I have 3 full sized cans of Batiste Dry Shampoo and a travel size in my handbag. Firstly, it’s affordable and effective so there’s no reason not to have this in your beauty collection. I have black long, fine straight hair so when my roots get oily, it’s obvious. A quick blitz of this followed by a short massage of my scalp and I’m good to go for another day without washing my hair.
