How to Properly Use Purple Shampoo After Your Initial Wash
The Right Way to Remove Brassiness Without Over-Toning or Drying Out Your Blonde Hair
You invested the time, money, and patience to achieve beautiful blonde hair.
Then a few weeks later, something happens.
The bright, cool blonde you left the salon with starts looking:
-
Yellow
-
Golden
-
Warm
-
Dull
-
Brassy
That's usually when someone tells you:
“You need purple shampoo.”
They're probably right.
But there's another question that doesn't get answered nearly enough:
Should you wash your hair with regular shampoo before using purple shampoo?
For many people, the answer is yes.
Using your normal shampoo first can remove excess oil, sweat, dry shampoo, and styling-product buildup so your purple shampoo can focus on what it is actually meant to do:
deposit violet pigment that helps visually neutralize unwanted yellow tones.
At Crave Theory Cosmetics, we believe every product in a routine should have a specific job.
Your regular shampoo cleans.
Your purple shampoo tones.
Your conditioner restores softness.
Your leave-in supports the lengths.
Understanding that order can make the difference between beautifully toned blonde hair and hair that becomes dull, unevenly purple, or unnecessarily dry.
What Is Purple Shampoo?
Purple shampoo is a pigmented shampoo formulated with violet or purple colorants.
Its purpose is primarily to help neutralize unwanted yellow tones in blonde, platinum, silver, gray, or highlighted hair.
Why purple?
Because of basic color theory.
On the color wheel:
Purple sits opposite yellow.
When violet pigments are deposited onto yellow-looking blonde hair, they can make that warmth appear more neutral and cooler.
This is why purple shampoo is especially popular for:
-
Platinum blonde hair
-
Icy blonde hair
-
Highlighted blonde hair
-
Balayage
-
Bleached hair
-
Gray hair
-
Silver hair
-
White hair
-
Naturally light blonde hair
But there is an important limitation.
Purple Shampoo Doesn't Lighten Hair
Purple shampoo is not bleach.
It cannot turn brown hair blonde.
It cannot lift dark roots.
It cannot take orange hair all the way to icy platinum.
It mainly provides temporary tone correction by depositing violet pigment.
If your blonde is too dark or strongly orange, the issue may require additional professional color correction rather than simply more purple shampoo.
Why Does Blonde Hair Become Brassy?
Even beautifully toned blonde rarely stays exactly the same shade forever.
Brassiness can develop because of:
-
Toner fading
-
Frequent shampooing
-
UV exposure
-
Heat styling
-
Hard-water minerals
-
Chlorine
-
Product buildup
-
Environmental exposure
-
Naturally warm underlying pigment
When blonde hair is chemically lightened, underlying warm tones are exposed.
A salon toner helps refine those tones initially, but toner gradually fades.
Purple shampoo can help maintain the cooler appearance between salon appointments.
Should Purple Shampoo Be Your First Shampoo?
It can be.
But it doesn't always have to be.
If your hair is relatively clean and you're simply refreshing your blonde tone, you may use your purple shampoo directly according to the manufacturer's instructions.
However, if your scalp and hair have:
-
Excess oil
-
Dry shampoo
-
Sweat
-
Hair spray
-
Styling cream
-
Leave-in buildup
-
Several days of accumulated products
using your regular shampoo first may provide a cleaner foundation for more even toning.
This is the routine we prefer for a more intentional purple-shampoo wash day:
CLEANSE → TONE → CONDITION → LEAVE-IN CARE
STEP 1: Begin With Crave Theory Hydrating Repair Shampoo
Before trying to correct your blonde tone, start by properly cleaning your hair.
Use Crave Theory Hydrating Repair Shampoo.
Shop Crave Theory Hydrating Repair Shampoo
Crave Theory's Hydrating Repair Shampoo is designed for dry, damaged, color-treated, and overprocessed hair and uses a creamy, soft-lather cleansing system formulated without SLS or SLES sulfates.
That makes it a natural first step for blonde hair, which may already have experienced significant chemical processing.
The formula features CloudBond™ Blend, including:
Amino Acids
Support softer and stronger-feeling hair.
Ceramide NP
Helps improve the smooth appearance and feel of stressed strands.
Panthenol
Helps retain moisture and support softness.
Plant Protein
Supports damaged-feeling hair as part of the CloudBond™ system.
Why Cleanse Before Purple Shampoo?
Think of your first shampoo as clearing the canvas.
Your regular shampoo helps remove:
oil + sweat + dirt + dry shampoo + styling residue
Then your purple shampoo can concentrate more effectively on:
toning unwanted yellow.
This is especially helpful if you only wash your hair a few times per week or regularly use styling products.
How to Perform Your Initial Wash
Wet your hair thoroughly with lukewarm water.
Apply a small amount of Crave Theory Hydrating Repair Shampoo primarily to your scalp.
Massage gently using your fingertips for approximately 60–90 seconds, following the product directions, and then rinse thoroughly.
The American Academy of Dermatology recommends concentrating shampoo primarily on the scalp, where product buildup, oil, and dead skin accumulate, rather than aggressively scrubbing shampoo through the entire hair length.

STEP 2: Rinse Your First Shampoo Completely
Do not simply layer purple shampoo on top of your first shampoo.
Rinse the Crave Theory shampoo out thoroughly.
Make sure water reaches:
-
The roots
-
Crown
-
Hairline
-
Nape
-
Behind the ears
-
Mid-lengths
-
Ends
Now your hair is ready for the toning step.
STEP 3: Apply Your Purple Shampoo
After rinsing your initial shampoo, apply your chosen purple shampoo according to that manufacturer's directions.
This matters because purple shampoos vary considerably in pigment strength.
Some are pale violet.
Others are so heavily pigmented they almost look like ink.
The stronger the pigment, the more cautious you need to be about application time.
Where Should You Apply Purple Shampoo?
Focus particularly on areas where you see unwanted yellow.
That may include:
-
Face-framing highlights
-
Mid-lengths
-
Ends
-
Top layers
-
Previously bleached areas
Distribute the product as evenly as possible.
Uneven application can create uneven toning.
STEP 4: Don't Assume Longer Means Better
One of the biggest purple-shampoo mistakes is thinking:
“If five minutes is good, 30 minutes must be amazing.”
Not necessarily.
Purple shampoo deposits pigment.
Leaving a strong formula on too long can result in:
-
Lavender sections
-
Purple ends
-
Grayish areas
-
Dull-looking blonde
-
Uneven tone
Porous areas of blonde hair can sometimes absorb pigment more aggressively than healthier sections.
Always follow the timing instructions on the purple-shampoo bottle.
If you're using a new product for the first time, start conservatively.
Your Goal Is Icy Blonde.
Not Accidental Lavender.
How Long Should Purple Shampoo Stay On?
There is no universal time.
Some formulas are designed for quick use.
Others are meant to remain on the hair for several minutes.
Follow the instructions on your particular product.
Factors that can affect how quickly your hair grabs violet pigment include:
-
Porosity
-
Degree of bleaching
-
Hair condition
-
Starting blonde shade
-
Product concentration
-
Previous toning treatments
Very porous platinum ends may grab purple significantly faster than darker blonde roots.
STEP 5: Rinse the Purple Shampoo Thoroughly
Once the recommended processing time has passed, rinse thoroughly with lukewarm or cool water.
Continue rinsing until the excess product is gone.
Now evaluate your hair.
It may already look cooler while wet, although the true result will be easier to judge once dried.
STEP 6: Always Follow With Conditioner
This step matters tremendously for blonde hair.
Chemically lightened hair often needs additional conditioning because bleaching can leave the hair drier and more fragile.
The American Academy of Dermatology notes that lightening can make hair more vulnerable to dryness and brittleness, particularly when hair is lifted significantly lighter than its natural shade.
After your purple shampoo, follow with Crave Theory Softening Repair Conditioner.
Shop Crave Theory Softening Repair Conditioner
Crave Theory positions this conditioning step around:
-
Slip
-
Softness
-
Easier detangling
-
Moisture
-
Manageability
The brand describes the Softening Repair Conditioner as providing “slip you feel before the rinse” and softness afterward.
Apply primarily through the mid-lengths and ends.
If your hair is extremely dry or heavily bleached, distribute according to where your hair needs conditioning most.
STEP 7: Treat Wet Blonde Hair Gently
Bleached hair deserves patience.
Do not aggressively rub your wet hair with a towel.
Do not immediately drag a brush through knots.
Gently squeeze or blot away excess water.
Use a wide-tooth comb when appropriate and detangle carefully.
The American Academy of Dermatology advises gentle handling of wet hair because hair is particularly delicate when wet.
STEP 8: Follow With Crave Theory Leave-In Repair Veil
After cleansing, toning, and conditioning, the next priority is keeping your blonde lengths soft and manageable.
Apply Crave Theory Leave-In Repair Veil according to your hair's needs.
Shop Crave Theory Leave-In Repair Veil
Crave Theory positions the Leave-In Repair Veil as the step that provides wash-day softness on days you didn't wash, making it particularly relevant to processed blonde hair that benefits from continued conditioning support between wash days.
Focus mainly on:
Mid-lengths → Ends
rather than automatically applying large amounts to your roots.
The American Academy of Dermatology notes that leave-in conditioners can be particularly useful for color-treated, dry, heat-styled, long, frizzy, or tangled hair.

STEP 9: Don't Forget Your Scalp
Your blonde lengths receive a lot of attention.
Your scalp deserves some too.
Crave Theory Peptide Dew Drops can be incorporated separately as the scalp-care step within your broader routine.
Shop Crave Theory Peptide Dew Drops
Crave Theory's philosophy separates scalp care from length care instead of expecting one product to do everything. The brand positions Peptide Dew Drops as the dedicated scalp step within its four-product routine.
If your scalp has recently been bleached and is still:
-
Burning
-
Red
-
Tender
-
Irritated
-
Broken
wait until it feels normal before experimenting with additional scalp products.
Significant irritation after chemical processing should be treated seriously.
The Ideal Purple Shampoo Routine
Here's the complete sequence:
1. CLEANSE
Crave Theory Hydrating Repair Shampoo
Remove oil, sweat, and styling buildup.
2. RINSE
Thoroughly remove your initial shampoo.
3. TONE
Purple Shampoo
Apply primarily where unwanted yellow is visible.
Leave on only as directed.
4. RINSE AGAIN
Remove all violet shampoo.
5. CONDITION
Crave Theory Softening Repair Conditioner
Restore softness and slip.
6. LEAVE-IN CARE
Crave Theory Leave-In Repair Veil
Support soft, manageable blonde lengths after washing.
7. SCALP CARE
Crave Theory Peptide Dew Drops
Use separately as part of your scalp-care routine when appropriate.
Should You Use Purple Shampoo Every Time You Wash?
Usually, no.
Purple shampoo should solve a color problem.
If your blonde isn't yellow, you don't necessarily need more violet pigment.
Overusing a strongly pigmented purple shampoo can potentially make your blonde appear:
-
Dull
-
Grayish
-
Flat
-
Lavender
-
Unevenly toned
Instead, look at your hair.
When unwanted yellow begins to return, use your toning shampoo.
On other wash days, return to your regular Crave Theory Hydrating Repair Shampoo.
How Often Should You Use Purple Shampoo?
For many blondes, a reasonable starting point might be once every few washes, then adjusting according to the product's strength and how quickly your hair becomes brassy.
Some people may need it approximately once a week.
Others may need it less frequently.
Your schedule depends on:
-
Your blonde shade
-
How quickly your toner fades
-
Your water quality
-
Hair porosity
-
Frequency of washing
-
Sun exposure
-
Styling habits
-
Strength of your purple shampoo
Watch your color rather than blindly following the calendar.
Purple Shampoo Is for Yellow—Not Every Kind of Brass
This is one of the most important lessons in blonde maintenance.
Yellow Hair
Purple can help.
Orange Hair
Purple generally isn't the ideal correction.
Why?
Color theory again.
Purple neutralizes yellow.
Blue neutralizes orange.
If your hair remains strongly orange after bleaching, the problem may be that it hasn't been lifted light enough for the icy-blonde result you're trying to achieve.
Adding more purple shampoo won't necessarily solve that.
Who Should Use Purple Shampoo?
Purple shampoo is most useful for:
Icy Blonde Hair
Helps preserve cooler tones between professional toning appointments.
Platinum Blonde Hair
Helps counteract unwanted pale-yellow warmth.
Highlighted Hair
Can help cooler blonde highlights maintain their tone.
Balayage
Useful when lightened sections begin shifting yellow.
Gray or Silver Hair
Violet pigment can sometimes help reduce yellowish warmth in naturally gray or silver hair.
Bleached Blonde Hair
Useful once hair has been lifted sufficiently and unwanted yellow emerges.
Who Probably Doesn't Need Purple Shampoo?
If your hair is:
-
Dark brown
-
Black
-
Warm brunette without blonde highlights
-
Copper
-
Red
-
Intentionally golden blonde
purple shampoo may not be relevant to your desired color.
If you love your warm honey blonde:
Don't neutralize the warmth you paid your colorist to create.
Should You Double Shampoo Before Purple Shampoo?
Usually not.
Remember:
Purple shampoo becomes your second cleansing step.
If you do:
Regular shampoo → regular shampoo → purple shampoo
you've effectively shampooed three times.
For many people, that is unnecessary.
One thorough cleanse with Crave Theory Hydrating Repair Shampoo, followed by your toning shampoo, should generally provide enough cleansing for a purple-shampoo wash day.
If your hair has unusually heavy buildup, adjust according to your needs.
Should You Apply Purple Shampoo to Dry Hair?
You may see this technique on social media.
Applying heavily pigmented purple shampoo to dry hair can dramatically increase pigment pickup in certain areas because dry, porous hair may absorb the product unevenly.
That also increases the possibility of:
-
Patchiness
-
Purple sections
-
Uneven toning
Unless the manufacturer specifically recommends dry application, wet-hair application is generally the more predictable choice.
What If Your Ends Turn Purple?
Don't panic.
Over-toning from purple shampoo is generally temporary.
Stop using purple shampoo for your next several washes and return to your regular cleanser.
Use:
Crave Theory Hydrating Repair Shampoo → Softening Repair Conditioner → Leave-In Repair Veil
and allow the excess violet pigment to fade gradually.
Avoid immediately trying to “fix” the situation with more chemical processing.
What If Purple Shampoo Makes Your Hair Feel Dry?
Not all purple shampoos are formulated the same way.
Some highly pigmented toning cleansers may leave processed hair feeling drier.
That's another reason we prefer separating the jobs:
Let purple shampoo tone.
Let your conditioning routine condition.
Immediately follow your toning step with conditioner.
Then provide appropriate leave-in support.
What About Purple Conditioner?
Purple conditioners and masks can offer another way of depositing violet pigment while providing conditioning.
You don't necessarily need:
Purple shampoo + purple conditioner + purple mask
all in the same wash.
That may produce more pigment than your hair requires.
Start simple.
Adjust based on what your hair actually looks like afterward.
How to Keep Blonde Hair Cool Between Purple Shampoo Washes
Purple shampoo is only part of blonde maintenance.
You should also consider:
Reduce Unnecessary Heat
Repeated high-temperature styling can increase stress on already-lightened hair.
Protect Blonde Hair From Excessive Sun
The American Academy of Dermatology notes that sun exposure can contribute to fading, dryness, roughness, and brittleness in dyed or bleached hair.
Read AAD Hair Coloring and Care Guidance
Watch Hard-Water Buildup
Mineral accumulation may change how blonde hair looks and feels.
Be Careful Around Chlorine
Rinse blonde hair thoroughly after swimming.
Don't Overwash
Wash according to your scalp needs rather than automatically shampooing every day.
Condition Consistently
Blonde hair can look much more beautiful when it has shine and movement.
A perfectly toned blonde that feels brittle isn't the goal.

Frequently Asked Questions About Purple Shampoo
Do I use regular shampoo before purple shampoo?
You can, particularly when you have oil, sweat, dry shampoo, or styling-product buildup. A regular first cleanse removes buildup so the purple shampoo can focus on depositing violet pigment.
Can Crave Theory Hydrating Repair Shampoo be used before purple shampoo?
Yes. Crave Theory positions Hydrating Repair Shampoo for dry, damaged, color-treated, and overprocessed hair, and it is formulated without SLS/SLES sulfates.
Should I use conditioner after purple shampoo?
Yes, particularly if your blonde is dry or chemically lightened. Conditioner helps moisturize and detangle hair after cleansing.
Does purple shampoo bleach your hair?
No. Purple shampoo deposits violet pigment to visually neutralize yellow. It does not significantly lighten the natural or artificial pigment in your hair.
Does purple shampoo work on orange hair?
Purple is primarily useful for yellow tones. Orange generally requires blue-based correction or further professional color correction depending on the starting level.
Can I leave purple shampoo on for 30 minutes?
Only if the manufacturer specifically says to do so. Strongly pigmented shampoos can over-tone porous blonde hair.
Why did my blonde hair turn purple?
Your hair may be very porous, the shampoo may be strongly pigmented, or you may have left the product on too long.
How do I remove excess purple shampoo?
Temporarily stop using the toning product and return to your normal shampoo routine. Excess deposited violet pigment generally fades with washing.
Can I use purple shampoo every day?
Most people don't need to. Use it according to the product instructions and when your blonde actually begins showing unwanted yellow.
Does purple shampoo replace toner?
Purple shampoo helps maintain a cool tone. It does not necessarily replace a professionally formulated salon toner, particularly when significant color correction is required.
The Biggest Purple Shampoo Mistake
The biggest mistake isn't necessarily leaving purple shampoo on for one minute too long.
It's expecting purple shampoo to do every job.
Purple shampoo isn't your:
-
Bleach
-
Professional toner
-
Repair treatment
-
Conditioner
-
Scalp serum
-
Complete wash-day routine
Its primary job is straightforward:
Help neutralize unwanted yellow.
Let it do that job.
Then let the rest of your routine do theirs.
At Crave Theory Cosmetics, that's how we think great hair care should work.
Clean first. Tone second. Condition afterward. Care consistently.
Because keeping your blonde icy isn't about pouring more purple onto it.
It's about knowing exactly when—and how—to use it.
