It depends the stylist and how the stylist feels about your hair. Ana took care of my hair and I wanted her to use the new Sundryer. Instead she used a regular old dryer with a diffuser and used clips. It came out beautiful. However, when I asked her why not the Sundryer she told me that she was afraid that it may give my 3b/c a bit of frizz.
