The first time I used this. I pumped a quarter size amount and that was too much. I have medium length hair and just under a dime size is more than enough to control your hair. The scent is sweet almost like a mild perfume. I use it to tame my "fly-away" hair especially during humid weather. It's is also very good if you want to have that sleek shiny look, but as I said before, use very little at a time.
