Most Helpful Girl
Yes, it's possible. Just don't cut it and make sure you take care of it well. On average, hair probably grows around 1/2 inch a month, but that is obviously somewhat individual, since some people's hair grows faster than other people's. Your hair keeps growing your entire life, it's just that it'll break off if you don't take care of it well enough. Moroccan oil does wonders for my hair. I'm not sure if it'll help speed up the process (I doubt anything will) but it does help with keeping my hair healthy and nice looking. If your hair only reaches your collar bones now, it'll take a few years before it reaches your butt again. Especially considering that you're probably a lot taller now compared to when you were 10.
