How to use repair and shine serums? - eyebrow repair

i good, so I'm a boy and my hair down to her eyebrows when I pull down. and my hair is fine. Okay, so I want my hair to be shiny, flexible and can move the whole day. And the designer said repairs and things arranged sera Shine. Its called "Design" repair and shine serum. So I do not want this cuz this little pot of $ 10.50 for it to lose its bright, soft, and able to turn around and everything. How do I apply?
