Can castor oil really make your hair grow?
November 9th 2018 / 0 comment
Castor oil: it’s the all-natural remedy that’s received glowing testimonials across the web for its hair growth potential - but is it really the secret to a fuller lash and hair line? We found out
There are certain all-natural remedies that have stood the test of time - coconut oil, apple cider vinegar, rosemary...it reads like a shopping list at Whole Foods. However, there’s one that a growing number of people swear by for meeting their hair care needs - castor oil, the golden (or dark brown) elixir that, if the glowing testimonials on blogs and Reddit are to be believed, holds the key to a fuller head of hair and a thicker lash line too.
Castor oil benefits for hair
There are two types best known for their root-boosting benefits - castor oil which is golden in colour and black castor oil, which is made from roasted castor seeds and is said to be more clarifying due to its more alkaline make-up. Both are quite heavy in feel and texture which can be a little off-putting, but they make up for that with their impressive vitamin E and fatty acid content. “Castor oil is rich in ricinoleic acid which has anti-inflammatory, anti-fungal and anti-bacterial properties,” Guy Parsons, certified trichologist and founder of My Hair Doctor tells me - the perfect scalp-calming combo.
Does it work for eyebrows and eyelashes?
Its ricinoleic acid content can also keep brows and lashes healthy too. “It’s great for combating damaged lashes and keeping them moisturised and conditioned,” says Jaimineey Patel, Head of Training at Blink Brow Bar. It’s especially handy if treatments such as tints and lash extensions have left them dry and split.
Can it actually make your hair grow?
Another key benefit of castor oil is its ability to increase blood flow around the scalp, which is why many people believe that it can increase hair growth. There needs to be more evidence though, says Guy, to show a direct connection: “There is no link between follicular hair growth and castor oil, and any suggestion otherwise is anecdotal.” Considering how complex the reasons for hair loss and thinning hair can be, this makes perfect sense.
That’s not to say though that castor oil isn’t worth incorporating into your regime. If used properly, it can improve the condition and flexibility of your strands, to prevent them from snapping off due to dryness. “Being an oil, it will have clear moisture and replenishment benefits for thicker, coarser hair that requires more moisture than other hair types,” says Guy.
Its viscosity actually works in its favour in these cases notes Gemma Hume, Afro Specialist at Paul Edmonds London. “Castor oil is naturally thicker in consistency so it’s great for coating curly and Afro hair and sinking right down to the roots,” she tells me. “Always apply it to the scalp, massaging it in, and leave it on the hair with a plastic cap, under heat, for 30 minutes to intensify the penetration of the oil.”
How much to use
As mentioned earlier, castor oil’s much richer than other oils and, unless you have Afro, thick or curly hair, using it neat can actually end up being counterproductive. “Use it in a diluted form, as it may be very difficult to remove and any benefit from the oil will be undone by the six times you need to wash your hair to get it out!” cautions Guy. Good point.
If you’re using it as a scalp or moisture treatment, he recommends diluting it so that it’s one part castor oil, five parts almond or argan oil (which are both lighter). Apply sparsely to start with - if you have hair that gets greasy quickly, just apply it to mid-lengths and ends (hair’s more damaged towards the ends anyway) and avoid using it in conjunction with other moisturising products to prevent a case of ‘over-hydration’. If greasiness fears are still weighing on your mind, look for it as a core ingredient in your hair care products instead (such as those in our edit below).
The same approach applies to its use on eyebrows and eyelashes too. While castor oil won’t necessarily help them grow quicker, incorporating products that have the ingredient in them into your nightly regime can certainly go some way in making them stronger and less prone to breakage. “It’s best when combined with other ingredients,” says Jaimineey. “For example, our BBB London Luscious Lash Oil contains seven essential oils, all of which work in harmony to grow, stimulate and hydrate lashes.”
You could use castor oil neat, but it won’t feel all that comfortable and you might run the risk of causing irritation if you do happen to overdo it on the application.
The bottom line
Castor oil won’t boost your hair’s growth from the follicle, but it can improve the condition of your hair so that it doesn’t break off before reaching a certain length. It can help boost scalp health by increasing circulation, but due to its stickiness, the majority of hair types could benefit from using it in a product that combines it with other ingredients, rather than using it neat.
