What to do if I'm 27 years old female and losing hair, what to do?

Androgens, TE, ormed. Many things including hormonal (PCOS etc), meds like antidepressants, or Inderal, (propranolol) thyroid disease, poor eating like vegan with little iron may co-exist with male hormone hair loss and Telogen effluvium. An endocrinologisti familiar with alopecia should be seen.
