Castor oil has been treasured for centuries as a natural remedy, best known for its laxative properties—but its real magic happens when used topically at night. Applying castor oil before bed can unlock a wide range of health and beauty benefits, many of which are often overlooked.
Here are six ways this age-old oil can enhance your nighttime routine:
1. Deeply Hydrates and Restores Skin
Castor oil is rich in ricinoleic acid and vitamin E, making it an excellent overnight moisturizer. Applying a few drops to your face or dry patches before sleep allows the oil to work its way deep into the skin, helping to soften rough areas, fade minor scars, and restore your natural glow while you rest.
2. Enhances Eyebrow and Eyelash Thickness
Looking for fuller brows or longer lashes without expensive serums? Gently brushing castor oil onto your eyebrows and lash line each night may help encourage growth by nourishing the follicles and improving hair resilience.
Tip: Use a clean spoolie or cotton swab to apply a thin layer, avoiding contact with your eyes.
3. Eases Joint Discomfort
Thanks to its natural anti-inflammatory compounds, castor oil can be massaged into sore joints or stiff muscles before bed. When applied to areas like the knees, wrists, or lower back, it can help reduce tension and make your mornings more comfortable.
To boost its effect, cover the area with a warm cloth after applying.
4. Gently Supports Digestion
When taken internally in small, appropriate amounts (and always under medical supervision), castor oil may help relieve occasional constipation by stimulating bowel movement. While not for everyday use, it can be a helpful short-term remedy for sluggish digestion.
Important: Always consult your doctor before ingesting castor oil.
5. Promotes Healthy Hair Growth
Massaging castor oil into the scalp before bed helps nourish the roots and improve circulation. Regular use may strengthen strands, reduce breakage, and stimulate new hair growth over time.
Leave it in overnight and wash it out in the morning with a gentle shampoo.
6. Softens Cuticles and Strengthens Nails
A lesser-known benefit: castor oil works wonders on dry cuticles and brittle nails. Massage a drop into each nail bed before bed, and you’ll wake up with softer skin and stronger nails over time.
How to Use Castor Oil at Night:
- For skin: Massage a few drops into the face or dry areas using circular motions.
- For lashes & brows: Apply a thin coat with a clean brush or swab.
- For scalp: Work oil into the roots and leave overnight.
- For joints: Rub gently into sore areas and cover with warmth.
- For cuticles: Dab a small amount onto nails and surrounding skin.
Be sure to use only 100% pure, cold-pressed castor oil. Perform a patch test before using on sensitive skin, and always speak with a healthcare provider before ingesting it.
