How to photograph your own hairline

Last updated August 4, 2026 · Written by the Crown team

A hairline photo is a measurement, and a measurement you cannot repeat is not a measurement. Five variables do almost all the damage. Fix them once, write them down, and never think about them again.

You do not need good photos. You need identical photos. A slightly unflattering photo repeated exactly is worth far more than a great photo you can never take again, because the whole value of tracking is in the difference between two frames — and any variable you did not control shows up in that difference pretending to be your hair.

The five variables, in order of how much damage they do

1. Light direction

   The largest single lever, and the one nearly everyone gets wrong. A ceiling light rakes down through the front of your hair and prints a shadow onto the scalp behind it. That shadow reads exactly like a gap. Move two feet and it moves too.

   Do this: face a window on an overcast day, or face a lamp at roughly eye height. Light coming from in front of you fills the hair instead of raking through it. Overhead bathroom light is the worst common case, and it is where most people take these photos.

   Then: write down the room and the light. Same room, same light, every time. That sentence is your protocol.

2. Chin tilt

   The second largest, and completely invisible to the person doing it. Tipping your chin down rotates the top of your head toward the lens and exposes more scalp; tipping it up hides it. A few degrees is enough to move a reading.

   Do this: eyes level with the lens, looking straight into it, head not tilted. If you can see your own ceiling in the frame, your chin is down.

3. Distance and lens

   Phone cameras have more than one lens, and the widest one exaggerates whatever is closest to it — at arm's length, that is your forehead. Switching between the ultra-wide and the main lens between two scans changes the geometry of your face, not your hair.

   Do this: use the main lens (usually 1×, not 0.5×), stay at the same distance, and frame it the same way: head filling the frame, forehead fully visible, top of the head just inside the top edge.

4. Hair state

   Wet hair clumps into separated strands and shows scalp between them. Product changes how light bounces off it. Pushing your hair back and pushing it forward are two different hairlines.

   Do this: dry, and in one fixed state. For most people the most repeatable choice is dry, unstyled, brushed the same direction. Whatever you pick, pick it once.

5. Timing in your routine

   Hair sits differently straight out of bed, straight out of the shower, and six hours into a day. This matters less than the four above, but it is free to control.

   Do this: same point in your routine each time. Most people find "after it has dried, before anything is put in it" easiest to repeat.

The trick that beats all five

When you take the next photo, put the last one on screen and match it. Look at where the top of your head sat in the frame, how your ears lined up, which way the light fell, and reproduce it. Matching against a reference image is far more reliable than remembering a protocol, and it fixes the tilt problem, which is the one you cannot feel.

If your phone lets you, take it with the rear camera in a mirror rather than the front camera. The rear sensor is better on most phones, and the mirror gives you a live view so you can match the framing while you shoot.

Turn off anything that smooths

Beauty filters, skin-smoothing modes and heavy portrait processing are actively destructive here, because the fine detail they smooth away — individual strands at the border — is the detail being measured. If your camera app has a beauty or smoothing setting, switch it off before the first photo, not the third.

Avoid portrait mode as well. The blur it applies has to guess where your hair ends, and it guesses wrong exactly at the boundary you care about.

A protocol you can actually keep

That is a sixty-second routine. Run it once a month, not once a day — hair changes over months, and scanning more often than it changes only measures your lighting.

What Crown handles and what it doesn't

Crown's capture step guides the framing and checks two things on the phone before anything is sent: whether the frame is too dark to read, and whether there is a head in it at all. After the scan it tells you per zone whether the zone was readable, and if not, which angle would have fixed it.

What no app can do for you is the light and the tilt. Those happen before the shutter, and they are yours. Get those two right and everything downstream gets more honest.

The crown shot is a genuinely different problem — you cannot see the thing you are photographing. It has its own guide.
