You change your hair...

Liam: you have always hated your hair. It was so curly and you wanted it straight. You told Liam one day that you wanted to get it perminatly straight. You also wanted to dye it. He didnt want you to but he let you anyway since it was your hair. 


Harry: your hair was brown but you did not like it. One day you told Harry that you wanted to dye it blonde. He always has loved your hair. You finally agreed with him that you would not dye it but you got it cut anyway. 


Niall: your hair was always so straight that you couldn't do anything with it. You told Niall that you wanted to get a little bit of a perm. He hated the idea of you getting it permed. He finally agreed with you that if you got your hair permed, he would be able to straighten your hair when ever he wanted. 


Zayn: you always have loved your hair. This time when you went to get it cut, you got bangs. You wanted to surprise zayn so when he came home you had a hat on. He took off your hat and he was shocked. He loved your hair before but now he loved it even more.
 Louis: your hair was blonde but you wanted to change the color. Louis didn't want you to dye your hair completely, so you made a deal. You would just get highlights. He got to chose the color of the high lights though. (sorry I ran out of ideas for zayn and Louis')
