The best place to begin sectioning is the front of the hair line. These sections will be the most visible so making sure they are even and seeing that they work out to have enough room is important. One of the first decisions you need to make is where to put your part. It can be smack in the middle of your head or you can have a row of dreads down the middle. Don't spend too much time on this one because in the end both ways work fine. It's more a matter of personal preference than anything else. One guideline is to follow any strong natural parts you may have

Separating sections

Sectioning you hair is an important step to making attractive dreads. It's normal for sectioning to take a while, especially if you're making smaller sections. Getting the sections right will pay off later so relax and take your time. There are two advantages to clean, even sections. They create round dreads of equal size which will lock up at the same speed and look great. Even sections will also make finding and eliminating loose hair much easier.

Your goal is to make clean sections that are as close to square as possible. This sounds easy but tedious would be a better word. First you're working on a rounded surface that's probably moving, hairlines are rarely a straight line, so close approximations and occasional compromises are sometimes necessary. Not to worry though, as long has they are the exception and not the rule the dreads will come out great.

The easiest way to section is probably row by row.
