There are many types of hair loss, also called alopecia.
Both men and women tend to lose hair thickness and density as they age, this gradual thinning of hair is a natural condition known as involutional alopecia. It happens when more than normal amount of hair follicles go into the resting phase and growth phase is less.
Another genetically predisposed condition of baldness is androgenic alopecia commonly known as pattern baldness. It is a common form of hair loss in both men and women but the timing and pattern of baldness varies according to gender. Men with this condition can begin suffering from hair loss as early as in their teens, while women experience thinning of hair in their late 30’s. In men, this condition is commonly known as male pattern baldness and is characterized by receding hairline and thinning at the crown. In women, androgenetic alopecia is also known as female pattern baldness. Women with this condition experience thinning of hair all over the head but the hairline does not recede. Androgenic alopecia in women rarely leads to total baldness.
Spot baldness or alopecia areata in children and adults affect suddenly and is thought to be an autoimmune disorder where the body attacks its own hair follicles. In 90 percent of cases, the hair will grow back within a few years.
Another type is called “cicatricial alopecia” or the scarring alopecia which causes inflammation. The inflammation destroys the hair follicles replacing it with scar tissue and causing permanent hair loss.
Telogen effluvium is characterized by hair thinning and shedding over the scalp triggered due to physiologic stress or hormonal change causing a large number of your hair strands to enter telogen at one time. Hormonal changes in the post delivery period are a common cause of this kind of baldness, thus women are more prone to this kind of alopecia.
Trichotillomania is an impulse control disorder characterized by repeated urge of pulling out one’s own hair, seen mostly in children and is treatable.
