i started doing cardio work-outs again about two months ago. I've noticed my hair has started to look pretty crap ever since. it must be the intense perspiration as on my weeks off my hair looks ok again. what i wanted to ask is if profuse sweating is bad for your hair, and if there is anything that can be used on the hair just before working out to minimise the problem. i don't like using conditioners as it leaves my hair looking limp.
