Yes heat can do damage. Personally I focus on managing that. So like when I hit it with medium heat for 1 or 2 seconds I’ll leave it and move. And then I’ll do a cold pass.

Also when showering you’ll want to keep it on warm, not hot. And finish with cold. Also for your skin. Doesn’t have to be annoying cold, but just to cool your skin and hair down.

Think of the heat as being stored in it and you have to remove it again, and you don’t want to get it too hot.

You might wanna look up some info on that if you really wanna know. This hairdryer was 13 euros and an Airbnb guest bought it because she needed it. She had beautiful long hair.

Note that spray bottles can suck. You’ll probably wanna get one from a beauty store.
