Trichotillomania (Hair-pulling disorder) and Excoriation (skin-picking) disorder are classified in DSM-5 under:

• A Impulse-control disorders (chapter with IED, kleptomania, pyromania)
• B OCD and Related Disorders ✓
• C Somatic Symptom and Related Disorders
• D Anxiety Disorders

Explanation

DSM-5 classifies Trichotillomania and Excoriation disorder under 'Obsessive-Compulsive and Related Disorders' along with OCD, BDD, Hoarding disorder, and Substance/Medication-Induced OCD-related disorder. They are grouped here due to phenomenological similarities (repetitive, compulsive behaviors, often ego-dystonic, difficulty resisting the urge). N-acetylcysteine has some evidence for trichotillomania, and habit-reversal training (CBT technique) is first-line psychological treatment.
