By making more (and thus, thinner) sections.

The size of a finished dreadlock depends on a) the size of the section, b) the tightness of backcombing, and c) hair density / thickness.

Consider your lifestyle and your new dreads' need for maintenance - to keep your dreads looking good, particularly for the first six months to a year - you'll need to palm roll every single one at least once a week, preferably more often.

We suggest having a good old fashioned think about how long this can take - to do 120 dreads carefully, it can easily take more than 45 minutes - and make sure you're up to it.
