I had a lot of breakage as a natural - but I was wearing tiny dreads, and they strained the hair around my temples just as much as microbraids would. Since I've taken them out, the hair is starting to fill back in - it's a slow process, but it's DEFINITELY getting better, and not worse.
There are a couple of hairstyles I still won't wear because they put too much stress on my hairline - be gentle with it, and it will be good to you.
