So, I decided to try out dry shampoo for 2 reasons. The first being that I have really dry hair and shampooing it just strips it of what little oil it has. And it makes no sense to condition the shit out of it after I just stripped it to nothing. The second reason is just a theory that I had. The thing that most effects how quickly my hair color fades has been how frequently I shampoo it. So, I thought maybe dry shampoo would extend the color life.
