He had a lot of hairstyles. But if आप mean the lion mane hairstyle, well, first आप have to straight it and then आप have to aply हैरस्पे to "spike it out". I know bill used to spend about 1 can a दिन just for this.
I don't know if आप can also do it द्वारा the teasing it, but if so it would never be the same.
First आप straight it out, and then hairspray, straight the hair out, on the ways आप want it..
the secret is: straight the hair out, at the same thime आप spray it over your hair, if your हैरस्पे is "wet" when आप straight the hair, is getting hard, and आप get it like bill :)
