I wasn't too thrilled about this product, my hair does get oily a day after washing it.. I sprayed some to my roots a day after washing it, and it did take away a little shine, but not completely, after a few hours I was back to square one! The upside though, the smell is pleasant :)
I wouldn't be buying this product again, I don't think it's for people who have really oily roots or hair gets oily quick!
