Does hair cement ruin your hair?

Most hair cements such as Spike It and Got2Be have polymers in them. That is how they make your hair so stiff. Unfortunately, hair cement isn't good for your hair but it will not ruin it to the point of not fixing. I wouldn't advise using a lot for a long period of time. I use it for Halloween hair but other than that I try to stay away from it. Try like a Pravanna Hardening Fiber Paste.
