i found this product very useful as i didn't need to wash my hair instead i just sprayed from a distance and massaged into my hair, i found it very easy to use, it has a lovely scent and leaves no residue on your hair, perfect for on the go.
Does improve the appearance of unwashed hair
No powder or residue
Not as effective as a dry shampoo with powder
I usually use a dry shampoo with powder to soak up oil as I find they are the only effective ones. However, this does come a close second. I found it useful to have for when I was already dressed and didn't want to get dry shampoo all over my clothes.
