Hello Doctor
could shampoo mixing cause problems ? . I would like to wash a first hand with a cheap shampoo before applying my medicated shampoo ( for seb derm )
Thank you
No, it shouldn’t cause any problems. That is, unless you use a baking soda shampoo followed by a vinegar shampoo… causing a volcano on your head. Sorry, bad joke. Wouldn’t the medicated shampoo by itself be fine though?
