Trichotillomania

Trichotillomania is a body-focused repetitive behavior (BFRB) characterized by the recurrent pulling out of one’s own hair, resulting in noticeable hair loss. Patients experience an increasing sense of tension immediately before pulling or when attempting to resist, and pleasure, gratification, or relief when pulling.

Etiology is multifactorial, involving a complex interplay of genetic, neurobiological, and environmental factors. It is frequently associated with heightened stress and anxiety. Genetic predisposition is suggested by familial clustering.

Dysfunction in the cortico-basal ganglia-thalamo-cortical (CBGTC) circuit, particularly in the anterior cingulate cortex and striatum, is implicated. This leads to impaired motor inhibition and sensory processing, reinforcing repetitive grooming behaviors.

Lifetime prevalence is estimated at 0.6% to 4.0%. Onset typically occurs in early adolescence (ages 10–13). While females are more frequently diagnosed (3:1 to 10:1 ratio), prevalence differences may reflect healthcare-seeking behavior.

• Family history of BFRBs or OCD.
• High stress or trauma.
• Co-occurring psychiatric conditions (anxiety, depression).
• Female gender.
• Early childhood behavioral problems.

A. Early Symptoms

• Increased tension prior to pulling.


• Minor thinning of hair.


• Repetitive playing with pulled hair. B. Common Symptoms


• Irregular hair loss patches (e.g., "bizarre" shapes).


• Scalp burning or tingling.


• Feelings of shame or social withdrawal. C. Advanced Symptoms


• Complete alopecia in specific areas (brows, lashes, scalp).


• Trichobezoars (hairballs in the gastrointestinal tract). D. Emergency Symptoms


• Intestinal obstruction symptoms (nausea, vomiting, abdominal pain).

Inspection reveals uneven hair shafts, "short stubble," or "corkscrew" hairs. Skin may show excoriation or crusting.

A. Clinical Assessment: DSM-5 criteria (recurrent pulling, unsuccessful cessation attempts, distress).
B. Laboratory Testing: Generally unnecessary unless complications suspected.
C. Imaging Studies: X-rays for suspected trichobezoars.
D. Functional Tests: Not applicable.
E. Biopsy Findings: Scalp biopsy shows "catagen" phase hairs, empty follicles, or perifollicular hemorrhage.
F. Genetic Testing: Not clinically indicated.
G. Differential Diagnosis: Alopecia areata, tinea capitis, obsessive-compulsive disorder.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Identify secondary infection or anemia due to poor nutrition.
Expected Findings: Normal unless secondary issues exist.
Interpretation: Negative results rule out systemic medical causes of hair loss.

Abdominal CT/Ultrasound
Purpose: Detect Trichobezoar.
Typical Findings: Intraluminal mass in the stomach or small intestine.
Clinical Importance: Identifies Rapunzel Syndrome or intestinal obstruction.

• Alopecia Areata: Smooth, round patches without hair breakage.
• Tinea Capitis: Fungal infection with scaling and broken hairs.
• OCD: Hair pulling is typically triggered by obsessions rather than the act of pulling itself.

• Permanent hair loss due to follicular damage.
• Trichobezoars requiring surgery.
• Psychosocial impairment and depression.

A. Lifestyle Modifications: Habit reversal training (HRT), stress management, mindfulness.
B. Preventive Measures: Keeping hands busy (stress balls), wearing gloves at night.
C. Medical Treatment

• SSRIs (e.g., Fluoxetine): Manage co-occurring anxiety.


• N-acetylcysteine (NAC): Glutamate modulator; primary pharmacological adjunct.


• Atypical Antipsychotics: Used for treatment-resistant cases.

Chronic but manageable. Early intervention in adolescence yields better long-term outcomes. Many experience waxing and waning patterns.

Early behavioral therapy is the most effective preventative measure to stop cycle progression.
