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

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.
