For many of us, putting oil on our hair makes no sense whatsoever. They're greasy, aren't they?
Not if you choose the right one.
As most hairdressers will tell you, oils are the secret to healthy, frizz-free locks - especially during the winter months when we're more prone to suffering from a few bad hair days.
"Oils have amazing benefits on the hair and skin," celebrity hairstylist Julien Farel told us. "I have always recommended natural oils like olive, coconut or almond for a 'hair detox' when your hair is feeling dry. It will make your hair look and feel healthier overall."
Coconut oil and Argan oil are both loved for their hair conditioning properties, but there are some brilliant new products out there to suit all hair types.
"As far as choosing the right oil for you, it's like choosing a shampoo or conditioner," Farel added. "The finer your hair is, the lighter the oil should be."
Ojon's Rare Blend Oil Moisture Therapy - made with Mexican aloe vera, grapeseed oil and malachite water - has been designed to rescue dry, damaged hair types. (It will arrive on shelves in January 2015.)
"Rare Blend Oil is the hair care equivalent of a multitasking BB cream," Lynn Mazzella, the senior vice president of product development at Ojon, says. "It repairs, creates shine, boosts moisture, reduces frizz, detangles and strengthens damaged hair in one step."
Girls with curly hair who want to make their locks more manageable might also want to note Bumble & Bumble's latest launch - the Hairdresser's Invisible Oil. This lightweight formula smoothes and softens in an instant, plus a little goes a long way.
"I work a dime size into dry hair for on-the-spot smoothing and frizz control," Bumble hairdresser Bronwen Melvin says. "This is the hairdresser's shortcut to softness."
And if you're all about sticking to all-natural beauty buys, Susan Curtis, natural health director at Neal's Yard Remedies recommends using coconut oil to make a hair mask.
"Apply a couple of teaspoons to your hair," she told us. "Comb it through and wrap in a towel or turban, or just a shower cap. Leave for an hour or two, at least – or if you are feeling very ambitious leave overnight. Follow with a shampoo as usual - try a gentle, good quality organic product."
