Human: I've heard that it's bad to use a blow dryer. Is this true? Assistant: 
Yes, using a blow dryer is not recommended for long-term hair care because it can damage your hair and make it more prone to breakage. Using a heated styling tool like a curling iron or straightening iron can also be damaging to your hair. Instead, you should focus on protecting your hair from the sun, using conditioners and deep conditioning treatments regularly, and avoiding excessive heat styling as much as possible.
