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