Hair Loss Types and Causes

Hair loss is indeed very annoying, and in some conditions it tends to be worrying. Although this is normal, in some cases extra treatment is needed to prevent the condition of hair loss from becoming worse.

Causes of Hair Loss

Hair grows in almost all parts of human skin. Except for the palms and soles, there are many hairs that are so fine they are almost invisible.

Hair is composed of proteins (called keratin), which are produced in hair follicles in the outer layer of the skin. When the follicle produces new hair cells, old cells are pushed out through the skin surface at a speed of about six inches a year.

The hair that you can see is actually a series of dead keratin cells. The average adult's head has about 100,000 to 150,000 hairs and loses up to 100 strands a day; so if you feel that hair loss has not crossed the normal range, there is no need to worry too much.

3 Phase Hair Loss

At one time, about 90 percent of hair on a person's scalp grew. Each follicle has its own life cycle which can be influenced by age, disease, and various other factors. This life cycle is divided into three phases, namely anagen, catagen, and telogen.

Anagen:
active hair growth that lasts between two to six years

Catagen:
Transitional hair growth that lasts two to three weeks

Telogen:
a resting phase that lasts about two to three months; at the end of the resting phase, hair is released and new hair replaces it and the growth cycle begins again.

6 Types of Hair Loss

There are many types of hair loss, also called alopecia, which are:

Involutional alopecia:

a natural condition that occurs when the peat gradually wears away with age. More hair follicles enter the resting phase, and the rest of the hair is shortened and fewer in number.

Androgenic alopecia:

namely genetic conditions that can affect men and women. Men with this condition, called male pattern baldness, can start experiencing hair loss from their teens or early 20s. Women with this condition, called the pattern of baldness in women, do not experience noticeable thinning until the age of 40 years or more. Women experience general thinning throughout the scalp, with the most extensive hair loss on the crown.

Alopecia areata:

often starts suddenly and causes hair loss evenly in children and young adults. This condition can cause total baldness (alopecia totalis). However, around 90 percent of people with this condition, still experience hair growth back in a few years.

Alopecia universalis:

which causes all body hair to fall out, including eyebrows, eyelashes, and pubic hair.

Trichotillomania:

which is most often seen in children. This is a psychological disorder in someone who has a tendency to pull his own hair.

Telogen Effluvium:

namely temporary hair thinning on the scalp due to changes in the hair growth cycle. Large amounts of hair enter the resting phase at the same time, causing hair loss and subsequent thinning.

In addition, thin hair and loss, can indicate the condition of malnutrition in toddlers aged up to two years. Toddlers with this marasmus condition in addition to having thin hair that easily falls out, have a low weight, are prone to infectious diseases and have dry skin.

If you or your child experience an alarming hair loss, you should immediately consult a doctor.
