Typical male pattern baldness involves a receding hairline and thinning around the crown with eventual bald spots. Ultimately, you may have only a horseshoe ring of hair around the sides. In addition to genes, male-pattern baldness seems to require the presence of the male hormone testosterone. Men who do not produce testosterone (because of genetic abnormalities or castration) do not develop this pattern of baldness.
For hair loss caused by illness (such as fever), radiation therapy, or medication use, no treatment is necessary. The hair will usually grow back when the illness has ended or the therapy is finished. A wig, hat, or other covering may be desired until the hair grows back.
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)
Some women also develop a particular pattern of hair loss due to genetics, age, and male hormones that tend to increase in women after menopause. The pattern is different from that of men. Female pattern baldness involves a thinning throughout the scalp while the frontal hairline generally remains intact.
For hair loss due to heredity, age, and hormones, the topical medication Rogaine (minoxidil) can be helpful for both male and female pattern baldness. Expect to wait 6 months before you see results. The oral medication Propecia (finasteride) is effective in some men. This medicine can decrease sex drive. When either medication is stopped, the former baldness pattern returns.
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.
