What is Telogen Effluvium?

Telogen effluvium is a temporary hair loss condition that can affect women. It is the second most common type of hair loss diagnosed.  Telogen effluvium looks very similar to female pattern hair loss in that they both have diffused hair thinning throughout the scalp area.  Although the hair starts falling out, the hair follicles remain intact and can start producing hair again resulting in hair regrowth.

To understand telogen effluvium, you first need to understand the 3 main hair cycles.

The Anagen phase

The Anagen phase is the growth phase. About 90% of your hairs are in this stage.  The cells in the hair bulb divide rapidly creating new hair growth. Hair actively grows from the roots for an average of 2-7 years before hair follicles becomes dormant. In this time, hair can grow anywhere between 18-30 inches.

The Catagen phase

Catagen is the transitional phase between Anagen and Telogen. This period is short, lasting only 2-3 weeks on average. In this transitional phase, hair stops growing and detaches itself from the blood supply and is then named a club hair.

The Telogen phase

The final phase or resting phase is called the Telogen phase. This phase begins with a resting period, where club hairs rest in the root while new hair begins to grow beneath it. This phase lasts for around 3 months.


What happens in telogen effluvium is a change in the number of hair follicles that are in the anagen phase that, triggered by a trauma to your body, changes quickly to the telogen phase creating more dormant hair follicles. This results in hair thinning and diffused hair loss.

Telogen effluvium can be triggered by many traumatic things to your body such as a poor diet (lacking certain vitamins or minerals), sudden weight loss due to dieting, surgery, certain drugs, extreme stress, metal toxicity, pregnancy, menopause, and other underlying health conditions.  So, it is important for a Trichologist to ask you questions about these issues to determine what other things could be contributing to your hair loss.  Telogen effluvium is a temporary hair loss condition and once the underlying issue is resolved, your hair should start growing back in three to six months.

Triggers causing Telogen Effluvium

  • Hormonal changes – childbirth, menopause
  • Physical trauma
  • Emotional stress
  • Poor nutrition
  • Birth control pills
  • Medication
  • Radiation therapy
  • Illnesses, such as diabetes and lupus
  • Significant weight loss

The hair loss in telogen effluvium usually starts after 3 months of the triggering event and can last about 6 months, in more extreme cases lasting up to a year.  Therefore, if you are just starting to notice your hair loss, you may want to look back at the events 3 months ago that may have triggered telogen effluvium.

Telogen effluvium hair follicles remain intact. The long telogen hair is replaced by shorter anagen hair that starts to grow from the follicle. Once the new anagen hair starts to grow in 3 to 6 months, the hair loss caused by telogen effluvium is resolved.

Characteristics of Telogen Effluvium

  • Normal looking scalp
  • Diffused hair loss all over the scalp
  • Temporary hair loss
  • Losing hair has white bulb and lack of shiny sheath
  • Dry looking hair that are sparse and easily pluckable
  • Hair colour changes from dark to brown, or red, brown to blond

Nonmedical Treatments for Telogen Effluviuim

At the TRICHOLOGY CENTRE, more natural treatments for telogen effluvium is preferred over prescribed drugs as many of them have negative side effects.  We have proven hair loss treatments and nutritional counselling that can stabilizes and help with the regrowth of your hair.


The role of diet and nutrition to help telogen effluvium is growing. New evidenced-based recommendations that micronutrients including certain vitamins and minerals have shown positive results. Micronutrients can reduce oxidative stress, an increasingly suspected contributor to telogen effluvium. Vitamin D for example, have shown to help modify the immune response by inhibiting Th1 cell proliferation.

Vitamin D – Vitamin D boosts immunity, keeps bones strong and skin healthy, stimulates cell growth, and helps create new hair follicles. Vitamin D deficiency has been linked to telogen effluvium.

Iron or ferritin – Iron deficiency remains the most common nutritional deficiency in the world, a sign of which includes chronic diffuse telogen hair loss.

Vitamin A or retinoid or retinol – Vitamin A is an essential vitamin for hair follicles. It also helps skin glands make sebum. Sebum moisturizes the scalp and helps keep hair healthy.

Biotin – Biotin is an important coenzyme for carboxylation reactions. Biotin deficiency has been shown to cause hair loss.

Vitamin E – Like vitamin C, vitamin E is an antioxidant that can prevent oxidative stress. In one documented study, people with hair loss experienced a 34.5% increase in hair growth after supplementing with vitamin E for 8 months.

Magnesium – Magnesium acts as a cofactor for over 300 enzyme systems, and plays an important role in nucleotide synthesis, a frequent process in the rapidly dividing hair follicle.

Zinc – Zinc is an essential mineral upon which hundreds of enzymes depend for their catalytic activity

Vitamin C – Vitamin C is a powerful antioxidant that helps protect against the oxidative stress caused by free radicals. It also helps your body absorb iron, a mineral necessary for hair growth.

Selenium – Selenium also contributes to antioxidant defense mechanisms via its interaction with the enzyme glutathione peroxidase.

Vitamin B12 or cobalamin – B12 contribute to nucleic acid production and thus possess an important role in the health of the hair follicles.

Folic acid or folate – Folic acid is primarily responsible for healthy cell growth including the cells in hair follicles.

Copper – copper acts with zinc in the antioxidant enzyme copper/zinc superoxide dismutase.


Adding certain vitamins and minerals can help promote hair growth and nurture the hair follicles and scalp.  Speak with a certified Trichologist on the best dietary, vitamins and minerals to help you with telogen effluvium.
