Hello. Thanks for writing to us at healthcaremagic It is possible that you have developed mild irritation to topical minoxidil that you have been using. This happens because minoxidil is available in an alcohol based liquid, therefore can cause irritation and some scaling as well at the site of application because alcohol is drying. If I was the treating doctor I would have asked you to temporarily discontinue minoxidil for a few days (may be 3-5 days) and let it subside. If itching is bothersome, you may use an OTC oral antihistamine e.g cetrizine 10 mg once daily for a few days. Use a gentle cleansing shampoo. Once itching subsides, you may restart minoxidil applications, but at a reduced frequency initially e.g once a day rather than twice daily. I would suggest that you discuss in more detail with your doctor regarding this. Your treating doctor may also start you on oral finasteride 1 mg once daily in addition to minoxidil. Finasteride is approved for Androgenetic Alopecia and is known to arrest further progression of alopecia Regards
