As you know I shaved all my hair off Jan. 13, 2008 and it's been four months, I measured my hair and it's 2 inches, hair grows on average 1/2 per month, so I guess I am right on par, which means I will have 6 inches at the end of the year, YAY ME, 6 inches is a great length, 12 would be better, and since they say hair grows faster in the summer, I might luck into 8 inches at the end of the year instead of 6 inches
