Hair care during the rainy season

Now that the hot and humid rainy season has arrived, even when I blow-dry my hair, the flyaways on my straight hair get all frizzy and look messy. So I've been paying more attention to hair care than usual. However, it was such a hassle to shampoo, apply conditioner, wait, and then rinse it off every time during my busy morning commute. But this no-wash treatment is so good. If I spray it on when my hair is about half dry and massage it in, the frizzy flyaways are drastically reduced.
