Telogen effluvium or NT is one of the most common types of hair loss. Although poorly defined with a little research done to understand this condition, it is known that Telogen effluvium when there is a change in the number of hair follicles that's going to grow hair. If the amount of hair follicles that produce hair is reduced drastically, for some reason, when the telogen phase of the cycle of hair growth, a significant increase in hair follicles dormant occurring in the results or telogen effluvium . The hairs that are shed because telogen effluvium often hair in the telogen phase, recognizable by the small bulb keratin in the hair root.
Effluvium, also known as defluvium, manifested through a thinning hair in some parts, or all, the scalp. The thinning hair may be more extensive in some parts of the scalp, more often than not, the top scalp experiences of most weight loss compared with the rear and sides of the scalp. The hair usually not diminish at all, except in cases of chronic telogen effluvium. The hair loss due to effluvium is reversible as hair follicles not suffer permanent damage.
The development of Telogen effluvium can be caused by the following:
- Environmental factors
Some factors in the environment may cause effluvium. Some incidents may occur that can cause hair follicles to enter the sleep state. This can increase the shedding of hair and make thinning hair. Effluvium caused by environmental factors can occur rapidly and can become noticeable at least a month after the incident. If the incident which caused the movement of hair follicles in the resting state ends immediately, hair follicles can return to the Anaga or growth phase and start producing new hair.
- Prolonged telogen state
Hair follicles can go into the rest or telogen state and instead of returning to the growing phase or Anaga, stay at the stage of sleep for a longer period of time. This eventually leads to the slow and continuous accumulation of hair follicles in the telogen phase and a smaller number of hair follicles in the Anaga phase. More remarkable, but slowly shedding of hair may occur if the effluvium is caused by this phenomenon.
- Shortened hair growth cycle
The hair follicles go into a general overview of the stages of hair growth cycle. When this happens, fine hair can be experienced as well as constant shedding of short hair and thin fibers.
The emergence of telogen effluvium can be attributed to causes such as changes in hormone levels, stress, dietary problems, certain drugs and medicines, as well as chronic diseases.
Effluvium can also occur as part of another disease such as androgenetic alopecia. Effluvium can also be a symptom of other conditions such as alopecia areata.
