I've started minoxidil about 2 weeks ago and just recently after i get out of the show and towel dry my hair i apply dr. lee's 5% xandrox. Immediately after i seem get this red rash looking thing that runs from the side of my temple, down my neck to the top of my chest. It's hard to explain, it's like blushing or something. It only happens there though, not on my whole head or neck. Are things like this normal?????
