I need help with itchy scalp after working out.

I don’t have eczema or dandruff or even lice.
I’ve never had this issue before but for some reason my scalp gets really itchy after a hard work out.
I’ve amped out my work out and so my scalp sweats a lot now and after I wash my hair it feels fine till it dries out. I also don’t want to wash my hair so much that it will dry it out further. I’ve tried to use the same shampoo my daughter uses for eczema but it does nothing for me. If anything its, drying out my hair. I’m afraid to use conditioner because I worry it may make my scalp itch more.
I don’t want to have to slow down my work out.
Would like to hear from someone who may have had this problem or at least knows someone who did.
