I think any intense heat can be damaging, but they may be better for you than the alternative. IMO you really have to abuse your hair to really cause noticable damage. I blow dry and use hot rollers- the hard plastic kind, every day and I dye my hair every couple months at home and my hair is shiny, thick and nice- I have some split ends but as long as I trim regularly it looks veryhealthy and pretty. Now my mom has really dry hair, she gets it done every 3-4wks super blonde and it's breaking off, and so damaged but she uses a curling iron on it at least twice a day and blow dries too. I think bleaching is the worst for your hair.
