Types of Hair Loss

Most of the hairs on the scalp remain in the growth phase. There are about 100,000 hairs on the scalp and we lose few or more hair every day. The problem starts when we start losing large number of hair every day. Let us understand different types of hair loss and their pattern.

The different types of hair loss are telogen effluvium, traction alopecia and alopecia areata. Each of these follow a different pattern of hair loss and a certain phase of hair growth pattern is associated with each of them. Hence, let us understand the various phases of hair growth.

The first is the anagen phase of the growth phase. Then is the catagen phase which is also known as the intermediate phase. The last phase is the telogen phase or the resting phase of the hair. The hair are lost after the telogen phase. Hence, it is quite normal to lose hair every day. It is only when you start losing more than 300 to 700 hairs everyday that you must seek medical help.

Telogen effluvium

This type of hair loss occurs due to interruption in the normal growth cycle of the hairs. Significant amounts of hair suddenly enter the telogen phase which leads to loss of hair in large quantities. It is a temporary type of hair loss and usually is seen after the pregnancy.

It may also be due to a major emotional or physical shock.

This is not a very serious type of hair loss. Usually, there is no treatment required and the hairs regain their natural growth pattern once the follicles become active again.

Traction alopecia

This type of hair loss occurs due to excess stress put on the hair follicles because of tight buns, extreme hair styles such as ponytails and braiding close to the roots. This causes the hair to fall out due to damaged roots.

Those who allow their hair to be open and the follicles to recover may observe traction alopecia as only a temporary problem.

Alopecia areata

This is a serious type of hair loss and small round patches can be seen on the scalp as a result of hair loss. The exact cause is not known and dermatologists classify it under autoimmune disorders.
