Hair pieces can be worn between surgical visits if you want, as long as proper hygiene and ventilation of the scalp are maintained.
For the first 7 to 10 days, post hair transplant, you have to be extra careful not to disturb the transplanted grafts while putting on or off the hair piece.
After that, in case your hair system requires use of adhesive, we advise you to take care that the adhesive/tape does not rest over the transplanted area.
