Eyebrow Plucking and Sneezing: Debunking the Myth

Plucking eyebrows does not cause sneezing. The sneeze reflex is triggered by irritation of the nasal mucosa (trigeminal nerve → sneeze center in lateral medulla). Eyebrow plucking stimulates the ophthalmic branch of the trigeminal nerve (V1) in the forehead/supraorbital region, which is anatomically distinct from the nasal branch (V2).

Why the Myth Persists

• Facial nerve interconnections can cause referred sensations.
• Coincidental timing: plucking may coincide with pre-existing nasal tickle.
• Photic sneeze reflex (ACHOO syndrome) affects 18–35% of people; bright light during plucking could trigger it.

Actual Risks of Eyebrow Plucking

• Folliculitis, ingrown hairs, hyperpigmentation
• Corneal abrasion if instrument slips
• Over-plucking → permanent thinning

If you experience sneezing with eyebrow grooming, it's likely coincidental or due to light exposure—not the plucking itself.
