Hair usually grows about half an inch a month. It will enter a stage where it will stop growing and fall out, and another strand will take its place after 2-3 years (however every follicle is different). It's taken me about 14 months to grow my hair out 7-8 inches without cuts or trims. If you're going to grow your hair out, you really want to avoid trimming it. Contrary to popular belief, cutting the ends will not cause your hair to grow faster (but it will make your hair look healthier). I was told yesterday by classmates and my teacher in my cosmetology class that I have a girls haircut. It's shoulder length and in layers.
