When it comes to our eyebrows, it seems that bigger is better. Blame the beautiful Cara Delevigne – we have some serious eyebrow envy! If your eyebrows are naturally thin on the ground (or maybe you’ve been a bit trigger happy with the tweezers), getting that full-brow look can be a challenge without some make-up magic. Could Shavata Brow Strengthener give sparse brows the boost they need?

The Claims

Consisting of purely castor seed oil, this product aims to thicken over-plucked eyebrows by penetrating the skin and stimulating the hairs to grow at the root. Made up of just one ingredient, we’re intrigued to see if the science behind Shavata can deliver!

The Science behind the Bottle

Castor seed oil broken down into its compounds:

Linolenic acid and Linoleic acid

Linolenic and linoleic acid are probably more familiar to you as fatty acids omega-3 and omega-6. We have found some evidence that they are both absorbed into the skin through the hair follicle, placing them exactly where they could exert an effect – yet there is little research to show if they do! One study indicates that topical linolenic acid can induce hair growth by promoting the anagen phase of the follicle, the phase where the hair fibre is growing, but being sceptical Geeks we’d like to see much more data before we can praise this ingredient as a hero for hair growth.

Ricinoleic acid

Ricinoleic acid has very recently been linked to improving hair growth by blocking the action of prostaglandins; molecules that have been said to accelerate hair loss. This was discovered through a computer modelling study, which recommends ricinoleic acid for consideration in a future hair-loss treatment. Virtual studies are all well and good, but we’d love to see some research about how ricinoleic acid drives hair growth in real people too!

The Verdict

Castor oil is commonly used in cosmetics because of its moisturising properties, so if nothing else this product will leave your skin feeling hydrated! There’s some evidence that compounds found in castor oil, such as linoleic acid and linolenic acid, can boost hair growth when consumed in the diet but there is limited evidence to suggest topical application can have the same effect. Nonetheless, there are some very positive reviews and claims of thicker brows after giving this product a whirl. This could just be due to the product build up though and applying a eyebrow wax, cream or pencil on top of this could give the appearance of a fuller brow. Either way, for only £15.00 it might be worth a try, worst-case scenario you’ll have some really hydrated brows!
