I used to have a military-style buzz cut. About a year and a half ago (when I first became aware of me being TS) I decided to grow it out. Now it's just past my shoulders, very full and fluffy, naturally wavy. (Lucky genes, I guess...47yo) When I pony-tail it, the tail touches my collar.
Had one "dusting" about 8 months ago. A "dusting" is where the stylist trims *just* the very ends off, to make it all neater looking.
