I can't say I do cold showers, but I generally rinse my hair with ice cold water after conditioning it - so that's how my shower ends... I guess its pretty much the same thing but just for a shorter period of time haha! It really is a great wake up call and since I have recently taken up an exercise regime in the mornings, the cold burst after a workout is great too! Its an invigorating way to kick off the day, that's for sure!
