Why Did My Hair Turn Orange After Bleaching? What It Means

If your hair turned orange after bleaching, the lightener most likely stopped before breaking down enough of your natural pigment, and warm tones are what is left at that stage. On natural hair the orange is not a surface stain: it is your hair, part-lightened. Blue toning shampoo can mute it; getting past it is a colourist's job.

Why did my hair turn orange after bleaching?

Because orange is what partway looks like on many darker starting shades. If you only want to calm the colour you can see, our guide to blue shampoo for orange tones covers it. This article explains what happened inside the hair: a toning problem or a lifting problem.

Lightener is an oxidiser. The ingredient lists on Fanola's own pages for its blue and violet lightening powders pair persulfate salts with sodium silicate and metasilicate, and both are mixed with a Fanola developer.

Your natural colour comes from melanin, packed into tiny granules inside the hair. Under the microscope, hair bleached three times shows those granules broken into holes and unidentified fragments; after a single lightening, one of the two studies saw very little breakdown. The evidence is thin (one colour maker's lab study, and one study apparently on a single donor's hair). The one peer-reviewed by-cycle colour series we found is low-rigour and used a single dark sample treated with alkaline peroxide, not a bleach powder: it got lighter and moved towards yellow with every cycle, staying in the yellow-red range. One lightener patent maps the result by starting shade: light brown lightens towards yellow, medium brown towards orange, dark brown towards reddish-orange. That is a manufacturer's model, not a measurement.

Does bleach really go red, then orange, then yellow?

As a rough guide, yes; as a precise ladder, nobody has measured it. People believe in fixed stages because hairdressing education and lightener patents describe them, and a dermatology review repeats that dark hair passes through "red to orange to yellow".

The evidence is narrower. Our research notes found no measured red-to-orange-to-yellow sequence on hair. The single measured series shows a drift towards yellow, but it started almost colourless-dark, so it can neither confirm nor rule out a red phase. Our research also found no independent study tying hairdressing "levels" to a physical measurement. So read orange as "not lifted far enough for the result you wanted", not as an exact level.

Is the orange left-over red pigment that bleach cannot shift?

Maybe, but it is far less proven than it sounds. Hair holds two kinds of melanin: eumelanin (brown-black) and pheomelanin (yellow to red). The popular story is that bleach destroys the dark kind first and the warm kind resists. Lightener patents state it without data, and a 2014 dermatology review calls pheomelanin "probably" more resistant to chemical bleaching.

The primary evidence is one 1987 Clairol study, whose peer review we could not confirm, using one brown-haired and one red-haired donor and judging melanin by colour change alone. It did find the dark pigment easier to bleach. But the same authors favoured a different cause for the red shift in bleached brown hair: pigment particles breaking up and scattering less light, not surviving red pigment. That view rests on tests on films of cuttlefish-ink melanin rather than hair. Which cause dominates is not established, and in practice it does not matter: either way the warmth is inside the fibre, and toning can only mute it.

Which orange-hair beliefs hold up?

What does the blue in a lightener actually do?

It targets what you see, not how far the hair lifts. Fanola's page for the No Yellow Color Blue Lightener lists "contrasto dei riflessi arancio" (countering orange reflections) among its results; the violet version's page says its pigments neutralise unwanted yellow. On both, the only colourant in the ingredient list is CI 77007, ultramarines. In the patent literature, one maker gives concealing a red cast as a reason to tint lightener, and our research notes found no study measuring tinted against untinted powder at the same lift.

These are professional products. Fanola's directions say to wear disposable plastic gloves through mixing, application and rinsing, keep the product off the scalp for highlights, and keep checking the hair's condition. Colourists will find both in our lightening collection.

Purple or blue: which one cancels orange?

Blue. Fanola positions violet against yellow, and its Wonder No Orange shampoo against orange reflections on light brown hair. Fanola's Italian ingredient list for it names Acid Violet 43 alongside CI 42090, a blue dye; the English page says "blue pigment". One trade textbook, Milady, explains it with the colour wheel: opposites cancel to a neutral brown or grey. Muted is not lighter. No independent study has tested that mechanism on hair. The violet side is covered in how purple shampoo works.

Our listing for Fanola Wonder No Orange Shampoo 350ml says to massage it into wet hair, leave 1 to 5 minutes, rinse, and use twice a week; Fanola's Wonder No Orange page says the range's pigments work gradually. Fanola tells you to wear suitable gloves with its No Yellow shampoo, and we would do the same with this pigmented one to avoid staining hands and nails. See No Orange versus Wonder No Orange.

Can you bleach again to get past the orange?

Not at home. Fanola's "up to 7 levels" is a stated maximum, not what your hair will do in one sitting; other brands publish figures up to "9+", that one for off-scalp use only. We found no independent study measuring lift per session on real hair, and none establishing a safe gap between sessions.

The damage is real whatever shade you end up. Bleaching converts cystine, the sulphur bonds that hold hair together, into cysteic acid, and in an early industry study wet strength fell. In a 2026 industry-authored combing test on one hair source, once-bleached hair shed about three times more fragments than untreated hair.

When is orange hair a salon job?

Whenever it needs more lift, which covers most solid orange. Also when it is patchy or banded, and when hair is breaking, has been henna'd, or sits more than a couple of levels from your target. Soft warmth on otherwise light hair is the one case a blue shampoo handles well between visits.

Common questions

Will purple shampoo fix orange hair?

No. Fanola positions violet against yellow, and orange needs blue, which is why it sells a separate Wonder No Orange line for light brown and blonde hair. Even blue only mutes orange. Toning shampoo deposits pigment and cannot lighten, so solid orange from under-lifting needs further lightening by a colourist, not a different coloured shampoo.

Why does my hair go orange again a few weeks after toning?

Toner is colour over a warm base; as it fades, the base shows. Fanola says its Glow & Glossy toner lasts up to 15 to 20 washes. Light may add to it: in one Schwarzkopf lab study (peer review not confirmed), lightened brown hair yellowed somewhat more than untreated hair over four weeks of light. Toned hair was untested.

Will orange hair fade back to my natural colour?

No study reports bleached-out melanin forming again, so lightening is treated as permanent, though that is an inference rather than a measurement. Nothing in our research shows the warm residue washing out either. What fades is any toner on top. Plan on toning to mute the orange, or further lift to remove it.

Is orange hair a sign my hair is damaged?

Not on its own. Bleaching damages hair whatever shade it leaves: it turned sulphur bonds into cysteic acid in an early industry study, and, in one industry-authored lab test, made hair shed more fragments when combed. Judge condition separately from colour. If hair snaps or feels weaker when wet, talk to a colourist before any further lightening.

Always follow the instructions supplied with the product. Do the allergy or patch test the pack asks for, and if you are unsure about a colour service, especially one involving lightener, speak to a professional colourist.
