Hair Loss Problems
Male pattern baldness is the
major cause of hair loss but there are a lot more hair problems as illustrated
below.
Alopecia
This is a general term for
baldness, of which there are a number of different varieties. Some types are
permanent while others are only temporary, albeit the time scale can vary
enormously.
Some people can have alopecia without it really affecting them at
all whereas other sufferers go through a great deal emotionally trying to cope
with it. Listed below are the main types of alopecia.
Alopecia Areata
This
is normally first noticed as a small bald patch on the scalp. Usually a number
of patches in an area of the scalp develop and eventually join up to form larger
patches. A patch can sometimes form overnight, so that the hairs that are shed
are found on the pillow in the morning.
This can be a very frightening
experience for someone when it happens for the first time. The skin in the patch
is usually pale and glossy, with no hairs present. The hairs around the patch
are usually short and of a frayed appearance that can easily be pulled out,
which is the last thing that should be done.
The cause of alopecia areata
is not fully understood by doctors. Some people have a family history that could
suggest a genetic link. However stress and shock have been blamed as reasons for
the problem, while very often there is just no explanation at all.
Often the hair regrows on its
own accord after about a month, while at other times the bald patch will clear
up completely only to move to another area of the scalp.
Medical advice should be
sought as worrying about the condition can actually make it worse. Whilst there
is no actual cure for the condition, just being reassured that you are not
suffering from some major disease, will help ease the distress this problem can
cause.
Alopecia Totalis
This is the complete loss of
scalp hair combined with the loss of eyebrows and eyelashes, as well as beard
hair in men.
Regrowth is rare once the condition is established, so medical help
should be sought as quickly as possible. However a cure is normally unlikely to
be found.
Alopecia Universalis
This is the total loss of all
body hair as well as all the scalp hair. Once this is established regrowth is
extremely unusual.
This condition could be caused by severe shock, or even an
accident such as falling out of a tree. Again medical advice should be sought as
soon as possible, although very little can be done to regrow the hair.
Androgenic Alopecia
The popular name for this
problem is male pattern baldness. This is the most common type of baldness and
most men will suffer from it, although the degrees of severity can vary from
trivial to very extreme.
It can start in the late teens, mid thirties or even at
old age. The hair line recedes and there is loss from the crown until the whole
vertex is void of hair. This may develop over a few years or it can span about
ten years. There is a reduction in the length of time the anagen stage lasts and
the hairs gradually become shorter and finer.
Eventually the hairs do not regrow, and the follicle closes. Hence baldness occurs.
Male pattern baldness has a
definite genetic link. Increasing age can also be an influencing factor. After
the menopause, androgenic alopecia develops in many women, this is often
disguised by having the hair permed. You see rather a lot of women around the
menopause age with permed hair which can help hide the problem that often clears
up after treatment.
There are just as many bald women as bald men in geriatric
wards of the hospitals.
Traction Alopecia
Traction alopecia is baldness
due to placing to much tension on the hair, causing it to loosen in the
follicle. If a pony tail is too tight there may be hair loss at the frontal hair
line. Tight plaiting can result in hair loss at the sides of the base of the
plait.
Attachment of hairpieces may cause hair loss at the point of attachment.
The hair should grow back once this bad practice is discontinued, but can be
permanent if the habit goes on too long.
Diffuse Alopecia
Diffuse
alopecia is a gradual loss of hair across the whole scalp without any itching or
scaling being present. It occurs in females for a variety of reasons.
Medical
help should be sought in all cases because some of them may be serious. Below
are some possible causes.
Telogen effluvium (moulting)
following child birth, high fever or severe emotional stress. Many scalp
follicles enter catagen simultaneously, causing thinning of the scalp hair.
There should be regrowth within a few months. During pregnancy many women have a
prolonged anagen period and as many as 95% of scalp hairs may be in anagen by
the time they give birth. This is 10% more than normal. Within three or four
months of giving birth this figure may drop back down as low as 70%. Regrowth
generally takes another three months.
Not all pregnant women lose their hair, so
anyone who is pregnant should not worry about it.
Under activity of the thyroid
or pituitary glands. This will decrease the rate at which the whole body uses
energy and may be due to a tumour or, more rarely, a lack of iodine in the diet.
Iron deficiency. You do not
have to be anemic. If you have increased hair loss monthly, it could be linked
to the menstrual cycle. Tiredness is often a symptom.
The side effects of drugs. Ask
your doctor if this is possible. Drugs which help to prevent cancer, are
anti-mitotic and therefore slow down cell division in healthy cells such as
hair.
Severe illness such as cancer,
kidney or liver failure.
Cicatricial Alopecia
This is baldness due to
scarring. The follicles are absent in scar tissue. The scarring may be due to
wounds, burns or infection. Boils can cause scar tissue as may be seen on the
necks of many men.
Great care must be taken by hairdressers with hair
straightening chemicals that are highly alkaline and can burn and damage the
skin. Nothing can be done once scarring has occurred.
Alopecia Senilis
Alopecia senilis is baldness
due to old age. In most people the metabolism slows down with increasing age,
and nutrients fail to reach the follicles.
A similar thing happens to the bones
in old age, where even although enough calcium is taken in the diet, the bones
lose it and become brittle. This occurs in the majority of old people. There is
usually a general thinning on the head for which nothing can be done.
Alopecia Adnata
Congenital baldness or
baldness at birth.
Alopecia Follicularis
Hair loss due to inflammation
of hair follicles.
Alopecia Neurotica
Baldness following a nervous
disorder or injury to the nervous system.
Trichotillomania
This form of hair loss is
caused by pulling out one's own hair, usually without realising it. In young
children it often occurs after the birth of a new child, to get the attention of
the parents.
If the child is right-handed the baldness will tend to be greater
on the right side of the head. It usually stops with the knowledge that one is
pulling out one's own hair, but nervous" twiddling" of hair carries on
throughout life in some individuals.
In older people, this habit can persist
throughout the rest of their life, even though large areas of baldness can
occur. In some cases psychiatric care may be required.
If you pluck a hair out of
your head you are not actually pulling it out by the roots. The little bulb at
the end is not the hair root. To pull your hair out by the roots would be
extremely painful and your scalp would be bleeding badly, and more than likely
you would pass out.
Mentally disturbed patients can often cause damage to
themselves by pulling out their own hair, but they often have greatly
exaggerated shows of strength.
