Black Cumin Nigella oil for natural hair growth

Is Black Seed Oil good for natural hair? Studies have shown that Black seed has antimicrobial, antihistamine, antioxidant, sun protection, anti-aging and hair growth promoting properties. These makes it great for promoting natural hair growth. Black seed is also believed to restore hair growth in thinning areas because of its high concentration of Thymoquinone which is a powerful antihistamine. Antihistamine has become a popular alternative treatment prescribed to patients with hair loss to help regrow hair (1).

What is Black Seed Oil

Black Seed Oil is extracted from the Black Seed herb. The seeds are pressed to yield a yellowish to dark amber liquid. This liquid is what is commonly referred to as Black Seed Oil.  

Black Seed goes by several other names such as: Black Cumin, Nigella Sativa, Kalonji, Black Caraway and Roman Coriander.

The chemical composition of Black Seed Oil includes Thymoquinone, Dithymoquinone, Thymohydroquinone, Thymol, Tannins, Flavinoids, Essential fatty acids, Essential amino acids, Ascorbic acid, Iron , Calcium, among others, making it a great medicinal and hair remedy (2).

Pure, unrefined Black Seed Oil is too potent to be used on its own. Therefore, the oil should be diluted in another carrier oil like coconut oil. Once you dilute the oil, you can use it directly on the scalp to reduce inflammation, stimulate hair growth and reduce flakiness and sensitivity.

Benefits of Black Seed Oil on Natural Hair

1. Promotes natural hair growth

Black Seed Oil is rich in nutrients such as Essential Fatty Acids, Ascorbic acid, Iron, Calcium, among others. These nutrients are essential in hair growth and thus regular use of Black Seed Oil can promote hair growth. This study  indicates that Black Seed Oil when used together with Coconut oil indeed promotes hair growth.

2. Maintains the scalp health

As mentioned earlier, Black Seed Oil contains antibacterial, antifungal, anti-inflammatory and antioxidant properties. These properties help maintain a healthy scalp by addressing issues such as dandruff which is caused by microbes such as bacterial and fungus. The Black Seed Oil also keeps the scalp moisturized preventing dryness which is a condition that makes the scalp more prone to dandruff.

3. Promotes moisture retention in the hair

Black Seed Oil is rich in Fatty Amino Acids which are good for sealing moisture on the individual hair strands.

4. May prevent hair loss

Black Seed Oil contains Thymoquinone as a primary active component. It also has anti-oxidant and anti-inflammatory effects which play a key role in preventing hair loss. A study was done on 20 patients with Telogen Effluvium (a condition that leads to shedding of hair due to early entry of hair into the Telogen phase). Out of the 20 patients, 10 were treated with a lotion containing Black Seed Oil on a daily basis for three months. The other 10 were treated with Placebo. At the end of the three months, 70% of the patients treated with Black Seed showed significant increment in hair density and thickness (3).
