Danazol: a drug sometimes linked to excess hair
growth
Dapelle is a brand of electric tweezer
DC: direct current
Dectronique: a Canadian manufacturer of electrolysis
equipment
Depilamax: a Canadian manufacturer of electrolysis
equipment
Depilation: the temporary removal of hair
Depilatories: substances used to dissolve hair
above the skin's surface
Depilex: a UK manufacturer of electrolysis equipment
Dermabrasion: a cosmetic procedure used to smooth
skin and reduce scars
Dermal papilla a tiny bulge at the root of a
hair, believed to be one of the primary targets in permanent hair
removal
Dermal sheath a lining around a hair
Dermatitis: also known as eczema
Dermatologist a doctor specializing in skin
and hair conditions
Dermis the deepest layers of the skin, where
the hair root is located
Dexamethosone: a steroid anti-inflammatory which
sometimes causes hair growth
Diabetes: a disease where the body improperly
produces insulin, sometimes linked to excess hair growth
Diathermy: another name for thermolysis
Diazoxide a drug sometimes linked to excess
hair growth
Diet is sometimes linked to excess hair growth,
especially in the extremely obese and extremely anorexic
Dilantin a drug sometimes linked to excess hair
growth
Diode : a semiconductive material which mainly
lets energy travel one direction and not the other. Light-Emitting
Diodes (LEDs) are used for the numeric displays on microwaves
and VCRS as well as for lasers.
Diomed makes the LaserLite pulsed diode array
laser
Direct current: also called DC, it is a type
of electrical energy that travels in one direction. The other
type is alternating current (AC). Direct current is used in the
Galvanic electrolysis method to cause a chemical reaction in the
hair follicle. Home needle electrolysis kits like One Touch use
direct current supplied by a 9-volt battery.
Discrette Plus is an electric epilator made
by Epilady
Discomfort due to hair removal varies greatly
by individual and body area. Electrolysis is generally considered
most painful, followed by laser, plucking, and waxing. Body areas
most prone to discomfort are underneath the nostrils, around the
lips, and the bikini zone.
Disease transmission via hair removal is quite
unlikely if practitioners observe universal precautions regarding
sanitation and sterility.
Disinfectant a solution used to kill bacteria.
Distorted hair follicles a relatively rare condition
in which the follicle is not straight. This condition can make
waxing and electrolysis more difficult and can lead to ingrown
hairs.
Doctors sometimes perform hair removal, usually
electrolysis or laser. Certain types of hair such as those in
moles or warts should be cleared only with a physicians's approval.
Some states require that doctors only can perform laser hair removal,
while others merely require a doctor to be present.
Do-it-yourself electrolysis involves using a
hand-held electrified needle unit such as the $30 Inverness One
Touch. The unit must have a needle to be permanent, and even then,
it is dofficult to achieve permanent results without causing pain
or even scarring.
Double-blind: a clinical testing method in which
neither patient nor doctor know what medication or procedure is
being used.
Draping: covering a work table or client with
paper of cloth prior to hair removal. This is done for sanitation
and for client
Drug treatment: excess hair can be increased
or decreased by certain drugs. These drugs often affect hormonal
levels. Consult a physician if a drug you are taking seems to
be causing increased hair growth.
Dry heat ovens: a method for sterilizing medical
equipment
Dynamic cooling: a method of epidermal cooling
which cools the skin with supercooled liquid immediately before
a laser pulse is applied. Dynamic cooling will probably eventually
replace messier options such as cooled gels and air cooling
