I have an oily skin with dandruff in it, i had itching all over my scalp where i had first sitting transplant, i used shampoo 3times (used normal saline to loosen the scabs) and the scabs with shaft fall off, next day the other sitting hair also fall off but this time i shampooed 4times and used intermediate force; around 300shafts fall off, did i do something wrong.. I am greatly worried..
