I have used “Just for Men” hair coloring in the past and am starting on a treatment of finasteride. Could you recommend a hair coloring product, “Just for Men” or any other, that will not damage my hair or that has ingredients less likely to cause damage
Hair coloring will not affect genetic balding or damage your hair as long as you use the product as directed and it is a commercial grade product purchased from a reliable source. Taking finasteride and coloring your hair are unrelated. I don’t know much about coloring agents to advise you further.
