Does the Accelerator work when used alone? - Dreadlocks FAQ's
The Locking Accelerator will speed the formation of knots and help your dreads tighten when used by itself, but using it after washing your dreads with DHHQ Dread Soap will multiply it's effects noticeably. This is because truly clean hair that is free from residues can be reached and acted upon directly by the Accelerator since there are no residues coating it. This allows the Accelerator to be much more effective.
You generally want to apply the Locking Accelerator right after the hair is washed while it's still damp. Finish up by drying the dreads with a hair dryer.
