How to Use Castor Oil for Hair Growth

For years, the beauty industry has encouraged us to embrace various oils for our hair care routine, from coconut to olive, and even more delicate options like rosemary and lavender. Among these, castor oil stands out as a potential game-changer for promoting hair growth.

Many, including our editors at Stylepersuit, have seen remarkable results when using castor oil to boost eyebrow growth. This success begs the question: can this age-old remedy also work wonders for the hair on our heads? To delve into this topic, we decided to explore the efficacy of castor oil for promoting hair growth.

What is Castor Oil?

Castor oil is derived from the seeds of the castor oil plant Ricinus communis, primarily cultivated in regions such as India, South America, Africa, and China. It is a nutrient-rich oil with a pale-yellow or almost colorless appearance and a subtle mild scent.

Castor oil boasts various medicinal, household, and pharmaceutical uses, along with being a staple ingredient in skincare and cosmetics due to its potential healing properties.

Benefits of castor oil for hair

1. Strengthens and Nourishes Strands: Castor oil is packed with proteins, vitamins, fatty acids, and antioxidants, making it nourishing for both the scalp and hair follicles. This nutrient-rich environment promotes healthier hair growth and stronger strands. It’s no wonder castor oil is increasingly used in hair products to nurture the scalp and support hair health.

2. May Aid in Hair Loss: While there isn’t solid scientific evidence, castor oil is widely recognized in the beauty industry for its potential benefits in addressing hair loss. Some experts believe it can be helpful in certain cases, although definitive studies or FDA approval are lacking.

3. Antimicrobial Properties: Castor oil contains antimicrobial properties that can combat bacterial or fungal overgrowth on the scalp, which can contribute to scalp inflammation and hair damage. Using castor oil may help mitigate these issues.

4. Reduces Scalp Flaking: If you deal with flakiness from a dry scalp, castor oil can be helpful. It acts as a gentle cleanser for the skin. Because it has a polarized nature, castor oil attracts dirt and effectively cleanses the scalp, reducing flakiness.

5. Prevents Hair Breakage: Castor oil contains ricinoleic acid, which may improve blood circulation in the scalp. This can provide better nutrition to hair follicles, resulting in stronger strands and less breakage. Additionally, castor oil acts as a humectant, locking in moisture and shine. Well-moisturized hair is less prone to dryness, damage, and split ends, promoting healthier growth.

6. Enhances Product Absorption: Castor oil is believed to boost the absorption of other hair care products. When included in your regular hair care routine, it helps other products penetrate more effectively. This benefits your hair’s health and growth in the long term, as a clean scalp without residue allows products to work better.

Overall, castor oil offers a range of benefits for hair health, from nourishing strands to potentially aiding in hair loss and addressing scalp concerns. It’s a versatile ingredient that can contribute to healthier, stronger hair when incorporated into your hair care routine.

Considerations for Different Hair Types

1. Dry or Flaky Scalps and Brittle Hair

Castor oil is most beneficial for individuals with dry or flaky scalps and brittle hair. Since it is an oil, it might be too heavy for those with naturally oily hair.

2. Eyelashes and Eyebrows

There’s anecdotal evidence suggesting castor oil can be effective for enhancing eyelash and eyebrow growth. However, it’s important to note that castor oil can be irritating for some individuals.

To minimize the risk of allergic reactions, apply a very small amount to a test patch on your skin before using it on sensitive areas like eyelashes or eyebrows. This localized application may help stimulate regrowth without causing irritation.

How to use castor oil for your hair

1. Apply Sparingly: Since castor oil is thick and potent, a little goes a long way. It’s crucial to use it sparingly to avoid overdoing it and to prevent it from getting into sensitive areas like your eyes.

Start with a testing to ensure you don’t have reactions. Experts recommend using a small amount during application and suggest not using it more than once a week.

2. Use as a 20-Minute Treatment: Warm the oil in your palms before applying it to the roots of your hair and then gently brushing it toward the ends. Leave the oil in your hair for at least 15 to 20 minutes before shampooing it out.

You can wet your hair before applying the oil to help it soak in better. Keep in mind that castor oil can be sticky and challenging to work with due to its thick consistency. Avoid applying it directly to your hair to prevent it from being difficult to remove.

Using castor oil on lashes and eyebrows

1. Clean Your Lashes and Brows: Ensure your eyelashes and eyebrows are clean and free of any makeup before applying castor oil.

2. Apply to Eyelashes: Dip a cotton swab into a small amount of castor oil. Close your eyes and gently swipe the oil along your eyelashes, making sure to avoid getting it in your eyes.

3. Apply to Eyebrows: Using the same technique with a clean cotton swab, apply the castor oil to your eyebrows. Be careful not to go beyond the brow line, and use a tissue to wipe off any excess oil. Castor oil can be sticky, so be cautious during application.


Does Castor Oil Increase Hair Growth?

The answer is uncertain. While there’s no direct evidence that applying castor oil to your scalp or hair will directly boost hair growth, it can indirectly support it. Castor oil has anti-inflammatory properties and is rich in omega 6 and 9s, as well as vitamin E, which can promote scalp health.

Using it regularly, alongside other dermatologist-recommended products, may lead to positive hair growth results, especially for those with inflammatory hair loss. However, it’s not effective for severe male or female pattern hair loss or nutritional hair loss.

How Often Should You Apply Castor Oil?

For scalp health and healthier-looking hair, apply castor oil two to three times per week. In severe cases, it can be used daily, but mixing it with 50% coconut oil is recommended to avoid sticky buildup.

Massage the oil into your scalp, leave it on for 45 minutes to an hour, then wash it out with shampoo and conditioner.

Can You Leave This Oil in Hair Overnight?

While you can leave castor oil in your hair overnight, it’s best to do so only occasionally. Leaving any oil on your hair for longer than four hours can lead to the buildup of dead skin cells and debris, potentially causing inflammation.

How Long Does This Oil Take to Work?

Castor oil begins to reduce inflammation and balance microbes within 15 to 30 minutes of use. However, for noticeable hair growth results, it typically takes six to eight weeks of regular use. It is necessary to continue using to maintain the benefits.

In summary, while castor oil can contribute to scalp health and potentially support hair growth, it’s not a miracle cure and requires consistent use alongside other hair care practices for best results.
