2. Not all hair ties are created equal

Erasers are cheap but harmful.

Silk or satin hair ties reduce friction and are much better for curly, dry, or fine hair.

Hair bands (e.g. Invisibobble) prevent hair from creasing and tugging.

3. Sleeping with your hair tied tightly is a bad idea

It puts pressure on the hair roots and over time can lead to thinning.

If you must tie your hair up at night, use a loose hair tie and avoid putting it in high ponytails.

4. Hair bands can cause “traction alopecia”

Constantly pulling your hair back forcefully (especially wearing the same hairstyle every day) can lead to a type of hair loss caused by tension on the scalp.

5. Hair ties harbor bacteria

Like makeup brushes, they can collect dirt, oil, and bacteria, especially if you frequently carry them on your wrist.

They should be washed and replaced regularly, especially after training.

6. They are often an emotional or nostalgic item

Many people keep hair ties nearby—in their purses, on doorknobs, in their cars—and they often carry a strange, comforting sense of familiarity.

Some people wear them as a subtle accessory or out of habit, rather than for functionality.
