In order to get my hair looking similar to this (I dont want it longer since it difficults my training at the gym), which is layered btw, to look like this, which products would you guys recommend? I was thinking of hair wax but, since I have used it before when I had shorter hair, to put a textured and segmented effect on my hair. But now that it is longer I will have to use more and I am afraid that it will get so greasy that it will require a emergency bath after a few hours of use.
To get your hair like that, first you will have to visit a salon for that type layer cut. Take the picture with you, and ask the stylist what the best thing to use would be. I am guessing that he/she will recommend a mousse of some sort added before blowdrying or a light gel that lets your hair have some movement without being "crunchy." It looks like a cool style, not too long, but not short either. That model's hair was probably worked on for a good while though by some stylists before the photo, so don't expect miracles every morning to happen for you. It's funny how when one leaves the salon with perfect hair, it never comes out like that the next day when one does his hair for himself.
