3 weeks post FUE, can I let shower head stream hit inplanted area now? What kind of shampoo can I use now? (photo)

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.   After three weeks you can shower (wash your hair) normally.

By now your grafts are well rooted in the recipient area so you should be fine to shower and gently massage the top of your head. I usually recommend higher quality sulfate free shampoos as they won't  contribute to drying out your skin as much. 

At this point the grafts are securely incorporated into the scalp and pressurized showering will not injure them.Organic shampoos are nice to use but really anything will suffice.Please check with your surgeon regarding hair washing instructions.

you can start to your normal life and do everything, including every kind of activity, smoking, close contact sports so on. You may wash your head  just like before operation how often and which shampoo you use.

At this point you can shower normally with whatever shampoo you usually use. Unless your surgeon has said otherwise there shouldn't be any issue with hair products in general.

After the first week it should be okay to shower and wash your hair as you did prior to the procedure.  However, I would suggest you contact your surgeon to assure you are following his/her preferences.

After 3 weeks you can shower normally.  The grafts should be secure. Any good shampoo will work but be gentle using your finger tips on the recipient area
