After several years of short hair, my hairstylist convinced me to start growing it back out. And as long as I'm growing it, I figure I might as well go long. I haven't really decided what I will do once I get there. Partially, I just want to see how much of a pain it is to blow dry, style, etc. Partially, I'm thinking I'll grow it out long enough to donate and then go short again. Who knows?
Based on the last time I grew it back out, I figure it will be another year to year and a half before it stops growing, usually just past midway down my back. Two years in, what's one more?
