Clinical Causes: Use of hormonal medications such as anabolic steroids and androgenic agents. Certain antidepressants and antipsychotic medications. Medications used for high blood pressure, including beta-blockers. Chemotherapy drugs targeting rapidly dividing cells. Medications for thyroid disorders, including thyroid hormone suppression therapy. Other pharmaceuticals that alter hormone levels or function.

Key Symptoms: Gradual thinning of hair on the scalp, chiefly at the crown and frontal areas. Noticeable increase in hair shedding, especially during washing or brushing. Reduction in hair density, leading to visible scalp through thinning hair. Possible patchy hair loss in some cases. Preservation of hair on the sides and back of the scalp in most instances.

Diagnosis Path: Diagnosis is primarily based on a detailed medical history and physical examination. Healthcare providers may inquire about recent medication use and onset of hair loss. In some cases, blood tests are performed to evaluate hormone levels and exclude other causes of hair loss. A scalp biopsy can be considered if the diagnosis remains uncertain, helping differentiate drug-induced alopecia from other types of hair loss.

Treatment Protocols: The primary approach involves discontinuing or switching the offending medication under medical supervision. In some cases, hair regrowth may occur spontaneously after stopping the medication. Supportive treatments such as minoxidil can promote hair regrowth and slow further hair loss. Patients are advised to maintain overall scalp health through gentle hair care routines. Addressing underlying health issues and consulting with healthcare providers can help develop a personalized management plan.
