Hair Loss in Men
Hair loss in men is common. Genetics is a major factor in male pattern baldness, but thyroid disease, stress, illness, iron deficiency, and nutritional issues can also cause shedding.
Symptoms
Receding hairline, thinning at the crown, diffuse shedding, and changes in hair texture.
Causes and risk
Male pattern baldness (androgenetic alopecia) is most common. Thyroid disease, low iron, stress (telogen effluvium), and medications are other important causes.
How it is evaluated
Evaluation depends on the pattern and includes a review of medications, nutritional status, thyroid labs, and iron when diffuse shedding is present.
Treatment
Treatment depends on the cause. Options include topical medication, oral medication, PRP therapy, and hormone-based treatment when indicated.
When to seek care
Seek care for sudden or patchy hair loss, diffuse shedding after illness, or hair loss with other hormonal symptoms.
