Taking Propecia – Can I Bleach My Hair?

being using minoxidil and finasteride for 3 yrs, regrown mainly fuzz, want to dye my hair bleach blonde (full head)

will this make my regrown hair fallout and damage my hair because i want to bleach it?

please advise me on what to do

Do whatever you want to do, just do the dyes with standard approved chemicals and preferably by a professional that know what they are doing. Go ahead and bleach your hair. That is a styling issue not a health one.
