Perfect for someone like me, a busy Mum who doesn't always have the time in her days to wash my hair in the shower, (when I really should have) it is a perfect solution! Easy to apply just spray to roots of your hair and run your fingers through to disperse product evenly and... TA-DA! No more oily roots, its amazing. I've been using the Tropical Scent, and I love it, reminds me of summer and drinking Malibu on the beach.
It typically has lasted about 1 and a half days after applied then I would wash my hair normally.
Overall, would recommend it to anyone who doesn't have time to wash their hair, or someone who has to wash their hair everyday to give your poor scalp a break.
