Answer: When a hair or other thread becomes tied around a toe or finger tightly, so as to put the digit at risk of damage, the medical condition is called "Hair tourniquet." If you look under "Syndrome - hair tourniquet" in the ICD-9 tabular index,

the listings direct you to a superficial injury by site code. For a noninfected toe, you should use 917.8 (Other and unspecified superficial injury of foot and toes without mention of infection).

To identify the injury's external cause, "constriction caused by hair", you may also add E928.4 (Other and unspecified environmental and accidental causes; external constriction caused by hair).
