For most people, once a week is a good place to start. Fine or oily hair often does better every one to two weeks, while dry, thick or curly hair usually suits a weekly treatment. Fifteen to thirty minutes before you wash is enough. The right frequency depends on your hair type, your scalp and how your hair feels after washing.
Hair oiling does not need to be complicated. A small amount of the right oil, left on for the right length of time, fits into the wash day you already have.
What follows is the frequency by hair type, how long to leave it on, how much to actually use, and the signs that you have been doing too much of it.
How Often Should You Oil Your Hair?
Start with once a week and watch what your hair does.
Fine hair gets weighed down easily, so every one to two weeks is often enough. Dry, thick or curly hair usually handles a weekly treatment comfortably. If your scalp runs oily, you may want to oil less often, or keep the oil on your lengths and ends and off the roots.
There is no single answer, because texture, scalp oiliness, how often you wash and how much oil you use all pull in different directions. One session a week is simply the easiest place to begin. If your hair feels heavy afterwards, use less or leave a longer gap. If the lengths still feel dry, go up gradually.

These are starting points, not rules. Adjust by how your hair looks and feels after washing rather than by the calendar.
Fine hair
Fine hair goes limp quickly when there is too much oil on it. Start with about a teaspoon, and do not saturate from root to tip.
Every one to two weeks is usually enough, and a shorter treatment of 15 to 30 minutes is easier to manage than leaving oil on for hours. A lighter oil helps: Gya Labs Organic Jojoba Oil, $14.99 for 100ml, is technically a liquid wax rather than an oil, which is why it feels lighter than its price per ml suggests.
Work it through the parts that feel dry, leave it, then shampoo. If your hair looks flat afterwards, use less next time before you change anything else.
Dry, thick or curly hair
This hair handles more oil, and it still does not need a lot. Two to three teaspoons is plenty for most lengths.
A weekly treatment of 30 minutes to an hour is a practical routine. For lengths that look dry, Organic Argan Oil at $16.99 for 100ml is richer than jojoba and works on its own as a pre shampoo treatment.
Applying more than you need makes even dry hair hard to wash cleanly, and that is the most common reason people decide oiling does not work for them.
Oily scalp
If your scalp is oily by day two, scalp oiling may not be the part you need.
Use about a teaspoon on the mid lengths and ends instead of the roots. If you do want to oil the scalp, keep it short and use less than you would for dry hair. Every one to two weeks is a reasonable start and you may find you want it less often than that.
Your washing routine matters here too. If the roots already feel greasy between washes, adding oil mostly adds weight.
How Long to Leave Oil In
Fifteen to thirty minutes is the starting point for a pre shampoo treatment. Dry or thick hair can take 30 minutes to an hour.
You do not need to leave it overnight. A shorter treatment washes out more easily and suits fine hair and oily scalps better.
Overnight oiling
Overnight can be part of a routine for dry, thick or textured hair, and it is not essential for anyone.
Several hours on means more product to remove in the morning, which on fine hair or an oily scalp usually means flat, greasy results and two rounds of shampoo. If you enjoy it and your hair responds well, carry on. There is no reason to stop just because a shorter treatment also works.
How Much Oil Should You Use?
This is the part most guides skip, and it is the one that decides whether the whole thing works.
About a teaspoon for short or fine hair. One to two teaspoons for shoulder length. Two to three for long or thick hair. Measure it the first couple of times rather than pouring into your palm, because a palmful is usually three or four times what you need.
Warm it between your hands, work it through the lengths first, and only go to the scalp if the scalp is what feels dry.
Before or After Washing?
Before, for most people.
Apply to dry hair before shampooing, focus on the lengths and ends or go broader depending on your hair type, leave it for the time above, then wash as usual.
Oiling after washing is a different thing and a much smaller amount. A drop or two through the ends adds softness. More than that on damp hair is how you end up looking like you skipped a wash.
If you are not sure which suits you, start with the pre shampoo version. It is easier to control and the shampoo removes anything you overdid.
Signs You Are Over Oiling
If you have started oiling regularly and your hair looks worse rather than better, the amount or the frequency is usually the reason.
• Hair looks greasy soon after washing
• Hair feels limp or heavy
• Roots get oily faster than they used to
• You have lost your usual volume
• It takes two or three rounds of shampoo to get the oil out
• Your scalp feels coated or uncomfortable
You do not have to stop. Cut the amount first, because that fixes it more often than anything else. Then shorten the treatment. Then leave more days between sessions. A routine you have to fight out of your hair is not a routine you will keep.
Choosing a Lighter or Richer Oil
The oil changes how the whole treatment feels.
For fine hair, lighter is easier. Jojoba is the usual starting point. For dry or thicker hair, argan has a smoother, richer feel and works on its own rather than in a blend of four things. The full range is in the carrier oils collection, and the Hair and Scalp Care range groups them with the rest of what suits a wash day.
Adding an essential oil
Essential oils are not carrier oils and they do not go on the scalp neat. If you want to add Rosemary Essential Oil to a hair blend for the aroma, dilute it to 1 to 2 percent: 2 to 4 drops per 10ml of carrier oil, or 6 to 12 drops per 30ml.
Patch test on the inner forearm and leave it 24 hours before putting a new blend on your scalp. Our step by step guide to diluting essential oils has the ratios for other volumes.
Rosemary is also one to check before you use it. It is commonly cautioned in pregnancy and for anyone with epilepsy or a history of seizures, so ask your doctor or midwife first if either applies to you.
Final Thoughts
There is no single rule for how often to oil your hair. Once a week is a sensible place to start, and the rest is noticing what happens.
Fine hair wants a lighter oil, a teaspoon of it, and a short treatment. Dry, thick or curly hair can take a weekly session, a richer oil and a bit longer. An oily scalp usually wants the oil kept to the lengths.
Use less than you think, leave it on for the time that suits your hair rather than the longest time you can manage, and change one thing at a time when something is not working. That is the whole method.
