How much does it cost to simply have a hair transplant where the edges of my hairline are?

You are 36 days post op you can wear anything type of head covering (hats, bandanna, beanies)  you would like and cause no harm to your transplanted hair. YOur exercise activites can resume to normal as well. 

I wrote to you yesterday privately about this. If you used it after 5 days when the wounds were sealed, the peroxide should have no impact on the hairs in the graft.

I do not recommend using peroxide on healing tissue after having a hair transplant.  It is unlikely that you have caused damage. 

Bending your head does not cause grafts to pop out. If this is an issue you would be the first.  Follow up with your doctor for a recheck.

If you are concerned about medication overdose you need to contact your doctor.  You may also have an allergic reaction or a skin infection.  

8hrs is a good rule of thumb.  That is certainly within the framework of a grafting procedure, even if it takes all day.  The more critical factor is to ensure that the grafts are kept hydrated.  If they dry out, they won't last long at all!
