Do You Have Long Hair?

I have always wanted long hair but it never seems to get past my shoulders; by that time I need to have it cut. I try to only get it trimmed so the dead ends disappear and well, supposedly that helps to keep hair healthy.

Do you have long hair? If you do, how did it get so long? Genetics - hair growth shampoo - vitamins? Miss. Independent seems to have the same problem I do, her hair only seems to grow so long and then it's time for a trim!
