Alopecia is a condition affecting human beings where hair loss is prominent to the extent of being bald. It's one symptom to different diseases. But with me, I am having hair loss. Though not to the extent of losing a lot of hair. It's just overwhelming to see losing your hair when you comb it. Though there some hair loss shampoo in the market today, but I don't find them effective. It may be related to something I eat or an underlying disease. Whatever it is, I hope it's not life threatening and irreversible.
