For the first couple of months i did the BS ACV wash, but due to a bit of laziness if been using quite small portions of whatever shampoo we have :P I realized could be a reason of slowing the process, but with the small amount i use i also assume that it couldnt inhibit the progress THAT much. Have you heard of shampoo causing that much of a problem? My only doubt about that is that the parts that are dreaded and quite tight.
Other then that i almost never put my hair up or wear hats or anything or even touch it much aside from separating.
I attached 1 pic, its also on my profile along with another taken at the same time. Its probably closer to 9 months then the 8 written.
EDIT: just wanna add that if not using enough shampoo isnt the problem probably cause i dont have an issue with oily hair
