Osis "Dust It" by: Schwarzkopf
If you want volumnuous hair, or if you want to skip a wash, use this. I always shampoo everyday, but sometimes if I want to wear my hair up and need extra oomph this works wonders. It is a mattifier so it absorbs oil, but a lot of people freak out over the way it makes their hair feel.
The motto I live by: The Higher the Hair the Closer to Heaven...and if a head full of product is the price to pay for pretty hair, then so be it. :)
