Hair growth

My last relaxer was June 2011. That's about six months ago. The back of my hair is totally natural and my husband just measured a pulled curl at 2 1/2 inches. That's just the back. The top is a little longer although there are still some relaxed ends up there. At this rate my hair should be 5 inches long in the back once I reach a year (June 2012) and perhaps 10 inches long after two years. I'll keep my fingers crossed.
