3 weeks after hair transplant I am having rashes on my forehead and other part of face?

It is best to contact your doctor about post operative care and instructions since each doctor has a different regimen.It is VERY IMPORTANT to inform your doctor about any side effects.

Hi Kumar Naresh, thank you for posting your question. Rashes
can be a symptom of an allergic reaction. They may not be only confined to the
face. You might also have them on your torso as well. The finasteride could be
causing this but allergies to finasteride and/or the binding agents are not
common.  There could be a photosensitive
reaction to medications or even a Latex allergy. I do not feel strongly about
any of these possibilities as the symptoms did not appear until 3 weeks after
your procedure.  It may more likely be from
something which you may have been exposed to more recently.

You may have Post-finasteride syndrome, occurs in men who’ve taken finasteride to treat hair loss by a chance of %4-5. That may causes some symptoms include: loss of libido, erectile dysfunction, depression, suicidal ideation, anxiety, panic attacks, Peyronie’s disease, gynecomastia, muscle atrophy. The condition often has a life-altering impact on victims and their families, such as job loss and the breakup of marriages and romantic relationships..

I would first look to medications that you might be taking that could cause a spontaneous allergy thaat might prresent this way, Go back and see your surgeon and ask him/her
