I'm a eighteen year old male college student. I know very little about dreads, but they are always something i've always wanted to do with my hair. I want to do something very similar if not identical or a tiny bit longer than the dreads in this picture. First question: How long would my hair need to be (before I dread) to get dreads these length. Second Question: What would I tell the hairdresser I wanted. So I guess I'm also asking what kind are these and what would I ask for.
Thanks for the help.
