This dry shampoo is great for when you haven't washed your hair in more than 2 days and need a quick fix to soak up the oiliness or when you just need some extra volume - and let me tell you, this collagen enriched formula is amazing. Even though I love it and would sing praises about it, this particular dry shampoo (Volume) does leave me feeling like there's some sort of film on my hair. Overall though, I love it and would definitely recommend it to anyone who has flat, lifeless hair.
