ALPHABETICAL
ORDER
- Alopecia
- This is a
medical term for hair loss or baldness in general. There
are different types of alopecia.
- Alopecia
androgenetica
- This is a
medical term for male pattern baldness or female pattern
baldness. This type of hair loss is usually hormone related.
-
Alopecia
areata
- It refers to
the condition when there are well defined oval shape bald
patches on the scalp.
- Alopecia
totalis
- It refers to
the condition when all the hair on the scalp is lost.
- Alopecia
universalis
- This is an
extreme case of baldness where all the hair on the scalp and
the entire body is lost.
- Amino acid
- Amino acids
are the building blocks of proteins and are the end products
of protein digestion. They are essential for human metabolism.
- There are
almost 100 kinds of amino acids. The main source of essential
amino acids is from food. Essential amino acids include:
methionine, cysteine, histidine, isoleucine, leucine, lysine,
tyrosine, threonine, valine, phenylalanine and tryptophan.
- Some proteins
contain all the essential amino acids, eg: milk, cheese, eggs
and meat.
- Once the
protein is broken down by means of digestion, amino acids pass
onto the bloodstream and is absorbed by the tissue depending
on the tissue's requirement for amino acids.
- Since protein
is the building block for healthy hair, lack of amino acids in
the body may adversely affect hair growth.
- Anagen
- It refers to
the growing phase of hair cycles.
- Anti-androgens
- Antiandrogens are sometimes referred to as androgen
antagonist. It represents a family or a class of hormone
antagonist compounds that are capable of preventing or inhibiting
the biologic effects of the male sex hormones (androgens) on
androgen-responsive or androgen-sensitive tissues in the body. The
word antiandrogen is sometimes used synomously with the term
"androgen receptors blocker" because antiandrogens
usually work by blocking the appropriate receptors, competing for
binding sites on the cell's surface, literally obstructing the
androgens' pathway. Also read article on Anti-androgens contributed by Dr.
Proctor.
- To remove the
effects of androgens:
1. Anti-androgen: binds the androgen recptor which inhibits
its action
2. 5-alpha-reductase inhibitors: less DHT means less potent
androgens
3. Androgen receptor(AR) downregulation: Less AR, obviously,
means there is less for the androgens to bind to and less
signaling. This can be done in many ways most of which are not
well understood. Inhibition of GSK-3beta is one way of doing
lowering the amount of AR that has been confirmed.
- Ascorbic
acid
- A technical
name for Vitamin C
- Catagen
- Refers to the
resting phase of the hair cycles.
- Calf-thymus extract
Calf-thymus
is synonymous with thymus gland. Thymus is a kind of lymphoid
organ that is essential for the development of immunological
functions of the body.
- Clobetasol
- Copper chloride
- Corticosteroid
- This
is a family of steroid hormones produced in the adrenal cortex.
Corticosteroids are involved in a variety of physiologic systems
such as stress response, immune response and regulation of
inflammation, and carbohydrate metabolism. It's indication for
hair loss is mainly as an anti-inflammatory agents for the scalp.
Long term use of corticosteroid products is not recommended as
this can "thin" the skin tissue and affect collagen
production.
- Dimethicone
- It is a kind
of silicone oil used to protect the skin against water-soluble
irritants.
- Finasteride (Proscar /
Propecia)
- Finasteride is
the generic name of the brand name drug Proscar. Proscar is
manufactured by Merck and is FDA approved for the treatment of
benign prostate enlargement. Clinical studies have shown that
patients who have been using Proscar have experienced a slow
down in hair loss and in some cases hair regrowth. Finasteride
is available both as an oral medication and a topical lotion.
Proscar is an oral medication that can be obtained with a
prescription only.
- It is
speculated that finasteride or Proscar slows down the
formation of DHT (Dehydrotestosterone), which is the main
culprit for hair loss. DHT is a form of male hormone . DHT is
formed when the male hormone testosterone interacts with the
enzyme 5-alpha reductase. DHT is problably many times more
potent than testosterone and is the main cause for hair loss.
- Glutamine
- It is a kind
of non essential amino acid. It is suggested that glutamine
maintains the integrity of gastrointestinal mucosa especially
during hypermetabolic phase of stree response. Glutamine
enhances cellular profliferation and may reduce the chances of
bacteria translocation from the gut and improve absorption
from the mucosa.
- Hair
Flapts
- This is a
surgical procedure that invloves removing hair-bearing strips
or patches to the balding area. Usually, the hair-bearing
stips or patches of skin are taken from the sides of your
head. The strips or patches are then rotate and suture to the
frontal balding area. The results may sometimes be unnatural
since the hair may be growing at an odd direction and the hair
may look unusually dense. This is another radical surgical
procedure that may carry greater risk of post-surgical
complications.
- Hair
Transplantation
- A surgical
procedure in which a surgeon removes hair grafts from the back
and the side of your head (also called the donor area or donor
hair) and surgically inserts the donor grafts into the balding
scalp. For some people, it may take several sessions of hair
transplantation before they see noticeable results. More info.
- Keratin

promote healthy hair growth.
- Polysorbates - 20, 60, 80
- This substance
is usually associated with fatty acids. It comes with several
series including polysorbates 20, polysorbates 40,
polysorbates 60 and polysorbates 80. This substance is used a
lot in hair care and other pharmaceutical products.

- It is a kind
of amino acid formed upon digestion of protein.
- Propylparaben

A ACIDS
- Retin-A is a
brand name topical gel or cream that most doctors prescripe to
patients for treating acne. The active ingredients in Retin-A
is some kind of vitamin acids or derivatievs. It has been
suggested that minoxidil when used in combination with Retin-A
will enhance penetration to the hair follicles and double the
effect of using minoxidil alone.
- Scalp
Lifts ( Hairlift)
- This is a
surgical procedure similar to scalp reduction except that
scalp lifts are more radical and extensive in nature. In scalp
lifts, a majority of the bald skin is removed and the
hair-bearing skin is then pulled together up toward the front
of your head. Scalp lift is usually complimented with hair
transplantation to create a natural hairline. Due to the
extensiveness of the procedure, scalp lifts often carry
greater risk of post-surgical complications.
- Scalp
Reduction
- Scalp
reduction is suitable for patients with large area of bald
scalp or bald spot at the crown. It is a surgical procedure
that involves removing bald skin from the top or the crown of
your scalp and then pulling the hair-bearing skin closer
together, thereby reducing the size of the bald spot. The
procedure is more extensive than hair transplantation.
Sometimes scalp reduction is performed in combination with
hair transplantation to achieve optimum results.
