Val you are not alone...I feel your pain so deep right now, its not even funny. Like you I suffered severe breakage to my nape back in February. I do not use heat and have not for over a year.
When I started LHCF last march I had severe nape damage,
for some strange reason it always occurs around February(Things that make you go hmmm)...This has happened 2007,2008, and 2009...First it starting feeling sort of thin and I ignored it thinking that it had something to do with my stretch. Well, weeks later it was clearly breaking and thinning even more. About 3 weeks ago I just cut my losses and cut off the few wisps of hair off.I have a big block of nappy taco meat now from mid-ear on down and I have also started to use Nioxin. I'm chalking it up to being relaxed and decided that I'm gonna try to transition.Very scary but I need this to quit happening to me.
I honestly feel as though there is something seriously wrong with that area of my head and I don't have a resolution except for prayer and Nioxin. Hoping it works.
I wish you the best on the re-growth of your nape.
