1.  Hinata's hairstyle has changed significantly, but her forehead protector remains constant. This raises the question of what she would look like with it on her head.

2. Affecting Combat Abilities: Hinata's clan specializes in close combat, but wearing the protector on her head would make it vulnerable to being knocked off. Losing it is disgraceful for a ninja.

3. Symbolism and Value: The headband holds significant meaning.

Itachi Uchiha marked a slash on his protector to signify pain and regret, while Neji's loss of his marked his death.

4. Neck Protection: The forehead protector is indestructible and wearing it around the neck could protect against sneak attacks on the neck.

5. Oversized Head: Hinata's childhood depiction shows her with an oversized head. Imagining her with the forehead protector on her head accentuates this feature, creating an unattractive image.
