Dry and coarse I'm cool with, but "rebellious" makes me think that my hair is a sentient being. I'm not comfortable with the notion that my hair is developing political attitudes, antagonistic opinions and a moral code.
And also, if it's for dry, coarse and rebellious hair, I shouldn't need to use it when I'm in the shower. In the shower, my hair is not dry nor coarse - it's wet and slick. And rebellious? It's going exactly where I point the shower head, punk.
... yes, I still have hair.
