Types of hair lossTuesday 11 November 2014
Androgenic Alopecia (AGA)
Androgenic Alopecia is a genetic form of hair loss and is common in both men and women. Men who suffer from this type of hair loss, also referred to as male pattern baldness, may experience the beginning of hair loss in their early twenties. This type of hair loss can be characterized as hair loss with a receding hairline and gradual loss of hair at the crown and front of the scalp (bald spots). Women with this condition, female pattern baldness, only experience thinning hair when they are at least 40 years old. Women suffer from thinning hair all over the scalp, mostly at the crown. This type of hair loss is often seen as something that can not be treated, but that is far from the truth. If you are on time, you can greatly limit the hair loss and even stimulate regrowth.
Telogen Effluvium is a type of hair loss that is temporary. It is caused by changes in the growth cycle of the hair. A large number of hais end up in a resting phase at the same time, causing a lot of hair to fall out. The hair becomes thinner, but bald spots do not really become visible. The hair loss can occur suddenly and be so severe that it becomes thinner in a short time, but it can also start slower and last longer.
Alopecia Areata (AA)
Alopecia Areata is a type of hair loss that is caused by an autoimmune disease. Alopecia Areata can be divided into different forms. First is Alopecia Totalis: in this type, one has lost all hairs on the scalp. Second is Alopecia Universalis: not only are there no more hairs left on the scalp, the eyebrows, eyelashes and all other hairs on the body are also gone. Two less common forms of Alopecia Areata are Alopecia Areata Monolocularis: baldness only occurs on one spot on the scalp; and Alopecia Areata Barbae: hair loss in spots of the beard of the man.
Involutional Alopecia and Senile Alopecia
Involutional Alopecia and Senile Alopecia can best be described as hair loss in old age. It is a natural condition in which the hair follicles remain in the resting phase (see our article on how hair grows). With age, less hair starts growing and it becomes thinner and shorter. The density of the hair on the scalp decreases.
Scarring Alopecia, also called cicatricial alopecia or scarred alopecia is not always visible on the basis of scars on the scalp. The scars are often located beneath the scalp, where hair follicles are replaced by scar tissue.
With Traction Alopecia, you will lose your hair gradually due to prolonged tension of the hair follicles. When you frequently wear your hair in a tight braid or pony tail, this can result in hair loss.
In men with a predisposition to baldness, the premature hair loss can start at an early age (around 15 or 16 years old).
Tinea Capitis is the name of the most common reason why children lose their hair: due to a fungal infection. This condition is very rare in adults. Depending on the severity of the infection, the child will suffer from dandruff, a red scalp or complete hair loss. In the case the infection is treated relatively early, all of the hair will grow back later.
