I wear my hair in a braid every night.
Obviously that's not an option for you, but like the others said, you could just spritz your hair with water and comb it.
Overwashing will definitely make your hair thinner. Especially if you're not using conditioner. The detergents in shampoo aren't the greatest for your hair, and overusing it causes damage.
If you really like showering that much in the morning, you could just get your hair wet but not shampoo it, or use conditioner every other day.
