How Castor Oil Works For Hair Growth
Understanding Castor Oil
Castor oil is a vegetable oil extracted from the seeds of the Ricinus communis plant. It is a colorless or pale yellow liquid with a distinct taste and odor.
The seeds are first dehulled, cleaned, and cooked to remove moisture, then pressed using a screw press to extract the oil. The extracted oil is clarified and refined to produce commercial-grade castor oil, which is used in various applications, including cosmetics, pharmaceuticals, and industrial products.
Mechanism of Action for Hair Growth
Castor oil is widely regarded for its potential benefits in promoting hair health, primarily due to its rich composition of fatty acids and other nutrients. Let’s see how it helps them grow:
- Rich in Ricinoleic Acid: Castor oil contains ricinoleic acid, which has anti-inflammatory properties. This component may help reduce inflammation in the scalp and hair follicles to create a healthier environment for hair growth.
- Moisturizing Properties: The oil acts as a natural emollient, effectively trapping moisture in the scalp. This hydration helps prevent dryness, which could have led to breakage and thinning of hair.
- Nutrient-Rich Composition: Castor oil is high in omega-6 and omega-9 fatty acids and vitamin E. These nutrients are essential for maintaining hair strength and promoting a healthy sheen, which can enhance the overall appearance of your hair.
- Improved Blood Circulation: Regular application of castor oil is believed to increase blood flow to the scalp. This enhanced circulation can provide hair follicles with more nutrients to support healthier hair growth.

I started using this twice a day because I noticed my hairline receding. Didn’t pay attention to track results, now my stylist told me my hair has grown a lot since my last root touch up. I'm impressed! - Bailey

How To Apply Castor Oil For Maximum Benefit

Before applying castor oil on sensitive areas, it's a good practice to patch-test it on your skin.
To use castor oil on hair, it is recommended to mix it with lighter oils (like coconut or jojoba) to make it easier to apply. The mixture should be massaged into the scalp (only once a week) and left on for about an hour before washing out with shampoo and conditioner. This method nourishes your scalp and also helps combat issues like dandruff.
Pro Tip: Before applying castor oil, prepare your scalp such that it’s free from dirt, oil, or styling products. For that, you can wash your hair with a shampoo and then dry it with a towel.
How Long Does It Take To See Results
Castor oil is effective for hair growth for sure. But the time it takes to show results varies from person to person. Some lucky people may see results within just 4 to 6 weeks, while others may have to wait around 3 to 4 months before any noticeable results appear.
Factors Influencing Growth Rate
- Your Hair Type and Condition: Damaged hair may take longer to show improvement.
- Your Overall Health and Diet: A healthy lifestyle supports better hair growth.
- Consistency in Application: Regular use is essential for optimal results.
Potential Drawbacks Of Castor Oil
- Odor: The oil has a distinct earthy smell that some may find unpleasant. If the scent is particularly strong or rancid, it may indicate that the oil has gone bad.
- Difficult to Wash Out: Due to its viscosity, castor oil can be challenging to remove from hair and scalp. So, this might necessitate multiple washes.
- Potential Side Effects: Castor oil is thick and can lead to buildup on the scalp, potentially clogging pores and causing dandruff or itching. Plus, if you have fine or oily hair, you may find that it weighs your hair down.
Pro Tip: To minimize the risk of adverse reactions, perform a patch test on a small area of skin before using castor oil extensively.

I noticed almost immediately that my hair stopped falling out by the handfuls. Within 3 weeks, I noticed new hair growth. But the real test was when I went to my hairdresser and he noticed a difference. He said even the texture was different. - Grenetta D.
