Wearing tight man buns daily can cause what’s called traction alopecia. This is hair loss around the front hairline, caused by constant pulling on the hair by tight and heavy hairstyles. Ideally, you’d want to mix up your hairstyles, so it’s not always pulling in the same way. Try braids or a low pony instead. While you can rock the man bun daily, try not to wear it too tight, and take it out overnight to give your scalp a rest.
