To switch on you just press and hold the black button for about 10 seconds, select desired temperature and wait until the light stops flashing. Use on dry hair. Wind hair around the the heated barrel, allow 10 seconds for the curl to form then allow hair to cool before styling. Amy has really straight hair and she was able to achieve these results on her first use of the styling wand. Amy found the finger protectors difficult to get on with so she risked removing her fingerprints and used the wand without the protector. The cool tip on the wand helped to minimise the risk of burnt fingers and I'm happy to report her fingerprints are still intact.
