Hormone Therapy and Hair Loss: What to Expect and How to Cope

Short answer: Yes some hormone therapies can cause hair thinning or loss, though severity varies by the specific medication, dose, and treatment duration.

Why Hormone Therapy Can Affect Hair

• Androgen-related effects: Hair growth is regulated by androgens (like testosterone and DHT), and changes in these hormones can cause pattern hair loss. This mechanism explains why therapies that alter androgen levels may influence hair thinning. ^[4]
• Cancer endocrine therapies: In breast cancer care, endocrine (hormone) agents are recognized contributors to treatment-related alopecia, though risk varies by drug. Alopecia risk differs across therapies, and hormone agents can be part of the cause. ^[5]
• Medication-specific side effects: Some estrogen-androgen combination therapies list hair loss explicitly among common adverse effects. Side-effect labeling confirms hair loss can occur in certain hormone pill formulations. ^{[3] [6]}

How Common Is Hair Loss With Hormone Therapy?

• Usually thinning, not complete loss: Unlike many chemotherapy regimens that can lead to full hair loss, hormone therapy more often causes mild-to-moderate thinning. Regrowth and texture changes are possible over time after treatment ends. ^{[1] [2]}

• Address other causes: Thyroid issues and androgen excess can contribute to hair thinning; evaluation may include TSH and androgen testing when symptoms suggest. Hormonal imbalances like thyroid dysfunction or high androgens can be part of the picture. ^{[9] [10]}
• Tailoring therapy: If hair loss is distressing, ask whether an alternative endocrine agent or dose adjustment is reasonable for your situation. Risk-benefit discussions help align cancer control with quality-of-life goals. ^[5]
