My hair cannot seem to grow past the nape of my neck. Every time it gets to about that point it starts to thin out. I keep my hair moisturized at all times. It is not dry nor do I have major split ends(just a few). I am not sure what is up here? It grows but thins out so much that I end up having to cut off inches equivalent to my new growth so for the last couple of years I have gotten no-where with my hair. My hair is currently long enough that my ponytail is about 5 inches long but thin, thin, thin so wearing a ponytail looks funky. Any ideas??? Suggestions???
