Differential Diagnosis for Hair Increase Shedding

• Single most likely diagnosis
  • Telogen Effluvium: This condition is characterized by a significant increase in hair shedding due to a disruption in the normal hair growth cycle, often triggered by stress, hormonal changes, or medical conditions. It's the most common cause of diffuse hair loss and is usually reversible.
• Other Likely diagnoses
  • Androgenetic Alopecia: Also known as male/female pattern baldness, this condition is caused by the effects of androgen hormones on hair follicles, leading to thinning and shedding, particularly on the scalp.
  • Alopecia Areata: An autoimmune condition that causes patchy hair loss, which can sometimes present as increased shedding if the patches are widespread or if the condition is in its early stages.
  • Nutritional Deficiencies: Deficiencies in vitamins and minerals such as iron, zinc, biotin, and vitamin D can lead to hair shedding.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Thyroid Disorders: Both hypothyroidism and hyperthyroidism can cause hair loss and shedding. Early diagnosis and treatment are crucial to prevent long-term complications.
  • Lupus: Systemic lupus erythematosus (SLE) is an autoimmune disease that can cause hair loss among its many symptoms. It's critical to diagnose and manage lupus due to its potential for serious organ damage.
• Rare diagnoses
  • Trichotillomania: A psychological disorder characterized by an irresistible urge to pull out one's own hair, leading to noticeable hair loss.
  • Loose Anagen Syndrome: A rare condition where hair is easily pulled out, often due to a defect in the hair follicle's anchoring system.
  • Tinea Capitis (Ringworm of the Scalp): A fungal infection that can cause hair loss, redness, and itching on the scalp. It's more common in children but can occur in adults as well.
