Sandra, I usually don't have the tendency to workout in the AM, but occasionally I do. If I do any cardio, no matter what time it is, I follow it with a shower, albeit a quick scrub if it need be.
My typical routine is to workout when I come home after unwinding about an hour. I get really sweaty with a lot of Cathe stuff so, I might unwind after a small meal and then hit the shower. Normally, I wash everything with a good scrub & wash my hair, but leave in my conditioner, since my hair is terribly dry. In the morning, I usually rinse it out then style as usual. If I run in the morning then I shower, shampoo then style as usual. If I showered the night before because I had worked out that same night, and then I go have an early cardio session, I will lightly shampoo my hair roots & condition after that session.
If for some strange reason I split my workouts & I only do my weights later in the day, I may not shower until later that night if I'm not to gritty.
