To sign "blow dry" or "blow-dryer" just mime using an "L" hand as if it were a
blow-dryer.
I personally don't get much use out of this sign.
BLOW DRY / BLOW-DRYER / HAIR-DRYER:
For the "verb" form do the sign a bit larger = blow dry.
For the "noun" form, do the sign smaller and use a sign like MY or YOUR before
the sign and don't use the puckered lips. Example: MY BLOW-DRY WHERE? =
Where is my blow-dryer?

Also see: HAIRDRYER [it is the same sign]
