I mainly use dry shampoo to keep my blue hair bright for as long as possible and regular washing can ruin it fast. I wanted to try something new as I didn't care for Tresemme brand dry shampoo and find it impossible to locate Algemarin brand dry shampoo in my area.
I bought got2b Rockin it mainly because it was a new brand and on sale ( I bought 2 for the price of one). I'm glad I risked it, I thought it was very effective and worked well all day. my hair, especially my bangs looked clean and dry. the smell can be a bit strong at first, it is reminiscent of a lemon scented cleanser but you do get used to it and it doesn't linger in your hair either.
you do want to make sure to spray it as directed, if you do it too closely you might find it difficult to blend in the white into your hair, especially if you have dark hair. I would likely buy it again. After months of looking in drugstores I finally have quite a few more options, so I may try those out as well.
