I have washed my hair ever day since day 3 with baby shampoo and a cup while taking a bath and the scabs are still persistent. Without being able to lightly massage shampoo in my hair and work out the scabs I won't be able to get all scabs out.
In my OP I was referring to the "big wash" as the first time you are allowed to touch your scalp to work out scabs, clean better, etc.
It appears some doctors are okay with more rigorous washing by day 10, however my doc has advised to wait until 14 days.
