Need Volumized Hair

by Vidhi
(Mumbai)

My hair is scanty and the length goes to my lower back. I have a step hair cut with 3 steps. My hair often becomes flat as I have silky black hair.

Please suggest some means which would help me in volumizing my hair and make me look better.
I usually wear a hair band to make my hair puffy, but, I need a change...Please make suggestions.
