Need hair advice for a child...

My 3 yo niece is going to be in a wedding. She has hair that is I guess between 3a an d 3b. Anyway, when blown straight is is bra strap length if she wore a bra -- lol

The last lady who did her hair blew it out but didn't do it properly so it frizzed like in an hour.

Should I take her to my domincan stylist? I am afraid that the dryers they use are too hot and will burn her... she is only 3. Help!!!

I think a press 'n curl would do less harm than the Dominican blow out.
