You notice it first on a dark jumper. Then in the shower, when the water hits and your scalp stings faintly at the hairline. A scalp oiling routine for a dry, itchy scalp is not a complicated thing, and it is one of the oldest answers we have to this particular discomfort, but almost everyone I speak to is doing at least one part of it in a way that makes it less effective than it could be.
So here is how I do it, and why each part is there.
First, work out what is actually happening up there
Dry scalp and dandruff are not the same problem, and oil is not the answer to both.
The American Academy of Dermatology draws the line clearly: dry scalp happens when the skin loses too much water, often from harsh products or weather, and generally responds to switching to a gentle, non-medicated shampoo. Dandruff is a different mechanism, associated with yeast, and wants a dandruff shampoo instead. The Academy also notes that persistent flaking can be psoriasis, a fungal infection, or in older adults with thinning hair, sun damage that needs looking at.
So the honest version of this article begins with a caveat. If your scalp has been flaking, itching or sore for weeks, if there are defined patches, silvery scale, or any hair loss in the affected area, see a board-certified dermatologist before you reach for a bottle of oil. Oiling is lovely for a scalp that is simply dry. It is not a treatment for a condition, and I would rather you got the right help.
Assuming what you have is ordinary winter dryness, harsh-shampoo dryness, or the tight, papery feeling that comes with too much dry indoor heat, read on.
Choosing an oil
Almost any well-made plant oil will do the physical job of reducing water loss from the skin surface. Where the choice starts to matter is texture, absorption and how the smell makes you feel, which is not a trivial consideration when you are going to be wearing it for an hour.
- Lighter oils such as jojoba and grapeseed sit close to the skin, absorb reasonably quickly and wash out with one round of shampoo. Best if your hair is fine or you oil frequently.
- Heavier oils such as coconut and castor stay on the surface longer and are more occlusive. More effective for very dry skin, considerably harder to remove.
- Infused botanical oils carry plant material steeped into a carrier oil. The scent is softer and rounder than essential oil dropped into a base, and it fades rather than announcing itself.
The botanical infused oil I pair with the copper and wood scalp comb comes in nine scents for exactly this reason. Lavender Calm and Chamomile Dream for the evening, Rosemary Vitality and Peppermint Refresh when you want the routine to wake you up rather than settle you. It is a one ounce bottle, which sounds small until you realise how little you actually need.
If you are new to plant oils generally, I have written more about how they behave on skin and hair in the wider botanic body and glow rituals range.
The scalp oiling routine, step by step
Do this on dry, unwashed hair, on a day when you are going to wash it anyway. Trying to oil freshly clean hair and then not wash it is how people end up disliking the whole practice.
Warm the oil slightly. Pour what you need into a small dish and stand it in a mug of hot water for a minute. Warm oil spreads further, absorbs better, and is far more pleasant. Do not microwave it.
Use less than you think. A teaspoon for short hair, two for long. You are oiling the scalp, not the hair. Excess on the lengths just makes the wash-out harder.
Part and apply. Make a parting, drip a little oil along the exposed scalp, then make the next parting an inch over and repeat. Work across the whole head. This takes four or five minutes and it is worth doing properly, because oil poured on top of hair mostly never reaches the skin.
Massage it in. Fingertips first, small circles, moving the skin rather than sliding over it. Then go over the whole scalp with a comb. A wooden scalp ritual comb is better than a plastic one here, because wood does not build static and the blunt, rounded teeth distribute oil evenly without catching. Five minutes, unhurried.
Leave it, then wash. Somewhere between thirty minutes and a couple of hours. There is no strong evidence that overnight is better, and sleeping in oil means pillowcases and, for some people, congested skin along the hairline. An hour with a towel over your shoulders while you do something else is plenty.
Washing it out without stripping everything you just did
This is the step people get wrong, and it is why some come away convinced oiling made things worse.
Apply shampoo to dry, oiled hair before you wet it. Shampoo needs to bind to the oil, and if you soak your head first the water gets in the way and you end up washing three times with an increasingly aggressive hand. Work the shampoo through dry, then add water gradually and it will lift in one round.
Use a gentle, non-medicated shampoo, which is what the Academy of Dermatology recommends for dry scalp in the first place. Finish with cooler water than feels natural. And resist the urge to scrub with your nails, however satisfying it is. Scratching an itchy scalp reliably makes the itch worse, and can break skin that is already compromised.
How often, and what about seasonal shedding
Once a week suits most people. Twice if your scalp is very dry or the weather has turned. Less if your hair is fine and goes flat easily.
Every autumn I get messages from people alarmed by how much hair is coming out in the comb, wondering whether oiling will stop it. Two honest things about that. First, the American Academy of Dermatology notes that shedding fifty to a hundred hairs a day is normal, and that excessive shedding, telogen effluvium, is usually temporary and follows a trigger such as illness, significant stress, surgery or childbirth, typically peaking around four months afterwards and settling within six to nine months. Second, no oil and no comb will change that cycle, and I will not pretend otherwise.
What oiling does is reduce the mechanical friction of combing and make a dry scalp more comfortable. If shedding is heavy or prolonged, that is a conversation for a dermatologist.
None of the products I make or carry are intended to diagnose, treat, cure or prevent any condition. They are for comfort, and for the small ceremony of taking care of yourself.
Why the slowness is the point
I could tell you to do all of this in three minutes and you probably could. But the reason this practice has survived for centuries across so many cultures is not only the oil. It is the twenty minutes of sitting with warm oil on your head, doing nothing else, that people come back for.
Sunday afternoon, in my case. Oil warmed in a mug, comb, an hour, then a wash. It is the most reliably restorative thing in my week and it costs almost nothing.
If you want to build the tools out, the Ayurvedic massage tools collection has the combs and body tools I use. Start with an oil and one comb, though. That is a complete routine on its own.
Frequently asked questions
How long should I leave oil on my scalp?
Thirty minutes to two hours is a sensible range. Longer does not appear to add much, and overnight oiling means oily pillowcases and, for some people, breakouts along the hairline. If you enjoy sleeping in it, use a towel on the pillow and a lighter oil.
Can scalp oiling cause more dandruff?
It can seem to. Dandruff is associated with yeast that feeds on oils on the scalp, so if your flaking is dandruff rather than simple dryness, heavy oiling may not help and a dandruff shampoo is the recommended route. Work out which one you have first.
How often should I oil my scalp?
Once a week is a good default. Increase to twice in cold, dry weather or if your scalp feels tight. Reduce if your hair goes limp or your hairline congests.
Should I oil before or after washing my hair?
Before. Oil goes onto dry, unwashed hair and is washed out afterwards. A very small amount of oil on the mid-lengths and ends after washing is a different thing, and fine, but it is not scalp oiling.
Do I need a comb, or are fingers enough?
Fingers are enough to apply and massage. A wide-toothed wooden comb distributes the oil more evenly across the whole scalp and lets you keep going longer without your hands tiring. It is an improvement rather than a requirement.
My scalp is itchy and flaking. Will oiling fix it?
If it is straightforward dryness, oiling and a gentler shampoo often help. If the itching has lasted weeks, if there are defined patches or silvery scale, if it is painful, or if hair is thinning in the same area, see a board-certified dermatologist. There are several causes of scalp itch that need prescription treatment, and oil will not address any of them.
