How can i get bill's hairstyle? i straitn it, but i cant seem to get it all wild like his.

He had a lot of hairstyles.
But if あなた mean the lion mane hairstyle, well, first あなた have to straight it and then あなた have to aply ヘアスプレー to "spike it out". I know bill used to spend about 1 can a 日 just for this.

I don't know if あなた can also do it によって the teasing it, but if so it would never be the same.

HairSpray alot of it.....

well do あなた have layered hair like his?

First あなた straight it out, and then hairspray, straight the hair out, on the ways あなた want it..

the secret is: straight the hair out, at the same thime あなた spray it over your hair, if your ヘアスプレー is "wet" when あなた straight the hair, is getting hard, and あなた get it like bill :)
