I was going to post about this earlier but I've had some issues to deal with lately and kinda been out of touch.

I've tested this thoroughly the past 2 years with no negative results. Mind you, I use waxworks everyday after blow drying.

I use a ionic hair dryer everyday, set to hot, and believe me it is ultra hot, could burn your skin if you don't move it fast enough.

I blow dry every day, this technique can be used to add body as well.

I use a Conair 1850 Ion Shine model. About 20 bucks at Walmart.

Blow away without worries. Also, this is how I achieved all the styles in my pics.

My pieces are all swisss.
