What Are the Main Reasons for Hair Fall in Men?

Male pattern hair loss commonly produces gradual thinning at the temples, hairline or crown because follicles become more sensitive to androgen signals. Telogen effluvium can cause diffuse shedding after illness, major stress, weight change or another trigger, with the change often noticed later. Alopecia areata may present as smooth, sharply defined patches. Scalp ringworm can add scale, itch, inflammation or broken hairs. Tight styles, extensions or repeated tension can contribute to traction alopecia.

The location, speed of change, scalp appearance and family pattern help a clinician separate these possibilities. Hair fall itself does not identify one diagnosis.

Photograph the hairline and crown in consistent light, note when shedding began, and record recent illness, medication changes, dieting or hairstyle changes. Use gentle handling and avoid tight pulling or high heat while you arrange an assessment. A dermatologist may examine the scalp and hair shafts, review your history and decide whether testing or treatment is appropriate. Finasteride treatment is one possible discussion for androgen-related loss, but it requires a clinician’s suitability review.

Seek prompt assessment for sudden patchy loss, painful or inflamed scalp, pus, heavy scale, broken hairs, eyebrow loss or rapid change. Earlier review can help when scarring or infection is a concern. Arrange routine care for gradual thinning so the pattern can be identified before choosing treatment.

Ask which pattern your examination suggests, whether a recent trigger could explain shedding, whether the scalp needs treatment, and what benefits, precautions and follow-up apply to any proposed medicine.
