Trends on TikTok are endless. After the theory of red nails, now the "theory of white nails" is spreading. What does white nail polish mean?
In theory, it means you're single and maybe looking for love (or sex).
Pink or purple hues are also said to mean you're talking to someone, but still ready to flirt. Shades of blue indicate you are in a relationship.
No one really knows where or why the white nail theory started, but surely girls who are not single will now think twice about white nail polish.
