don’t eat cinnamon oil, it can still hurt you. Before you put cinnamon oil on your hair for the first time, you should do a patch test.

If cinnamon oil makes your skin red or itchy, stop using it and try a different oil.

Don’t get any of the oil from cinnamon in your eyes or nose. If you do this by accident, wash your eyes with cold water right away.

Don’t use cinnamon essential oil if you’re pregnant or breastfeeding. Because we don’t know enough, women who are pregnant or nursing shouldn’t use cinnamon essential oil. The essential oil for hair loss can be put on the skin, but its effects are not well understood, so it should be used with care.


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

Cinnamon Oil should only be used on hair that is already dry. Make sure you’ve got at least an hour before you start. Cinnamon oil takes at least an hour to work because the molecules are bigger than the pores on your scalp.
Cinnamon oil shouldn’t be used on wet hair because the oil molecules can’t get through the water in the hair shaft and the pores on the scalp.

Can we apply cinnamon oil directly to the hair?

Even in small amounts, cinnamon oil is very concentrated and powerful. So, cinnamon essential oils must be mixed with a carrier oil like olive, jojoba, or grapeseed oil.
To get the effect you want, you only need a few drops of cinnamon essential oil. Putting cinnamon essential oils on your scalp directly can irritate it, so be careful. Always dilute cinnamon oil according to what it says on the package, and never use more than what is suggested.

How long should you leave cinnamon oil in your hair?

Experts and studies say that you should put cinnamon oil on your hair at least two hours before you wash it. How long it takes depends on the style you want and the type of hair you have.
Cinnamon Oil shouldn’t be used for more than ten hours at a time because of how strong it is. If you put cinnamon oil on your scalp for a long time, it could cause irritation, dryness, and clogged pores.

Can you put cinnamon oil in your hair every day? How often should you apply cinnamon oil to your hair?

Only if your hair is dry should you apply cinnamon oil every day. According to experts, oily hair should be treated with cinnamon oil once a week. The product can be used up to twice a week on normal hair.

Is too much cinnamon oil bad for hair?

Yes, too much cinnamon oil can be bad for hair because it means you have to wash it more often. You probably already know that washing your hair too much takes away the natural oils and dries out the scalp and hair. This takes away the benefits of putting oil on your hair and may even hurt it more.
If you put too much cinnamon oil on your scalp, it could block your pores and make you lose your hair.

Can you sleep with cinnamon oil in your hair? Can I leave cinnamon oil overnight?

You can sleep for up to eight hours if you put cinnamon oil in your hair. As soon as you wake up, wash it out. Cinnamon oil can clog hair follicles and cause irritation and inflammation if it is left on for more than eight hours. If you leave cinnamon oil on your hair for too long, it could get dusty and stop your hair from growing.
