Beauty Glossary H-K
Hair is a growth consisting of
dead skin cells that are filled with a protein called keratin. Hair
originates in the dermis, the skin layer just below the surface layer
(epidermis). Each hair is encased and nourished by a follicle buried
under the skin.
“Androgenetic alopecia” commonly referred to as male or female pattern baldness.
or absence of hair is a hereditary and unavoidable condition. Most hair
loss is genetically inherited, some hair loss can be cause by stress,
depression, a side effect of medication, a dietary, vitamin or mineral
deficiencies or hormonal imbalance or various skin and other disorders.
Hair loss affects men and women. Not all hair loss is inevitable,
however, nor is the decline entirely controlled by genes.
you're likely to lose hair faster if your hair follicles become
inflamed or if you get skin disorders that affect your scalp. Things you
put on your hair can clog up the follicles or even kill them in some
instances. Go for a pure, natural, organic shampoo.
those with sensitive hair or skin, hair loss prevention can start by
choosing the right hair care products. Depending on the structure of
your hair and hair follicles, certain shampoos and conditioners will
help you maintaining healthy hair. You can also keep your hair from
being damaged by wearing a hat when outside in the sun for long periods
or severe hair loss, is much more common in men than in women. Hair
loss can result from genetic factors, aging, local skin conditions,
dietary deficiency and systemic diseases that affect the body generally.
Some medications, such as those used to treat cancer, also cause hair
Male-pattern baldness is
the most common type of hair loss affecting men. It's rare in women and
children because it depends on the presence of male hormones
(Androgens), and levels of these hormones are high in males after
puberty. Hair loss is inherited. Hair loss usually begins on the sides,
near the front, or on the top of the head toward the back. Hair loss can
begin at any age, even in teenagers. Some people lose only some hair
and develop a bald spot in the back or a receding hairline; others,
especially people whose hair loss begins at a young age, may go
Variations in a gene related to
male sex hormones may be at the root of male-pattern baldness, the most
common form of hair loss. The culprit is the androgen receptor gene, and
it dwells on the X chromosome, which all men inherit from their
mothers. Other, yet-unidentified genes are likely involved in
male-pattern baldness, possibly including ones handed down by fathers.
New findings highlight the importance of mom's side of the family when
it comes to a man's hairline.
Female-pattern baldness is
less common than male-pattern baldness. Usually, this condition causes
the hair to thin in the front, on the sides, or on the crown. It rarely
progresses to total hair loss.
goes grey when melanocytes become depleted. The scalp contains a
reservoir of adult stem cells that provide a continuous supply of these
color-making cells. But as the body ages these cells become depleted and
sometimes begin to develop in the wrong part of the hair follicle.

Hormone replacement therapy (HRT)
replacement therapy (ERT) refers to the daily use of estrogen to
increase a woman's hormones to premenopausal levels. Women with a uterus
who take estrogen also need the hormone progestin to prevent the
estrogen from affecting the uterine lining (endometrium), which can lead
to endometrial cancer. The combination of estrogen and progestin is
called hormone replacement therapy (HRT). Women with a uterus take HRT.
Women who have had a hysterectomy to remove the uterus take ERT.
U.S. Food and Drug Administration (FDA) has updated its HRT
recommendations and now only approves estrogen-progestin HRT for:
Short-term treatment of perimenopausal symptoms. Women who do decide
that HRT benefits outweigh their risks are advised to use the lowest
effective dose for as short a time as possible, not exceeding 3 or 4
* Osteoporosis prevention and treatment, in select,
severe cases. Most experts recommend that HRT only be considered for
women with significant risk of osteoporosis that outweighs their risks
from taking HRT.
Women are now encouraged to consider all possible osteoporosis treatments and to compare their risks and benefits.
Hyaluronic acid (HA)
acid is a natural polysaccharide which is as one important structural
element in the skin and in subcutaneous and connective tissues.
Hyaluronic acid is also found in the synovial tissue and fluid.
Hyaluronic acid belongs to a group of very few subsances which are
identical in all living organisms.
As Hyaluronic acid is a natural
biotic component, widely existing in skin and any other tissue.
Hyaluronic acid has been used in high grade skincare for its high
plumping and moisturising effects. HA is called Natural Moisturing
Hydroxycitric acid (HCA)
acid (HCA) is a natural substance that is extracted from the rind of
the fruit of the Garcinia cambogia tree, and has been extensively
studied for over thirty years and found to be effective in inhibiting
lipogenesis, lowers the production of cholesterol & fatty acids,
increases the production of glycogen in the liver, suppresses appetite,
increases the body’s production of heat by activating the process of
thermogenesis, and encourages weight-loss in laboratory animals. This
acid is a natural compound that is similar to citric acid found in other
citrus fruits. A decoction of the fruit rind is often given in support
of rheumatism and bowel complaints. There have been numerous studies
lately that determined possible uses of HCA for dieters or athletes.
Research with animals has found that HCA enhances weight loss by curbing
the animal's appetites naturally, and by modifying their metabolism so
that they have less of a tendency to convert carbohydrates to fat. Other
studies have found that HCA supplementation may decrease appetite and
also inhibit the actions of a specific enzyme in the liver called ATP
Cytrate Lyase. This enzyme is specifically responsible for the
conversion of carbohydrates to fat.
Intrauterine device (IUD)
IUD is a long-term birth control method.
is a small, T-shaped plastic device that is wrapped in copper or
contains hormones (progesterone). IUD prevent fertilization of the egg
by damaging or killing sperm. A copper IUD may also be used as emergency
contraception. The hormonal IUD must be replaced every 5 years. The
copper IUD can remain in your body for as long as 10 years.
