How Effective is Using Castor Oil for Beard Growth?

There is no doubt that castor oil is beneficial to hair, but perhaps not in the way some people believe.

It’s important to recognize that we cannot “speed up” our hair growth rate. How fast our hair grows, and the length it reaches, plateaus, and sheds at is down to the genetic lottery.

Genetics play perhaps a more significant role for men, as they dictate how fast and how early a man might lose his hair. That said,  pattern baldness can affect both men and women.

Castor Oil for Beard Growth

Castor oil is not a cure-all for this kind of hair loss. It can nourish the hair and scalp, but it simply isn’t powerful enough to override or reverse hormonal or genetic conditions.

However, not All hope is lost.

One 2015 study showed that omega-6 , combined with omega-3 fatty acids in the diet have also been found to reduce the presence of telogen (shedding) hairs and increase the presence of anagen (growing) hairs.

The key phrase here is ‘in the diet’ – supplements might actually yield better results than applying oil.

But supplementing and boosting an omega-rich diet with External application of fatty acids is important, as our bodies need a extra help to deliver nutrients to the outermost reaches of our skin.

Castor seed is very rich in omega-6 and omega-9 (ricinoleic) fatty acids. So applying castor oil in combination with a diet rich in plant oils, nuts and seeds – you’ll have your best shot at prolific and luscious hair growth.

Most promisingly, omega-9 is linked to PGD2 and PGE2 – naturally occurring substances in the body.

  • PGD2 is thought to shrink hair follicles, preventing hair loss
  • PGE2 is an anti-inflammatory that contributes to hair density.

Bossman’s Castor Oil is the best beard growth oil brand with excellent source of omega 6 + 9.

Active Compounds & Properties of Castor Oil

Let’s take a look at what nutrients and compounds are present in this magical castor oil below….

Ricinoleic acid: A high concentration of ricinoleic acid is found in castor oil. The suffix ‘oleic’ in an ingredient name tells us that it’s a fatty acid – in this case, an omega-9 unsaturated fatty acid.

Omega 6 + 9 Fatty Acids: Castor oil contains essential fatty acids are the building blocks of healthy cells. They form the skin’s natural barrier, and act as humectants that aid the skin to draw in moisture from the air.

Vitamin E: One of the most important vitamins for hair and skin health, vitamin E plays a crucial role in nourishing, protecting and healing the scalp and hair follicles.

Triglycerides: Castor oil contains triglycerides which help to remove dirt from the skin, and maintain moisture.

The 3 anti’s: Castor oil is anti-inflammatory, anti-fungal, and anti-microbial.

Antioxidants: Antioxidants fight free radicals. The unstable oxygen particles in the atmosphere that cause skin, hair and follicle cells to break down, otherwise known as ‘oxidative stress’.

Benefits of Using Castor Oil for Beard

Beards are where castor oil really (literally) shines.

Bacteria and fungal cells on the skin or scalp are enemies of prolific hair growth. They are common problems for beard-growers, especially if facial hair is particularly dense.

The most important thing castor oil can help with is to clear the way of anything that might inhibit growth.

In the same way that trimming hair on your head helps it to “grow” by preventing split ends from destroying the length, the anti-fungal and anti-microbial properties of castor oil treat harmful bacteria on the surface of the skin. This will remove the bacteria that is blocking or harming the follicle.

Returning again to the hair example, hair on your head cannot grow long and strong without adequate moisture. Without moisture, it will become brittle and break before it can reach any substantial length.

Beard hair does tend to be stronger and coarser, but it still benefits hugely from the nourishing vitamins and fatty acids found in castor oil.  They have the power of rebuilding and maintaining the moisture barrier that protects your facial hair from external damage.

The proof will be in the noticeable shine and softness, and decreased “bristliness”, of your beard hair.

Adequate moisturizing of the skin underneath your beard also prevents it from drying and flaking, preventing dead skin cells getting trapped under the facial hair. As a result, castor oil protects and promotes your beard growth by keeping adequate moisture within your hair follicles. 

Finally, applying a light coat of castor oil to a long beard (or mustache) can act as a holding balm. It allows you to create styles and braids, or simply to smooth down stray hairs and flyaways.

1.Will castor oil make my skin oily?

A common concern when integrating oils into a skincare regime is if it will make the skin more oily. But in fact, the opposite is true.

Most plant-based oils are non-comedogenic (meaning they don’t clog pores), anti-bacterial, and light enough to nourish without overloading the skin.

For example, Castor oil has a comedogenic scale of 1 out of 5. It means castor oil will highly unlikely to clog your pores. Some (like tea tree, rosemary and ylang ylang) are even recommended for balancing oily complexions.  

2. How much castor oil should I apply?

With castor oil, a little goes a long way. Start with 2-3 drops rubbed between your palms and smooth it on. It’s beneficial to create a little bit of contact with the skin so your hair follicle will absorb the nutrients too. If your beard is particularly thick or long, add another couple of drops.

3. When should I apply or use castor oil?

Use castor oil for beard after showering is ideal. Your pores and follicles will be open, ready for maximum nourishment and absorption. You can apply it any time of night or day.

5. Beard oil vs Beard balm – What is better?

Beard oil is designed for short to medium length beard. It is in liquid form at room temperature. Mixture of natural oils such as castor oil, coconut oil, jojoba oil, castor oil, grapeseed oil, sunflower seed oil etc, are the main ingredients. The purpose of using oil for beard, is to nourish and moisture your beard. Some beard oil with castor oil can assist in promoting beard growth. Beards oil with lemongrass, eucalyptus, and peppermint oil have antifungal + antibacterial properties.

Beard balm is designed for medium to long length beard. It is in wax or soft solid form at room temperature. Most men use beard balm mainly for holding or styling. It also functions as a leave-in conditioner that that moisturizes, nourishes and soothes your beard. Most of the beard balm in the market are made of shea butter and beewax as a base, plus a carrier oil (such as almond oil), plus 1-2 essential oils which gives the scents.

6. Does Jamaican black castor oil works better than regular castor oil?

The main difference between the 2 oils is the way they were extracted. Regular castor oil is generally cold pressed and it is generally pale yellow to light green in color. On the other hand, Jamaican black castor oil is generally roasted to produce a darker color. The darker color is actually caused by ash from roasting. Users reported that both regular castor oil and Jamaican black castor oil have similar effectiveness in promoting beard growth or hair growth.
