hey girl , i use to do the same thing not knowing i was causing such damage, i stop the scratching around my edges, i eventually found out about a product called mtg and began using it, it has really helped my hair grow around the edges, its grown all the way back, i also dont brush the areas, i dont use a brush at all, i dont apply heat to my edges and i massage my scalp everynite, when coming i part my hair into sections when the new growth is heavy
hth
