Are any chemicals in Got2b glued product bad for your hair?

I'm a 24 year old male who just likes to look good and just recently was introduced to a new hair product from a friend of mine. In the past I havn't bleached my hair or use excessive amounts of jel or hairspray. Neither do I apply any heat to my hair for any reason. I have no lice or dandruff and just basicaly use shampoo and conditioner every day. So I bought myself some Got2b glued and freakin loved the stuff!! But after a while I felt my scalp have a burning sensation but went away after maybe 20 minutes, I just told myself my hair isn't use to that stuff but maybe if I use it more there will be no more problems. So I kept using it for maybe 3 weeks and the burning was still going on, not only that but I noticed my hair in front (because I use it more in front to spike) was becoming thinner and was also somewhat losing some of that hair!!! I seriously was becoming a little bald in front!! I immediately stopped and started using better natural gels like American Crew and since then no problems or thinning hair or baldness. I did some internet research and there was this website warning you about some of the chemicals in the Got2b glued gel but it didn't say what or why. Can anyone help me? Any info would help, thanks.
