Learn the best hair oiling methods that actually work for your specific hair type. From fine hair to coily textures, discover which oils work and how to apply them properly.
Hair oiling is all over your feed: waist-length hair, overnight coconut oil, glossy before-and-afters. Then you try it once and wake up with hair that looks like it hasn't been washed in a week.
Most oiling advice treats every head of hair the same. Fine, straight hair and thick, coily hair need different oils, different amounts and different places to put them. Get the match wrong and you get greasy roots and limp lengths. Get it right and your hair breaks less, because oil cuts down the friction and swelling that wear strands out.
Fine and Straight Hair: Light Oils, Ends Only
Fine hair gets weighed down fast. A heavy oil like castor, or a generous amount of coconut, will leave it flat within hours.
Lighter oils such as argan, jojoba or grapeseed are easier to manage. Keep them on your mid-lengths and ends, away from your roots and scalp, which already make plenty of their own oil. It's the same logic dermatologists use for conditioner: the American Academy of Dermatology suggests fine or straight hair gets it on the ends only.
Amount matters more than which oil you pick. Start with a few drops for shoulder-length hair, warm them between your palms and press them into damp hair before you dry it. If it looks flat afterwards, use less next time.
Thick and Coarse Hair: Where Coconut Oil Earns Its Reputation
Thick, coarse hair can take more oil without looking greasy, and it tends to dry out faster.
Coconut oil has the best evidence behind it. In a 2003 lab study on hair tresses, it was the only one of three oils that reduced protein loss from both damaged and undamaged hair, whether it went on before or after washing. Sunflower and mineral oil didn't. The researchers put this down to coconut oil's small, straight molecules, which can get inside the hair shaft, though this was cut hair in a lab rather than hair on people's heads.
Olive and avocado oil also suit thick hair, but they take more washing out, so use them before you shampoo. Work the oil through damp lengths and ends, and only add it to your scalp if yours doesn't get oily or build up. Leave it on for half an hour, or overnight if your hair is very dry.
Curly and Coily Hair: Sealing and Protection
Every bend in a curly or coily strand is a spot where it can break. The oil your scalp makes also struggles to travel down a strand that coils away from your head, so the ends stay dry.
This is where the LOC method comes in: leave-in conditioner, then oil, then a cream or butter. The leave-in brings the water, and the oil and cream on top slow down how fast it escapes.
Jojoba, sweet almond and argan oil all work for this. Castor oil is thick and sticky, so save it for dry, damaged ends rather than your whole head.
Keep your scalp oiling and massage to the scalp itself, and oil everything else from mid-length down. Your roots stay clean and the fragile lengths still get covered.
Pre-Shampoo vs. Leave-In: Two Hair Oiling Methods
Pre-shampoo oiling suits most people, especially if your hair is fine or your scalp gets oily. Put the oil on anywhere from 30 minutes to a couple of hours before you wash, and you get the protection without the buildup. There's a reason it works: a 2015 review of hair cosmetics explains that oils which get into the hair reduce how much water it absorbs, so it swells and dries less each time you wash.
Leave-in oiling is for very dry, damaged or chemically processed hair. Even then, use a tiny amount and keep it to the ends.
How much oil you can get away with depends on your scalp health. If you deal with dandruff or buildup, stick to pre-shampoo treatments on your lengths and keep oil off your scalp.
Common Oiling Mistakes
Too much oil is the big one. More doesn't mean better, just hair that looks dirty and a scalp that needs extra washing.
Dripping-wet hair spreads oil thinly and unevenly, so towel-dry until it's damp first.
Mixing four oils for their combined benefits usually gives you a heavy blend that's hard to wash out. Pick one that suits your hair, use it for a few weeks and judge from there.
FAQ
How often should I oil my hair for best results?
Fine hair: once a week at most, as a pre-shampoo treatment. Thick or coily hair: 2 to 3 times a week, before washing or as a leave-in, depending on how quickly your hair soaks it up.
What's the best way to remove hair oil without over-washing?
Work shampoo into the oiled hair before you wet it, then rinse and shampoo once more. Condition as normal.
Can oiling my scalp actually help with hair growth?
There's no good evidence that it does. Oil can help a dry scalp and protects your lengths from breaking, so you may keep more length, but it won't change the genetics or hormones that set how fast your hair grows.
