I can't figure out, what the best hairspray/gel is for holding up a four-five inch tall mohawk. I want long lasting results. It keeps falling over after about three hours. It's only about two inches wide, if that makes a difference.

I've always found that AquaNet Extra-Hold hairspray will hold almost anything up, and it's really cheap for a gigantic spray can.

This brings back fond memories, as the first question I ever asked on the net was this exact question. How do you keep up a 5 inch mohawk. Met a lot of great friends by asking that question.

By the way experience taught me that Bed Head works great. it was in a bottle shaped like a figure 8 ( or similar to Jessica Rabbit) We used it on wet hair and blow dry to set the stiffness. held up great, much better than hair spray

Yep....and use a hair dryer on low to dry the hairspray into a lacquer. You're dealing with a spikehead from the 80s hardcore scene. You're in good hands.

Awesome answers. Thank you all so much for the help. Now I'll finally get it to stay up!
