Post FUE surgery, scalp is really itching and oily.

Post FUE surgery, my scalp itches and gets very oily, not sure if this is normal or not. Its been 3 months since surgery now. I wash my hair every other day with pura d'or shampoo and sometimes I wash it with a bar soap to get the oil out. I did my surgery overseas. I've never had an oily scalp before. I did what I was told by my doctor, used baby shampoo for the first month in a cup, never got aggressive with my scalp.
