Alopecia Symptoms- Causes, and
Treatments
|
|
Alopecia is loosely
defined as hair loss. There are many types of alopecia symptoms,
caused by many different factors. Hair loss can be genetic,
self-induced, partial, total, caused by drugs, diseases or medical
treatment, caused by parasites, or stress-related. While these are
only a few of the possible causes for hair loss, it's important to
know that only a medical doctor can diagnose the correct cause of
your condition and then recommend the necessary treatment. Before
you try any treatments on your own, see a physician. You'll save
time and money and will be on the right path to combating your hair
loss effectively. This article discusses some of the more common
forms of alopecia symptoms, along with causes and treatment. |
One of the many alopecia symptoms is
demonstrated by the condition alopecia areata. A bare patch appears on the
scalp about an inch across. Thought to be an autoimmune disease, the
body's immune system attacks the follicle. This causes the hair to stop
growing and enter a dormant phase. Eventually, the hair will fall out. To
regrow the hair, a mechanism must be found to keep the white blood cells
of the immune system from assaulting the follicle. There are 2 variants of
this condition: alopecia totalis (loss of all scalp hair) and alopecia
universalis (loss of all body hair). Topical treatments include
corticosteroids, dithranol, Retin-A, minoxidil and zinc. Medicinal
treatments include systemic cortisone and immunosuppresant drugs.
Androgenic alopecia, better known as male
pattern baldness, is the most common type of hair loss in men. Alopecia
symptoms for this condition include receding hairline and thinning hair at
the temples and crown. Caused by a combination of genetic and hormonal
factors, this type of alopecia is triggered by the hormone
dihydrotestosterone (DHT). If you carry the genetic predisposition for
overproduction of DHT, your body produces too much of an enzyme called 5
alpha reductase. This enzyme causes too much DHT to be produced. DHT
attacks the follicle, causing the hair shafts that emerge to be thinner
and thinner. Finally they become transparent and disappear altogether.
Treatments include DHT blockers or 5 alpha reductase blockers like
minoxidil and finesteride. Retin-A and zinc have also seen some success.
An effective herbal treatment is saw palmetto extract.
Anagen effluvium is another cause of
alopecia. Certain types of medical treatment, such as chemotherapy cause
anagen effluvium. This treatment depresses the immune system, so that
anticarcinogenic drugs can destroy the rapidly-growing cancer cells. This
systemic weakness extends to the hair follicles. Alopecia symptoms for
this type of hair loss are generally sudden and complete, with the hair
coming out in large clumps. This type of alopecia is temporary and many
people claim that when their hair regrows, it is thicker and healthier
than before. There have even been cases where straight hair grows back
curly and vice versa.
In telegen effluvium hair loss is causes
by a sudden stressful event or severe emotional stress.
Hair stops growing and the follicle becomes inactive or dormant. This
dormancy phase lasts about 3 months, after which the hair will fall out.
In most cases the alopecia symptoms are temporary but sometimes remains
until the underlying stress or emotional condition is identified and
treated.
Systemic illness is often responsible for
alopecia symptoms like thinning or sudden and complete hair loss. Diseases
like overactive thyroid, underactive thyroid, diabetes, lupus and anemia
often have hair loss as a secondary symptom. Again, the hair loss is
usually temporary, but the cause must undergo treatment for the hair to
regrow.
Alopecia symptoms are as varied and
complex as the underlying causes. Many men make the mistake of
self-treating and are disappointed when the treatment doesn't work. You
should discuss your hair loss with your doctor. Only he will be able to
order the correct tests and provide a specific diagnosis. Then you'll get
treatment tailored to your specific situation that is more likely to
succeed.
