Mollski:
three ways really:
1) Grow your hair long, section it off and then backcomb it nice and tight, dont use wax or beeswax or toothpaste or whatever the internet tells you, be prepared for it to shrink shorter or not look like its growing at all for ages.
As your hair continues to grow the knots will be tightening hence the appearance of it getting shorter or not growing. To keep the roots of the dreadlocks tight and less fluffy: use a teatowel and press firmly against your scalp… then rub it in small circles (pick a direction – clockwise or anti-clockwise and stick with it… by rubbing in the opposite direction you'll undo your good work)… this circling will break the odd hair at the root and tangle it into the dreads.
let them grow, buy a bigger phone book for all the new ladies you'll be collecting.
2) From short hair: have your hair braided in the smalled braids you can achieve.. all over your hair. you'll look stupid for 2-3 months as it grows out… but all the hair that grows out from under the braids will be growing into dreadlocks that are already tight and natural with no wax etc.

once the dreadlock part of the hair is 3inches long, cut off the braids from the ends.

3)grow your hair long, dont brush it, wash it regularly in a cycle but with cheap shampoo only (less perfumes and addatives left on your scalp and hair). as it starts to knot up rip it into smaller sections. follow the advice above re wax and rubbing the scalp…

whatever you do…. dont use wax, dont use conditioner, dont forget to wash your hair once you feel its tight enough not to fall apart.
hope that helps dude
