What is Castor Oil? Can I Make it at Home?
Castor oil is a vegetable oil pressed from the leaves and beans of the castor bean plant. The hulls of the castor bean contain ricin and must be removed before processing. Do not try to make castor oil at home.
Properly made, castor oil is safe and has many uses. My article focuses on its use as a hair tonic to stimulate hair growth and promote thicker, healthier eyebrows and eyelashes. It helps eyebrows grow in thicker and darker.
What Causes Thinning Brows?
There are many causes of thinning brows, but these are the main ones:
Why is Castor Oil Beneficial for Hair Regrowth?
Castor oil benefits the hair and skin in numerous ways. The healthy fatty acids found in castor oil can penetrate skin and hair follicles, stimulating the growth of thicker, darker, and healthier hair. Essential fatty acids also nourish the hair and prevent further loss.
How Does Castor Oil Work?
Castor oil penetrates the hair and skin to help eyebrow regrowth.
How to Apply Castor Oil for Eyebrow Regrowth
Applying castor oil is quick and easy. Wash your eyebrows with mild soap or a facial cleanser. Rinse and pat dry. Pour a small amount of castor oil into a shallow dish or the jar cap. Dip a cotton swab into the castor oil.
Tap the swab against the dish or cap to wipe away excess oil. Wipe the cotton swab along your eyebrow, following the natural line of hair growth. Use your fingertips to massage the oil into the skin.Blot your eyebrow with a tissue to remove excess oil.
Leave castor oil on overnight; longer is better. Wash castor oil away in the morning with a mild soap or cleanser. Repeat the process every night for the best results.
Is Castor Oil Beneficial for Itchy Eyebrows?
Depending on the reasons for your itchiness, castor oil may be beneficial. Castor oil is known to be beneficial for skin conditions such as eczema which cause itchiness and for general dryness.
Try using castor oil regularly on itchy skin and eyebrows. The fatty acids lubricate the skin and relieve dry, itchy skin.
Kinds of Castor Oil
Of course, you will also have your choice of organic or non-organic oil, and 100% castor oil versus oil blends. We’ll talk about these later.
Jamaican Black Castor Oil
Jamaican black castor oil is the dark-colored oil extracted from roasted castor beans. The color comes from the ash of the roasted beans. The oil contains products produced from the ash and during the roasting process.
Like regular castor oil, Jamaican black castor oil is rich in fatty acids and phytochemicals which nourish the hair and skin.
Jamaican black castor oil has the same beneficial properties for hair and skin as cold-pressed castor oil. The only difference is the color and processing. The darker color may also provide some staining which makes the eyebrows appear darker immediately.
Applied daily, castor oil will help you regrow thicker and darker eyebrows. It will take time; however. In most cases, you start to see results within 5 to 6 weeks. Castor oil is one of the best hair growth serums available to help your brow and lashes grow thicker and faster.
Is Castor Oil Right for Me?
Castor oil can help almost everyone regrow their brows to some degree. However, if you are wondering if castor oil will work for you, ask yourself these questions. If you answer yes to any of these, castor oil can help.
Is Castor Oil Good for Eyebrows and Eyelashes?
One of the most questions asked regarding this topic is what is castor oil good for? It removes pimples, works as a deep skin cleanser, and reduces swelling and inflammation. And yes, castor oil is good for the hair, hair follicles, and skin surrounding the eyes. If you are using castor oil to increase eyelash growth, be careful.
Apply the oil carefully from beneath the eye and avoid getting it in the eye. Castor oil can irritate the eye, causing redness and pain.
Safety Concerns when Using Castor Oil
Most everyone will see favorable results if they consistently use castor oil nightly. However, it is always possible that you might be allergic to castor oil. If you have any redness, rash, or a reaction of any kind, wash the oil off and stop using castor oil immediately.
Pregnant women and women who are breastfeeding also should avoid using castor oil. Its safety for pregnant women and infants has not been studied.
Care should be taken to keep the oil out of the eyes. Contact with the eyes can cause eye irritation and redness.
How to Find a Good Quality Castor Oil
For best results, you want a high-quality, pure castor oil that is hexane free. While it is not necessary to purchase organic oil, most consumers prefer it. You want to know that you are using a healthy oil that won’t cause other problems in the future.
Additionally, look for 100% pure castor oil. If the oil is not labeled as 100% pure, it has probably been cut with a carrier oil and is not 100% pure. While a lesser grade oil may be beneficial, you need pure oil to get the best results.
Why Use Cold-Pressed Castor Oil?
Cold pressed castor oil is pure castor oil pressed from the leaves and seeds of the castor bean plant. Some oil extraction processes go further and extract the oils left behind with solvents.
While solvent extraction produces a cheaper oil, traces of the solvent may remain in the oil. By choosing 100% cold-pressed castor oil, you are avoiding these traces of solvent that could be harmful.
Best Rated Castor Oil for Eyebrow Growth
Most brands of castor oil will be beneficial for regrowing your eyebrow hair. However, some brands are purer and may work better than lower grade castor oil. The brands listed here are rated highest by consumers and should be easy to find at a health food store.
Beneficial Ingredients in Castor Oil
Castor oil is high in ricinoleic acid which is an effective anti-bacterial and anti-fungal agent. This is an additional benefit to those whose hair loss might have been caused by one of these infections.
It is also high in omega-9 and other fatty acids which nourish the hair, hair follicle, and surrounding skin. It penetrates the skin and delivers helpful fatty acids deep in the pores and follicles
Should I Drink Castor Oil?
No, use castor oil topically on the eyebrow and skin to stimulate hair growth from the outside. Castor oil is a powerful laxative and not to be taken without a doctor’s advice.
I hope I have answered all of your questions about using castor oil for eyebrows and eyelashes. With consistent use, your hair will grow thicker and darker over time.
