Castor Oil for Men | Thicken Hair, Beard and More!

Castor oil is far from being a health and beauty product reserved for women–castor oil for men is multi-functional, treating skin and hair in ways that address the unique needs men have. As a nontoxic, natural oil, it is a great option for treating skin and hair, and it is free of harsh chemicals that might cause damage. And, because it is such a thick, viscous oil a little bit goes a long way, making it a cost-effective option with a long shelf life. Below are just a few of the many uses of castor oil for men.

Use Castor Oil to Thicken Hair

Women know the benefits of castor oil for thick, luxurious hair, but castor oil is great in helping male pattern baldness. Especially in the early stages of hair loss, when the follicle is still producing hair. Because the hair itself is weak, it is important to get to the source–the hair follicle–in order to improve hair growth.

There are many causes of hair loss, like stress and genetics, but the chemical makeup of castor oil helps fight baldness, a receding hairline, and thinning hair.

Increasing circulation is imperative in promoting hair regrowth, and because castor oil is rich in ricinoleic acid, applying and massaging castor oil directly into the scalp helps to improve circulation by improving the mobility of white blood cells.

Castor oil also has antibacterial and antifungal properties, making it a great natural treatment for hair loss caused by fungus or bacteria on the scalp. It cures folliculitis and ringworm, among other bacterial and fungal infections that can temporarily halt hair growth.

The fatty acids and vitamin E present in castor oil also treat and strengthen damaged hair. The result is thicker, fuller hair! 


Try this: Apply a small amount of castor oil (emphasis on small!) to your scalp using either your fingers or a small vial with a dropper. Massage the oil into your scalp until it has absorbed fully into your skin and hair. For best results, leave castor oil treatment on overnight and rinse out in the morning. Wearing a shower cap, saran wrap, or a towel around your head after applying the castor oil will keep the oil in and prevent staining your pillowcase or sheets.

Use Castor Oil to Grow Facial Hair

Likewise, you can use castor oil to grow and thicken facial hair. Ricinoleic acid is proven to increase hair density in lab animals by thickening individual strands of hair, providing a fuller, thicker appearance. There is research to suggest that the same is true with castor oil for men. Some users report hair growing up to 5 times its normal rate.

Try this: Rub a small amount of castor oil into the skin around your beard and/or mustache. Facial hair should absorb most of the castor oil without leaving too much oil behind, since facial hair tends to have a thicker, coarser texture. But, if you feel an uncomfortable, oily residue after massaging it in, feel free to rinse off with warm water. If possible, allow the castor oil to soak into your skin/hair follicles for at least 15-30 minutes before rinsing off.

  • If you are applying the oil and leaving it in your beard/mustache for the day, you may want to consider mixing the castor oil with an essential oil to mask the castor oil’s scent, which some people find unappealing. Consider an essential oil that is known for thickening hair to maximize the treatment, such as lavender, peppermint, or coconut.
  • If you have trouble growing facial hair, applying castor oil can help with that, too! Rub castor oil directly into your skin in the desired locations, such as around your jaw, cheeks, chin, and under your nose. This will help improve circulation and stimulate hair growth.
    • Note: you will not need to use as much oil if you don’t have existing facial hair. Start with a dime-sized amount and increase if more is needed. Remember, a little bit goes a long way!

Use Castor Oil to Cleanse and Moisturize Skin

Castor oil also cleanses, detoxifies, and moisturizes skin. The compound undecylenic acid can disinfect skin and eradicate the bacteria that causes skin problems such as acne.

It can also help exfoliate dead skin cells and other debris that might be clogging pores. This is an easy addition for men to make to their daily routine. Not to mention, it’s a much more skin-friendly acne treatment than benzoyl peroxide, which dries out the skin.

Try this: To cleanse and detoxify, apply a small amount of castor oil to your face and massage the oil in. Wash off with warm, soapy water. This will help prevent and treat acne as well as exfoliate and clear impurities from your pores.

To moisturize, massage castor oil into the skin. Leave it on for at least 15-30 minutes (if not overnight). This will rejuvenate tired, dry skin, improve its appearance, and keep it protected from the elements (especially during cold, dry winters).

The Bottom Line: Castor Oil for Men

Castor oil helps increase circulation to promote hair growth. It also helps thicken the appearance of existing hair by thickening hair that is thinner in diameter. And castor oil can treat certain bacteria and fungi that cause temporary hair loss, as well as acne and clogged pores.

The antifungal and antibacterial properties, plus the ricinoleic acid, undecylenic acid, fatty acids and vitamin E, all make for a very powerful, natural elixir. Castor oil is not just used for women’s cosmetic needs. Castor oil for men is equally compelling and treats a wide variety of men’s needs.
