How to use a rear camera to check the back of your head in a browser mirror

Open the site on a phone or tablet, allow camera access, then switch to the rear camera from your browser or device camera choice if that option appears. Prop the device so the rear camera faces the back of your head, use the grid to center the area, and tap freeze when the view is clear. Add the reference pin if you want to compare symmetry or track a spot between checks.

Set up the rear view first

A rear camera usually gives a sharper view than a front camera for the back of your head. Start by opening the mirror page on a phone or tablet. If the site asks for camera permission, allow it. On some devices, the browser will offer a camera choice right away. On others, you may need to switch after access is granted through the browser camera selector or site settings. Place the device so the rear camera points at the area you want to inspect. A stand, shelf, or folded case helps because your hands stay free. Turn your body instead of twisting your wrist. That keeps framing steadier and makes freeze timing easier.

Use a stable support before checking fine details.
Turn your shoulders slowly to bring the target area into view.
If permission was blocked earlier, change it in browser site settings from the help button route.

Get a usable view of the back of your head

The rear camera does not work like a hand mirror, so movement feels different at first. Make one small adjustment at a time. Shift the device a little, then pause. If you move both your head and the device together, it becomes hard to tell which change helped. Turn on the grid to keep the crown or neckline centered. If the subject looks too small, use the 1–3x digital crop. That crop can help with part lines, clip placement, or checking evenness, though image quality may look softer at higher crop levels. The white screen border can brighten your face-side surroundings, but it mainly helps nearby shadows rather than the hair at the very back.

Grid lines help keep the center of your scalp in frame.
Digital crop is useful for close checks but can look less crisp.
Use room lighting from above or behind the device for a clearer rear view.

Freeze, compare, and save when needed

When the framing looks right, use freeze so the image stops moving while you inspect details. Space also freezes or resumes on devices with a keyboard attached. If holding still is hard, pick a 3, 5, or 10 second timer, get into position, and let the frame capture itself. The reference pin is handy when you want to compare left and right placement, or watch the same area across separate checks. Drag it near a parting, hairline, bun base, or clip point. Resize it if you need a larger marker. Press P to pin or unpin it, unless a form field is active. When you want a copy, export a PNG. The file stays on your device through the normal browser save flow.

Use a timer if one hand is busy adjusting hair.
The reference pin helps repeat the same check point later.
PNG export happens only after you choose to save an image.

What happens when the tab is hidden

This mirror is built to stop the camera when the tab is no longer visible. In-memory frames are cleared at that time too. When you come back, you may need to start the camera again. That behavior matters if you switch apps to read a message or open another page while lining up the rear view. Support without an internet connection depends on browser behavior and whether the app files were cached after a successful earlier visit. Camera access while offline is not something you should count on every time. If you know you will need the mirror later, open it once while connected before you leave.

Switching away from the tab stops the camera feed.
Frames kept only in memory are cleared when the page is hidden.
Offline camera use may work in some cases after an earlier successful visit, but not always.

Open MakeupMirrorOnline on a phone or tablet and allow camera access.
Switch to the rear camera if your browser or device offers a camera choice.
Set the device on a stable surface, turn on the grid, and adjust crop if needed.
Use freeze or a timer, inspect the still image, then export a PNG if you want to keep it.

Can I brighten the rear camera view from the site?

No. The page can show a white border as a screen light, but it cannot change your device's hardware brightness from the web page.

When using the rear camera to inspect the back of your head, do not switch tabs while repositioning the phone, or the camera view will stop.?

The camera stops when the tab is hidden, and temporary frames in memory are cleared. If the rear camera view disappears during a back-of-head check, go back to the mirror tab and start the camera again before adjusting your angle..

Will the saved image always go to the same folder?

Not always. The save location depends on your operating system, browser, and download or file picker settings.
