Find a stylist you trust, tell them you want to grow your hair out. They'll help you get an initial shape, and while it's growing, it's still important to get trimmed up. It takes time, and in the middle stages can look a little messy, but it all comes together in the end.

Also remember a little bit of styling can go a long way during those awkward lengths. Sometimes it really is all in how you wear it.

You actually need to get a few parts cut. All of your hair grows at the same rate so you will have to get cuts on the front parts Every few months.

Just make sure to go to a proper hair stylist. I went to a cheap one once and they, despite my INTENSE PROTEST, cut everything :/

I just yolo'd it through the mullet phase, then once it was long enough I trimmed everything to the same length.
