What is red nail theory - and should you try it?

Red nails have always had a reputation - bold, classic, and slightly dangerous in the best way. But thanks to social media, they’re not just a manicure choice anymore. There's something called red nail theory: the idea that painting your nails this fiery hue can boost confidence and maybe even pull a little extra attention your way.

The theory leans on psychology and nostalgia. Red triggers memories, signals energy, and, yes, turns heads. Think of it as a micro-expression of power dressing. Only instead of a blazer, it’s a swipe of polish. Some say it taps into childhood associations or cultural ideas of glamour and attraction. Others just love how it looks.

Does it work? Maybe, maybe not. But if wearing red nails makes you feel more confident, it’s already doing the job. Consider it less of a trend, more of a reminder that the smallest detail - like your nail colour - can change how you carry yourself.

And sometimes, that’s more than enough.
