I was getting a hair cut and a lot of hair was falling i got some in my mouth short hair what do i do?

Spit: Not a problem.... You'd have to eat a lot of hair to cause a real problem.

Just spit it out: Of your mouth. Next breath. Breath in slowly ; deeply through your nostrils. Fill your lungs with air (but not to the point of discomfort). Hold for a count of five then slowly begin to exhale through an open mouth. Repeat at least 12 times, longer if you need to.

Nothing: The swallowed hair will be broken down by digestive enzyme snd the stomach acid. Don't worry!
