How Often Should You Wash Your Hair?

How Often Should You Wash Your Hair? A Hairdresser’s Guide

How often should you wash your hair?

Every day? Twice a week? Once a week?

If you spend any time on social media, you’ve probably heard everything from “never wash your hair every day” to “you need to train your hair to produce less oil.”

The reality is much simpler:

There is no perfect hair-washing schedule that works for everyone.

How often you should shampoo depends on your scalp, hair type, texture, lifestyle, colour, styling habits and the products you use.

Someone with fine hair and an oily scalp may feel best washing every day or two, while someone with thick, dry or curly hair may comfortably go much longer.

At Chroma Hair & Co in Highgate Hill, Brisbane, we’d rather help clients find a routine that works for their hair than follow arbitrary rules from social media.

So, how often should you actually wash your hair?

Here’s what you need to know.

Why Do We Wash Our Hair?

Your scalp naturally produces sebum, an oily substance that helps lubricate the scalp and hair.

Throughout the day, your scalp and hair can also accumulate:

• Sweat

• Oil

• Dead skin cells

• Styling products

• Dry shampoo

• Environmental dirt and pollutants

Shampoo helps remove this build-up.

The goal isn't to make your scalp completely oil-free.

It's to cleanse it appropriately while keeping your hair and scalp comfortable and manageable.

And that's why washing frequency varies so much from person to person.

So, How Often Should You Wash Your Hair?

There isn't one correct answer, but as a general starting point:

Hair / Scalp TypePossible Starting PointFine + oily hairEvery 1–2 daysNormal hair/scalpEvery 2–4 daysThick hairEvery 3–5 daysDry hairEvery 3–7 daysCurly/coily hairOften every 4–7+ daysBlonde/lightened hairUsually based on scalp needs while protecting the lengthsVery active/sweaty lifestylePotentially more frequently

These are guidelines rather than rules.

If your scalp feels oily, uncomfortable or heavily coated before your scheduled "wash day", you don't need to suffer simply because somebody online told you that washing twice a week is ideal.

1. Fine Hair May Need Washing More Frequently

Fine hair often shows oil faster than thicker hair.

That's partly because even a relatively small amount of oil can travel through and visibly weigh down fine strands.

You might notice:

• Flat roots

• Loss of volume

• Hair separating into oily sections

• Difficulty maintaining your style

If that's you, washing every day or every second day may work perfectly well when you're using an appropriate shampoo.

Trying to force fine, oily hair to last an entire week between washes may simply leave you uncomfortable and reaching for excessive amounts of dry shampoo.

2. Oily Scalps May Need More Frequent Cleansing

If your scalp naturally produces more oil, you may simply need to shampoo more frequently.

Oil production differs between people.

Your lifestyle can also affect how quickly your scalp feels dirty.

For example:

• Exercise

• Sweating

• Wearing hats

• Hot weather

• Styling products

can all affect how frequently you want to wash.

And living in Brisbane's warm, humid climate can certainly influence how fresh your scalp feels, particularly during summer.

3. Dry Hair May Benefit From Less Frequent Washing

If your hair is naturally dry, coarse or porous, frequent cleansing—particularly with an unsuitable shampoo—may leave the lengths feeling even drier.

You may be able to comfortably go several days between washes.

The important distinction is between your scalp and your hair.

You can have:

an oily scalp + dry ends.

This is extremely common, particularly with long or colour-treated hair.

In that situation, you still need to cleanse the scalp appropriately while protecting and conditioning the lengths.

4. How Often Should You Wash Blonde Hair?

Being blonde doesn't automatically determine how frequently you should wash your hair.

Your scalp should still guide your cleansing frequency.

However, lightened blonde hair can be more porous and may require additional attention through the lengths.

Frequent washing can also mean your toner gradually fades sooner.

For blonde clients, we generally focus on:

• Using appropriate colour-safe shampoo

• Conditioning the mid-lengths and ends

• Using treatments when required

• Limiting unnecessary excessive heat

• Using toning products appropriately

• Protecting the hair's condition

At Chroma Hair & Co, we use and recommend professional haircare from NAK Hair and MilkShake, with products selected according to the client's particular blonde and hair condition.

5. What About Coloured Hair?

If you've invested in professional hair colour, naturally you want it to stay looking beautiful for as long as possible.

Repeated washing can contribute to gradual colour fade, particularly with certain tones.

Bright colours, coppers, reds and some toners can be particularly sensitive to fading.

But that doesn't mean you should avoid washing an oily or uncomfortable scalp simply to preserve your colour.

Instead, focus on:

• Appropriate colour-care products

• Avoiding unnecessarily harsh cleansing

• Using sensible water temperatures

• Conditioning properly

• Following the maintenance routine recommended by your colourist

Good colour maintenance is about how you wash your hair as well as how often.

6. How Often Should You Wash Curly Hair?

Curly and coily hair often behaves very differently from straight hair.

Natural oils can take longer to travel along the bends and curves of the hair shaft, meaning the lengths may remain relatively dry even when the scalp produces normal amounts of oil.

For that reason, many people with curly hair prefer less frequent shampooing.

However, curl pattern isn't the only consideration.

Someone with fine curls and an oily scalp may still prefer washing more frequently than someone with very thick, coarse curls.

Again:

Your individual scalp and hair matter more than a universal schedule.

7. What If You Exercise Every Day?

This is a very common question.

If you exercise frequently and sweat heavily, you may naturally want to wash more often.

You don't necessarily have to shampoo after every single workout, particularly if your scalp still feels comfortable.

Some people can:

• Rinse when appropriate

• Restyle their hair

• Use dry shampoo strategically

• Tie their hair back during exercise

and comfortably wait until their usual wash day.

Others find their scalp feels oily, sweaty or uncomfortable and prefer to shampoo.

Neither approach is automatically wrong.

Is Washing Your Hair Every Day Bad?

Not necessarily.

This is one of the biggest haircare myths.

Daily washing isn't automatically bad for your hair.

For someone with a very oily scalp, fine hair or an active lifestyle, frequent cleansing may be completely appropriate.

The bigger questions are:

What are you washing it with?

and

What condition are your lengths in?

If you're washing dry, heavily lightened hair every day with an overly strong shampoo, then aggressively blow-drying and straightening it afterwards, your overall routine may contribute to dryness.

But that doesn't mean everyone needs to avoid daily washing.

Can You "Train" Your Hair to Become Less Oily?

You've probably heard this one:

"Stop washing your hair and eventually your scalp will learn to produce less oil."

It's an appealing idea, but it's an oversimplification.

How oily your scalp becomes is influenced by factors including your individual biology and hormones.

Stretching your washes may help you become more comfortable with some natural oil or reduce how frequently you're styling your hair, but you shouldn't feel as though you've failed because your scalp still becomes oily after a day or two.

If your scalp needs washing, wash it.

You don't earn extra points for reaching day seven.

How Should You Actually Shampoo Your Hair?

Technique matters more than many people realise.

Focus on your scalp

Shampoo is primarily there to cleanse your scalp and roots.

You generally don't need to aggressively scrub shampoo into your ends.

When you rinse, the cleanser naturally passes through the lengths.

Use your fingertips

Massage the scalp gently with your fingertips rather than scratching aggressively with your nails.

Rinse thoroughly

Product left behind can contribute to hair feeling heavy or coated.

Follow with conditioner

Apply conditioner primarily through the mid-lengths and ends, particularly if your hair is longer, coloured or dry.

Should You Shampoo Twice?

Sometimes, yes.

You may have noticed your hairdresser shampooing your hair twice at the basin.

There's a reason.

If your scalp has significant:

• Oil

• Dry shampoo

• Styling products

• Sweat

• Product build-up

the first shampoo may primarily begin removing that accumulation.

A second shampoo can then cleanse more effectively.

But you don't necessarily need to double-shampoo every single time.

It depends on your hair, products and how long you've gone between washes.

What About Dry Shampoo?

Dry shampoo can be incredibly useful.

It can absorb excess oil and help extend your style between washes.

But it isn't actually washing your hair.

Think of dry shampoo as a styling and oil-absorbing product, not a replacement for shampoo and water indefinitely.

Repeatedly layering dry shampoo onto an increasingly oily scalp can lead to significant product build-up.

Use it strategically.

And when it's time to properly cleanse your scalp—wash your hair.

Does Hot Water Damage Hair?

Very hot water can be unnecessarily harsh on both the scalp and hair.

You don't need to endure freezing cold showers for beautiful hair, but using warm rather than excessively hot water is generally a sensible approach.

This can be particularly relevant for colour-treated or dry hair.

Why Does My Hair Feel Greasy Straight After Washing?

If your hair feels oily, heavy or coated shortly after washing, several things could be happening.

You may be:

• Using products that are too heavy for your hair

• Applying conditioner too close to the scalp

• Not rinsing thoroughly

• Using excessive styling products

• Experiencing product build-up

• Not cleansing effectively enough

Fine hair in particular can become weighed down by rich products that may work beautifully on thicker or drier hair.

This is why copying somebody else's hair routine doesn't always work.

What Products Should You Use?

There's no single "best shampoo" for everyone.

At Chroma Hair & Co, we work with NAK Hair and MilkShake professional haircare and recommend products according to the individual client.

Someone with:

Fine, oily hair

may need something completely different from someone with:

Thick, dry, lightened blonde hair.

Likewise, a client trying to preserve a beautiful salon colour may have different needs from someone with untreated hair.

Your shampoo should suit your scalp, while your conditioner and treatments should also address the needs of your lengths and ends.

How Do You Know You're Washing Too Often?

Your routine may need adjusting if your hair consistently feels:

• Very dry after washing

• Rough

• Difficult to detangle

• Frizzy

• Brittle through the ends

However, washing frequency may not be the only cause.

Heat styling, lightening, environmental exposure, unsuitable products and overdue haircuts can all contribute to dry-feeling hair.

That's why it's worth looking at your entire routine rather than blaming shampoo alone.

How Do You Know You're Not Washing Often Enough?

Your scalp may be telling you it's time to wash if you're experiencing:

• Significant oiliness

• Heavy product build-up

• Hair that feels coated

• Persistent scalp discomfort

• Excessive dry shampoo accumulation

• Hair that's difficult to style because of oil and build-up

Your scalp doesn't care what day TikTok says your next wash should be.

Listen to your hair and scalp.

A Simple Hair-Washing Routine

For most people, it doesn't need to be complicated.

Step 1: Thoroughly wet your hair.

Step 2: Apply an appropriate amount of shampoo primarily to the scalp.

Step 3: Massage gently with your fingertips.

Step 4: Rinse thoroughly.

Step 5: Shampoo again if genuinely required.

Step 6: Apply conditioner to the mid-lengths and ends.

Step 7: Leave it for the recommended time.

Step 8: Rinse thoroughly.

Step 9: Apply appropriate leave-in products and heat protection before styling.

That's it.

You don't necessarily need a twelve-product routine to have beautiful hair.

Frequently Asked Questions

How many times a week should you wash your hair?

There isn't a universal number. Some people may need to wash daily or every second day, while others may comfortably wash once or twice a week. Your scalp, hair type, lifestyle and condition should determine your routine.

Is it okay to wash your hair every day?

For some people, yes. Daily washing isn't inherently wrong. Using appropriate products and considering the condition of your hair is more important than following an arbitrary rule.

Is washing your hair once a week enough?

For some hair and scalp types, it can be. For others—particularly fine or oily hair—it may not be frequent enough.

How often should you wash oily hair?

Oily hair may require daily or every-second-day cleansing, although individual needs vary.

How often should you wash blonde hair?

Wash according to the needs of your scalp while using appropriate products to protect the condition and tone of your lightened lengths.

Does washing hair make it more oily?

Washing doesn't simply "teach" everyone's scalp to produce more oil. Oil production varies between individuals, and there's no need to deliberately tolerate an uncomfortable oily scalp in an attempt to train it.

Should I shampoo twice?

Double shampooing can be useful when there's substantial oil, dry shampoo or product build-up. It isn't automatically necessary at every wash.

Can dry shampoo replace washing?

No. Dry shampoo can absorb oil and extend a hairstyle, but it doesn't replace cleansing your scalp with shampoo and water.

So, How Often Should You Really Wash Your Hair?

Forget the idea that everyone needs to wash their hair on exactly the same schedule.

The best routine is the one that keeps your scalp comfortable and your hair looking and feeling healthy.

For you, that might mean every day.

It might mean every three days.

It might mean once or twice a week.

What's more important is choosing products suited to your hair, cleansing properly and looking after your lengths between washes.

At Chroma Hair & Co in Highgate Hill, Brisbane, our stylists can assess your hair, scalp, colour and current routine and recommend professional home care suited specifically to you.

We work with NAK Hair and MilkShake professional haircare and can help take the guesswork out of choosing the right products.

Because when it comes to washing your hair, there isn't one perfect schedule.
