Best shampoo for colored hair: 60 washes is not 60 days

Two locks of the same red-brown hair side by side on natural linen, one freshly colored and one faded and dulled, in soft daylight

We read the eight official pages and put them in one table. Two of these bottles print the number 60 and do not mean anything like the same thing. And two of the most expensive promise nothing about how long your color lasts.

The one explaining its own figure best
L'Oréal Paris Elvive Color Vibrancy Protecting Shampoo
It is the only one of the eight putting its full condition next to the number: how many washes a week, and that the figure is for the shampoo with its conditioner. That makes it checkable. Note it is one of the three carrying sulfates, and it publishes that on its own list.
If you avoid sulfates and want to know what that means
Living Proof Restore Shampoo
It is the only one saying what it means by "sulfate free", naming the two it leaves out. The rest leave it on the label without defining it. Note: it promises nothing about color lasting, its figures are about breakage.
If your hair comes from bleaching
Olaplex No.4 Bond Maintenance Shampoo
Its figures are about repair and breakage, not color: on color it only says it is safe. That is honest and it is exactly what you want if your problem is breakage. It also publishes how many washes each bottle gives, which no other does.
Read its label before its number
Pantene Pro-V Radiant Color Shine Shampoo
Its own brand publishes an article recommending you choose sulfate free products, and this one carries two, per the ingredient list it publishes on its Canadian page. Its US page publishes no list. It is the least expensive of the list.

This is us: we make Blendsor, the colour formula app for salons. We spend our days reading hair colour technical sheets, so reading labels is the job.

Before you buy

Two of these eight bottles print the number 60 on the shelf. One says up to 60 washes, with no condition beside it. The other says up to 60 days, and clarifies in its small print that this means four washes a week using its shampoo with its conditioner: around 34 washes, almost half. Anyone comparing the two labels thinks they are comparing the same thing. And there is something repeated across the category: of the four that give a figure, the three which explain how they measured it measured with the conditioner on. You buy one bottle and the number comes from two. That explains "it did not last what it said" better than anything else.

The seal says what each brand publishes about color duration. It does not measure whether the product works: a bottle with no figure can be excellent at its own job.

Two bottles with the same number that do not mean the same

Here is what came out of putting the eight labels in one table.

Two of these shampoos print the number 60, and there is almost double the distance between them.

One promises up to 60 washes, with no condition beside it. No asterisk, no test cited, nothing.
The other promises up to 60 days, and its small print explains exactly what that means: four washes a week, using its shampoo with its conditioner.

Do the maths and those 60 days are around 34 washes. Anyone comparing the two labels on the shelf thinks they are comparing the same thing, and they are comparing one figure with almost double another.

The interesting part is not which one wins, it is which one can be checked. One of the two gives you everything you need to verify it. The other gives you a round number and nothing else.

None of these figures is for the shampoo alone

And this repeats across the whole category, not in one odd case.

Of the four bottles that give a figure, the three which explain how they measured it measured with the conditioner on. One says so in those words, another says “used with its conditioner”, the third talks about a test after applying shampoo and conditioner.

And there is another that gives no figure but does explain its claim: it measured it with the shampoo plus a mask. Its line about smoother hair was measured with three products at once.

You buy one bottle and the number comes from two, sometimes three. That is not abusive small print, it is normal in cosmetics. But nobody tells the buyer, and it explains “it did not last what it said” better than anything else.

Very hot water takes more color out than whichever shampoo you use.

”Safe for colored hair” is not the same as “protects color”

This is the point that earns this page its place, and the one that costs most to ignore.

Two of the eight, among the most expensive and best known, promise absolutely nothing about how long your color lasts.

One only says it is safe for colored hair. All its figures are about repair and breakage.
In the other, the word color does not appear once among the benefits on its page. It only turns up in its question section, to say it is safe for color treated hair.

Safe means it does not spoil it. Preserving it is another thing. The industry sells the two as if they were one, and there are “best for keeping your color” lists that include products whose own maker says no such thing anywhere.

It does not mean they are bad shampoos. It means that if your problem is color going, those two are not built for that.

Three of the eight carry sulfates

In a category where the most searched thing is exactly the opposite.

Five state they carry none. Three do carry them, and two of those three publish it on their own ingredient list, which is the honest way.

The case worth telling separately: one of these brands publishes an article of its own recommending you choose sulfate free products, and the shampoo it recommends in that same article carries two, per the list it publishes itself in another country. On its main page it publishes no list at all.

And a reading trap, so nobody uses it backwards: one of the shampoos that does not carry sulfates has a salt on its list with that word in the name. It is not a surfactant, and it contradicts nothing. Anyone flagging it as a gotcha has misread it.

What this page is not

We have not tested these shampoos. We have no lab and no test panel, and none of the eight brands publishes a measurement you could compare against the others on equal terms.

What we did is read the eight official pages, small print included, and put them side by side. Out of that comes what this page knows: the figures on this shelf cannot be compared with each other, because each was measured with a different ruler.

And the thing no label has room for: how long your color lasts depends mostly on what color went on, and on what hair. A tone far from your base fades sooner whatever your shampoo does. The person who colors it knows that, and that conversation is worth more than any of these eight bottles.

What people ask

How long does color really last with a shampoo for colored hair?

It depends which figure you look at and what they measured it with, because they are not comparable. Four of these eight give a figure: one in washes, one in days, one in weeks and another also in weeks. Converting them to the same unit changes the whole ranking, and one of them does not say under what condition it got its own. The other four give no figure about color at all.

Do you need to use the conditioner from the same brand?

For the figure on the bottle to mean what it says, yes. Of the four that give a number, the three which explain how they measured it measured with the conditioner on. And one of those with no figure measures its color claim with the shampoo plus a mask. You buy one bottle and the number comes from two, or three. It is not abusive small print, it is normal in cosmetics, but nobody tells the buyer.

Does a shampoo "safe for colored hair" preserve the color?

Not necessarily, and here is the confusion that costs most money. Two of the eight, among the most expensive and best known, promise absolutely nothing about how long color lasts: one only says it is safe, and in the other the word color does not appear among its benefits. Safe means it does not spoil it. Preserving it is another thing, and you have to read whether the brand promises it or just implies it.

Do shampoos for colored hair carry sulfates?

Three of these eight do, and that is the surprising part in a category where the most searched thing is the opposite. Five state they carry none. Of the three that do, two publish it on their own ingredient list and the third only publishes one in another country. And watch a reading trap: one of the sulfate free ones has a salt on its list with that word in the name, which is not the same as a surfactant.

How often should you wash colored hair?

The pages barely say, and there is a curious gap there. Only one of the eight gives a frequency, and it says daily, though it says it in its question section and not in the instructions. The rest declare none. What does change between them is the number of latherings: one asks for two always, another leaves them optional for very dry hair. If your color goes fast, that frequency is set by whoever did it.

Is the expensive shampoo for colored hair worth it?

It depends what the difference buys you, and this list shows it is not always what it seems. The one explaining its figure best is a drugstore one, and two of the most expensive give no figure about color. In exchange, those two declare things the cheap ones do not: what they mean by sulfate free, how many washes a bottle gives, what product they measured with. What you buy with the difference is usually formula and detail, not a higher number.
