Hair tourniquet
Hair or thread constricts a body part, causing pain and swelling.
Hair tourniquet is a medical condition in which a strand of hair or thread becomes tightly wrapped around a body part, most commonly a toe, and occasionally a finger, genitals, or other areas. It causes pain, swelling, and can lead to tissue death due to lack of blood flow. The condition is rare and primarily affects children around 4 months of age, though cases have been described in older children and adults.

Lore & Background
The condition occurs most often accidentally. The mechanism is believed to involve wet hair becoming wrapped around a body part and then tightening as it dries. Diagnosis involves examination of the entire child. In some cultures, thread is tied around the penis of children with bedwetting or for luck.
Reader's Guide
Hair tourniquet is a rare but important condition to recognize in infants, as early detection prevents severe complications like tissue ischemia, urethral damage, or autoamputation. Treatment involves cutting or dissolving the ligature; chemical depilatories such as Nair can be used if the hair has not cut into the skin, but are ineffective on nylon or other fibers. Loss of the toe is extremely rare, and rubber bands can have the same effect. Prevention strategies include caregiver education, tying back maternal hair, inspecting clothing for loose threads, and turning infant garments inside out before laundering.
