Solomon asch's findings on conformity might best be used to explain why

I believe the answer is; adolescents follow fads in dress in hairstyle

In his experiment, Solomon asch found that people's tendency to comform will rises if they're group with people that put pressure toward other members if they feel that they're doing something 'wrong'.
This could be reflected to things such as pressure to change hairstyle and clothing, pressure to do risky behaviors, etc.
