White Dots and White Flakes on My Head One Month Following My Hair Transplant

I had a hair transplant surgery since one month and week before (on the 20th of June), my hair is full of white crusts as shown in the photos, they exist everywhere in my hair. They are itchy and annoying. They increase with time. I wash my hair every day with a shampoo but don’t dry it to avoid hurting the grafts. I don’t know if this because of the residual of the shampoo or what. How to get rid of these white crusts please? They are very very annoying. I am afraid they affect the transplanted hair. I need your help please. I tried to contact the doctor did the surgery and didn’t reply. I am sorry for your disturbance. 

This is residual crusting and requires a more vigorous hair washing with your fingers and a good shampoo. At this time you can’t harm the grafts so be aggressive.
