How to have soft straight hair?

Hi I'm a 15 year old Asian male. I'm trying to grow my hair longer like that of Korean pop stars but my hair just isn't working with me. I want it soft and smooth and straight and manageable but my hair is like so hard and it doesn't shine and its not as straight as you'd want it to be. I use conditioner everyday, wash it down with cold water and all. So I need some advice to get my hair to this texture http://hairstyles-img.co.cc/images/gc/Asian_layered_hairstyle_with_long_side_bangs_dark_black_hair.jpg because it currently looks like this http://www.mensgroominguk.co.uk/images/man_thick_hair.jpg but less flattering. :( I know it genetics has a big factor in this but I refuse to be completely enslaved by it. I want something to make it better. I don't think I can do all those rebonding or relaxing stuff for my hair. I just need some tips or pointer on how to improve my hair quality.
