L67.0
Trichorrhexis nodosa
Clinical Classification Guidelines
Medical Intelligence & Overview
Trichorrhexis nodosa is a hair disorder characterized by weakened hair strands that tend to break easily, resulting in hair that appears brittle and frayed. This condition affects the structure of the hair shaft, leading to visible nodules or swelling along the hair fibers. While it is generally a cosmetic concern, understanding its causes and symptoms can help in managing the disorder effectively.
Causes & Symptoms
Clinical Causes: Repeated mechanical trauma from brushing, combing, or hair styling that causes hair weakening. Exposure to harsh chemical treatments like relaxers, dyes, or bleaching agents that damage the hair's keratin structure. Environmental factors such as excessive sun exposure or pollution that weaken hair over time. Nutritional deficiencies, particularly lacking in proteins, vitamins, or minerals essential for healthy hair growth. Underlying scalp conditions or skin disorders that compromise hair integrity. Genetic predisposition influencing hair strength and resilience.
Key Symptoms: Brittle, fragile hair that breaks easily at various points along the strand. Presence of small swellings or nodes along the hair shaft, often visible under a microscope or magnification. Hair that appears frayed, with a 'split' or 'frayed' appearance at break points. Reduced hair length due to frequent breakage. Hair strands may seem thinner or uneven because of repeated breakage.
Diagnostic & Treatment
Diagnosis Path: Diagnosis is typically based on clinical examination and microscopic analysis of hair samples. A healthcare professional examines a hair strand under magnification to detect characteristic nodes and frayed areas typical of trichorrhexis nodosa. Additional assessments may include reviewing the patient's hair care routines, exposure to chemicals, nutritional status, and medical history to identify contributing factors.
Treatment Protocols: While there is no specific cure for trichorrhexis nodosa, management focuses on minimizing hair damage and promoting healthier hair growth. Recommended approaches include:
