Hair Oil for Men: Which Hair Types Benefit and How to Apply It

Hair oil helps men whose hair is dry, coarse, curly, afro-textured, long or frizz-prone, because it slows moisture loss, smooths the outer layer of the strand and adds a bit of weight and shine. It does little for short, fine or naturally oily hair except make it look flat and greasy. The amount that works is smaller than most men expect: two or three drops for short hair, a few more for longer or coily hair, warmed in the palms and worked through the lengths and ends rather than rubbed into the scalp.

Below: which hair types benefit, which oils behave differently, three ways to use it, and how to tell when you have overdone it.

What hair oil actually does

A strand of hair has an outer layer of overlapping cells called the cuticle. When the cuticle is smooth and flat, hair looks shiny and holds moisture well. When it is lifted, from heat, sun, colour, rough towelling or simply the shape of a tight curl, hair loses water faster, tangles more easily and looks dull or frizzy.

Oil coats the strand and slows that water loss. It also reduces friction between hairs, which means fewer knots and less breakage when you comb. It is not a moisturiser in the sense of adding water. It holds in water that is already there, which is why oil works best on hair that is slightly damp.

What oil does not do: it will not repair split ends, regrow hair or change thickness. If you are worried about thinning, the NHS page on hair loss is a sensible place to start, and a GP is the right person to see.

Which hair types benefit

Hair type	Does oil help?	How to use it
Afro and tightly coiled	Yes, often essential	After a water-based leave-in, to seal
Curly or wavy	Usually	A few drops on damp hair, mainly ends
Thick, coarse, straight	Yes	Lengths, to calm frizz and add shine
Long hair of any type	Yes, on the ends	Last few inches only
Fine or thin	Rarely	One drop on ends if they are dry, or skip
Short back and sides, oily scalp	Usually not	Use a matte product instead

A useful tell is porosity: how quickly your hair absorbs water and product. Hair that drinks product and dries fast usually loves oil. Hair that sits wet for ages and leaves product on the surface needs much less. We explain the test in hair porosity for men.

Not all oils behave the same

• Argan oil. Light to medium, absorbs fairly quickly, good all-rounder for wavy and thick hair.
• Jojoba oil. Technically a liquid wax, light and close in feel to the scalp’s own oil. Good for men who find other oils heavy.
• Coconut oil. Solid when cold, heavier on the hair. Some research suggests it penetrates the strand better than many oils, and it is popular as a pre-wash treatment. Some people find it leaves coarse hair feeling stiff.
• Castor oil. Very thick and sticky. Used in small amounts on afro hair and edges, usually mixed with a lighter oil.
• Silicone-based “hair oils”. Many shop serums are mainly silicones with a little plant oil. They give fast shine and frizz control. Not a problem, but they can build up; see silicones in hair products.

Fragrance and essential oils are common irritants. If your scalp itches or reddens after a new oil, stop using it.

Three ways to use hair oil

1. As a finishing oil (most men)

1. Towel-dry gently so hair is damp, not dripping.
2. Put two or three drops in one palm, rub both palms together.
3. Smooth over the lengths and ends first, then whatever is left over the surface.
4. Style as usual. Add a single extra drop only if it still looks dry once dry.

2. As a sealant for afro and coily hair

Water or a water-based leave-in goes on first, then the oil, then a cream if you use one. The oil’s job is to hold in the moisture, not to replace it. Oil on dry afro hair without water first tends to sit on the surface.

3. As a pre-wash treatment

Work a little oil through dry lengths 20 to 30 minutes before washing. It cushions the hair against shampoo stripping it, which suits dry or long hair. Wash it out thoroughly, sometimes with two rounds of shampoo.

Mistakes that make hair look greasy

• Too much. The most common problem by far. Start with less than you think.
• Applying to the roots. The scalp already makes oil. Roots go flat first.
• Using it on fine, short hair and expecting texture. For that you want clay, paste or powder.
• Layering it under an oil-based pomade, which doubles the weight.
• Never clarifying. Regular oil use plus styling products can build up. A clarifying wash every few weeks helps.
• Using beard oil instead. It can work in a pinch on short hair, but beard oils are often heavier and more scented; we cover that in using beard oil on your hair.

What to ask your barber

Every visit at Highgate Cuts starts with an assessment, where the barber looks at your hair and what you need before recommending anything. That is the moment to ask whether your hair would benefit from oil at all, how much to use for your length, and where to put it. On coarse or curly hair, a cut that removes bulk in the right places often reduces how much product you need. See what the team does on the Highgate barber page.

Questions we get asked

Can I use hair oil every day?

On dry, coarse or coily hair, often yes, in small amounts. On normal hair, every few days or only after washing is usually plenty.

Should I put oil on my scalp?

Only if your scalp is genuinely dry and you know the oil suits you. If you have dandruff or an oily scalp, keep oil off it and speak to a pharmacist about the right shampoo.

Wet or dry hair?

Damp hair for most uses, since oil seals in water. A drop on dry ends between washes is fine too.

Will hair oil help my hair grow?

No reliable evidence says so. It can reduce breakage, which helps longer hair keep its length. For anything more, ask the Highgate Cuts team at your next cut or visit The Highgate House.
