    Great for fine, thin hair!

    I love this for my very fine and thin hair. Not heavy and gives my hair some bounce!

    this is a must!

    My favourite hair product for thin hair with no volume. I bought another volumizing product for extra umpf from somewhere else but it was more expensive and didn't have the same effect and texture as this one. The texture is very natural. I usually run it from root to tip the blow dry my hair upside down to 'activate' that lift, i used to not like my hair that much, but now i love it!
