Best Castor Oil For Bears

If you take all of the beard growth products out there and multiply them by the popularity of beards and then divide that by organic versus chemical solutions, you’re left with one large math fail and a lot of confused bros. As of late, there has been an increase on the eco-friendly side of the equation – these guys strive to be holistic in every way even the products they buy. As annoying as it is to admit it, these bros may actually be onto something, when it comes to using castor oil for beard growth.



Castor oil in its most basic form is a triglyceride composed of a number of moisture-rich fatty acids derived from the seeds of the Ricinus Communis plant which grows wild in a number of tropical regions (Africa, Indian Subcontinent & the Mediterranean).  The oil has been around for thousands of years – and it’s been used for curing everything from acne to pain.  Although Castor Oil isn’t just good for curing what ails you, it’s also been used for cosmetic reasons for generations such as a way for women to thicken their hair and eyebrows.

This begs the question… is what’s good for the goose, good for the gander? In other words, can the perceived benefits of using castor oil for the hair and eyebrows extend to beard growth? The short answer is yes – the ricinoleic acid found in castor oil has multiple benefits for growing your beard as well as helping you to start the process.



Like so many of the products out there that claim to assist in growing a miraculously thick and luxurious beard, castor oil won’t take you from baby-smooth to lumberjack over the course of one night. No, nothing in life is ever that simple, is it?  Below we’ve listed some of the key benefits you can actually expect from using castor oil for beard growth:



One of the most attractive benefits of castor oil, for beard bros, is that it is known to both stimulate the growth of hair and also to thicken it. Because of its high concentrations of Vitamin E, minerals, proteins, Omega’s 6 and 9 and other beneficial fatty acids, specifically ricinoleic acid, castor oil has a lot to offer in terms of creating a healthy environment for beard growth.  Ricinoleic acid has been linked to not only helping increase hair density as it stimulates the production of prostaglandin E2 but due to its high viscosity and absorbability, the oil can also penetrate each hair strand.



Castor oil’s antibacterial and antifungal properties are also a factor of why it has seen a rise in popularity when it comes to topical treatments. In terms of what this means for beard health or at least the skin beneath them is that Castor oil helps kill bacteria or fungus, the root cause of some types of acne, rashes & other skin infections.



By being emollient-rich and containing certain antioxidants that work to support the keratin in your hair Castor oil has deep conditioning benefits. Castor oil helps make your beard hair stronger, smoother and less frizzy.



Even when we try our best to be earth-conscious, there are a lot of brands out there that fool us with false advertising especially when it comes to personal care products. That’s why, as with everything else, you have to be careful with the Castor Oil you choose to purchase. You’ll find that some brands use castor seeds that have been sprayed with harsh pesticides or go through chemical refining resulting in a substandard end-product.  Jamaican Black Castor Oil, on the other hand, is known for being processed in a sustainable fashion helping it maintain a high nutrient profile. This type of castor oil often has a dark color and a distinct, smoky scent that tends to be a bit thicker in viscosity than the regular variant.




Unlike traditional beard oils that are used in the day, Castor oil is generally applied as a leave-on deep conditioning treatment at night for beards. If you’re not familiar or need a refresher here is a step-by-step guide to incorporating castor oil into your beard grooming routine:

  1. Before bed, wash your face with warm water and your regular face wash.
  2. Apply a penny-sized amount of castor oil to the palm of your hand. Rub the castor oil between your palms.
  3. Using gentle, circular motions, massage the castor oil into your still damp beard.
  4. Continue massaging for 3 to 5 minutes in order to stimulate blood circulation to the hair follicles. If you’ve got a long beard already, rub some castor oil towards the tip of your beard in order to help with dryness and split ends.
  5. Leave the oil in overnight and wash it off the following morning using cold water.
  6. Do this anywhere from 2-5 times a week before going to bed to achieve best results.



  • If you don’t have a beard but are hoping to grow one with the help of castor oil, use half the amount of what’s suggested above and follow the same routine.
  • Just as a note, castor oil has a tendency to stain. You may want to consider wearing old pyjamas and using pillowcases or sheets that aren’t expensive because it may leave marks.
  • If you aren’t a fan of beard conditioning products, in general, consider applying Castor Oil to only the tips of your beard.



Although one of the best ways to ensure that you’ll receive a sustainable and healthily processed formula is to purchase the Jamaican Black variant, normal Castor oil that is cold-pressed in a hexane-free environment is also a good choice.

While castor oil has a number of benefits for facial hair health, manageability and growth, you may be considering using a beard oil in the day either to use alone or to accompany your nightly Castor oil treatments. There are a number of beard oils out there that are formulated with ingredients that will among other things help boost hydration levels and stimulate hair growth in general. Some of the key oils you should be looking for in blended formulas include:
