Recently, my mother stopped over my place with Couture Colour Pequi Oil Treatment.
“You have to try this!” she gushed. “Everybody on TV is raving about it!”
“But I’m already using argan oil,” I informed her. “I can’t use them both at the same time, or my hair will be like an oil slick!”
Well, one woman’s plight is about to become others’ reason for enlightenment, at least when it comes to hair oil, because I just had to know: What should I be using? What is the best hair oil?!
Argan Oil: Best for Flat or Straight Hair, UV Protection (for Now)
Pequi Oil: Best Before a Date (Incredible Scent!), Best for Curly, Frizzy, or Very Dry/Brittle Hair
Also known as Caryocar brasiliense fruit, pequi is an edible fruit popular in the central-west portions of Brazil. For centuries, the yellow-orange fruit has been used in popular meals and recipes, such as chicken with rice. However, after a 2009 study in Genetics and Molecular Research found that pequi oil consumption was a significant enough antioxidant to lessen DNA damage in runners, interest started to in pequi started to pique.
While research on pequi oil is still limited, in addition to being a potent antioxidant, it has been found to be a source of lipid-rich hydrating agents in the Journal of Science of Food and Agriculture. Pequi oil is actually comprised of numerous other oils, including olive oil chief component oleic (55%), palmitic (34%), heptadecenoic (5%), and linoleic (2%), amongst others, according to the International Journal of Food Properties. Note that argan oil conversely contains mostly linoleic and oleic acid, a chief difference between the two.
From personal use, pequi oil has the best scent of any of the other oils we have tested. I describe it jokingly as the scent of a “romantic nut” – it’s sweet and almond-like, with a hint of something deeper and sultry, like amber. I thought I was nutty (ha) for having this assessment, but research has actually been published in the Journal of Food Composition and Analysis on the complexity of notes in pequi oil.
Although I cannot find research to substantiate this yet, it seems to me that pequi oil is better for frizzy, dry, or brittle hair than argan oil. Pequi oil [with mostly oleic acid] feels a bit heavier on the hair than argan oil [with mostly linoleic acid], and this makes sense, given that oleic acid is heavier than linoleic acid (282 g/mol versus 280 g/mol). Pequi oil is therefore also more likely to flatten the cuticle, making curly or frizzy hair reflect the light somewhat better. After testing it, although there were no scientific conditions and a very small sample size, we agreed with our hypothesis: argan oil for straight hair, pequi oil for curly.
Bottom Line: Both Great Oils for the Hair
The bottom line is that it seems argan oil is best for those with straight, thin, or flat hair, owing to its high lightweight linoleic acid content. On the other hand, pequi oil seems better for those with curly, frizzy, or very brittle hair, owing to its high concentration of slightly higher-weight oleic acid.
Both oils are likely to impart softness, shine, and UV protection to the hair. My best recommendations from each group include Josie Maran Argan Oil and Couture Colour Pequi Oil Treatment. I’m currently using Josie Maran Argan Oil on my hair during the day and Couture Colour Pequi Oil Treatment before I go out with my boyfriend (I told you, it smells a-maz-ing!)
