| QUICK ANSWER How often to wash hair depends on your scalp type, not a universal rule. Oily scalps often do well every two or three days, dry scalps less often, and balanced scalps somewhere between. Washing daily with something harsh can strip the scalp and make it oilier. How you wash matters as much as how often. |
“How often should I be washing it?”
I get asked that more than any other question, and my honest answer annoys people: it depends. Not on a rule from a magazine — on your scalp. So rather than give you a number, let me help you find yours.
Start With Your Scalp, Not a Rule
An oily scalp that’s greasy by the next morning needs cleansing more often than a dry one that feels tight after washing. As a rough guide to how often to wash hair: oily scalps often settle at every two or three days, dry scalps less often, balanced ones somewhere in between.

How Often to Wash Hair Changes After 40
This catches a lot of women out. The rhythm that worked for twenty years suddenly doesn’t. Hormonal changes around menopause can make the scalp oilier, drier, or both at once — oily at the root, dry at the ends.
So if your old routine has stopped working, it’s not you doing something wrong. Your scalp has changed, and the routine needs to change with it.
Why Washing More Often Can Backfire
Washing too often, or with something too harsh, strips the scalp of its natural oil. Many scalps answer by producing more. You wash because it’s greasy; it gets greasier because you washed.
If you’re washing every day and you’re still greasy by evening, the washing may be part of the problem. I go into that loop in greasy scalp after washing .
How You Wash Matters Just as Much
Shampoo the scalp. That’s where the oil and build-up are. The lengths get cleaned as the lather rinses through — they don’t need scrubbing.
Use your fingertips, not your nails. Small circles. It cleans better, and it’s kinder.
Condition the ends only. Conditioner on the roots weighs fine hair down and makes it greasy faster.
Rinse longer than you think. Leftover shampoo and conditioner are a common, hidden cause of limp, greasy-looking roots. In a hard-water area, minerals add to that residue — more on that in hard water and hair .
Choose a gentle cleanser. Strong cleansers suit some scalps and irritate others. I explain the difference in sulfate-free shampoo .
Changing Your Rhythm
If you’re changing how often to wash hair, give your scalp two to three weeks to adjust. The first week can feel worse. Most people who stick with it find things settle.
Judging a new routine after three days is the commonest mistake I see.
What About Dry Shampoo?
Useful for stretching a day. A problem if it’s replacing washing. It leaves residue on the scalp that builds up over time — the opposite of what the skin needs. Occasional, not structural.
A Dry, Tight Scalp
If your scalp feels tight every time you wash, wash a little less often and with something gentler, and add some light hydration afterwards. Aloe vera for the scalp is lovely for that.
If flaking, itching or soreness doesn’t settle, see your GP or pharmacist. The NHS page on dandruff explains when a medicated shampoo helps, and the British Association of Dermatologists has more on scalp conditions.
On the Days In Between
Washing less often doesn’t mean ignoring your scalp. A light leave-in and a minute of massage between washes keeps it comfortable. That’s what I made Nunu Moor for — a botanical scalp and hair tonic that doesn’t need rinsing out and won’t leave you greasy. Join the Nunu Moor waitlist to hear first.
So, how often to wash hair? As often as your scalp needs, and no more — washed well, gently, with the right things in the right places. Your scalp will tell you. It just needs a few weeks to be heard.
