Hair Loss Options: What to Know

A clinician may ask when shedding began, whether it is diffuse or patchy, and whether illness, stress, weight change, medicines, hairstyles or family history preceded it. The scalp is checked for scale, redness, broken hairs and follicle openings. Blood tests or other tests may be considered when the history suggests a nutritional, hormonal or medical contributor.

Possible explanations include telogen effluvium after a body stressor, pattern hair loss, alopecia areata, traction alopecia or scalp ringworm. The right treatment for one cause may not help another.

Arrange an assessment if shedding is new, persistent or troubling. Bring a list of medicines and supplements, note recent health changes, and take clear photographs in similar lighting so progression is easier to discuss. Use gentle hair care while waiting: avoid tight pulling, harsh chemical processing and vigorous brushing.

Treatment may involve correcting an identified trigger, treating scalp disease, or using a clinician-recommended medicine. Finasteride treatment is not suitable for everyone; discuss pregnancy potential, other medicines and side effects before considering it. Cosmetic fibers, a shorter style or hair restoration may help appearance, but they do not identify the cause.

Seek prompt medical advice for rapidly expanding bare areas, painful or swollen scalp, pus, heavy scale, broken hairs, or loss of eyebrows and eyelashes. Arrange care sooner if hair loss follows a new medicine or occurs with fatigue, faintness, menstrual changes or unwanted facial hair. Sudden patchy loss deserves assessment even when the skin looks normal.

Which pattern do you see, and what findings support that impression? Do I need blood tests or a scalp examination? What result should I expect from each option, how long should I try it, and what side effects require a review?
