How often should you wash your hair? There is no single routine that works for everyone. The right wash schedule depends on your scalp type, hair texture, lifestyle, product use and overall hair condition.

Use this guide to understand your hair's needs, recognise when it is time to wash and find a routine that works for you.

How Often Should You Wash Your Hair?

Use these timings as a flexible starting point:

These are starting points, not strict rules. Fine and straight hair often shows oil sooner, while curly, coily, thick and coarse hair may need less frequent cleansing. Wash sooner if your scalp feels oily, itchy, uncomfortable or coated.

What Determines How Often You Should Wash Your Hair?

Exercise, weather, swimming and styling products can all affect how often your hair needs washing. Bleached, colour-treated or damaged hair may also benefit from gentler cleansing.

How Often Should You Wash Your Hair in Summer?

Heat, sweat and swimming may mean washing more frequently.

How Often Should You Wash Your Hair in Winter?

If your scalp and lengths feel drier, wash less frequently and focus on gentle, hydrating formulas.

For oily roots and dry ends, shampoo the scalp and condition the mid-lengths and ends.

How Often Should You Wash Your Hair for Scalp Health?

For good scalp health, wash often enough to remove excess oil, sweat, dead skin and product build-up without leaving your scalp feeling overly dry.

There is no ideal frequency for everyone. Oiliness, itching, flaking and build-up are better indicators than trying to reach a certain number of days between washes.

Explore scalp care products if your scalp needs extra support.

How Often Should You Wash Each Hair Type?

How often should you wash oily hair?

Oily hair may need washing every other day or daily if roots quickly become greasy or uncomfortable. A gentle shampoo is usually better than forcing long gaps between washes.

Try Hairburst Oily Scalp & Root Shampoo or Redken Amino-Mint Scalp Refresh Shampoo.

How often should you wash fine hair?

Fine hair may need washing every one to two days because oil can quickly leave the roots looking flat.

Redken Volume Injection Shampoo and Lightweight Conditioner adds lightweight body, while Alfaparf Milano Semi Di Lino Style & Care Texturising Dry Shampoo can refresh roots between washes.

How often should you wash dry hair?

Dry hair can often be washed once or twice a week. Choose hydrating formulas and concentrate conditioner or masks on the mid-lengths and ends.

Try Redken All Soft Moisturising Shampoo or Matrix Food For Soft Hydrating Shampoo, followed by Redken All Soft All-In Mask when extra moisture is needed.

How often should you wash wavy hair?

Wavy hair may suit washing two or three times a week. Wash sooner if styling products weigh down your hair or your waves lose their natural movement.

How often should you wash curly hair?

Curly hair can often be washed once or twice a week, depending on scalp oiliness and product build-up.

Umberto Giannini Curl Jelly Wash Shampoo gently cleanses wavy, curly and coily hair without leaving curls feeling stripped.

How often should you wash coily hair?

Coily hair may only need washing weekly or as needed because natural oils take longer to travel along tightly curled strands.

Try Umberto Giannini Coily Curls Moisture Shampoo for gentle cleansing and added moisture.

How often should you wash thick or coarse hair?

Thick or coarse hair may only need washing once or twice a week. Cleanse sooner if your scalp becomes oily, itchy or coated.

How Often Should You Wash Your Hair With Extensions?

Hair extensions generally need regular but gentle cleansing. Washing around two or three times a week can be a useful starting point, although you should always follow the aftercare advice for your specific extension type.

Focus shampoo on the scalp, avoid rubbing attachment points and apply conditioner mainly through the lengths. Dry the roots and attachment areas thoroughly, and avoid applying rich oils or conditioners directly to bonds or tapes unless advised otherwise.

How Often Should You Wash Blonde, Colour-Treated or Damaged Hair?

Blonde, colour-treated or damaged hair can often be washed one to three times a week, depending on your scalp. Frequent washing may contribute to colour fading, while damaged or bleached lengths may need extra conditioning.

Choose gentle, colour-safe formulas, use lukewarm water and focus shampoo on the scalp.

How often should you wash blonde hair?

Blonde hair does not need a particular wash schedule because of its colour alone. Base your routine on your scalp and hair condition.

Olaplex No.4P Blonde Enhancer Toning Shampoo can be used occasionally to neutralise unwanted yellow tones. Alternate with a gentle shampoo and follow the product directions.

What should you use on colour-treated or damaged hair?

Try Redken Acidic Bonding Concentrate Shampoo and Conditioner, Olaplex No.4 Bond Maintenance Shampoo or Pureology Hydrate Sheer.

For added shine, Redken Acidic Colour Gloss 1-Min Gloss-In-Mask can help leave colour-treated hair looking smoother and glossier.

How Often Should You Use a Hair Mask?

Once a week can be a useful starting point for dry, damaged, bleached or frequently heat-styled hair, while fine or healthy hair may need a mask less often.

Apply mainly through the mid-lengths and ends unless the product is designed for scalp use, and always follow the directions to avoid weighing hair down.

Explore hair masks for dry, damaged, coloured and textured hair.

How Can You Make Your Hair Last Longer Between Washes?

To keep hair fresher between wash days:

• Apply dry shampoo before roots become heavily greasy.

• Avoid repeatedly touching your hair.

• Keep brushes, pillowcases and styling tools clean.

• Use lightweight products around the roots.

• Apply oils and rich leave-ins mainly to the lengths.

• Avoid layering too many styling products.

Alfaparf Milano Semi Di Lino Style & Care Texturising Dry Shampoo helps absorb excess oil while adding body to flat roots.

Dry shampoo can refresh the appearance of your roots, but it does not remove sweat, dead skin or build-up in the same way as shampoo and water.

Should You Wash Your Hair After Every Workout?

Not necessarily. After light exercise, drying the roots or using a little dry shampoo may be enough. After heavy sweating, or if your scalp feels greasy or coated, shampooing is usually the better option.

How Do You Know When Your Hair Needs Washing?

It may be time to wash when:

• Roots look or feel greasy

• Your scalp feels itchy or uncomfortable

• Hair has lost volume

• Product build-up is visible

• Hair has developed an odour

• Flaking has increased

• Curls feel heavy or lose definition

• Dry shampoo no longer refreshes the roots

Oily roots and dry ends can happen at the same time, so cleanse the scalp while concentrating richer products on the lengths.

Do You Need a Clarifying Shampoo?

Clarifying shampoo removes excess oil, styling residue and mineral build-up. It can be useful if you regularly use dry shampoo, live in a hard-water area or notice your hair feels coated or heavy.

Use it occasionally rather than at every wash. Try Living Proof Clarifying Detox Shampoo, milk_shake Deep Detox Shampoo or Hairburst Exfoliating Scalp Scrub.

How to Wash Your Hair Properly

1. Wet your hair thoroughly with lukewarm water.

2. Apply shampoo mainly to the scalp.

3. Massage gently with your fingertips.

4. Let the lather rinse through the lengths.

5. Shampoo twice only when there is significant oil or build-up.

6. Apply conditioner from the mid-lengths to the ends.

7. Add a mask or treatment when needed.

8. Rinse thoroughly.

9. Blot with a towel rather than rubbing.

Focusing shampoo on the scalp helps remove oil and build-up without unnecessarily drying the lengths.

Can You Train Your Hair to Be Less Greasy?

Washing your hair less often does not reliably train the scalp to produce less oil. Extending wash days may make your routine more convenient, but it is unlikely to change your natural oil production.

If your scalp is genuinely oily, cleanse it rather than deliberately allowing heavy build-up.

FAQs

How many times a week should you wash your hair?

Two or three times a week works for many people, but there is no universal rule. Oily or fine hair may need more frequent washing, while dry, curly, coily or thick hair can often go longer.

Is it bad to wash your hair every day?

No. Daily washing can suit oily scalps, fine hair and active lifestyles. Use a gentle shampoo and condition the lengths if needed.

Can washing your hair less make it less oily?

Not reliably. Washing less may help you space out wash days, but it does not necessarily reduce how much oil your scalp produces.

Is washing your hair once a week enough?

It can be for dry, thick, curly or coily hair. Wash sooner if your scalp becomes oily, itchy or coated.

How often should you wash your hair if you have dandruff?

Follow the instructions on your anti-dandruff shampoo, as frequency varies by formula.

If you are looking for the best shampoo for dandruff, E45 Anti-Dandruff Dry Scalp Shampoo is designed for dry, itchy and flaky scalps. Seek professional advice if dandruff is persistent or severe.

Is dry shampoo bad for your scalp?

Not necessarily when used sparingly and washed out regularly. Repeated use without proper cleansing can allow residue to build up.

Should you shampoo twice?

Not at every wash. Double shampooing can help when there is significant oil, dry shampoo or styling-product build-up, but one thorough cleanse is usually enough.
