Earwax Colour Guide — What Does the Colour of Your Earwax Mean?
Earwax colour ranges from pale cream to black, and each shade carries clinical information. Some colours are entirely normal; others signal infection, impaction, or a condition that needs medical attention before any removal is attempted.

Why Does Earwax Change Colour?
Earwax — or cerumen — is produced by two types of glands in the outer third of the ear canal: ceruminous glands (modified apocrine sweat glands) and sebaceous glands. The secretions from these glands combine with desquamated skin cells, hair, and environmental debris to form cerumen. The resulting colour depends on three variables: the age of the wax, the ratio of glandular secretions to skin cells, and your genetic cerumen type.
Fresh cerumen is pale yellow or cream-coloured. As it ages and migrates outward along the canal wall, it oxidises — the lipids and proteins react with oxygen, progressively darkening the wax from amber through brown to very dark brown or black. This is the same oxidation process that turns a cut apple brown. The speed of this darkening depends on how quickly wax migrates outward, which is driven largely by jaw movement during chewing and talking.
"Cerumen is a normal product of the ear canal and serves a protective function. Its colour and consistency vary widely between individuals and are largely determined by genetic factors."
The most important genetic determinant of earwax colour is the ABCC11 gene. A single nucleotide polymorphism (SNP) in this gene determines whether you produce wet-type cerumen (yellow to brown, sticky, higher lipid content) or dry-type cerumen (grey, flaky, lower lipid content). This is not a health distinction — both types are normal. The gene variant is inherited and cannot be changed by diet, hygiene, or environment.
Colour becomes clinically significant when it falls outside the normal oxidation spectrum — particularly green (infection), blood-tinged (trauma or perforation), or when very dark wax is accompanied by hearing symptoms. The colour guide below sets out the clinical meaning of each colour, its common causes, and the appropriate response.
Earwax Colour Chart — Clinical Reference
Each colour is classified as Normal, Monitor, or Seek Advice based on its clinical significance.
Fresh, recently produced cerumen. This is the most common colour in people with wet-type earwax and indicates healthy gland activity.
Common Causes
- Normal ceruminous and sebaceous gland secretion
- Wet-type ABCC11 genotype (dominant in European and African populations)
- Recently migrated wax that has not yet oxidised
What to Do
No action required. This is the expected appearance of healthy, recently produced earwax.
Older wax that has oxidised and accumulated skin cells. Still within the normal range. The most frequently seen colour in clinical practice.
Common Causes
- Oxidation of lipids and proteins in cerumen over time
- Accumulation of desquamated epithelial cells
- Normal ageing of wax as it migrates outward
What to Do
Normal. If hearing is unaffected and there is no discomfort, no treatment is needed. Softening drops can help if the wax feels full.
Heavily oxidised, older wax — often associated with impaction. The darker the wax, the longer it has been in the canal. Dark brown wax is frequently found in patients presenting with muffled hearing.
Common Causes
- Prolonged accumulation without natural migration
- Hearing aid or earplug use blocking outward migration
- Reduced jaw movement (common in older adults) slowing self-cleaning
- High cerumen production rate exceeding the canal's self-cleaning capacity
What to Do
Consider professional removal if accompanied by muffled hearing, a feeling of fullness, or tinnitus. Olive oil drops for 5–7 days before an appointment will soften the wax and improve removal outcomes.
Black earwax is almost always very old, deeply impacted wax that has undergone extensive oxidation. In rare cases, it may indicate a fungal infection (otomycosis), particularly if accompanied by itching and a powdery texture.
Common Causes
- Extreme oxidation of long-standing impacted wax
- Otomycosis (fungal infection) — particularly Aspergillus niger, which produces black spores
- Blood from a minor canal abrasion that has dried and mixed with wax
- Prolonged use of hearing aids in a high-humidity environment
What to Do
Book a professional assessment. Black wax from oxidation can be removed by microsuction. If otomycosis is suspected (itching, powdery texture, no improvement after softening drops), a GP or ENT referral is needed before removal.
Dry-type cerumen, determined by the ABCC11 gene. Grey, flaky wax is the normal presentation for approximately 30% of the global population — predominantly East Asian and Native American individuals. It is not a sign of illness or poor hygiene.
Common Causes
- Dry-type ABCC11 genotype (recessive allele)
- Reduced lipid content in cerumen compared to wet-type wax
- Normal variation — not caused by diet, hygiene, or environment
What to Do
Normal for dry-type individuals. Dry wax can still accumulate and cause impaction, particularly in hearing aid wearers. Olive oil drops are less effective for dry wax; microsuction is the preferred removal method.
Very pale or white wax can indicate a high proportion of desquamated skin cells relative to glandular secretions. It may also appear white when wax has been partially dissolved by water (post-swimming or showering) and then dried.
Common Causes
- High skin cell content relative to lipid secretions
- Water exposure partially dissolving and then drying the wax
- Dry-type cerumen in its earliest, least-oxidised state
- Rarely, keratosis obturans — a condition where keratin accumulates in the canal
What to Do
Usually normal. If white wax is accompanied by significant hearing loss, pain, or a history of repeated impaction, a professional assessment is advisable to rule out keratosis obturans.
Orange earwax sits between fresh yellow and older brown on the oxidation spectrum. It is a normal transitional colour as cerumen ages and accumulates skin cells.
Common Causes
- Intermediate oxidation of wet-type cerumen
- Mix of fresh secretions and older, more oxidised wax
- Normal variation in ceruminous gland activity
What to Do
Normal. No action required unless accompanied by hearing changes or discomfort.
Blood in or around earwax always warrants investigation. The most common cause is a minor abrasion of the canal wall — often from cotton bud use — but it can also indicate a perforated eardrum, a ruptured blood vessel, or, rarely, a tumour of the ear canal.
Common Causes
- Canal wall abrasion from cotton buds or other objects
- Tympanic membrane perforation (eardrum rupture)
- Barotrauma (pressure injury from flying, diving, or a blow to the ear)
- Ruptured blood vessel in the canal wall
- Rare: glomus tumour or squamous cell carcinoma of the ear canal
What to Do
See your GP promptly if you notice blood in your earwax. Do not attempt to remove the wax yourself. If accompanied by sudden hearing loss, severe pain, or dizziness, seek same-day medical attention.
Green earwax is not a normal colour and almost always indicates bacterial infection — specifically the presence of Pseudomonas aeruginosa or other gram-negative bacteria, which produce green-pigmented pyocyanin. It is a classic sign of otitis externa.
Common Causes
- Pseudomonas aeruginosa infection (produces blue-green pyocyanin pigment)
- Other gram-negative bacterial otitis externa
- Rarely, a foreign body that has become infected
What to Do
See your GP before booking earwax removal. Active otitis externa is an absolute contraindication to both microsuction and irrigation. The infection must be treated first with antibiotic or antifungal ear drops.
The ABCC11 Gene — Why Your Earwax Type Is Inherited
The single most important determinant of your earwax colour and texture is a gene you were born with — not anything you eat, do, or fail to clean.
Wet-Type Cerumen (ABCC11 dominant allele)
Wet-type wax is sticky, yellow-to-brown in colour, and has a higher lipid content. It is the dominant form in European and African populations — approximately 97% of people of European descent carry the wet-type allele. The higher lipid content makes wet wax more adhesive and more prone to accumulation, particularly in hearing aid wearers.
Dry-Type Cerumen (ABCC11 recessive allele)
Dry-type wax is grey, flaky, and has a lower lipid content. It is the recessive form, found in approximately 80–95% of East Asian populations and the majority of Native American populations. Dry wax is less adhesive but can still accumulate, particularly in narrow canals or hearing aid wearers. Olive oil drops are less effective for dry wax because there is less lipid to dissolve.
The ABCC11 gene also determines axillary odour — people with the dry-type allele produce less body odour and typically do not need deodorant. This connection was first described by Yoshiura et al. in Nature Genetics (2006) and has since been replicated across multiple population studies. The gene encodes an ATP-binding cassette transporter protein that regulates the secretion of lipids and steroids from apocrine glands — including the ceruminous glands of the ear canal.
Colour Is a Guide, Not a Diagnosis
Earwax colour provides useful clinical information, but it does not replace a proper assessment. The same dark-brown wax might be a straightforward impaction in one patient and a sign of a more complex issue in another. NICE NG207 requires a full clinical history and otoscopic examination before any removal — colour alone does not determine treatment.
At Earwax Removal Devon, Eleni examines both the colour and the consistency of wax, the state of the canal wall, and the appearance of the tympanic membrane before deciding on the appropriate removal method. Certain ear histories change what is safe — a green or blood-tinged wax may require GP assessment before any removal is attempted.
The most reliable indicators for professional removal are symptoms: muffled hearing, a feeling of fullness, tinnitus, or earache. Colour is a supporting signal — not the primary decision-maker.
Red Flags by Colour
Green or yellow-green wax with itching and discharge
GP before earwax removal — likely bacterial otitis externa
Blood-tinged wax after no obvious trauma
GP promptly — rule out perforation or canal pathology
Black wax with powdery texture and severe itching
GP or ENT — possible otomycosis (fungal infection)
Any wax colour with sudden complete hearing loss
Same-day GP or ENT — may be sudden sensorineural hearing loss
Dark brown wax with muffled hearing over weeks
Earwax removal appointment — impaction is the most likely cause
Grey flaky wax in a hearing aid wearer
Regular microsuction — dry wax accumulates in hearing aid canals
Frequently Asked Questions
Answers to the most common questions about earwax colour and what it means for your ear health.
Is dark earwax a sign of poor hygiene?
Dark earwax is not a sign of poor hygiene. The colour reflects how long the wax has been in the canal and how much it has oxidised — not how clean your ears are. People who clean their ears frequently with cotton buds often have lighter-coloured wax simply because it is newer, but cotton bud use pushes wax deeper and increases impaction risk. Dark wax in someone who never uses cotton buds is entirely normal.
Why does my earwax change colour over time?
Earwax darkens as it ages because the lipids and proteins in cerumen undergo oxidation — the same process that turns a cut apple brown. Fresh wax is pale yellow; as it accumulates skin cells and oxidises over weeks or months, it progresses through amber, brown, and eventually very dark brown or black. This is a normal process and does not indicate illness.
I have grey, flaky earwax. Is something wrong?
Grey, flaky earwax is completely normal and is determined by your ABCC11 gene. Approximately 30% of the global population — predominantly people of East Asian or Native American descent — produce dry-type cerumen. It is a genetic trait, not a sign of illness, dehydration, or poor ear health. Dry wax can still cause impaction, particularly in hearing aid wearers, and microsuction is the preferred removal method.
What does green earwax mean?
Green earwax almost always indicates a bacterial infection — most commonly Pseudomonas aeruginosa, which produces a blue-green pigment called pyocyanin. This is a classic sign of otitis externa (outer ear infection). Earwax removal is contraindicated while an active infection is present. You should see your GP for antibiotic ear drops before booking any removal procedure.
Should I be worried about black earwax?
Black earwax is most commonly very old, heavily oxidised wax that has been in the canal for a long time — often seen in patients who have not had professional removal for years. It can be safely removed by microsuction. Less commonly, black wax with a powdery texture and severe itching may indicate otomycosis (fungal infection), particularly Aspergillus niger. If softening drops do not change the appearance after a week, a GP assessment is advisable before removal.
Can earwax colour tell me if I need professional removal?
Colour is one indicator, but not the only one. Dark brown or black wax suggests older, more compacted cerumen that is less likely to migrate naturally — making professional removal more appropriate. Green or blood-tinged wax requires medical assessment before any removal. Grey or pale yellow wax may be perfectly healthy. The most reliable indicators for removal are symptoms: muffled hearing, a feeling of fullness, tinnitus, or earache.
