Bests & Worsts Reviews from Amazon

I only want 2 things out of life. Or at least out of my dry shampoo. 1) It must remove the dirty hair smell. No exception. This product does so without masking it with a flowery, perfumy, aroma (I'm looking at you Batiste). 2) The product needs to actually absorb and whisk away the oils on my scalp without just providing a place to hide so that the oil is still there but incognito, thereby weighing my hair down and still feeling gross. So far this is the only product that gets me through MOST of the day. If I use is at 6am, I'm good until about 3pm before I start to feel gross again. I envy those who can go more than 1 day without washing their hair. Tell me, what do you do with all of the spare time? Write novels? Fight crime?
