Childbirth, trauma, illness, grief, changes in hormones, medication or extreme diet changes are a few factors that cause severe stress on the body. Such factors are common stimulants of the condition, telogen effluvium, a process that causes excessive shedding of hair as the cycle remains in the final resting stage.
Drastic changes to diet, such as weight loss programmes, can starve the hair follicle of the necessary nutrients needed for optimal function.
Many different types of trauma can cause the body to feel emotionally stressed. Significant life events that may qualify as major emotional stress include; loss of a loved one, heartbreak, parenting issues, work-related problems, PTSD and anxiety. As the body learns to combat these issues, it can force the hair follicles to remain in the resting phase and with regards to, telogen effluvium; result in imbalanced shedding.
If you feel that such factors are the cause of your hair loss, please consult your GP, who may refer you to a therapist or counsellor to treat the underlying cause. Those with significant, emotional stress-related hair loss, often recover with new hair growth once they feel better.
