I suggest using something with heat protector in it if you are going to do a lot of ironing, I use thermasilk for this its cheap (I use a lot of expensive stuff and really makes very little difference for this) and works awesome. I've never had personal experience with your hair products and don't know their ingredients so I can't be very helpful.
I suggest looking on the site http://www.makeupalley.com - www.makeupalley.com they give reviews of all beauty products, so you can look for the one that best suits you, and see what real people say about it. Or try Paula Begoun http://www.cosmeticscop.com/ - http://www.cosmeticscop.com/  she tells if you if the basic ingredients in your products do anything, or they're just high priced gimmicks.

 

You are not supposed to flat iron, blow dry, bleach, vegeterian/low iron, do full dye job whatever. But I do all that stuff all the time :) Just counteract with a reconstructor (strength), conditioners (moisture), glosses/clear color (shine). My motto: what is healthy hair, hair is dead, I can do anything I want to, to it, including making it look "Healthy"

 

If your nervous about doing this stuff on your own. Hair salons often have reconstructor or glossing treatments that you can ask for.
