Excessive or abnormal hair loss is known as alopecia, and there are several
kinds. What all hair loss has in common, whether it's in men or women, is a
symptom of something that's gone wrong in your body. Your hair will remain on
your head where it belongs unless hormone imbalance, disease, or some other
condition occurs. That condition may be as simple as having a gene that makes
you susceptible to male or female pattern baldness or one of the forms of
alopecia areata, or it may be as complex as a whole host of diseases.
Fortunately, hair loss can be a symptom of a short-term event such as
stress, pregnancy, disease, or medication, which can all alter hair's growth
and shedding phases. In these situations, hair will grow back when the event
has passed. Once the cause of the loss is addressed, hairs go back to their
random pattern of growth and shedding, and your problem stops.
People lose hair for various reasons. Illness and medication (like chemotherapy to treat cancer) can cause hair loss. Hair loss can also be inherited from a parent. Often, hair thins because it is fine-textured -- or because too many harsh chemicals have been used on it -- so it breaks easily.
These are hair care tips to help protect hair, prevent further hair loss, and add volume to your existing hair.
What Your Hair Says About Your Health
The first two types of hair loss in women are associated with
dihydrotestosterone (DHT), a derivative of the male hormone, testosterone.
The majority of women with androgenetic - also called androgenic - alopecia
have diffuse thinning on all areas of the scalp. (Men rarely have diffuse
thinning but instead have more distinct patterns of baldness.) Some women have
a combination of two pattern types.
Androgenic alopecia in women is due to the action of androgens, male
hormones that are typically present in only small amounts. Androgenic alopecia
can be caused by a variety of factors tied to the actions of hormones,
including some ovarian cysts, taking high androgen index birth control pills,
pregnancy, and menopause.
Just as in men, the
hormone DHT appears to be at least partially to blame for the
miniaturization of hair follicles in women suffering with female pattern
baldness. Heredity plays a major factor in the disease.
When your body goes through something traumatic like child birth,
malnutrition, a severe infection, major surgery, or extreme stress, it can
impact your hair. Many of the 90% or so of hairs in the growing (anagen) or
transitional (catagen) phases can actually shift all at once into the resting
