Stop Hair Loss

Baldness is not usually caused by a disease, but is related to aging, heredity, and testosterone. In addition to the common male and female patterns from a combination of these factors, other possible causes of hair loss, especially if in an unusual pattern, include: Hormonal changes (for example, thyroid disease, childbirth, or use of the birth control pill)
A serious illness (like a tumor of the ovary or adrenal glands) or fever
Medication such as cancer chemotherapy
Excessive shampooing and blow-drying
Emotional or physical stress
Nervous habits such as continual hair pulling or scalp rubbing
Burns or radiation therapy
Alopecia areata -- bald patches that develop on the scalp, beard, and, possibly, eyebrows. Eyelashes may fall out as well. This is thought to be an immune disorder. Tinea capitis (ringworm of the scalp) 

Unfortunately many people are not aware of the fact that while hair can be extraordinarily resilient, once it has emerged from your scalp is has no facility for renewing itself. It is considered to be dead protein.

Think about it. Two years is a long time for hair to be subjected to the daily wear and tear of the environment, washing, drying, brushing, combing and any chemical processing. Just imagine what a piece of silk or fine fabric would look like after 2 years of constant handling.  

Diagnostic tests that may be performed (but are rarely needed) include: Microscopic examination of a plucked hair
Skin biopsy (if skin changes are present)
