What Is Anagen Effluvium? Symptoms, Causes And 2 Ways To Treat

Anagen Effluvium :

Hair loss occurs within days or weeks of the injury to the follicle and the hair shafts are broken rather than shed. An AE can involve up to 90% of the hair on the head, it has the potential to cause almost complete alopecia.

Telogen Effluvium :

The hairs that are shed have a characteristic club shape with unpigmented proximal ends. Hair loss occurs 3 to 4 months after the systemic insult. It rarely involves more than 50% of the hair on the head.


When Anagen Effluvium occurs it is the direct result of some traumatic occurrence in the body. The issue revolves around the division of cells as they relate to the growth of hair and the ways in which the hair will grow over time.

  • Cancer Chemotherapy & Radiation Therapy - Most Common Causes
    Chemotherapy destroys cells. It works best against fast-growing cells such as cancer cells. However, there are other cells like hair follicle cells, that multiply just as quickly. Unfortunately, the chemotherapy drugs may not be able to discern the two, the drugs also attack the hair roots. The difference is that the normal cell will repair themselve, making the side effect temporary.

  • Nutrient Deficiencies Extreme deficiency of Copper, Iron, Zinc, Biotin, Essential Fatty Acids, or Vitamin C in the diet.
  • Vitamin A Poisoning Doses between 5,000 to 35,000 are beneficial to hair growth. An overdose can inflame the hair follicles.
  • Hypothyroidism, Hyperthyroidism It can force hair follicles to remain in the dormant phase for a longer period of time.
  • Genetic Hereditary Disease Such as Pollitt's Syndrome, Marie Unna Type Hypotrichosis
  • Hypopituitarism (Hypopituitary Dwarfism, Simmond's Disease, Sheehan's Syndrome)
  • Oral Contraceptives


Locating The Source Of The Trigger - Best Way

If the reasons of AE such as chemotherapeutic or radiation are discontinued, regrowth of hair can be expected within weeks spontaneously, hair that grows back may show a change in the texture and color. These changes may persist for years.

Rogaine - The Second Way

Rogaine has been shown to shorten the duration of hair loss due to chemotherapy and/or radiation by approximately 50 days, but it is unable to prevent hair fall due to cancer chemotherapy or radiation therapy.
