Does hair putty/styling paste ruin flat-ironed hair?

I have with me some "L'oreal Paris New Studio Overworked Hair Putty" subtext "Styling Paste"

I'm wondering if using this will unstraighten my flat-ironed hair? I really want to style it kind of messy and disheveled, which it can't do on it's own (The person who flat-ironed it did a good job!)

If this will completely curl up my hair again, is there any other product, which I can find in any target/walmart, that will work for me?

Yes, the paste will make your hair one crazy mess! Don't do it!!! If you already have seeing your question was posted 2 days ago, I hope I'm wrong and it worked :)

I would reccomend ganier fuctis wave spray, surf's up is the actual name. Don't let the name fool you and don't follow the directions on the bottle. Spray it in your hair while it's wet , let it air dry and then flat iorn. Works like a charm! Good luck!
