The rule is about what hair covers, not how it is styled
No authority publishes an approved hairstyle. Down, up, braided, tied back, natural, straightened, covered for religious reasons — all of it is acceptable. What the rules constrain is occlusion: whether the hair hides part of the face that the photo exists to record.
GOV.UK states the constraint in four words for the UK: a photo must "not have hair in front of your eyes". The US manual approaches the same thing from the other direction, requiring that nothing "obscure any part of the face, hairline, or the composition of the photograph".
That difference matters more than it looks. The UK wording is about the eyes only. The US wording includes the hairline — which is why a photo that passes in one place can fail in the other with the same hair.
- Hair across the eyes fails everywhere. This is the one universal.
- Hair across one eyebrow is a US risk and usually a UK pass.
- Hair over the ears is fine. The US manual says plainly that "the ears do not have to be visible".
- Hair over the jawline or one cheek is judged on whether the face outline is still readable.
Where the crown is measured — and why volume fails
This is the rule that catches people with afros, updos, bouffants and thick curly hair, and it is almost never quoted. The head measurement does not run to the top of your hair. From 8 FAM 402.1, the State Department's passport photo adjudication manual, the measurement is taken:
| Measured from | "the top of the head (not the hairline or the applicant's hair)" |
|---|---|
| Measured to | "the bottom of the chin (not including facial hair)" |
| Required range | 50–69% of the photo's height (1 to 1⅜ in / 25–35 mm) |
| Ears | "the ears do not have to be visible" |
| Accessories | "hair clips, bobby pins, or thin headbands, are acceptable if they lie flat" |
Read it carefully. The bracket excludes two things at once: you do not measure up from the hairline, and you do not measure up to the top of the hair. You measure to the top of the skull.
The practical consequence is a trap in both directions. If you have a lot of hair above the crown and you frame the shot so the hair fills the head box, your actual head is now too small in the frame and the photo fails for being too far away. If you crop tight enough to make the skull fill the box, the hair itself gets cut off at the top of the frame — and a photo missing the top of the head fails for a different reason.
The way out is to leave visible space above the hair and let the head, not the hairstyle, sit inside 50–69% of the photo's height (1 to 1⅜ in / 25–35 mm). If the hair is tall enough that this is genuinely difficult, flattening or tying it for the photo is allowed and is the simplest fix.
Fringes, bangs and hair across an eye
A fringe is fine. A fringe that reaches the eyelashes is not, and the failure is usually invisible to the person taking the photo because they are looking at the face, not at the shadow line the hair casts.
Two things fail here that people do not expect. The first is a fringe that sits above the eyes but casts a shadow across them under overhead light — the eyes are technically visible and are still obscured, which is the wording the rule uses. Facing a window rather than standing under a ceiling light removes it.
The second is a side-swept fringe photographed at a slight angle, so it crosses one eyebrow in the frame even though it does not in the mirror. If you wear your hair swept, check the photo rather than your reflection.
- Clear of the eyes, no shadow across them — passes.
- Touching the lashes or breaking the eyeline — fails.
- Across one eyebrow — a US risk, because the manual names the hairline.
- Tucked behind one ear only — fine; symmetry is not a requirement.
Clips, pins, headbands and what counts as a head covering
There is a line between a hair accessory, which is generally allowed, and a head covering, which is generally not. The US manual draws it explicitly, and the wording is worth having:
| Allowed | "Hair accessories, such as hair clips, bobby pins, or thin headbands, are acceptable if they lie flat on the head or hair and do not obscure any part of the face, hairline, or the composition of the photograph." |
|---|---|
| Not allowed | "Hats or other head coverings, such as wide headbands, scarves, bows, turbans, and large skullcaps, are prohibited unless they are worn for medical or religious purposes" |
| If worn for religion or medicine | It "must not partially or completely obscure the face, whether directly or by shadow", and must be "of uniform color with no pattern and no visible perforations" |
The deciding words are "lie flat". A thin band that follows the shape of the head is an accessory. A wide band that stands away from it, or a bow that adds a silhouette, is being treated as a covering — which is why the same headband can pass on one person and fail on another.
GOV.UK words its version of the same rule as: a photo must "not have a head covering (unless it's for religious or medical reasons)". The religious and medical exception exists in both places; it is not a loophole to be argued for, and neither authority asks you to prove it in the ordinary case.
A new colour, a new cut, and the likeness rule
Hair colour is not a rejection reason. Neither is a dye job, visible roots, a wig, or hair that no longer matches the photo in your last passport. Nothing in either rule set constrains the colour or the origin of your hair.
What does apply is a separate requirement: the photo has to be a current likeness. The US rule asks for a photo taken within the last six months that is "a good likeness of" you; GOV.UK asks for one taken within the last month. The manual then says directly that "a photograph showing a change in hairstyle or facial hair from the identification document submitted is acceptable if it still is a good likeness of the applicant".
So a dramatic cut between your ID photo and your passport photo is not a problem in itself. A photo of you from two years ago with hair you no longer have is a problem, and it is a recency problem rather than a hair one.
Babies, toddlers and wispy hair
Infant hair fails differently. Fine hair that lies flat across the forehead reads as an obstruction over the hairline, and hair that sticks up softly makes the crown almost impossible to locate — which then makes the head height wrong without anything looking wrong.
Both are fixable at the moment of the shot rather than afterwards. Smooth the hair flat with a damp hand before photographing, and photograph from directly above with the baby lying on a plain sheet so the crown is unambiguous in the frame.
What a compliance check measures on your photo
Hair only ever fails a photo through one of three measurable things: the eyes, the face outline, or the head height. These are the checks a US passport photo is held to here, and the third one is where hair does its quiet damage:
- Exactly one face, looking straight ahead
- Head sized 50–69% of frame
- Eyes at the required height (56–69% from the bottom)
- No head tilt
- Background replaced with pure white
- Even, uniform background
- Sharp focus — no blur
- Natural exposure — not too dark or bright
The head-height check is the reason to measure rather than judge. Your head has to sit inside 50–69% of the photo's height (1 to 1⅜ in / 25–35 mm) and your eyes inside 56–69% up from the bottom of the photo, and neither is something a person can estimate reliably from a photo on a phone screen — particularly when hair volume moves the apparent top of the head away from the real one.
The check is free, needs no account, and reports what passed and what failed against each rule. If it passes, the finished file is 600×600 JPEG · 2×2 in print sheet · pure white background, with a print-ready 4×6 sheet (6 copies) if you need prints.
