I love having one at home and one in my handbag for throughout the day.
I get very oily hair or when theres a little more moisture in the air I feel like it really weighs my hair down given an awful appearance.
This is a life saver! I just spray underneath the top layer of my hair to prevent the obvious white look and then ruffle my hair to get it through the roots before brushing out.
I have only just tried a brunette version but really think I prefer the standard. Smells great too.
