Hair in dreams carries identity and vitality, echoing myths from Samson onward. Long, healthy, shining hair reflects confidence, strength and freedom of self-expression. Cutting your own hair can mean consciously letting go of an old image and choosing renewal.
Hair falling out, by contrast, tends to voice fears of losing strength, control, attractiveness or health — worries about how time and stress are wearing on you. Someone else cutting your hair against your will may signal a person trimming your power or voice. Notice who holds the scissors.
