There are several types of hair loss: baldness or loss of hair ( alopecia), Loss of all scalp hair (alopecia totalis), Hair falling out in patches(alopecia areata), Another type of hair loss is localised and caused by scarring.

Alopecia most frequently occurs in men, but occasionally in women. A single hair generally last 2-6 years and is then replaced by a new hair. When baldness begins, there is an excess of shorter, thinner hair- the kinds babies have on heir head. Although, it is normal to lose as much as 100 hairs a day. Once the hair follicle dies, it never again produces hair. Yet there are instances in which the hair follicle has not died, but only has stopped producing hair. Careful treatment restores growth.

CAUSES OF BALDNESS AND HAIR LOSS
Heredity ( especially in men), hormonal factors, aging, local or systematic disease. Localised hair loss could also be caused by scarring following a wound or operation.
Other factors include poor circulation, high fever or other acute illness, surgery, radiation (X ray therapy), medicinal drugs, anesthesia, stress, poor diets, skin diseases, sudden weight loss, iron defficiency, thyroid diseases, obesity, birth control pills, diabetes, or vitamin deficiency,

Significant causes of hair baldness include the use of hair dyes. Washing it daily, or hot-air dryers. Hair pulled too tight in ponytails or braids, or set in tight rollers can sometimes come out as patches.

Hair loss in women most often occurs after menopause. Some women lose some hair 2-3 months after childbirth because hormonal changes during late term tend to block normal hair loss. But this is reversed within 6 months. Hypothyroidism can cause hair loss. Too little vitamin A can cause hair loss.
