Dermarolling / Microneedling / Re: Itchy scalp after rolling for Minoxidil
« on: April 30, 2013, 04:37:55 PM »"Common side effects of minoxidil include burning or irritation of the eye, itching, redness or irritation at the treated area"
"Alcohol and propylene glycol present in some topical preparations may dry the scalp, resulting in dandruff and contact dermatitis.[7] Some formulations of minoxidil substitute lipid Nanosomes in order to reduce contact dermatitis from the alcohol and propylene glycol vehicle.[8][9]"

Dermarolling highly enhances the absorption of Minoxidil and that likely increases its side effects but the main problem is the alcohol or the other substances that the Minoxidil formulation contains, not dermarolling or your dermarolling technique.
