FUE hair transplant 5 days ago, can I apply makeup to temple areas? Either powder or liquid form? Can I apply at back? (Photo)

Every doctor may have a different opinion on what you should do after surgery. Since you trusted your doctor for your surgery, you should contact your doctor for his/her advice.

Wait until all the scabs/crusts have fallen off of the area, which should be anywhere from a week to two weeks after the transplant.

At just 5 days it is not a good idea to apply makeup or concealers to the transplanted areas. You are still in the healing process. 

Given that is has been less than a week since your hair transplantation surgery, I would recommend being cautious about applying any chemicals to the healing grafts. At our practice, we recommend that our patients wait at least one full month after their procedure before they color, perm, or chemically treat the hair in any way. However, since cosmetics are specifically formulated to be applied to the skin, they can be safe to use as soon as your incisions (both at the graft and donor sites) are fully healed, which may be as soon as three days after your transplant. Still, as with any surgery, it is important that you discuss your concerns with the doctor who performed the procedure, either over the phone or at your next post-operative visit, before making any alterations in your recovery plan.

It is usually best to avoid make-up for a week after hair transplant.  That being said, powders work better than liquids because the little scabs will catch the make-up and make it look odd.  Use only for short periods and wash as often as possible (this will also help clear the crusting and improve healing)

As long as you can see crusts, you should not apply any make-up; however, once the crusts are gone, go for it
