My skin and hair get EXTREMELY oily and nasty during the summer. How can I clean up the oil?

My skin and hair get EXTREMELY oily and disgusting during the summer, especially in the corners of my nose, on my scalp and the ends of my hair. I've tried putting toothpaste on my zits, but that hasn't helped and my skin STILL feels oily and disgusting. After I work out, my hair feels REALLY sweaty and covered by disgusting oil, even if it's been JUST A DAY since I've washed it last. The problem gets WORSE if it's humid outside. My skin and hair always feel nasty and oily. My hair isn't normally oily, but it pumps out the oil in the summer. I use over-the-counter acne products for my skin and I use a shampoo for dry hair because my hair is dry. I don't use gel for hold, I use hairspray or conditioner instead. How can I kick the oil to the curb FAST?
