When I see ads for quick weight loss diets I'm reminded of the serious damage they impose upon unsuspecting hair follicles.
Juice fasts and other popular quick reduction diets may help shrink people into skinny jeans overnight. They can also cause luscious hair to shrink along with the fat.
Unfortunately, many people are unaware of the dangers of quick weight loss and the stress which occurs to their strands.
Sudden Hair Loss & Strict Diets
It's a proven scientific fact that a diet which weighs in at less than 1,200 calories a day can trigger sudden diffuse hair loss known as Telogen effluvium.
Note: Telogen effluvium (TE) is not the same as Anagen effluvium (AE) with is sudden hair loss from chemotherapy or radiation treatments.
The body often reacts to the physical stress of severely reduced calories or necessary nutrients by falling out in clumps. Diets which are especially low in protein are most suspect.
When the body is deprived of sufficient protein, through dieting or other abnormal food consumption, it will become malnourished.
The Body Reacts To Threats Of Survival
The human body is an amazing machine. If the threat of survival is present, the body will shut down all production of hair.
The body saves protein by shifting healthy hairs which are in a normal growth phase (anagen) into a sudden resting phase.
Under healthy conditions about 85-90 percent of all hair is in the growing phase.
Hair Is Forced Into A Sudden Resting Phase
Telogen effluvium does not usually cause bald patches but it does prematurely force a much larger percentage of scalp hair into a sudden resting phase.
Hair that is forced into an early resting period will almost always react by thinning and falling out.
Teloptosis Is Termination Of Telogen Phase
Teloptosis is the termination of the telogen phase with hair shedding. The initiation of the next anagen phase is independent from teloptosis.
Both events are triggered by distinct factors. Teloptosis is the result of the loss of adhesion between cells of the club hair and those of its epithelial envelope.
Those with an epithelial sheath indicate strong binding, suggesting early telogen, whereas the absence of an epithelial sheath indicates loose binding, conveying teloptosis.
Hair Loss Cycles During Crash Dieting
Massive hair shedding may not happen immediately after a new fast or similar crash diet is started.
In some cases there is a two to three month delay between the actual start of the diet and the actual beginning of hair loss.
Sometimes a person will have stopped crash dieting only to experience the sudden hair loss months later.
This can cause confusion regarding the cause of the sudden hair loss.
If you crash diet for two months then experience Telogen effluvium hair loss, your hair may not stop falling out until several weeks after you discontinue dieting.
The re-growth cycle for hair lost to TE can last anywhere from 6 to 12 months after the Telogen effluvium related hair loss subsides.
This means the total hair loss and re-growth cycle can last 6 months, or possibly longer, when induced by physical stress of calorie deprivation.
The physical stress of extreme weight loss may increase the production of androgens, the male sex hormones that are destined to kill hair follicles.
One the androgen production is increased and the hair follicles are destroyed no re-growth will occur. Although most people will experience total hair re-growth, some people won't be so fortunate.
Limited caloric diets and large weight fluctuations may trigger more permanent genetic hair loss conditions to appear earlier than normal.
Prolonged crash dieting by people who are genetically predetermined towards hair loss can result in hair that is lost forever.
Dermatologists & Tests For TE
A good dermatologist or other hair loss specialist can make a proper diagnosis to determine what type of hair loss you have.
Although some people assume that their sudden hair loss is TE, it might be some other hair loss condition that was coincidentally triggered because of a TE type of situation.
Some women after childbirth or during menopause will also experience TE.
This is a temporary form of hair loss that is triggered by hormonal changes, but also by crash diets (loss of over two pounds a week) or prolonged emotional stress.
It it's determined that you have pattern hair loss, though, this is more difficult to treat. Rogaine may help this form of hair loss, but it may not.
Some hair loss physicians will recommend a thyroid and iron (serum ferritin) test to determine your current hair loss condition and possible cause.
Other hair loss experts will be able to make a complete diagnosis with a complete history and simple examination.
Laboratory testing may not be necessary is some cases since there are actually just a few common causes of hair loss which can be related to most cases by a true hair loss expert. Scalp biopsies are rarely necessary except in extreme cases.
Be prepared for your appointment.
Read what you can about your suspected condition and take a notebook with your concerns and questions listed.
Ask questions about what may have caused the condition and ask how you can best treat your loss. As a rule doctors usually give you more attention if they feel you are knowledgeable.
Women Are At Most Risk
Although both women and men are susceptible to Telogen effluvium, dermatologists and other hair specialists report that women have a higher risk of experiencing the condition from prolonged crash dieting.
Some prescription drugs used in weight loss programs may also cause temporary hair shedding in some users.
Many of the Vitamin A related drugs may impact hair loss when applied topically.
Some of the more popular antidepressant drugs are also suspected of to causing TE related hair loss.
Other drugs suspected of causing hair loss include some blood thinners like Comarin or Heprin as well as some of the cholesterol drugs such as Clofibrate.
Other Possible TE Triggers
Besides crash dieting, women will often experience Telogen effluvium immediately after giving birth, during times of chronic emotional or physical stress, and from hormonal swings.
TE hair loss has also been reported by women approximately 3-4 months after terminating a pregnancy.
Studies have shown that women taking oral contraceptives for many years have some risk of developing the sudden hair loss condition.
Other causes of TE may include:
People suffering from eating disorders such as bulimia and anorexia are also prone to experience sudden hair loss at some point during the disease.
Permanent Or Temporary Hair Loss?
Although there are various professional opinions about TE and its ultimate impact, dermatologist and other hair experts generally agree that for the majority of people who experience TE, the hair loss is not permanent.
Hair loss can be categorized as hair shaft abnormalities, permanent alopecia, or nonpermanent alopecia. Nonpermanent alopecia, the most common type, includes androgenetic alopecia, telogen effluvium, alopecia areata and traction alopecia.
Hair Loss Will Likely Stop After The Condition Is Resolved
In general Telogen effluvium will stop approximately four to fourteen weeks after the cause of the condition is resolved.
There are exceptions to every rule and some people have reported TE related loss and re-growth lasting for up to one year. Other TE victims have even experienced chronic Telogen effluvium (CTE).
In the case of chronic TE the hair re-growth may be interrupted by more periods of sudden shedding.
There have been cases reported where TE was triggered, went into remission and continued to start again over a multiple year period. Everyone is different and will experience TE in their own unique way.
Although telogen effluvium, the most common type of diffuse hair loss in both women and men is usually self-limiting. In some rare cases the condition may become chronic if the trigger is not identified and corrected.
Some dermatologists that specialize in hair loss may prescribe Spironolactone (brand name Aldactone) or "Spiro" to help with Telogen effluvium conditions.
Spiro is an anti-androgen which blocks the androgens from the hair follicle. There have been reports of interrupted TE related hair loss as a result of taking Spironolactone
Ironically Spironolactone is not FDA approved for hair loss and is approved as an prescribed aide to lower blood pressure.
Some patients discovered that the drug will actually stop the TE shedding and will help to speed hair growth. Even more encouraging is the fact that Spiro does not seem to cause hair loss when the drug is discontinued.
Not everyone can handle Spiro and some will experience a worsening of their hair loss condition.
No one should ever consider taking Spironolactone without the specific advice of their dermatologist of physician.
Head For The Rogaine
The Dermatology Association of America officially recommends that "rogaine 5% (the Upjohn brand of minoxidil) should be used in cases of chronic telogen effluvium".
Not everyone agrees with this recommendation for a number of reasons. Some hair loss specialists have concerns about a 5% formulation of rogaine.
The concern is that the 5% formula may cause ultimate long term systemic problems for the body. Some experts are concerned because there has not been enough long term history to really know what happens when a high dose of rogaine is used for more than short periods of time.
Do you have to take rogaine forever once you start?
There is a lot of disagreement about this topic but many experts believe that using rogaine for 6-12 months will help to resolve chronic TE and allow normal hair growth resumption.
The manufacturer of rogaine disagrees. In some literature Upjohn suggests that rogaine must be taken for life once the treatment is started. While this may be true for some hair loss conditions, this not seem to be the case for most people with TE.
There are other known problems with Rogaine. Some people report that it can cause anything from mild to extreme itchiness.
It can also be messy, causing adjacent sections of hair to appear greasy and/or oily.
Prevention Is The Best Medicine
Practice prevention whenever possible.
Nutritional supplements and vitamins usually can't prevent or stop hair loss linked to rapid and massive weight loss.
Alternative Treatment Options
Although many people suffering from TE will work with a dermatologist or other licensed hair loss professional to halt the hair loss, others have found some measure of success with alternative treatments.
Consider using alternative healing treatments such as aromatherapy, acupuncture and acupressure. They have been proven to work successfully for some people. Herbal formulas and essential oil massage treatments enjoy a measure of success.
While many of the treatments will work for a large majority of TE sufferers, not all treatments will necessarily work for everyone.
Do your homework before you select alternative treatment methods and talk to others with similar TE hair loss issues to get their experiences.
Prevent Telogen effluvium by consuming the proper amount of protein and calories during a reduction diet.
Love your hair and avoid diets which triggers weight loss of more than 2 pounds per week. If lose too much weight overnight, you may have to buy a new wig to wear with your skinny new jeans.
