I am a 55 year old man considering a hair transplant. Is there a benefit in taking Propecia a few weeks before and after the procedure? Will it result in a greater success rate of transplanted grafts? Also since I have lost the hair I am going to lose already, would there be a benefit in continuing the Propecia long term? Thank you so much Dr R.

You really should pose this question to your doctor (who has examined you and has a treatment plan for you). I don’t know enough about your hair loss history to be able to give you an idea about your possible successes, but in general, Propecia can be good for the crown and top areas with or without a hair transplant.
Propecia can diminish the risk of shock hair loss from a hair transplant surgery, but less so in a 55 year old. Everyone is different and every doctor has a different opinion, as there is no rule.

While the timing of your hair loss beginning may sync up with the start of your medications, I really cannot say for sure if the two are related. It’s possible that it was coincidental timing, and that there is another underlying issue. A partial list of causes for hair loss in women can be found
I would see a doctor about the nose bleeds and eye irritation. Certain substances can cause irritation to your eyes, but I cannot say if Toppik is the cause. If you’re getting Toppik in your eyes, perhaps another camouflage might do better for you, such as DermMatch.
