Shampoo after hair transplant - 3 weeks post-op.

Hello,Washing your hair after a hair transplantation is an important step for restoration.  We usually have our patients start spraying hair with lactated ringers with liposomal ATP as well as other growth factors twice a day to help your hair process start ASAP.  Actual hair washing usually takes place several days after the procedure.  There are several advantages to this approach:

It is best to contact your doctor about post operative care and instructions since each doctor has a different regimen.

At 3 weeks you can use any shampoo that you have. If it is the shampoo your doctor gave you and you have more of it, use it, Otherwise any good shampoo will be fine

You could go back to your normal hair care routine including using a normal shampoo since it has already been more than 2 weeks after your hair transplant. Consult your doctor for any further suggestions.
