A good moisturizing deep conditioner> a nice smooth blowdry and a decent flat iron will give you that look.
Second to a good deep conditioner, I think the biggest key is to not apply too much product after washing or you'll get that greasy heavy look. Use a light hand and apply just a bit of the leave in of your choice and a few small drops of chi silk infusion or another serum like the Fantasia IC heat protector in the pink bottle. Blow dry then lightly distribute a drop or two more of serum throughout your whole head then flat iron in small sections.
