Testosterone replacement is becoming popular for men. Cotsarelis warns that this may accelerate hair loss. Propecia might help -- but because it prevents testosterone breakdown, it might affect the dose of male hormone replacement therapy. Cotsarelis warns men taking both Propecia and testosterone replacement to make sure their doctor carefully monitors their testosterone levels.
Low ferritin (the stored form of iron) is one of the most common causes of hair loss in women. Given low ferritin is also a common problem for hypothyroid people, it is important to have iron testing including ferritin especially if you are experiencing hair loss. It is not enough to be told by your doctor that your iron levels are ‘normal’. Ferritin levels are not always tested. Get a copy of your lab results and be sure ferritin has been specifically tested. Even if ferritin is within the ‘normal’ range that doesn’t make it ‘optimal’.
Less common causes of hair loss without inflammation or scarring include the pulling out of hair, certain medications including chemotherapy, HIV/AIDS, hypothyroidism, and malnutrition including iron deficiency. Causes of hair loss that occurs with scarring or inflammation include fungal infection, lupus erythematosus, radiation therapy, and sarcoidosis. Diagnosis of hair loss is partly based on the areas affected.
Both emotional and physical stress (such as a serious illness or recovery from surgery) have been associated with hair loss. It is possible that stress induces hormonal changes that are responsible for the hair loss, since hair loss is a known consequence of other hormonal changes due to pregnancy, thyroid disturbances, or even from taking oral contraceptives.
First, hair grows and gets longer in the anagen phase which can go on for several years. Then, during the ~10-day catagen phase, hair stops actively growing and separates from its follicle, which is what holds the hair in place beneath the skin. Finally, in the telogen phase, the follicle goes into rest mode for several months until the hair falls out. Then, the process starts anew.
When you're investing considerable time and money on a mix of hair treatments and cures, the last things you should be doing are those that will only aggravate your condition. Likewise, when your hair has finally grown back, the last thing you would want is for you to go through another horrific episode of hair loss. Preventing further - or another case of hair loss, and stopping it before it actually happens should be your goal.

Choosing where and who will perform your hair transplant is as important a consideration as to what kind of hair transplant to get. Of utmost consideration is that this should be done by the dermatologist /surgeon, and not his/her technician. The surgeon himself/herself should also oversee the design of your hairline and how the extraction of the graft will be done.
