To anybody like me who has naturally oily hair to the point that it looks icky if you don't shampoo every single day, this stuff:
Is awesome.
Spray it into the roots, brush it over, spray the next layer, etc. etc. etc., then blast with a blow dryer while ruffling your hand through it. Bing! Clean, fresh hair! It was super easy and the results were awesome. I'm pleased I can shampoo every other day now and not be a nasty ass because of it. It's a pain in the butt when I have to flat iron my hair every time I wash it.
