Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Lightheadedness is very similar to pre-syncope. Pre-syncope is the immediate stage before syncope (fainting), particularly in cases of temporary visual field loss (i.e. vision getting "dark" or "closing in").
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger.

Hair-grooming syncope typically manifests as presyncopal symptoms during hair combing, brushing, braiding, trimming, curling or blow drying. [1] [2] These symptoms are followed by loss of consciousness and sometimes convulsions. [2] Migraines, abdominal pain, "feeling funny" or blurred vision may also occur before or after episodes.
