As noted above, I wrote much of this section.  I'd always assumed that uniform dreads required special attention, which is why I wrote the section as I did.  Not so.  A good friend of mine with extremely impressive, voluminous, long dreads of perfectly uniform size never did anything to hers  no sectioning, no twisting  nothing.  And I deleted the disheveled bit, because it is unnecessary and offended someone a while back.  The conclusions one may draw from seeing dreads is a purely subjective one.
