Will Hypothyroidism Cause Hair Loss
?
Will hypothyroidism
cause hair loss ? Well, one of the symptoms of hypothyroidism
(an under active thyroid) is hair loss. To some people, hair
loss (the medical term is alopecia) represents the worst
symptom of their thyroid problem - the thinning hair, large
amounts falling out in the shower or sink, often accompanied by
changes in the hair's texture, making it dry, coarse, or easily
tangled.
But there is no
consistent correlation between the degree and duration of
hypothyroidism and the severity of hair loss. Diffuse alopecia
may sometimes be the first or only sign of hypothyroidism. The
hair loss in such cases is diffused.
There are three common
types of hair loss. General shedding of hair is typically hair
lost throughout the head. In general shedding of hair, there
are no specific patches of hair loss or even baldness. The
usual case is noticing more hair in drains and in the shower,
or in hair brushes. Typically, with hypothyroidism prior to
treatment, this is the most common form of hair loss.
Occasionally, it (hair loss) may continue for some people even
after hypothyroidism treatment.
The second type of hair
loss is commonly associated with fungal infection or autoimmune
alopecia. Circular patches of hair loss develops, and in some
cases, there is complete loss of hair in these patches. These
type of alopecia should be evaluated by a dermatologist because
it is not particularly associated with thyroid
dysfunction.
The third type of
alopecia is male pattern hair loss - it happens mostly to men,
but women can get it too. Male pattern hair loss is
concentrated on the temples and top of the head. The cause of
this problem is due to an enzyme which converts the hormone
testosterone on the scalp to dihydrotestosterone. This causes
hair follicles to shrink and then they disappear. Ironically,
this conversion of testosterone to dihydrotestosterone seems to
speed up in some patients with treated
hypothyroidism.
Shedding 50 to 100 hairs
a day is considered normal. When a hair is shed, it is replaced
by a new hair from the same follicle located just beneath the
skin surface. Scalp hair grows about one-half inch a
month.
Research is currently
being carried out to determine whether the application of
triiodothyronine (T3) - which is the thyroid hormone most
likely to affect the hair follicles - can counteract hair loss.
T3 was given to soldiers during the second world war for the
healing of wounds.
To prevent hair loss due
to hypothyroidism, some doctors and pharmacists prescribe
taking Saw Palmetto as it is considered a thyroid tonic. If
hypothyroidism cause hair loss in you, do give zinc a try also
as it has the ability to boost thyroid function. It is said to
be especially beneficial for those who have brittle or thinning
hair as a result of hypothyroidism.
An important point to
remember if you ever wonder will hypothyroidism cause hair loss
is that it can cause more damage than mere hair loss. Studies
have found that if someone has it and they are pregnant, then
the chances of giving births to children with low IQs is
magnified by four folds. So get the disorder treated if you are
pregnant.
