Not all hair oils are the same, and castor oil proves why. It is a game-changer in our hair care routine. More than a traditional hair remedy, it’s scientifically proven that it strengthens our hair.
Believe it or not, castor oil has been trusted for centuries as a natural remedy. Long before these modern formulations existed, this nutrient-rich oil was well known in medicine, food, skincare, and hair care.
In a hair care regimen, the addition of this oil not only supports hair growth but also improves overall hair health and thickness. That’s why shampoos, conditioners, hair masks, hair serums, and lash serums also include castor oil as a key ingredient.
Castor oil
Castor oil is extracted from the seeds of Ricinus communis plant. It has a thick texture and light yellow in color with a subtle mild smell. It contains high content of ricinoleic acid, a fatty acid compound that has unique therapeutic and nourishing properties.
The heating process deactivates the toxic enzyme ricin, so we can safely use it for various purposes. As in past times, it was used as medicine, to induce labor, as a laxative, and to treat eye irritations. Besides this, it is used as fuel and for household use, skincare, and cosmetics.
If you are facing any scalp issues, then use this oil as it has anti-inflammatory, antibacterial, and antimicrobial properties. In hair care, it is valued for root strengthening, hair moisturizing, and for improving the appearance of thicker, healthier hair.
Benefits of Castor oil for our Hair
1. Supports Scalp Health and Circulation
Castor oil contains ricinoleic acid, which makes up 85-90% of its fatty acid content. In addition to its fatty content, it contains proteins, vitamins, and antioxidants that improve hair condition.
Since inflammation in hair weakens our hair roots, adding a hair massage with castor oil can improve micro circulation and show anti-inflammatory properties. In this way, it improves scalp health and promotes hair growth indirectly.
2. Moisturizes Hair Strands
It is rich in omega-9 fatty acids, which seal moisture in our hair shafts. And due to its occlusive nature, it protects the hair cuticle from external damage. Thus, it moisturizes our hair strands and gives them proper nutrition for healthy hair growth.
3. Maintains a Healthy Scalp
If your scalp is dry, flaky, or has dandruff, then your hair must be easily prone to breakage. Use of castor oil treats dryness and dandruff as it contains ricinoleic acid. It shows antimicrobial and anti fungal properties that treat itchy scalps and maintain a healthy scalp.
4. Strengthens hair and Reduces Breakage
Due to the presence of vitamin E, omega-6, and omega-9 fatty acids in castor oil, it strengthens hair roots and reduces hair breakage.
It also acts as a natural emollient, locking moisture into our hair shaft. Thus, it protects hair from a harmful environment and UV rays, reduces moisture loss, and prevents split ends.
5. Deep Conditioning
If you want to deep condition your hair, then the use of castor oil is the best choice. As it is a natural humectant and has high viscosity, which smoothens the outer cuticles of our hair. That is why it is commonly used in hair conditioners, hair serums, and lash serums.
