									ALOPECIA
         WHAT IS ALOPECIA?

   IT IS ABSENCE OR LOSS OF HAIR
         FORMS OF ALOPECIA
   AREATA-BALD SPOTS PATCHY HAIR LOSS

   TOTALIS-COMPLETELY BALD OR WITH
    LITTLE VISIBLE HAIR ON SCALP

   UNIVERSALIS-NO VISIBLE HAIR ON BODY

   CICATRICIAL-SCARRING HAIR LOSS
                 ALOPECIA AREATA
Current evidence suggests that alopecia areata is caused by an abnormality
in the immune system. This particular abnormality leads to autoimmunity.
As a result, the immune system attacks particular tissues of the body. In
alopecia areata, for unknown reasons, the body's own immune system
attacks the hair follicles and disrupts normal hair formation. Biopsies of
affected skin show immune cells inside of the hair follicles where they are
not normally present. What causes this is unknown. Alopecia areata is
sometimes associated with other autoimmune conditions such as allergic
disorders, thyroid disease, vitiligo, lupus, rheumatoid arthritis, and
ulcerative colitis. Sometimes, alopecia areata occurs within family
members, suggesting a role of genes and heredity.
ALOPECIA AREATA
     Is alopecia areata hereditary?
   Yes, heredity plays a role. In one out of
    five persons with alopecia areata,
    someone else in the family also has it.
    Those who develop alopecia areata for the
    first time after the age of thirty years have
    less likelihood that another family member
    will have it. Those who develop their first
    patch of alopecia areata before the age of
    thirty have a higher possibility that other
    family members will also have it.
           ALOPECIA TOTALIS
   Alopecia totalis is the loss of all head
    hair. Its causes are unclear, but it is an
    autoimmune disorder. Stress is sometimes
    thought to be a contributor to the hair loss
    caused by alopecia, however many people
    leading relatively stress-free lives have
    experienced the symptoms.
    ALOPECIA TOTALIS (CONT’D)
   In alopecia totalis, immune system cells
    called white blood cells attack the rapidly
    growing cells in the hair follicles that make
    the hair. The affected hair follicles become
    small and drastically slow down hair
    production. Fortunately, the stem cells
    that continually supply the follicle with
    new cells do not seem to be targeted. So
    the follicle always has the potential to
    regrow hair.
    IS THERE A DIFFERENCE BETWEEN
         AREATA AND TOTALIS?
   For all practical purposes, a few patches of hair loss is
    called Alopecia areata; while total hair loss all over the
    head, including eyebrows, eyes lashes is called Alopecia
    totalis.
   The treatment approach is different and the prognosis is
    also difference. That is, Alopecia Areata is treatable with
    great success, while Alopecia totalis is not curable using
    homeopathy. Steroids may help but superficially. Our
    experience suggests that by use of steroids, most
    patients get more spots elsewhere on the skin. Steroids
    do not address internal autoimmune disorder. But, they
    are very useful during acute attacks.
        ALOPECIA UNIVERSALIS
   The most advanced form in a series of
    conditions all related to the same disease,
    Alopecia Universalis is characterized by
    total a loss of body hair. A member of the
    group of hair loss conditions called
    Alopecia Areata, the only difference
    between Alopecia Universalis and it's
    variants is the extent of hair loss.
ALOPECIA UNIVERSASLIS (CONT’D)
   Patients are usually otherwise healthy, but have more
    thyroid disease and vitiligo than the general population.
    Those with vitiligo (patchy loss of skin color) may also
    develop AU in time. Many individuals with Alopecia
    Universalis are born with some hair, but then begin
    losing it very quickly. The disorder is inherited as an
    autosomal recessive trait. It is caused by a mutation in a
    gene dubbed HR in chromosome band 8p21.2 that is the
    human homologue of the mouse "hairless" gene -- the
    human version of the gene in the mouse that is
    responsible for hairless mice.
    ALOPECIA UNIVERSALIS (CONT’D)
   Is the "hairless" gene only found in people
    with Alopecia Universalis? Most likely.
    Based on the known research, we can
    safely assume that only individuals with
    this rare and severe form of Alopecia
    Areata carry the gene. Unfortunately,
    there have not been enough studies done
    to verify that this is true of all those
    afflicted.
    ALOPECIA UNIVERSALIS (CONT”D)
   Aside from genetic tendencies, the contributing causes of Alopecia
    Universalis are not known. It is important that those with it are
    careful to protect themselves from the sun, bacteria, and other
    potentially harmful elements, as the scalp, nasal cavity and eyes are
    not protected.
    According to the National Alopecia Areata Foundation, other than
    the hair, nails can also be affected. The nail involvement may be
    limited to pinprick indentations, all the way to severe distortion of
    the entire nail. Alopecia Universalis may be acute and short-lived, or
    remain permanently. The possibility of regrowth does remain
    however, even for those with 100% hair loss for many years.
    Predicting when regrowth may occur is not currently possible.
         ALOPECIA IN CHILDREN
   Hair loss in children is actually not very common,
    however it is significant enough that nearly 2 Million
    children suffer from at least one form of Alopecia (hair
    loss) or another in the United States alone. The good
    news is that at least 60% of children with Alopecia will
    "outgrow" the condition without need for treatment. As
    with all forms of Alopecia, a reversal and complete
    restoration of hair takes time - sometimes up to a year
    or more, but for the vast majority of children, it will
    spontaneously resolve. The bad news is that 40% wont
    have such luck, which can be quite frustrating both for
    the parents and the child affected by this often
    cosmetically embarrassing condition.
       CHILDREN WITH ALOPECIA
   Please keep in mind: hair loss in children is not due to vitamin
    deficiencies (unless extreme malnutrition is present), poor scalp
    circulation, headbands, hats, or cold weather. Diagnosis is typically
    as simple as an evaluation of the risk factors a visual examination of
    the type of loss, and some tests your doctor can perform.

   Alopecia is not life-threatening, and children who have it are
    otherwise healthy. Why the hair falls out from the roots is still a
    mystery. What is known is that the condition is not contagious,
    caused by foods, or the result of nervousness, hyperactive
    disorders, or psychological stress. In 20% of cases another family
    member has been affected. Some patients with this condition will
    also develop a grid-like pitting of the nails.
          CICATRICIAL ALOPECIA
   The cause of the various cicatricial alopecias is
    poorly understood. However, all cicatricial
    alopecias involve inflammation directed at the
    hair follicle, usually the upper part of the follicle
    where the stem cells and sebaceous gland (oil
    gland) are located. If the stem cells are
    destroyed, and the sebaceous gland as well,
    there is then no possibility for regeneration of
    the hair follicle and permanent hair loss results.
