Corticosteroid and Propecia

Good Day Dr. Rassman,

I am a male in my early twenties and suffering from genetic hair loss. I was wondering if applying a topical Corticosteroid like Clindamycin 2% in Gen-Clobetasol for treating my scalp irritation would have any negative impact if I start taking Propecia? Also, is there any data available showing the benefits of using a shampoo like Nizoral or Neutrogena T-Gel while on Propecia?

Thank you for providing this service, I appreciate your time and expertise in responding to my questions.

You should not be experimenting with drugs. Clindamycin is an antibiotic and using strong steroids can have a balding side effect. To my knowlege there have been no clinical studies showing synergistic benefits of using special shampoos and Propecia.
