Well, do research on what you can get in Singapore that's similar to Got2bGlued Spiking Cement. Any hair product that can give you a radical hold strength needed to do a punk rock spike head look should work.

Also, the shampoo is whats making you itch; I never shampoo with the unit on my head; I daily rinse with lukewarm water, fully soaking my head & rinsing out the styling product. I blot dry gently, then comb & let air dry.

A soap or shampoo residue dryed on your skin will make you itch like mad
