Who doesn't hate seeing a hair or a speck of dust on their screen? Annoy your victim by putting a fake hair on their browser screen.

By Hair on Screen extension, you can add a digital hair to your friend's computer screen. No matter how hard he tries to remove it, he won't succeed, because it simply doesn't exist.
This is an extension that can be installed on Chromium-based browsers such as Chrome, Brave, Edge, Opera, etc.
You can install it in the victim's browser and don't pin in the url bar, so they don't know what you've done.
Plus you can set it to show as many hairs as you want, from one to as many as you want!

The bristles are light enough to look natural. They stay fixed on the screen while you scroll up and down. This extension works best on pages with a white background.
