Reknowned child psychologist Bruno Bettelheim addresses this specific issue in his seminal work The Uses of Enchantment. Bettelheim found that nearly 55% of children under the age of five exhibit heightened fear in haircutting situations that involve exposure to shears. Only 10% of those whose hair was cut with electrical shavers showed a measurable increase in fear. Pairing these observations with analysis of the children's dreams, Bettelheim determined the presence of a Jungian archetype Shears, an anthropomorphic scissor-like creature that appeared in children's dreams and snipped off their genitalia. Although the children themselves did not bridge the gap between dream and reality, their subconscious kicked into gear when they were were exposed to the barber's shears, resulting in a reaction of heightened fear.Why are some infants and toddlers afraid of haircuts and some arent?
They don't cry because they think it'll hurt...they cry because they're in an unfamiliar/uncomfortable situation. It's the same thing with doctor visits...some kids act like it's no big deal...and some are terrified.





Also...I've seen some ADULTS in hair salons, especially women with long hair who are literally panic stricken when the stylist picks up the scissors...I've seen women cry when they get their hair cut because they think that too much will be cut off. I never understood that because...heck...it'll grow back...but it happens.
Irrational fears have no reason.
