Of course, there's the red nail theory. Then, along came the came the light blue nail theory. But what about the black nail theory? Black nails make women on TikTok feel more chic, confident, and empowered. For instance, @biryanibby_ — a TikToker with over 16,000 followers — posted a video sharing her reaction to getting her first black manicure. The TikToker said, "I feel so cool doing things. I feel kind of, like, powerful. It matches everything... it's just such a vibe... I think the black is the new French or the new red... I love it."

Viewers agreed, commenting, "Ugh love me some black nails," and "They look great on you!" Unlike some other "nail theories" involving bright or light colors, the black nail theory isn't about using nail polish to flirt with men or appear classically attractive. The black nail theory is about making the women who wear the nail polish feel powerful — not the men looking at those women.

TikTokers think black nail polish intimidates men

Many TikTokers have a theory that black manicures scare away men, and there's even a post explaining the concept. TikToker @janell.roberts shared a video rocking black nails, with her voiceover saying, "Forget the red nail theory. Have you heard about the black nail theory? It is the perfect male-repellent. Stay over there." Viewers agreed, commenting, "Heavy on the repellent" and "Yesssss black is deadly and comforting." Another commenter even noted another spin on the theory, suggesting that black manicures help wearers increase productivity. After all, how could you not be more productive when men aren't constantly bothering you and getting in the way?

Other TikTok users, such as @journeyof.janae, proudly post videos showing off black manicures with the same audio, appearing confident and enjoying their nails. Even men have confirmed that the theory is true. TikToker @IEInFriends shared a video where a man gave his opinion on women based on their choice of nail color. When the other man asked him what he thinks of women who wear black nails, he said, "Don't f**k with them. They'll eat your soul. They hate men." Viewers commented, "Black nails for life," and "Me with my fresh black nails."
