Will this urine method work externally if you wash/rinse your hair in it? My hair has been thinning every since menopause and though I am not vain, it has affected my self-esteem quite a bit. All other efforts has been in vain. I dont want totake a perscribed drug because it would be lifelong and I dont like that at all. I wnet through menoapuse in my early forties and I am now in my early fifties.
