I've been undergoing IPL hair removal on my face for about 18 months (treatments are about every 4-6 weeks) and I have noticed the hair on my head thinning for the past year. Researching side effect of Minoxidil (Rogaine) I found that some people suffer from unwanted hair on their arms, chest, and face. I guess my question is, if Minoxidil stimulates unwanted hair growth on untreated parts of your body, can IPL treatment trigger hair loss on untreated areas? Are hair follicles somehow related?
