Why doesn't my hair hold the smell of my shampoo and conditioner?

it's been like that since i was younger. right now, i use aussie and it smells amazing, but it won't keep the smell! i have thick, silky hair; but not a lot of it. and my friend uses the same shampoo and conditioner as me, but her hair can keep the smell in for days on end! i've tried aussie, garnier fructice, suave, pantene, and none work for me! when i get out the shower, it smells like the conditioner, but when it dries, it smells like hair... and i don't want to spray my hair with anything or change my shampoo and copnditioner or anything, i just want it smelling like my shampoo! help?);
