Rosie, have you tried wearing your hair in a style that lets you leave it alone? I had your length early 2007 and decided to do the hard C&G challenge. In June 2008, I undid a couple of braids and pressed that section to see if my hair shines w/o products when pressed.
I was shocked at how much progress I had made. I'ma bore you with that pic coz I absolutely love reliving the excitement of that discovery!
So I went from
this in Feb 2007 to
this in June 2008 thanks to braids. Of course I'm probably still at that June 2008 length today
But that's not the point.
The point is, when I wore braids and left my hair alone, it grew. So maybe you could try that. The surprise is well worth the wait. (Note to self: I need to go back to braiding. :scratchch ) And CountryGal, I braided all the way to the ends. Way beyond my own hair.
