How Often Should Men Wash Their Hair? It Depends on More Than You Think
Most men with straight or wavy hair do well washing with shampoo two to four times a week, rinsing with water on the days in between. Men with oily scalps, very short hair or who sweat heavily in the gym may need to shampoo most days. Men with curly, coily or Afro hair usually need far less, often once a week or every ten days, because natural oils travel down a curl slowly and the hair dries out easily. The right number is the one that keeps your scalp comfortable and your hair behaving, and it is worth adjusting by season.
Why there is no single answer
Shampoo has one main job: removing oil (sebum), sweat, dead skin and product from your scalp and hair. How quickly those build up varies a lot from man to man. Four things decide it:
- How much oil your scalp produces. Some scalps look greasy within a day, others are fine for four.
- Your hair texture. On straight hair, oil slides down the strand quickly and shows. On tight curls it barely moves, so the ends stay dry.
- Your hair length. Very short hair gets oily-looking fast because there is little length to absorb it, but it is also quick to wash and dry.
- What you do. Hard training, a cycle commute, a cap or helmet, or heavy styling product all change the picture.
A starting guide by hair type
| Hair type | Shampoo frequency to start with | Notes |
|---|---|---|
| Fine, straight, oily scalp | Daily or every other day | Use a gentle shampoo; one lather is usually enough |
| Normal straight or wavy | 2 to 4 times a week | Rinse with water between washes |
| Thick or coarse | 2 to 3 times a week | Conditioner helps manage dryness at the ends |
| Curly | 1 to 2 times a week | Conditioner-only washes in between can help |
| Coily or Afro | Every 7 to 10 days | Focus on moisture; see our Afro hair care routine |
| Very short or shaved | Daily is fine | Treat the scalp more like skin |
These are starting points. Try one for two or three weeks and adjust.
Signs you are washing too often
- Your scalp feels tight or itchy shortly after washing.
- Your hair looks dull, frizzy or straw-like at the ends.
- Small dry flakes appear, especially in winter.
- Curls lose their shape and look fluffy rather than defined.
If this is you, drop one wash a week and see whether things settle. Swapping to a milder shampoo can also help.
Signs you are not washing enough
- Your hair looks flat and greasy at the roots by the afternoon.
- Product builds up and your style stops holding.
- Your scalp is itchy with yellowish, greasy flakes.
- There is a noticeable smell from the scalp or a cap.
Greasy flakes and itching can be dandruff, which is common and usually manageable. The NHS guidance on dandruff recommends anti-dandruff shampoos and suggests seeing a GP if it does not improve after a month of treatment. Our post on dry scalp vs dandruff explains how to tell the two apart.
What about the gym?
Sweat on its own is mostly water and salt. If you train most days, you do not have to shampoo after every session. A thorough rinse with warm water and a fingertip scalp massage will clear most sweat. Shampoo every second or third session, or whenever your hair feels heavy. If you wear product, you may need shampoo more often, because sweat mixed with styling product clings to the scalp.
A cut that suits training also helps. We cover options in the best haircut for gym goers.
How to wash properly (it makes a difference)
- Wet your hair thoroughly with warm, not hot, water. Very hot water strips more oil and can irritate the scalp.
- Use a small amount of shampoo, roughly the size of a coin for short hair.
- Massage the scalp with your fingertips, not your nails, for 30 to 60 seconds. The scalp is what needs cleaning; the lengths get washed as the lather rinses through.
- Rinse fully. Leftover shampoo is a common cause of itch and flakes.
- Condition the lengths if your hair is longer than a few centimetres, curly or dry. Keep it off the scalp if your scalp is oily.
- Towel-dry by pressing, not rubbing. Rubbing roughs up the hair cuticle and causes frizz.
London water and the seasons
North London has hard water, which leaves mineral deposits on hair that can make it feel rough and look dull, and make shampoo lather less well. If your hair never feels quite clean, a clarifying shampoo once every couple of weeks can help. We cover it in more detail in hard water and your hair.
The seasons matter too. Central heating and cold air in winter dry the scalp, so many men find one fewer wash a week helps from November to March. In summer, more sweat and sun cream on the hairline may mean an extra wash.
What your barber can tell you
A barber sees and handles your scalp more closely than most people do. At Highgate Cuts, every visit starts with an assessment, where the barber looks at your hair and what you need and makes recommendations. If your scalp looks dry, oily or flaky, they can suggest how to adjust your routine, and point out if something looks worth showing a GP. The cut itself matters too: hair that is too heavy or long in the wrong places will look greasy sooner. A well-weighted cut from our barbers on Archway Road can make a day or two between washes look perfectly fresh.
Questions we get asked
Is it bad for men to wash their hair every day?
Not necessarily. With an oily scalp or very short hair, daily washing with a mild shampoo is fine. If your scalp feels tight or dry, cut back.
Does washing less make your hair less oily over time?
This is widely claimed, but the evidence is weak. Hair may feel more manageable once you find the right routine, but there is no reliable way to “train” your scalp.
Should I wash my hair before a haircut?
Clean, product-free hair helps the barber see how it naturally falls. See our post on washing hair before a haircut.
Is rinsing with water alone enough?
Between shampoo days, yes for most people. It clears sweat and loose debris but not oil or product.
