Trauma & Chemo
occurs when sudden or severe stress causes an increase in the shedding of the hair. A stressful event can cause the hair follicles to prematurely stop growing and enter into a resting phase. The hair will then stay in the resting phase for about 3 months after which time a large amount of hair will be shed. In some cases the hair loss continues until the underlying cause is fixed.
Temporary Hair Loss
can be caused by: Child Birth, Pregnancy Termination, Starting or Stopping Birth Control Pills, Fad Diets and Pills, Severe Stress, etc.
It is quite common for some women to experience some hair loss approximately 3 months after childbirth. This hair loss is triggered by the sudden changes in hormone levels.
In some cases hair thinning may occur due to the male hormones present is some types of contraceptive pills, this type of hair loss is similar to pattern baldness or Androgenetic Alopecia.
The shock involved in a major operation can result in sudden hair loss. Also after micrograft and minigraft surgery where follicles are transplanted on the scalp Telogen Effluvium almost always occurs.
Due to the shock of surgery the hair follicles will fall out within about 3 months after which time new hairs will grow from the transplanted follicles.
Some prescribed drugs have been reported as causing hair loss in some individuals. Here is a list of some drugs that have been reported to have a side effect of hair loss:
Alloppurinol ( for the treatment of Gout)
Heparin ( blood thinner)
Coumarin (blood thinner)
Clofibrate (Cholesterol lowering drug)
Gemfibrozil (Cholesterol lowering drug)
If you suspect that prescription drugs that you are taking are causing hair loss you should discuss this with your doctor.
Some people experience Telogen Effluvium or sudden diffuse hair loss after a traumatic event such as the death of someone close, an accident, abuse or other severe traumas. These events may trigger hair follicles to enter the resting phase prematurely in which case an increase in the amount of hair shed will be noticed about 3 months after the event.
However in some cases where diffuse and sudden hair loss occurs the hair loss may continue until the underlying cause is treated. Types of sudden diffuse hair loss that continues until the cause is treated are as follows:
Thyroid Gland Malfunction, Diabetes, Anaemia, Systemic Lupus Erythematosis
Thyroid Gland Malfunction: Generally the first test a doctor or specialist is likely to carry out on a patient who is experiencing hair loss is a thyroid function test, as a thyroid problem may result in hair loss, Two types of thyroid problems can occur and either of these problems can result in hair loss. These conditions are Hypothyroidism and Hyperthyroidism
Hypothyroidism occurs when the thyroid gland produces too little thyroid hormone (thyroxin) to meet the bodies needs.
Hyperthyroidism – Overproduction of Thyroxin Hyperthyroidism occurs when the thyroid gland produces too much Thyroxin hormone to meet the bodies needs. People with other auto-immune disease are especially vunerable to hyperthyroidism. Hair loss may occur from either hypothyroidism or hyper thyroidism. In some cases hair loss is minimal, however some individuals experience severe hair loss. Fortunately hair loss is usually reversible with proper treatment. If you suspect that you have a problem with your thyroid function then you should visit your doctor.
Diabetes: Diabetes occurs when the body is unable to metabolise carbohydrates correctly. Untreated diabetes can result in hair loss.
Systemic Lupus Erythematosus: This condition is an auto-immune disease which causes inflammation of multiple organ systems. The main signs of the disease are fever skin eruptions on the face and neck area, hands and arms. About half of the people with lupus will have hair loss. Systemic Lupus Eerythematosus mainly effects women between the ages of 20 and 50. It is thought that genetic makeup plays a major role in the development of the disease.
