Hello , i was told that i could use any shampoo after 12 days post op. I put sebamed anti hairloss shampoo without massaging it and rinse my head. İmmediately after that i got burning sensation on my skin and there was readness which all gone after 20-30 minutes like stated in the instructions. Fallowing days i switched to sebamed everyday wihtout any problem. i might be getting a little bit paranoid but my concern is that Sebamed Anti Hairloss shampoo could have done any harm to my grafts ?.
