Castor oil is a carrier oil extracted from the seeds of ricinus communis, a shrub native to East Africa in the Euphorbiaceae family. It is widely used in cosmetics, as it is considered non-comedogenic, meaning it doesn't clog pores. As a result, it is easily absorbed by the skin. Its active ingredients, including oleic acid, linoleic acid and saturated fatty acids, are beneficial for skin and hair hydration. Whether your beard is rough, patchy or neglected, applying castor oil will revive and moisturise it, and may even help it grow faster.

What is castor oil?
The benefits of castor oil
Moisturises and reduces itching: Shaving disrupts the hydrolipidic film and dries out the epidermis. Castor oil moisturises the skin thanks to its fatty acids.
Softens the hair: Castor oil softens the hair on your head and your beard, leaving it shinier and resulting in a cleaner look.
Stimulates hair growth: Castor oil contains ricinoleic acid, which is known for encouraging hair growth. It moisturises and strengthens your beard.
Protects the skin: While beards can often be itchy when they're not looked after, castor oil and the ricinoleic acid it contains act as antimicrobials and fungicides, reducing itching and the appearance of dandruff.
How many times a week should I use castor oil?
If you have a dry or itchy beard, apply this carrier oil in the morning and evening every day to help moisturise it.
The length of your beard can influence how often you apply it. Long beards will need extra moisture, so use the oil more frequently. However, if you have oily skin, start with a small amount once a day, or every other day, to stop your beard looking greasy.
How long should I leave castor oil on my beard?
For castor oil to work, it needs to be left on for long enough to be absorbed. Apply a small amount of castor oil to your beard and leave it on throughout the day, allowing it to be absorbed by the hair and skin. Or, just as you would with a night mask, apply a generous amount of castor oil to your beard before bed and leave it on overnight. This allows your beard to deeply absorb the oil, leaving it nourished. Wash off any excess carrier oil in the morning.

How do I apply castor oil to my beard?
Clean your beard: before applying the oil, you can use a beard shampoo or mild cleanser to remove dirt, excess oil and other impurities.
Dry gently: gently pat your beard dry with a towel. Don't rub vigorously, as this could irritate the skin.
Prepare the castor oil: pour a few drops of castor oil into the palm of your hand. The amount will depend on the length of your beard, so start with a few drops and add more if necessary.
Distribute the oil in your hands: rub your palms together to distribute the castor oil evenly.
Apply to the beard: slowly massage the oil into the beard, making sure you cover the hair evenly from root to tip. Don't forget to also massage the skin underneath the beard.
Use a comb or brush: for even distribution, comb the beard with a beard comb or brush after applying the oil.
Leave it on: leave the castor oil on for a few hours or overnight.
Wash if necessary: wash it off with a beard shampoo as part of your regular washing routine unless you are leaving it on overnight.
Does castor oil make beards grow?
Castor oil is rich in ricinoleic acid, which has anti-inflammatory properties that promote scalp health. It's widely believed to promote hair grow by stimulating the hair bulb (the hair follicle), and it also moisturises your beard and prevents dryness, which is beneficial for healthy hair growth. However, beard growth depends largely on genetics. If you naturally have sparse facial hair, castor oil is unlikely to change the growth pattern of your beard. Its strengthening properties can however be useful if you have gaps in your beard.
Which oil is good for beards?
Castor oil is not the only oil often used in beard care. You can also use argan oil, which contains vitamin E that helps soften beard hair. Jojoba oil moisturises hair without leaving a greasy residue, thanks to its nourishing qualities. Sweet almond oil promotes healthy hair growth. Hemp oil has also become a miracle product in recent years thanks to the presence of Omega-3 and Omega-6 fatty acids, which strengthen hair and maintain healthy skin.
Minoxidil or castor oil?
Minoxidil is a drug recommended for stimulating hair growth. However, it can dry out the skin, causing irritation and itching. Before using it on your beard, it is important to consult the instructions for use and seek advice from a healthcare professional. Castor oil is a natural option with varying results, but it can strengthen the hair and soften the skin.
