There’s a pretty simple step by step here:
1) soak your hair in the hottest water you can handle
2) scrub your scalp and dreads with the shampoo
3) rinse out all those bubblies!
4) massage in the removal conditioner (do not rinse out)
5) starting at the bottom of your locks, pick out the knots using the pick on a (preferably) metal tail-comb for a couple inches, then comb smooth
6) work your way up the dread to the root

TIP: hair is elastic when wet, and more maneuverable. Put some conditioner in a spray bottle and add just enough warm water to not clog the nozzle. Use this to keep your hair wet during the removal process!
