People with hair-pulling disorder use their hands to tear the hair off or cut it off with scissors, called trichotillomania, or they may chew or eat the hair they pluck off, called trichotillomania. In extreme cases, this behavior can lead to hair stone intestinal obstruction syndrome (Rapunzel syndrome, the name taken from the Grimm’s fairy tale of Rapunzel, named because the stagnant hair ball in the digestive tract will extend from the stomach to the small intestine or even large intestine), and even death. Because the percentage of patients indicating the condition is so low, some patients may feel that they are the only ones with this problem. So how do you check if you are suffering from hair breakage fetish? Forced hair plucking Patients forcibly pluck their own hair by hand or with objects such as iron clips and tweezers. The plucking site is fixed for the same patient, but it varies from patient to patient. Most of them are found in the frontal, frontotemporal and occipital hair, but eyebrows, eyelashes, axillary hair, etc. can also be involved. Repeated plucking After plucking, the regenerated hair is still repeatedly plucked, and there is often a large area of hair loss on the scalp, shaped like baldness, but the border is often uneven, and there are often residual hairs and broken hair in the area of hair loss. Older patients deny their hair-pulling behavior. The hair-pulling behavior often occurs while resting in bed, reading, watching TV or doing homework, and the symptoms are sustainable or intermittent.
