If you have fine hair that won’t grow, split ends, or thinning strands, you’ve probably heard the buzz about castor oil. This age-old beauty hack has been used for centuries to nourish the scalp, strengthen hair, and enhance shine—but does it actually help with hair growth?
At Verbena, The Salon, we’re all about science-backed solutions and high-quality haircare, so let’s break down the real benefits of castor oil, how to use it, and whether it can truly give you longer, healthier hair.
What Is Castor Oil? How Does It Work?
Castor oil, scientifically known as Ricinus communis, is a nutrient-rich vegetable oil from castor beans. It’s packed with:
🌱 Ricinoleic acid (a fatty acid that hydrates and nourishes)
🌱 Omega 3, 6, & 9 (for scalp health)
🌱 Vitamins & antioxidants (to protect against damage)
While castor oil won’t magically make hair grow overnight, it creates the ideal scalp environment for stronger, healthier growth by increasing circulation and reducing inflammation.
Regular vs. Jamaican Black Castor Oil for Hair Growth
Jamaican Black Castor Oil (JBCO) is made by roasting and boiling castor beans before extracting the oil. This process raises the pH of the oil, making it better at penetrating the hair shaft for deep conditioning and hydration.
The omega-6 and omega-9 fatty acids in JBCO can do wonders for thinning hair. These acids nourish the scalp, strengthen the roots, and support blood flow to the scalp, which, in turn, may stimulate new hair growth.
💡 Pro Tip: If you have thick, coarse, or dry hair, JBCO is your best bet. If your hair is fine or oily, regular cold-pressed castor oil may be better for you.
Benefits of Castor Oil for Hair
So, why are people obsessed with castor oil? Here’s what it can do for your hair:
✅ Nourishes & Strengthens – Packed with fatty acids and vitamins, castor oil deeply hydrates and reduces breakage.
✅ Boosts Scalp Health – Its antimicrobial properties help fight dandruff, irritation, and scalp buildup.
✅ Reduces Hair Thinning – Castor oil supports stronger follicles, reducing shedding and split ends.
✅ Detoxifies & Exfoliates – It gently removes flakes, product buildup, and excess oil for a healthier scalp.
✅ Enhances Product Absorption – Using castor oil before other hair treatments can help your products penetrate more effectively.
💡 Does castor oil stop hair loss? While scientific evidence is limited, castor oil’s antioxidant power can help protect hair from oxidative stress, which has been linked to hair loss.
How to Use Castor Oil for Hair Growth and Thickness
Have you decided to add castor oil to your hair care routine? Follow these steps for the best results:
1️⃣ Choose the Best Castor Oil for Your Hair
Opt for Jamaican Black Castor Oil if your goal is to nourish your scalp. It penetrates deeply and promotes circulation when applied topically.
2️⃣ How to Apply Castor Oil for Hair Growth
🫶 For easier application, you can mix castor oil with a lighter carrier oil. Examples include jojoba and coconut oil.
🫶 Warm it between your palms and massage directly into the scalp for 2-5 minutes.
3️⃣ Work It Through Your Hair
🫶 Apply from roots to ends, focusing on damaged areas.
🫶 Wrap your hair in a high-quality silk cloth to lock in moisture and protect fabrics from staining.
4️⃣ Let It Sit
🕰️ Fine/medium hair → 30 minutes before washing.
🕰️ Thick/coarse hair → Leave overnight for deep conditioning.
5️⃣ Rinse & Wash Thoroughly
🫧 Shampoo twice to remove all residue.
🫧 Follow with a moisturizing conditioner (like Davines NOUNOU Conditioner).
