How to Scientifically apply Black Seed Oil to Hair

In a 2016 study, black seed oil was found to be an ideal solution for both cosmetics and medicine. The study proved black seed oil to be anti-inflammatory, antifungal, antibacterial, and antioxidant.

For hundreds of years, people have been putting black seed oil on their hair to make it grow faster and stay healthy. Putting black seed oil on your hair has a number of benefits, but if you don’t do it right, it could hurt your hair more than help it.

We read a lot of research papers and talked to dermatologists and people who work in the hair care business to find out the best way to put black seed oil on your hair.

In the next sections, we’ll talk more about the technique and the research that went into it.

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

There are numerous health benefits to applying black seed oil, which is made from the seeds of a flowering vine that grows in North Africa, the Middle East, and Southwest Asia.

Thymoquinone is one of many therapeutic chemicals in the oil, and it is responsible for much of its effectiveness. Aside from the antioxidant and anti-inflammatory abilities that make them so useful in treating a wide range of hair concerns, they have many other therapeutic features. The seed and its oil, meanwhile, are being investigated for a wide range of putative health benefits.

According to a study conducted in 2017, herbal hair oil containing black seed oil reduced hair shedding by as much as 76%.

Using a lotion containing 0.5% black seed oil, researchers in 2013 saw considerable improvement in the hair thinning symptoms of 20 female subjects.

In another study, over the course of four weeks, the combination of coconut and black seed oil resulted in a one-inch increase in hair growth. Only 0.43 inches of growth was observed in hairs that had not been treated.

Black seed oil’s fatty acid content also aids in the strengthening, softening, and conditioning of each hair strand. A person’s hair type can vary from dry to oily since sebum production varies from person to person. To keep your hair healthy and shiny, it regulates the amount of oil produced on your scalp.

A potent antihistamine, thymoquinone, is abundant in black seed oil, which makes it ideal for regrowing thinning hair. Hair regeneration is best achieved using black seed oil.

Hair follicle pigmentation is maintained by boosting the performance of hair cells, which in turn helps to prevent graying of the hair.

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

There are various critical vitamins and minerals found in Black Seed Oil that can aid in the growth and health of your hair.

Experts say that putting black seed oil on the surface of the hair won’t change it and will just 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 detail about the technique and the research that went into it.

Step 1: Prepare your Hair

Using a wide-toothed comb, we will first detangle and remove any knots from the hair. This reduces the likelihood of hair breakage when black seed oil is applied. This also ensures that the oil is applied and distributed evenly throughout the scalp and hair.

You can straighten your hair from top to bottom by splitting it into two sections (or four sections if it is thick or wavy) and straightening each area from roots to ends.

Step 2: Prepare the Black Seed Oil

As a result of how black seed oil is produced, its molecules are far larger than hair follicles on the scalp. Therefore, black seed oil at room temperature cannot penetrate the hair follicle and have the desired effect.

This issue can be remedied by warming the black seed oil, which breaks up the oil molecules and makes it simpler for the oil to penetrate the scalp and hair. Warming black seed oil enhances its therapeutic properties. This is very beneficial for damaged or colored hair. A benefit of heated black seed oil treatments that few people are aware of is that they seal the hair’s cuticle, allowing it to retain moisture.

Before considering a hot oil treatment, it is best to consult a physician or dermatologist, as not everyone can use them.

Microwave 3 to 4 tablespoons of black seed oil in a microwave-safe dish (a glass bowl is recommended). Perform a patch test on your hand to ensure that the black seed oil is not excessively hot and that you will not experience an allergic reaction.

Step 3: Apply the Black Seed Oil

First, we will apply black seed oil to the scalp, then the crown, and finally the remainder of the hair. To promote hair growth, massage the black seed oil into your scalp in a circular manner using your fingertips. Before applying oil to your hair, massage the entire scalp with your fingertips.

Utilize only a tiny amount of black seed oil. When there is an excess of oil, you have to wash your hair more frequently, which negates the benefits of oiling. If you shampoo your hair too frequently, its natural oils and nutrients will be stripped away, leaving it damaged, lifeless, and dry.

Step 4: Get Rid of Knots

Once more, the wide-toothed comb will be utilized to detangle any knots that may have formed during the application of the oil. This will reduce the likelihood that your hair will break when you wash it, and it will also help oil reach neglected areas of your head.

After receiving a massage, you must be cautious when combing your hair because the massage has loosened the cortex and roots of your hair, making them more susceptible to injury.

Step 5: Cover your Head

For the following 15 to 20 minutes, we must wear a shower cap or a cotton T-shirt over our heads. This will make you feel as though you are steaming, and it will open the pores on your scalp and cuticles. If you do this, the black seed oil will penetrate your scalp and hair follicles more effectively than if you did not.

Because towels are rather coarse, you shouldn’t wrap your head in them, as the friction could cause damage to your hair.

Step 6: Wash Off the Black Seed Oil

The oiling process concludes with a light shampoo and lukewarm water rinse of the hair. Washing with lukewarm water will help open pores and remove excess oil and grime.

Now we must wash our hair with cold water to shut the newly-opened pores and retain moisture.

How to Choose the Best Black Seed Oil?

All of the studies and research discussed thus far indicate that black seed oil may be beneficial for hair health. However, if the black seed oil is of poor quality, you will not be able to enjoy any of these benefits. Consider the following when searching for the best black seed oil for hair:

  • Make sure the black seed oil is made to be used for cosmetic use. It is often written on the back of the container.
  • Always make sure that the black seed oil bottle is dark and made of glass. By blocking light, the dark color of the container keeps the black seed oil from going bad.
  • Black seed oil should always be 100% pure, unrefined organic oil. “Virgin” is the label for black seed oil that has not been refined.
  • Use a well-known brand if you can.

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

Due to the high concentration of thymoquinone, a potent antihistamine, black seed oil restores hair growth naturally in thinning areas.

The black seed oil contains Omega 3 and 6 macromolecules that improve blood circulation, particularly in the scalp, resulting in rapid hair growth that can be noticed in just a few days. 

If your main reason for using black seed oil is to make your hair grow and get thicker, you should put the oil on your scalp. In this case, you don’t need to put oil on your hair because each hair shaft under the scalp controls the growth factor.

  1. Microwave 2 to 3 tablespoons of black seed oil.
  2. With your fingers, gently massage the black seed oil into the scalp in a circular manner.
  3. Leave it covered with a shower hat or t-shirt for 15 to 20 minutes.
  4. Rinse it gently with lukewarm water and a gentle shampoo.
  5. Rewash with cold water to seal the pores.

What to mix with Black Seed oil for hair growth?

According to a study, castor oil is the best oil to combine with black seed oil to promote hair growth. This is due to the abundance of ricinoleic acid in castor oil. The average person’s hair grows about 0.5-0.17 centimeters every month.

Castor oil has been demonstrated to stimulate faster hair growth. As is customary, it is advisable to reheat the black seed and castor oil mixture so that it can penetrate deeper into the hair shaft.

How to use Black Seed oil as a conditioner?

Black Seed oil can be used in many ways, including as a conditioner for hair. Black Seed oil makes your hair smooth, soft, and free of knots when you use it as a hair conditioner.

  1. Warm up the black seed oil and rub it all over your hair and scalp.
  2. Keep massaging your head and hair with your fingertips until they are all covered.
  3. Wrap your hair in a shower cap or t-shirt for 15 to 20 minutes.
  4. To keep some of the black seed oil on hair, wash it with regular water.

Risks of using Black Seed Oil for Hair

People who are allergic to black seeds should consult a physician prior to applying black seed oil. Even if you do not consume black seeds, their oil may still make you sick. Before using black seed oil on hair for the first time, a patch test should be performed.

If black seed oil causes redness or itching on the skin, you should stop using it and try another oil.


When should we apply black seed oil on hair? Wet or dry hair?

Black Seed oil must always be applied to dry hair. Ensure that you have at least one hour of free time before you begin. This is due to the fact that black seed oil molecules are larger than the pores on your scalp and require at least an hour to penetrate.
Do not apply black seed oil to damp hair, as the water in the hair shaft and the pores on the scalp make it difficult for the oil molecules to penetrate the hair.

Can we apply black seed oil directly to the hair?

Yes, black seed oil can be used straight to the scalp and hair. It is entirely natural and will not harm your scalp or skin when applied. However, black seed oil can be combined with other powerful hair oils to make it even stronger.

How long should you leave black seed oil in your hair?

According to experts and studies, you should apply black seed oil to your hair for at least two hours before washing it. However, the actual duration will depend on the desired style and hair type.
Black Seed oil is so potent that it should not be applied for longer than 10 hours at a time. Long-term application of black seed oil to the scalp might irritate the scalp, cause it to become dry, and clog the pores.

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

If your hair is dry, only then should you apply black seed oil to it every day. According to experts, Black Seed oil should not be applied more than once per week on oily hair. Normal hair types may use the product up to twice per week.

Is too much black seed oil bad for hair?

Yes, excessive black seed oil can be damaging to your hair, as it necessitates more frequent shampooing. And, as you are probably aware, excessive hair washing strips the hair of its natural oils and dries out the scalp and hair. This undermines the benefits of applying oil to your hair and may cause additional damage.
If you apply excessive amounts of black seed oil to your scalp, it may block your pores and cause hair loss.

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

You can sleep for up to eight hours with black seed oil in your hair. Immediately wash it out upon waking. When left on the scalp for more than eight hours, black seed oil can clog hair follicles and cause irritation and inflammation. If you keep black seed oil on your hair for too long, it may attract dust and inhibit the growth of new hair.
